TAMOL PP

Agrochemical chemists, paper engineers, textile colorists, and leather technologists systematically prefer Tamol PP over conventional naphthalene sulfonate formaldehyde condensates (such as Tamol NN 8906 or Dispersant NNO), wood-derived lignosulfonates, and high-foaming monomeric surfactants because the benzene-based phenolic-urea backbone of Tamol PP lacks fused bicyclic naphthalene rings—imparting markedly superior ultraviolet (UV) lightfastness, paler intrinsic solution color, and strong hydrogen-bonding affinity for polar oxide, silicate, polyamide, and protein substrates. Furthermore, because Tamol PP (Tamol FB PP) exhibits almost zero surface-tension depression at the air-water interface (1% aqueous surface tension ~64 to 70 mN/m), Sodium Salt of a Phenol Sulfonic Acid Condensation Product is 100% non-foaming during high-energy wet bead milling, high-speed paper-machine white-water circulation, and jet dyeing, while maintaining full electrostatic dispersing activity across pH 1.0 to 13.0 and in hard waters exceeding 500 ppm CaCO3.

Supplied commercially by Ataman Kimya as a free-flowing, hygroscopic yellowish-brown powder (dry content ~95.0% w/w, aqueous pH 6.5 to 8.5 at 10% w/w, bulk density 450 to 650 g/L, and water solubility > 400 g/L at 20 °C), Tamol PP dissolves rapidly in cold or warm water to form clear, low-viscosity solutions free of abrasive insolubles. Matching the unique hydrogen-bonding plus electrostatic stabilization mechanism of Tamol PP with the target agrochemical active ingredient, emulsion polymerization recipe, papermaking furnish, or textile/leather bath ensures floc-free slurry fluidity, zero foam entrainment, and non-yellowing end-product performance with Tamol PP.

WHAT IS TAMOL PP?

Known across international chemical, agrochemical, papermaking, polymer, textile, and leather commerce as Tamol PP or Tamol FB PP (and in Turkish industrial trade as Tamol PP, Fenol Sülfonik Asit Kondensatı Sodyum Tuzu, or Anyonik Polimerik Dispersant ve Emülgatör Tamol PP), Tamol PP is a specialty water-soluble, non-foaming anionic polymeric dispersing agent, protective colloid, and technical emulsifier produced by BASF and supplied by Ataman Kimya as a free-flowing, hygroscopic yellowish-brown powder with approximately 95% dry solids content. Chemically, Tamol PP is defined as the sodium salt of a phenolsulfonic acid condensation product—specifically a co-polycondensate of hydroxybenzenesulfonic acid (phenolsulfonic acid), formaldehyde, phenol, and urea neutralized with sodium hydroxide (CAS No. 102980-04-1 / NLP No. 600-372-6; Tamol PP is also classified within the broader phenol sulfonic acid / sulfone / formaldehyde condensate family under CAS 9003-59-2 and CAS 50851-37-1).

Why the Phenolsulfonic Acid-Urea-Formaldehyde Architecture of Tamol PP Differs Fundamentally from Naphthalene Sulfonate Condensates:
Within the classic Tamol dispersing agent portfolio, procurement specialists and R&D chemists must clearly distinguish the phenolic-based Tamol PP from the naphthalene-based Tamol NN / NNO / MNS grades:

 Distinction of Tamol PP from Naphthalene Sulfonate Formaldehyde Condensates (e.g., Tamol NN 8906, Tamol NNO, Supragil MNS/90, CAS 9084-06-4 / 81065-51-2): Naphthalene sulfonate condensates are built from fused bicyclic C10H8 naphthalene rings that carry only hydrophobic aromatic planes and sulfonate groups (-SO3Na). Because bicyclic naphthalene rings absorb near-UV radiation (300–380 nm) strongly and oxidize into quinonoid chromophores, naphthalene sulfonate condensates turn yellow-brown when exposed to sunlight and lack hydrogen-bonding hydroxyl or amide groups. By contrast, Tamol PP (Phenolsulfonic Acid-Formaldehyde-Phenol-Urea Polymer Sodium Salt) is built from monocyclic C6H5OH phenolic rings bridged with urea (-NH-CO-NH-) and methylene (-CH2-) units. This gives Tamol PP three unique advantages: (a) Tamol PP provides vastly superior UV lightfastness and non-yellowing character (essential in white/pastel leather retanning, paper coatings, and light-colored polymer latices); (b) Tamol PP possesses dense hydrogen-bonding phenolic -OH and urea -NH-CO-NH- groups that bind tenaciously to polar pesticide crystals, mineral oxides, polyamide fibers, and leather collagen; and (c) Tamol PP delivers strong protective-colloid stabilizing power in emulsion polymerization and pitch control!

 Distinction of Tamol PP from Polyacrylate / Polycarboxylate Dispersants (e.g., Sokalan PA / Tamol 731): Aliphatic polycarboxylates rely on weak carboxylic acid groups (-COOH, pKa ~4.5–5.0) that lose their negative charge and precipitate below pH 5.0 or in high-calcium brines. Because Tamol PP carries aromatic sulfonate groups (-SO3- Na+, pKa < -1.0) alongside nonionic hydrogen-bonding phenolic/urea groups, Tamol PP remains 100% ionized, soluble, and active across the entire pH range from strongly acidic pH 1.0 (acidic leather tanning and pH 2.5 nylon stain-resist baths) to strongly alkaline pH 13.0!

 Distinction of Tamol PP from Surface-Active Monomeric Emulsifiers (SLS, LAS, Alkylphenol Ethoxylates): Unlike conventional soap emulsifiers that lower water surface tension to 30–35 mN/m and generate massive foam, Tamol PP (Tamol FB PP) is a non-surface-active polymeric protective colloid (surface tension ~64–70 mN/m at 1% w/w). In emulsion polymerization and high-shear slurry milling, Tamol PP stabilizes monomer droplets, polymer latex particles, and solid suspensions electrosterically with ZERO foaming and zero water-sensitivity migration in dried films.

CHEMICAL STRUCTURE, MOLECULAR ARCHITECTURE AND MULTIPOINT ADSORPTION CHEMISTRY

Understanding why Tamol PP acts simultaneously as a high-solids slurry dispersant, an emulsion polymerization protective colloid, a papermaking pitch-control agent, and a nylon/leather tanning auxiliary requires examining the four-functional-group macromolecular structure of Tamol PP:

 The Aromatic Phenyl Ring Core of Tamol PP (Hydrophobic & Pi-Pi Interaction Domain):
The backbone of Tamol PP consists of ortho- and para-linked benzene rings derived from phenol and 4-hydroxybenzenesulfonic acid (connected via covalent methylene -CH2- bridges, and in sulfone-modified variants of Tamol PP, -SO2- bridges). These planar sp2 aromatic rings in Tamol PP anchor onto hydrophobic organic pesticide crystals, carbon black, organic pigments, synthetic rubber latex particles (SBR, NBR, CR), and hydrophobic wood-resin pitch droplets via van der Waals dispersion forces and pi-pi stacking.

 The Phenolic Hydroxyl (-Ar-OH) Hydrogen-Bonding Donor/Acceptor Group in Tamol PP:
Every repeating ring in Tamol PP (Sodium Salt of a Phenol Sulfonic Acid Condensation Product) carries a covalently bound phenolic hydroxyl group (-OH, pKa ~9.5–10.0). At acidic and neutral pH (pH 1.0 to 8.5), the un-ionized phenolic -OH group of Tamol PP acts as a potent hydrogen-bond donor that forms strong chelate-like hydrogen bonds with carbonyl, amide, ester, nitrile, and silanol groups on polar pesticide crystals, kaolin/silica fillers, polyamide-6 / polyamide-6,6 (nylon) peptide linkages, and leather collagen fibers. Above pH 9.5, partial deprotonation of Tamol PP into phenolate anions (-Ar-O- Na+) further boosts the negative electrostatic charge density of Tamol PP in alkaline slurries!

 The Integrated Urea (-NH-CO-NH-) / Methylene-Urea Bridges of Tamol PP:
During the synthesis of Tamol PP, co-condensing urea (H2N-CO-NH2) with formaldehyde and phenolsulfonic acid incorporates polar ureido (-CH2-NH-CO-NH-CH2-) segments into the oligomeric backbone of Tamol PP. These urea linkages in Tamol PP increase backbone flexibility, suppress dark phenolic quinone discoloration (making Tamol PP powder light yellowish-brown rather than black-brown), and introduce dual N-H hydrogen-bond donors and C=O hydrogen-bond acceptors that dramatically strengthen protective-colloid adsorption of Tamol PP onto emulsion polymer droplets and wood-pitch resin globules.

 The Permanently Ionized Sodium Sulfonate (-SO3- Na+) Polyelectrolyte Corona of Tamol PP:
Each sulfonated phenolic ring in Tamol PP carries a strongly hydrophilic sodium sulfonate group (-SO3- Na+) that dissociates completely in water across pH 1.0 to 13.0. Once Tamol PP adsorbs onto a solid particle or emulsion droplet in a flat train-and-loop conformation, the outward-facing -SO3- anions of Tamol PP create a dense electrical double layer (zeta potential -40 to -60 mV) and a tightly bound hydration shell that prevents particle aggregation, reduces slurry viscosity by 75% to 95%, and stabilizes emulsions against mechanical shear and multivalent electrolyte shock (Ca2+, Mg2+, Al3+).

INDUSTRIAL PRODUCTION AND MANUFACTURING PROCESSES

Commercial Tamol PP (CAS 102980-04-1) is manufactured in corrosion-resistant glass-lined or Hastelloy reactors through a four-stage sulfonation, co-condensation, neutralization, and spray-drying process:

Step 1: Regioselective Sulfonation of Phenol to 4-Hydroxybenzenesulfonic Acid for Tamol PP: High-purity molten phenol (C6H5OH) is reacted with concentrated sulfuric acid (98% H2SO4) at 95 to 115 °C for 2 to 4 hours. Operating above 95 °C under thermodynamic control rearranges any initial ortho-isomer into >95% para-phenolsulfonic acid (4-hydroxybenzenesulfonic acid), leaving the two ortho positions (C-2 and C-6 relative to the phenolic -OH) open and activated for linear methylene-bridge polycondensation into Tamol PP.

Step 2: Staged Formaldehyde-Phenol-Urea Co-Polycondensation into Tamol PP: The para-phenolsulfonic acid intermediate is diluted with process water, combined with controlled stoichiometric charges of urea and additional phenol (or 4,4'-dihydroxydiphenylsulfone), and reacted with aqueous formaldehyde (37% formalin) at 80 to 110 °C for 3 to 6 hours to build the Tamol PP polymer chain. Protonated hydroxymethyl groups link the aromatic rings and urea nitrogens via covalent methylene bridges (-CH2- and -CH2-NH-CO-NH-CH2-) until the target oligomeric molecular weight distribution of Tamol PP (Mw ~2,200 to 5,000 g/mol) and viscosity are achieved, followed by vacuum/steam stripping to minimize residual free formaldehyde and free phenol in Tamol PP.

Step 3: Neutralization and Salt Conditioning of Tamol PP: The acidic polycondensate liquor is cooled and neutralized with aqueous sodium hydroxide (NaOH) to a neutral-to-weakly-alkaline pH of 6.8 to 8.2 (converting all -SO3H groups of Tamol PP into the sodium salt -SO3Na while leaving phenolic -OH groups protonated so they do not oxidize into dark quinones), and polished via filtration to remove any insoluble matter below 0.05%.

Step 4: High-Tower Atomization Spray Drying of Tamol PP (~95% Dry Solids): The concentrated ~45% aqueous solution of Tamol PP is spray-dried in a co-current tower (inlet air 175 to 210 °C, outlet air 85 to 95 °C) to yield a fine, rapidly soluble, yellowish-brown Tamol PP powder with a dry content of approximately 95.0% w/w (moisture <= 5.0% w/w).
Ataman Kimya supplies Tamol PP—alongside the broader portfolio of BASF Tamol, Sokalan, Wettol, and Agnique dispersing and wetting agents—from ready warehouse stocks in Turkey to domestic and international industrial manufacturers.

WHY EACH IMPORTANT PROPERTY OF TAMOL PP MATTERS IN PRACTICE

Formulators in emulsion polymerization, crop protection, papermaking, textile wet processing, and leather tanning rely on specific quantitative properties of Tamol PP because each parameter solves a distinct processing challenge:
- Phenolic -OH + Urea -NH-CO-NH- Hydrogen-Bonding Capacity of Tamol PP Combined with -SO3Na Electrostatic Charge: Standard naphthalene sulfonate condensates (like Tamol NN) can only adsorb onto strictly non-polar hydrophobic surfaces via aromatic pi-stacking and often desorb from polar pesticide crystals (such as carboxamides, triazolinones, sulfonylureas, or copper/sulfur fungicides), polar oxide pigments (TiO2, iron oxides), or hydrophilic wood-pitch colloids. Because Tamol PP carries both phenolic hydroxyl (-OH) and urea (-NH-CO-NH-) groups on every repeating unit, Tamol PP locks onto polar and semi-polar surfaces through multipoint hydrogen bonding while projecting its ionized -SO3- groups into water to create a -50 mV electrostatic barrier!
- High UV Lightfastness and Low Staining of Tamol PP (Monocyclic Phenolic-Urea vs. Bicyclic Naphthalene): When naphthalene sulfonate dispersants are used in white paper coatings, pale architectural pigment pastes, white SBR carpet backings, or white/pastel leather retanning, exposure to daylight UV causes the naphthalene rings to photo-oxidize into dark yellow-brown stains. The urea-bridged phenolsulfonic acid structure of Tamol PP resists UV photo-oxidation, preserving bright white and pastel shades.
- High Surface Tension (62 to 70 mN/m) and Zero Foaming of Tamol PP: In emulsion polymerization reactors, horizontal zirconia bead mills, and high-speed paper machines (running at 1,000 to 2,000 meters/minute), surfactant foam causes reactor fouling, pump cavitation, sheet pinholes, and mill overheating. Because Tamol PP barely lowers water surface tension (~66 mN/m), Tamol PP provides powerful colloidal stabilization with ZERO foam generation.
- Neutral Aqueous pH (6.5 to 8.5 at 10% w/w) and ~95% High Dry Content of Tamol PP: The neutral pH of Tamol PP prevents base-catalyzed hydrolysis of pH-sensitive agrochemical active ingredients (organophosphates, carbamates, esters) and monomer esters (vinyl acetate, acrylates) during emulsion polymerization, while the ~95% dry content of Tamol PP delivers high active polymer per kilogram shipped.

HOW DOES TAMOL PP WORK AT THE MOLECULAR AND INTERFACIAL LEVEL?

Tamol PP performs four distinct physicochemical roles depending on the industrial system:

 Protective-Colloid Stabilization by Tamol PP in Emulsion Polymerization and Synthetic Latices: During the aqueous emulsion polymerization of Styrene-Butadiene Rubber (SBR), Nitrile-Butadiene Rubber (NBR), Polychloroprene (CR), or Acrylic/Vinyl dispersions, Tamol PP (dosed at 0.3% to 2.5% phm on monomer weight) adsorbs onto the growing sub-micron polymer latex particles via its aromatic phenyl rings and hydrogen-bonding urea/phenolic groups. Because Tamol PP forms a hydrated, negatively charged polyelectrolyte shell (-45 to -55 mV zeta potential) without lowering air-water surface tension or forming new micellar nucleation sites during post-addition, Tamol PP prevents mechanical shear coagulation in pumps, steam-stripping columns, and compounding tanks without causing latex foaming!

 Electrosteric & Hydrogen-Bonded Slurry Deflocculation by Tamol PP in Agrochemicals (WP, WDG, SC) and Pigments: When solid pesticide active ingredients or inorganic/organic pigments are milled in water, Tamol PP anchors onto crystal faces via combined pi-pi stacking and phenolic/urea hydrogen bonding. The ionized sulfonate groups (-SO3- Na+) of Tamol PP establish a steep DLVO electrostatic repulsion barrier that breaks up particle flocs, cuts slurry yield stress by 80%–95%, inhibits Ostwald crystal growth during 54 °C storage, and drives rapid osmotic granule disintegration ('bloom') when WDG granules formulated with Tamol PP are diluted in field spray tanks.

 Colloidal Pitch & Sticky-Deposit Passivation by Tamol PP in Pulp and Paper Mills: During mechanical and chemical wood pulping and recycled-paper deinking, microscopic droplets of hydrophobic wood resin ('pitch'—composed of abietic/resin acids, fatty acids, and triglycerides) and synthetic adhesive 'stickies' agglomerate in the white-water circuit and deposit onto paper-machine forming wires, press felts, and drying cylinders, causing web breaks and paper holes. Dosing 0.05% to 0.30% w/w Tamol PP (on dry pulp weight) encapsulates sticky pitch and adhesive globules in a negatively charged, hydrophilic phenolic-sulfonate protective colloid shell—keeping them finely dispersed in the white water or fixing them harmlessly onto pulp fibers in the presence of papermaker's alum!

 Site-Blocking Reserve / Stain-Blocker Action of Tamol PP on Polyamide (Nylon) and Collagen (Leather): In acidic aqueous baths (pH 2.5 to 5.0), the protonated terminal amino groups (-NH3+) of polyamide-6 / polyamide-6,6 carpets and garments or chrome-tanned leather collagen attract the anionic sulfonate groups (-SO3-) of Tamol PP electrostatically, while the peptide amide bonds (-CO-NH-) form dense hydrogen bonds with the phenolic -OH and urea -NH-CO-NH- groups of Tamol PP. On nylon carpets/textiles, Tamol PP forms an invisible protective barrier that blocks terminal amine sites from being stained by acidic food/beverage dyes (coffee, red wine, fruit juice) and acts as a leveling/reserve agent when dyeing wool/nylon blends; in leather tanning, Tamol PP penetrates the hide cross-section uniformly to plump and retan white and pastel leathers without yellowing.

WHAT PROBLEMS CAN TAMOL PP HELP SOLVE?

Industrial chemists and plant engineers across six sectors use Tamol PP (Sodium Salt of a Phenol Sulfonic Acid Condensation Product) to solve persistent manufacturing problems:

Mechanical shear coagulation and excessive foam in synthetic rubber (SBR/NBR/CR) emulsion polymerization solved by Tamol PP
Conventional fatty-acid soap or lauryl sulfate emulsifiers generate massive foam during monomer stripping and fail to protect latex particles against high-shear pumping or electrolyte addition. Adding 0.5% to 2.0% phm Tamol PP provides foam-free protective-colloid stabilization that eliminates reactor wall coagulum and strainer plugging.

Wood-pitch agglomerates, sticky felt deposits, and sheet breaks on paper machines eliminated by Tamol PP
Hydrophobic wood pitch and recycled-paper adhesive stickies build up on paper-machine wires and press rolls, forcing costly machine shutdowns for solvent cleaning. Dosing Tamol PP into the pulp chest passivates pitch tackiness and keeps resin droplets stably dispersed even in hard water and alum-rich white water.

Flocculation, high millbase viscosity, and foaming in polar/semi-polar agrochemical SC, WDG, and WP formulations prevented by Tamol PP
Active ingredients containing polar amide, urea, triazole, or ester groups often desorb standard naphthalene sulfonates or foam excessively with monomeric surfactants. Tamol PP locks onto polar crystal surfaces via phenolic/urea hydrogen bonding and disperses them with zero foam.

UV yellowing of white leather, pale paper coatings, and textile auxiliaries prevented by substituting naphthalene sulfonates with Tamol PP
Naphthalene-based dispersants (SNF / Tamol NN) turn yellow-brown upon sunlight exposure. Because Tamol PP is synthesized from phenol, urea, and formaldehyde (zero bicyclic naphthalene rings), Tamol PP prevents UV yellowing in white shoes/upholstery leather and pale coatings.

Uneven dye strike ('barriness') in polyamide/wool blends and food-dye staining of nylon carpets controlled by Tamol PP
In dyeing wool/nylon blends with acid dyes, nylon absorbs dye much faster than wool at low temperatures, leaving uneven streaks. Tamol PP selectively occupies rapid-dyeing amine sites on nylon to ensure uniform, level shade build-up between wool and nylon, and Tamol PP serves as an economical stain-resist finish on nylon carpets.

Hydrolysis of sensitive active ingredients avoided by the neutral pH of Tamol PP
Many sulfonate and polyacrylate dispersants have high pH (9.5 to 11.0) that degrades base-sensitive pesticides or monomer esters. Tamol PP is buffered at a gentle neutral pH of 6.5 to 8.5.

 Tamol PP is extensively utilized as a non-foaming protective colloid and technical emulsifier in Emulsion Polymerization and Synthetic Rubber / Polymer Latex Stabilization (including SBR, NBR, CR, Acrylic, and Vinyl Dispersions).
 Tamol PP is used as a primary anionic dispersing and suspending agent in Agrochemical Crop Protection Formulations (specifically Wettable Powders WP, Water Dispersible Granules WDG / WG, and aqueous Suspension Concentrates SC).
 Also, Tamol PP is utilized in Pulp and Paper Manufacturing as a high-efficiency Wood-Pitch Control Dispersant, Sticky-Deposit Passivator, and Kaolin/CaCO3 Filler Slurry Dispersant.
 For Textile Wet Processing, Tamol PP is used as a Polyamide/Nylon Stainblocker, a Wool/Nylon Reserve and Leveling Auxiliary, and a Disperse/Acid Dye Dispersant.
 In Leather Tanning and Retanning, Tamol PP is employed as a Lightfast Phenolic Auxiliary and Replacement Syntan for White and Pastel Leathers.
 Furthermore, Tamol PP is utilized in the preparation of Aqueous Organic and Inorganic Pigment Dispersions, Sulfur/Accelerator Latex Curative Pastes, and Ceramic Slurries.
 Tamol PP is also used in Industrial Cleaning, Metal Treatment, and Specialty Construction Admixtures requiring a non-foaming, hard-water-stable phenolic sulfonate dispersant.

WHICH INDUSTRIES USE TAMOL PP?

- The Synthetic Rubber, Emulsion Polymerization, and Latex Compounding Industry relies on Tamol PP as a non-foaming protective colloid and latex stabilizer.
- The Agricultural Chemical and Crop Protection Formulation Industry utilizes Tamol PP to manufacture stable WP, WDG/WG, SC, and SE pesticide products.
- The Pulp, Paper, Tissue, and Packaging Board Manufacturing Industry uses Tamol PP for wood-pitch control, sticky passivation, and white-water stabilization.
- The Textile Dyeing, Carpet Finishing, and Fiber Auxiliary Industry deploys Tamol PP as a nylon stain-resist agent and wool/polyamide union-dyeing reserve auxiliary.
- The Leather Tanning, Retanning, and Crusting Industry uses Tamol PP (Phenolsulfonic Acid-Formaldehyde-Phenol-Urea Polymer Sodium Salt) as a UV-lightfast white and pastel syntan.
- The Pigment, Dyestuff, Coating, and Technical Ceramics Industry utilizes Tamol PP for high-solids, zero-foam aqueous slurry milling.

USE OF TAMOL PP IN EMULSION POLYMERIZATION, AGROCHEMICALS AND PAPERMAKING

- Emulsion Polymerization and Latex Stabilization with Tamol PP (0.3% to 2.5% phm on monomer/polymer solids): In the manufacture and post-stabilization of Styrene-Butadiene Rubber (SBR), Nitrile Rubber (NBR), Polychloroprene (CR), and styrene-acrylic/vinyl-acetate copolymer emulsions, Tamol PP acts as a non-foaming anionic protective colloid and secondary emulsifier. Tamol PP prevents coagulum formation on reactor walls and agitator blades during polymerization, prevents latex flocculation during vacuum/steam monomer stripping, and stabilizes compounded latices against mechanical shear and divalent electrolyte addition when ball-milled sulfur, zinc oxide, and mineral fillers are incorporated.
- Agrochemical Crop Protection Formulations with Tamol PP (WP, WDG / WG, and SC, 1.5% to 8.0% w/w): In Wettable Powders (WP, 2.5% to 6.0% w/w Tamol PP), Water Dispersible Granules (WDG, 4.0% to 8.0% w/w Tamol PP), and aqueous Suspension Concentrates (SC, 1.5% to 4.0% w/w Tamol PP), Tamol PP disperses polar and semi-polar herbicide, fungicide, and insecticide active ingredients (including phenylureas, triazines, carboxamides, strobilurins, neonicotinoids, sulfur, and copper fungicides). The neutral pH of Tamol PP (6.5–8.5) protects hydrolysis-sensitive active ingredients, while the non-foaming character of Tamol PP prevents millbase air entrainment.
- Pulp and Paper Pitch Control & Sticky Passivation with Tamol PP (0.05% to 0.40% w/w on dry pulp): Metered as a 5%–20% aqueous solution of Tamol PP into the groundwood, thermomechanical (TMP), sulfite/kraft pulp chest, or recycled-fiber deinking loop, Tamol PP adsorbs onto tacky wood-resin pitch globules and synthetic pressure-sensitive adhesive stickies, detackifying their surfaces and keeping them colloidally dispersed so they cannot agglomerate on forming wires, press felts, or calender rolls.

USE OF TAMOL PP IN TEXTILE DYEING, LEATHER SYNTANS AND PIGMENT SLURRIES

- Textile Polyamide (Nylon) Stain-Blocker & Wool/Nylon Dye Reserve Agent with Tamol PP (0.5% to 3.0% owf — on weight of fiber): In dyeing wool/polyamide (nylon) blends with anionic acid or metal-complex dyes at pH 4.0–5.5, unmodified nylon fibers dye much more rapidly than wool at 40–70 °C, leaving the wool pale. Adding 0.8% to 2.5% owf Tamol PP to the dyebath allows the sulfonated phenolic-urea oligomer of Tamol PP to bind reversibly to the protonated amine sites on the nylon fiber, restraining ('reserving') initial dye uptake on nylon so both wool and nylon achieve a uniform, solid union shade! Applied at pH 2.5–3.5 as an aftertreatment on nylon carpets (1.5% to 3.0% owf), Tamol PP permanently blocks amine sites against acid food-dye stains without yellowing under UV light.
- Leather Tanning & Lightfast White/Pastel Retanning Syntan with Tamol PP (1.5% to 6.0% on shaved weight): Used in chrome-tanned and vegetable-tanned leather processing as a lightfast auxiliary and replacement phenolic-urea syntan, Tamol PP disperses vegetable tannins to accelerate hide penetration, neutralizes and buffers chrome leather uniformly, and retans white and pastel shoe/garment/automotive leathers with tight grain and high UV yellowing resistance.
- Pigment, Dye, and Curative Slurry Milling with Tamol PP (2.0% to 15.0% on dry solid weight): Tamol PP disperses inorganic oxides, organic pigments, disperse/vat dyes, and 50%–60% aqueous sulfur/ZnO/accelerator rubber curatives into low-viscosity, foam-free pastes.

FORMULATION AND PROCESS CONSIDERATIONS WHEN USING TAMOL PP

To achieve optimal performance when formulating or processing with Tamol PP, plant engineers and R&D chemists should observe four practical rules:
 Dissolving Hygroscopic Spray-Dried Tamol PP Powder Without Lumping: Because Tamol PP has a high ~95% dry content and strong hydrogen-bonding phenolic/urea groups, dumping a large mass of dry Tamol PP powder all at once into stagnant cold water can form a sticky gel skin around undissolved powder lumps. Always sift or meter Tamol PP slowly into the vortex of briskly agitated water (20 to 50 °C) over 3 to 5 minutes, where Tamol PP dissolves completely into a clear yellowish-brown solution up to 40%–45% w/w solids.
 Pairing Tamol PP with a Monomeric Wetting Agent in Dry Agrochemical WP and WDG Recipes: Because Tamol PP has a surface tension of 62–70 mN/m (zero wetting power at the air-water interface, which is why Tamol PP is 100% non-foaming), dry WP powders and WDG granules formulated with Tamol PP as the primary dispersant (3% to 8% w/w) should include 1.5% to 3.0% w/w of a monomeric wetting agent (such as sodium diisopropyl/dibutyl naphthalene sulfonate or sodium dioctyl sulfosuccinate) alongside Tamol PP to ensure < 20-second powder wetting in CIPAC MT 53.3 tests.
 
 pH Optimization for Tamol PP in Textile Nylon Reserve vs. Slurry Dispersion: When using Tamol PP as a particulate dispersant in agrochemical SCs, pigment pastes, or paper slurries, Tamol PP functions across the entire pH range (pH 2 to 12, typically pH 6.5–9.0). However, when using Tamol PP as a substantive stain-blocker or reserve agent on polyamide (nylon) fibers or leather collagen, adjust bath pH to 2.5–5.0 (with formic, acetic, or citric acid) so the fiber's amino groups are protonated (-NH3+) to attract the anionic sulfonate groups of Tamol PP!
 Avoiding Direct Contact of Tamol PP with Cationic Surfactants and Iron Salts: Never mix Tamol PP directly with cationic quaternary ammonium surfactants or cationic fixing agents (which precipitate an insoluble coacervate with Tamol PP), and avoid soluble ferric iron (Fe3+) contamination in white textile/leather applications using Tamol PP (as phenolic -OH groups form purple-brown chelate complexes with free Fe3+ ions; adding 0.1%–0.2% EDTA or sodium gluconate chelator prevents iron discoloration).

TYPICAL USE LEVELS AND INITIAL FORMULATION APPROACHES FOR TAMOL PP

Typical commercial dosage levels for Tamol PP (on an as-supplied ~95% dry powder basis) depend on the industrial application and substrate surface area:
- In Emulsion Polymerization & Synthetic Rubber Latex Stabilization (SBR, NBR, CR, Acrylics), Tamol PP is dosed at 0.3% to 2.5% phm (parts per hundred monomer/dry polymer weight) added in the polymerization charge or post-added as a 15%–25% aqueous Tamol PP solution prior to monomer stripping and compounding.
- In Agrochemical Wettable Powders (WP) and Water Dispersible Granules (WDG / WG), Tamol PP is incorporated at 3.0% to 8.0% w/w (typically 4.0% to 6.5% w/w Tamol PP paired with 1.5%–2.5% monomeric wetting agent).
- In Agrochemical Suspension Concentrates (SC) and Suspo-Emulsions (SE), Tamol PP is utilized at 1.5% to 4.5% w/w (15 to 45 g/L Tamol PP in the aqueous millbase, paired with 1.5%–2.5% nonionic EO-PO block copolymer or acrylic graft polymer).
- In Pulp & Paper Pitch Control and Sticky-Deposit Passivation, Tamol PP is applied at 0.05% to 0.35% w/w on bone-dry pulp weight (0.5 to 3.5 kg of Tamol PP per metric ton of dry pulp, metered continuously into the pulp chest or white-water loop).
- In Textile Wool/Nylon Dyeing Reserve & Leveling Auxiliaries, Tamol PP is used at 0.5% to 2.5% owf (on weight of fiber) in the dyebath at pH 4.0–5.5, and at 1.5% to 3.5% owf Tamol PP at pH 2.5–3.5 for nylon carpet stain-resist finishing.
- In Leather Tanning & Lightfast White/Pastel Retanning Syntans, Tamol PP is dosed at 1.5% to 6.0% w/w on shaved hide weight.
- In Aqueous Pigment, Filler (Kaolin/CaCO3/TiO2), and Latex Curative (Sulfur/ZnO) Slurries, Tamol PP is employed at 1.0% to 5.0% w/w on dry solid weight.
The four laboratory and pilot frameworks below illustrate preliminary R&D evaluation protocols for Tamol PP by qualified technical personnel.

EXAMPLE 3: EMULSION POLYMERIZATION AND MECHANICAL SHEAR STABILIZATION OF A CARBOXYLATED STYRENE-BUTADIENE (X-SBR) OR NITRILE (NBR) LATEX WITH TAMOL PP

Purpose: To evaluate reactor coagulum suppression, foam-free monomer stripping, and high-speed mechanical shear stability when using Tamol PP as the anionic protective-colloid co-emulsifier in an emulsion polymerization latex.
Initial aqueous emulsion polymerization recipe with Tamol PP (parts per 100 parts total monomer, phm):
- Monomer Feed (e.g., 1,3-Butadiene 42.0 phm + Styrene 55.0 phm + Acrylic/Itaconic Acid 3.0 phm = 100.0 phm total monomer): 100.0 phm

EXAMPLE 4: TEXTILE WOOL/POLYAMIDE (NYLON) UNION DYEING RESERVE AND NYLON CARPET STAIN-RESIST EVALUATION WITH TAMOL PP

Purpose: To evaluate nylon amine-site reservation (preventing over-dyeing of the nylon component in an 80/20 wool/nylon carpet yarn blend) and coffee/red-wine acid-stain blocking on polyamide-6,6 carpet using Tamol PP.
Initial dyebath / aftertreatment test parameters using Tamol PP (per 100.0 g of 80/20 Wool/Nylon-6,6 yarn at 15:1 liquor ratio = 1,500 mL bath):
- Wool/Nylon-6,6 Blended Carpet Yarn (80% wool / 20% polyamide): 100.0 g
- Tamol PP Powder (Reserve & Stain-Blocking Agent, dosed at 1.5% owf = 1.50 g Tamol PP): 1.50 g

- Acetic Acid / Sodium Acetate Buffer (to pH 4.5 for union dyeing, or Citric Acid to pH 2.8 for carpet stainblocker aftertreatment with Tamol PP): to target pH
- Acid Milling Dye Combination (0.8% owf): 0.80 g
Laboratory evaluation procedure:
- Set the dyebath at 40 °C with water, pH 4.5 buffer, 0.30 g chelator, and 1.50 g (1.5% owf) Tamol PP. Circulate with the 100.0 g wool/nylon yarn for 10 minutes so Tamol PP pre-adsorbs onto the rapid-dyeing nylon amine sites, then add the dissolved acid dyes, ramp at 1.0 °C/min to 98 °C, and hold for 45 minutes.
- Compare the dyed wool and nylon strands colorimetrically (Delta-E between wool and nylon): verify that 1.5% owf Tamol PP achieves a balanced, solid union shade (whereas without Tamol PP, the nylon dyes 3 times darker than the wool!).
- For the Carpet Stain-Resist Test (AATCC Test Method 175) with Tamol PP: Treat undyed nylon-6,6 carpet pile with 2.5% owf Tamol PP at pH 2.8 and 75 °C for 20 minutes, rinse, dry, and challenge with FD&C Red No. 40 (Kool-Aid / red wine test) for 24 hours; verify stain rating >= 8.5–9.0 on the AATCC Red 40 stain scale and Xenon-arc UV lightfastness (ISO 105-B02) >= Grade 4–5 with no phenolic yellowing from Tamol PP.

COMPATIBILITY AND INCOMPATIBILITY OF TAMOL PP

Evaluating chemical and ionic compatibility is essential when formulating Tamol PP into multi-component agrochemical, polymer, paper, textile, or leather baths:
- Full Compatibility of Tamol PP with Anionic Surfactants and Dispersants: Because Tamol PP is strongly anionic (-SO3- Na+), Tamol PP is 100% compatible with all other anionic surfactants and polymeric dispersants—including naphthalene sulfonate condensates (Tamol NN, Supragil MNS/90), monomeric alkylnaphthalene sulfonate wetters (Supragil WP, Supragil RM/210-EI), linear alkylbenzene sulfonates (LAS), lauryl ether sulfates, dioctyl sulfosuccinates (DOSS), phosphate esters, lignosulfonates, polycarboxylates (Sokalan CP 5), and anionic acid/direct/reactive textile dyes and synthetic leather tannins.
- Full Compatibility of Tamol PP with Nonionic Surfactants and Protective Colloids: Tamol PP is fully miscible and synergistic with fatty alcohol ethoxylates, EO-PO block copolymers (Pluronic / Synperonic), alkyl polyglucosides (APGs), polyvinyl alcohol (PVA), polyvinylpyrrolidone (PVP), xanthan gum, and CMC.
- Direct Incompatibility of Tamol PP with Cationic Surfactants, Cationic Dyes, and Cationic Polymers: Never mix concentrated Tamol PP directly with cationic quaternary ammonium surfactants, cationic basic dyes, or high-charge cationic polyamine/polyDADMAC flocculants at equimolar ratios, as electrostatic ion-pairing (-SO3- of Tamol PP with +NR4) precipitates an insoluble coacervate gum. (Note: In papermaking white water, dilute Tamol PP is added first to disperse pitch onto fibers before cationic retention aids or alum are dosed downstream).
- Interaction of Tamol PP with Ferric Iron Salts (Fe3+) and Strong Oxidizers: Like all phenolic derivatives containing free aromatic -OH groups, Tamol PP forms colored (purple-brown) coordination complexes with free dissolved ferric ions (Fe3+). In color-critical white paper, white textile, or white leather applications using Tamol PP, use iron-free water or add 0.05%–0.20% of a chelating agent (EDTA, DTPA, or Sodium Gluconate). Keep dry Tamol PP powder away from strong oxidizing agents (concentrated nitric acid, hypochlorites, peroxides).

SIMILAR PRODUCTS AND ALTERNATIVES TO TAMOL PP

When selecting an anionic polymeric dispersant, protective colloid, or tanning/textile auxiliary, formulators compare Tamol PP (Phenolsulfonic Acid-Formaldehyde-Phenol-Urea Polymer Sodium Salt, CAS 102980-04-1) against naphthalene sulfonate formaldehyde condensates (Tamol NN / Supragil MNS), lignosulfonates, polyacrylates/polycarboxylates, and styrene-maleic anhydride (SMA) copolymers.

TAMOL PP AND NAPHTHALENE SULFONATE FORMALDEHYDE CONDENSATES (TAMOL NN 8906 / DISPERSANT NNO / SUPRAGIL MNS)

Naphthalene Sulfonate Formaldehyde Condensates (CAS 9084-06-4 / 81065-51-2) are built from bicyclic naphthalene rings lacking hydroxyl or urea functional groups.
While naphthalene sulfonate condensates provide strong hydrophobic pi-pi stacking on strictly non-polar crystals and carbon black, they yellow severely under UV sunlight and lack hydrogen-bonding groups. Tamol PP (built from phenolsulfonic acid, phenol, urea, and formaldehyde, CAS 102980-04-1) provides three decisive advantages over Tamol NN / SNF: (1) Tamol PP delivers far higher UV lightfastness (non-yellowing on white leather, nylon, and paper); (2) Tamol PP provides strong hydrogen-bonding via phenolic -OH and urea -NH-CO-NH- groups onto polar pesticides, polyamide fibers, and wood pitch; and (3) Tamol PP offers superior protective-colloid action in emulsion polymerization!

TAMOL PP AND SODIUM / CALCIUM LIGNOSULFONATES (CAS 8061-51-6)

Lignosulfonates are dark brown wood-pulping by-products containing 5% to 25% reducing wood sugars and variable botanical impurities.
Lignosulfonates stain textiles, paper, and leather dark brown, generate foam, ferment in liquid storage, and have weak protective-colloid efficiency in emulsion polymerization and pitch control. Synthetic Tamol PP is 100% sugar-free, non-fermenting, 100% non-foaming, pale yellowish-brown in solution, and delivers consistent molecular weight and dispersing power.

TAMOL PP AND SODIUM POLYACRYLATE / POLYCARBOXYLATE DISPERSANTS (SOKALAN PA / SOKALAN CP)

Sodium Polyacrylates and Acrylic-Maleic Copolymers carry weak carboxylic acid groups (-COO- Na+, pKa ~4.5–5.0) along an aliphatic chain.
Below pH 5.0 (such as in acidic leather tanning at pH 3.5, nylon stain-blocking at pH 2.8, or alum-rich acidic papermaking at pH 4.5), polyacrylates protonate into uncharged -COOH and lose their dispersing power or precipitate with aluminum/chromium ions. Tamol PP carries strong sulfonate groups (pKa < -1.0) that remain 100% ionized and soluble down to pH 1.0 and in the presence of papermaker's alum and chrome tanning salts.

TAMOL PP AND STYRENE-MALEIC ANHYDRIDE (SMA) / DIISOBUTYLENE-MALEIC COPOLYMERS

Hydrolyzed Styrene-Maleic Anhydride (SMA) and Olefin-Maleic Anhydride sodium/ammonium salts are comb-like polymeric dispersants used in coatings and agrochemicals.
However, SMA copolymers are insoluble below pH 5.5, generate moderate foam, and cost 2 to 3 times more per kilogram than Tamol PP. Tamol PP provides zero-foam dispersion and protective-colloid stabilization across pH 1.0 to 13.0 at a significantly more economical cost-in-use.

TAMOL PP AND MONOMERIC ALKYLNAPHTHALENE / DIALKYL SULFOSUCCINATE WETTING AGENTS

Monomeric wetting surfactants (such as Supragil WP or sodium dioctyl sulfosuccinate DOSS) lower surface tension to 30–35 mN/m for rapid wetting, but foam heavily and cannot stabilize suspensions or latices long-term. Tamol PP is a non-foaming polymeric dispersant (surface tension ~66 mN/m); in dry agrochemical WP and WDG formulations, pairing 4%–6% Tamol PP with 1.5%–2.5% monomeric wetting agent achieves both rapid wetting and long-term suspension stability.

Hygroscopic Moisture Pickup and Caking Prevention for Tamol PP: Because Tamol PP is spray-dried to a very high ~95% dry solids content and contains strongly hydrophilic sodium sulfonate (-SO3Na) and urea (-NH-CO-NH-) groups, dry Tamol PP powder is distinctly hygroscopic when exposed to open humid air (> 55%–60% relative humidity)! If bags of Tamol PP are left open, Tamol PP rapidly absorbs atmospheric moisture and cakes into a sticky crust or hard lump. 

Always keep containers of Tamol PP tightly closed when not in use, heat-seal or tightly tie inner polyethylene bag liners immediately after partial dispensing of Tamol PP, and do not stack pallets of Tamol PP more than two high in warm warehouses. Note that if physical caking of Tamol PP occurs without chemical contamination, the lumps of Tamol PP dissolve completely in warm water with zero loss of dispersing or emulsifying performance. When stored unopened in its original moisture-proof packaging below 35 °C, Tamol PP has a certified shelf life of at least 24 months from the date of manufacture.
Safe Handling, Dust Control, and Environmental Spill Containment for Tamol PP: Handle dry Tamol PP powder at charging hoppers and weighing stations equipped with local exhaust dust extraction (LEV) to avoid generating airborne Tamol PP dust. Do not handle Tamol PP powder close to food, beverages, or animal feed unless the specific process and regulatory status permit such use. Never sweep dry spills of Tamol PP with brooms or compressed air; collect spilled Tamol PP powder using a HEPA-filtered industrial vacuum cleaner or damp-shovel into labeled recovery containers, and wash residual trace films of Tamol PP with water (noting that wet Tamol PP solutions make smooth floors slippery). Prevent concentrated spills or washings of Tamol PP from entering storm drains or surface waters.

FIRST AID MEASURES AND SAFETY INFORMATION FOR TAMOL PP

First Aid Measures for Tamol PP (Phenolsulfonic Acid-Formaldehyde-Phenol-Urea Polymer Sodium Salt, CAS 102980-04-1):
- Inhalation of Tamol PP Dust: If airborne dust of Tamol PP is inhaled during bag dumping or dry blending, move the exposed person immediately into fresh air and keep them warm and at rest. Have the person blow their nose gently and rinse the mouth and throat with clean water to clear Tamol PP dust from the upper respiratory tract; seek medical attention if coughing or respiratory irritation persists.
- Eye Contact with Tamol PP: Fine hygroscopic Tamol PP sulfonate powder entering the eyes can cause moderate mechanical and chemical eye irritation, redness, and watering. Immediately flush the eyes exposed to Tamol PP with plenty of lukewarm low-pressure running water or sterile isotonic eyewash saline for at least 15 minutes while holding the eyelids wide open and removing contact lenses if present; consult an ophthalmologist if redness or discomfort persists.
- Skin Contact with Tamol PP: Remove clothing and shoes contaminated with Tamol PP, brush off dry Tamol PP powder, and wash affected skin thoroughly with mild soap and plenty of running water. Seek medical advice if skin irritation occurs, and launder work clothing before reuse.
- Ingestion of Tamol PP: If Tamol PP is accidentally swallowed, rinse the mouth thoroughly with water and give 1 to 2 glasses of water to drink if the person is fully conscious. Never give anything by mouth to an unconscious person, do not induce vomiting after swallowing Tamol PP unless directed by medical personnel, and consult a physician if discomfort develops.

Workplace Safety, GHS Classification, and Toxicological Profile of Tamol PP:
Tamol PP exhibits low acute systemic toxicity (rat acute oral LD50 > 2,000 to > 5,000 mg/kg bw; acute dermal LD50 > 2,000 mg/kg bw) and is non-sensitizing and non-mutagenic in bacterial Ames tests. Because the aqueous pH of Tamol PP is neutral (pH 6.5–8.5) and residual monomers are tightly controlled, Tamol PP presents a favorable occupational profile; always consult Section 2 of the current batch Safety Data Sheet of Tamol PP for specific GHS classification details.

Personal Protective Equipment (PPE) and Fire-Fighting Measures for Tamol PP:
- Workplace PPE for Tamol PP: Wear tightly fitting dust-proof safety goggles (EN 166), impervious nitrile or butyl rubber gloves (EN 374), long-sleeved protective workwear, and a P2 / N95 particulate dust respirator (EN 149) when handling open bags of Tamol PP.
- Fire-Fighting Measures for Tamol PP: Tamol PP is a non-flammable solid under normal conditions, though finely dispersed airborne organic dust clouds of Tamol PP in enclosed equipment can present a dust deflagration risk if exposed to high-energy ignition sources (ground pneumatic transfer lines). Extinguish fires involving Tamol PP using water fog/spray, alcohol-resistant foam, dry chemical powder (ABC), or CO2. Thermal decomposition of Tamol PP above 260 °C releases carbon oxides (CO, CO2), nitrogen oxides (NOx), and sulfur oxides (SOx); firefighters must wear self-contained breathing apparatus (SCBA).

Commercial Packaging and Transport Logistics for Tamol PP:
- Tamol PP is packed in 20 kg and 25 kg net multi-wall bags with sealed inner polyethylene (PE) moisture-barrier liners (palletized on shrink-wrapped ISPM-15 wooden pallets).
- Tamol PP is also available in 500 kg to 800 kg net PE-lined Flexible Intermediate Bulk Containers (FIBC / big bags).
Transport Classification of Tamol PP: Tamol PP is Not Regulated as Dangerous Goods for road (ADR/RID), sea (IMDG), or air (IATA) transport (UN Number: Not Regulated; Hazard Class: None; Packing Group: None; Marine Pollutant: No; Customs HS Code: 3402.39 / 3809.92 / 3202.10).

WHAT SHOULD BE CONSIDERED WHEN PURCHASING TAMOL PP?

When sourcing Tamol PP from Ataman Kimya for emulsion polymerization, agrochemical formulations, papermaking pitch control, textile dyeing, or leather retanning, procurement and R&D teams should specify six key technical parameters for Tamol PP in their Request for Quotation (RFQ):
 Target Industrial Application for Tamol PP: Specify whether Tamol PP will be used in emulsion polymerization (SBR, NBR, CR, acrylics), agrochemical formulations (WP, WDG/WG, SC), pulp and paper pitch/sticky control, textile nylon reserve/stain-blocking, leather white/pastel retanning, or pigment/filler slurry dispersion.

 Exact Chemical Identity and CAS Registry Number of Tamol PP: Confirm that your process requires the phenolic-urea-formaldehyde sulfonate polymer Tamol PP / Tamol FB PP (CAS 102980-04-1 / CAS 9003-59-2 / CAS 50851-37-1) rather than a naphthalene-based Tamol NN grade (especially when UV lightfastness, neutral pH 6.5–8.5, or nylon/collagen hydrogen bonding is required from Tamol PP).

 Dry Solids Content and pH Specification of Tamol PP: Verify required Dry Content of Tamol PP (~95.0% w/w, moisture <= 5.0%–7.0%), 10% aqueous pH range (6.5 to 8.5), and 325-mesh water-insoluble limit (<= 0.10%).

 Trace Iron Ceiling in Tamol PP (for White Textile, Paper & Leather Users): If purchasing Tamol PP for bright white leather retanning, nylon carpet stain-blocking, or high-brightness paper coatings, specify low trace iron limits (or request co-supplied Sodium Gluconate / EDTA iron chelators alongside Tamol PP).

 Regulatory & Indirect Food-Contact Clearances for Tamol PP: Specify if US EPA 40 CFR 180.910 / 180.920 agrochemical inert compliance, FDA 21 CFR 176.170 / 176.210 / BfR XXXVI food-packaging paper compliance, or EU REACH documentation is required for Tamol PP.

 Packaging Format, Order Volume, and Documentation for Tamol PP: Specify moisture-barrier 20–25 kg PE-lined bags or FIBC big bags of Tamol PP, spot pallet quantity, annual forecast, and required Tamol PP TDS, 16-section GHS SDS, and batch COA documents.

FREQUENTLY ASKED QUESTIONS ABOUT TAMOL PP

 What is Tamol PP and what is its chemical composition?
Tamol PP (also known as Tamol FB PP, CAS 102980-04-1) is a water-soluble, non-foaming anionic polymeric dispersing agent, protective colloid, and technical emulsifier produced by BASF. Chemically, Tamol PP is the sodium salt of a phenolsulfonic acid-formaldehyde-phenol-urea condensation polymer supplied as a hygroscopic yellowish-brown spray-dried powder with approximately 95% dry solids content and a neutral aqueous pH of 6.5 to 8.5.

 How does Tamol PP differ chemically and functionally from Tamol NN (Naphthalene Sulfonate Condensate)?
Tamol NN grades (CAS 9084-06-4) are made from bicyclic naphthalene sulfonic acid condensed with formaldehyde; they contain no hydroxyl or urea groups and yellow rapidly under UV light. By contrast, Tamol PP (CAS 102980-04-1) is made from monocyclic phenolsulfonic acid co-condensed with phenol, urea, and formaldehyde. This gives Tamol PP much higher UV lightfastness (non-yellowing), neutral pH (6.5–8.5), and dense phenolic (-OH) and urea (-NH-CO-NH-) hydrogen-bonding groups that anchor strongly onto polar pesticides, polyamide fibers, leather collagen, wood pitch, and polymer latex particles.

 Why is Tamol PP completely non-foaming during wet bead milling, papermaking, and emulsion polymerization?
Unlike monomeric surfactants (such as SLS or alkylbenzene sulfonates) which pack at the air-water interface and drop surface tension to 30–35 mN/m, Tamol PP is a hydrophilic multi-ring polyelectrolyte that stays in the bulk water and solid-liquid interface, leaving air-water surface tension at 62 to 70 mN/m (nearly identical to pure water at 72.8 mN/m). Consequently, Tamol PP generates 0 to 5 mm of Ross-Miles foam, preventing air entrainment in horizontal bead mills, paper machines, and latex stripping columns.

 How does Tamol PP function in emulsion polymerization and synthetic rubber latex stabilization?
In the manufacture of Styrene-Butadiene Rubber (SBR), Nitrile Rubber (NBR), Polychloroprene (CR), and acrylic/vinyl polymer dispersions (dosed at 0.3% to 2.5% phm), Tamol PP adsorbs onto monomer droplets and growing polymer latex particles as an electrosteric protective colloid (-45 to -55 mV zeta potential). Tamol PP prevents reactor wall coagulum, stabilizes the latex during vacuum/steam monomer stripping without foaming, and protects compounded latices against mechanical shear and divalent cation shock.

 How is Tamol PP used in agrochemical Wettable Powders (WP), Water Dispersible Granules (WDG), and Suspension Concentrates (SC)?
Dosed at 3.0% to 8.0% w/w in WP and WDG formulations (paired with 1.5%–2.5% of a monomeric wetting agent) or at 1.5% to 4.5% w/w in liquid SC millbases, Tamol PP anchors onto polar and semi-polar pesticide crystals via combined pi-pi stacking and phenolic/urea hydrogen bonding. The neutral pH of Tamol PP (6.5–8.5) prevents hydrolysis of sensitive active ingredients, while its electrostatic repulsion slashes millbase viscosity and maintains >= 90%–96% CIPAC suspensibility.

 How does Tamol PP control wood-pitch and sticky deposits in pulp and paper mills?
During mechanical/chemical pulping and recycled-paper deinking, hydrophobic wood-resin pitch and adhesive stickies agglomerate and foul paper-machine forming wires and press felts. Adding 0.05% to 0.35% w/w Tamol PP (0.5 to 3.5 kg per ton of dry pulp) encapsulates tacky pitch droplets in a negatively charged, hydrophilic protective-colloid shell, detackifying the resin and keeping it harmlessly dispersed in white water across acidic (alum-rich) and neutral/alkaline papermaking systems.

 Why is Tamol PP used in dyeing wool/nylon textile blends and in nylon carpet stain-blocking?
In acidic dyebaths (pH 2.5 to 5.5), the anionic sulfonate (-SO3-) and hydrogen-bonding phenolic/urea groups of Tamol PP bind substantively to protonated terminal amine sites (-NH3+) on polyamide (nylon) fibers. In wool/nylon union dyeing (0.5% to 2.5% owf), Tamol PP restrains rapid dye strike on the nylon so wool and nylon dye to an even, matching shade; on nylon carpets (1.5% to 3.5% owf at pH 2.8), Tamol PP permanently blocks amine sites against acid food and beverage stains (coffee, wine, soft drinks) without UV yellowing.

 Why is Tamol PP preferred as a syntan in white and pastel leather retanning?
Unlike naphthalene sulfonate syntans (which oxidize into yellow-brown stains under sunlight) or natural vegetable tannins (which darken leather), the urea-bridged phenolsulfonic acid structure of Tamol PP (used at 1.5% to 6.0% on shaved hide weight) penetrates chrome-tanned leather uniformly to give a tight, full grain with high ISO 105-B02 UV lightfastness.

 Why must bags of Tamol PP be kept tightly sealed against warehouse humidity?
Because Tamol PP is spray-dried to a high ~95% dry solids content and contains strongly water-attracting sulfonate and urea groups, dry Tamol PP powder is hygroscopic when exposed to relative humidity above 55%–60%. Resealing the inner polyethylene liner bag immediately after dispensing Tamol PP prevents moisture pickup and caking; if physical lumps form, they remain 100% water-soluble and chemically active.

 How can industrial buyers and formulators source Tamol PP and request COA, TDS, and SDS documents from Ataman Kimya?
Customers can procure Tamol PP (CAS 102980-04-1) in moisture-barrier 20 kg and 25 kg polyethylene-lined bags or palletized bulk shipments—supported by batch-specific Certificates of Analysis (COA), Technical Data Sheets (TDS), and GHS/CLP Safety Data Sheets (SDS)—directly from Ataman Kimya by calling +90 216 577 10 10 or emailing info@atamankimya.com.

TAMOL PP – TECHNICAL SUMMARY

Tamol PP—known across global industrial commerce as Tamol PP, Tamol FB PP, Sodium Salt of a Phenol Sulfonic Acid Condensation Product, Phenolsulfonic Acid-Formaldehyde-Phenol-Urea Polymer Sodium Salt, and Fenol Sülfonik Asit Kondensatı Sodyum Tuzu, and identified under CAS No. 102980-04-1 (alongside CAS 9003-59-2 / CAS 50851-37-1, NLP No. 600-372-6)—is a water-soluble, 100% non-foaming, UV-lightfast anionic polymeric dispersing agent, protective colloid, and technical emulsifier with the representative oligomeric formula (C6H5NaO4S · CH2O · C6H6O · CH4N2O)x (weight-average molecular weight Mw ~1,500 to 8,000 g/mol). Synthesized via the para-selective sulfonation of phenol followed by co-polycondensation with formaldehyde, phenol, and urea and neutralization with sodium hydroxide, Tamol PP combines aromatic phenyl rings with hydrogen-bonding phenolic hydroxyl (-OH) and urea (-NH-CO-NH-) groups and permanently ionized sodium sulfonate groups (-SO3- Na+) to impart a strong negative zeta potential (-40 to -60 mV) across pH 1.0 to 13.0.

Supplied as a free-flowing, hygroscopic yellowish-brown spray-dried powder (dry content ~95.0% w/w, moisture <= 5.0%–7.0% w/w, 10% aqueous pH 6.5 to 8.5, bulk density 450 to 650 g/L, water solubility >= 400 to 550 g/L at 20 °C, 1% surface tension 62 to 70 mN/m, and Ross-Miles persistent foam 0 to 5 mm), Tamol PP serves as a benchmark protective-colloid emulsifier and stabilizer in synthetic rubber (SBR, NBR, CR) and resin emulsion polymerization, a neutral-pH non-foaming primary dispersant in agrochemical Wettable Powders (WP), Water Dispersible Granules (WDG / WG), and Suspension Concentrates (SC), and a high-efficiency wood-pitch and sticky-deposit passivator in pulp and paper manufacturing. Furthermore, its non-yellowing phenolic-urea backbone makes Tamol PP the preferred polyamide (nylon) stain-blocker and wool/nylon dye-reserve auxiliary in textiles, as well as a lightfast auxiliary/replacement syntan for white and pastel leathers.
