TERGITOL NP-30 SURFACTANT

This thick, hydrated polyoxyethylene steric brush gives TERGITOL NP-30 Surfactant two decisive operational advantages over lower-ethoxylation surfactants (such as NP-9 or NP-10, whose cloud points are only 54 to 63 °C and which salt out in concentrated brines or coagulate above 65 °C): first, the 1% aqueous cloud point of TERGITOL NP-30 Surfactant exceeds 100 °C, enabling it to function without phase separation in boiling textile scouring/dyeing baths (85 to 130 °C), hot emulsion polymerization reactors (75 to 95 °C), and high-temperature oilfield fluids. Second, during the emulsion polymerization of vinyl acetate, acrylates, styrene-butadiene (SBR), and vinyl chloride—or during post-polymerization latex let-down—TERGITOL NP-30 Surfactant prevents coagulum formation, eliminates divalent calcium/magnesium electrolyte shock, and imparts multi-cycle freeze-thaw stability.

Supplied commercially by Ataman Kimya with low odor, strict moisture and pH control (pH 5.5 to 7.5 in 1% aqueous solution), and non-hazardous transport status across ADR, RID, IMDG, and IATA (unlike low-EO grades NP-4 through NP-12), TERGITOL NP-30 Surfactant is an indispensable formulation tool for polymer chemists, coating engineers, and industrial formulators in permitted technical markets. Selecting the appropriate active form (100% Solid/Molten versus 70% Aqueous Liquid) and anionic/nonionic surfactant ratio for TERGITOL NP-30 Surfactant guarantees grit-free polymer dispersions, flocculation-resistant universal pigment pastes, and crystal-clear high-electrolyte detergent and agrochemical concentrates.

WHAT IS TERGITOL NP-30 SURFACTANT?

TERGITOL NP-30 Surfactant is a high-molecular-weight, nonionic alkylphenol ethoxylate (APE / NPE) surfactant produced by reacting 1 mole of branched para-nonylphenol with an average of 30 moles of ethylene oxide (EO). Within the renowned TERGITOL NP homologous surfactant series (which spans from oil-soluble, low-EO defoamers/wettants like TERGITOL NP-4 [HLB 8.9] and all-purpose detergent/wetting grades like TERGITOL NP-9 [HLB 12.9] and TERGITOL NP-10 [HLB 13.6] up to ultra-high-EO emulsion-polymerization stabilizers like TERGITOL NP-30 [HLB 17.1] and TERGITOL NP-40 [HLB 17.8]), TERGITOL NP-30 Surfactant represents the premier 30-mole ethoxylate designed specifically for aqueous systems requiring extreme hydrophilicity, boiling-water cloud point stability (> 100 °C), high electrolyte tolerance, and robust steric stabilization of polymer latices and pigment dispersions.

Because its polyoxyethylene chain contains an average of 30 repeating oxyethylene units (-(CH2CH2O)30-H, molecular weight ~1,320 g/mol attached to a 220 g/mol nonylphenol hydrophobic anchor, total MW ~1,540 g/mol), 100% active TERGITOL NP-30 Surfactant is a white waxy solid at room temperature (melting at ~40 °C into a clear low-viscosity liquid) that dissolves rapidly in cold or hot water to form crystal-clear micellar solutions.
In industrial formulation practice, TERGITOL NP-30 Surfactant is rarely used as a simple room-temperature surface-tension reducer; instead, it is engineered to solve high-stress colloidal stability problems where conventional 9-mole or 10-mole ethoxylates fail—such as stabilizing vinyl acetate, acrylic, styrene-acrylic, and SBR latex emulsions against shear coagulation, calcium/magnesium electrolyte shock, and freeze-thaw cycles, dispersing high-load organic and inorganic pigments in waterborne coatings, and emulsifying or cleaning in boiling (> 95 °C) or high-salt environments.

HISTORICAL DEVELOPMENT AND THE ROLE OF HIGH-EO NONYLPHENOL ETHOXYLATES IN POLYMER SCIENCE

Nonylphenol ethoxylates were first developed in the late 1930s and commercialized on a large scale in the 1950s (under the TERGITOL NP and Igepal CO trademarks) as synthetic petrochemical alternatives to natural soaps. As the synthetic latex industry expanded rapidly in the 1950s and 1960s—replacing solvent-borne alkyd house paints, solvent adhesives, and natural rubber latex with waterborne polyvinyl acetate (PVAc), vinyl acetate-ethylene (VAE), all-acrylic, styrene-acrylic, and styrene-butadiene (SBR) emulsions—polymer chemists discovered a fundamental limitation of anionic surfactants (like sodium lauryl sulfate SLS) and low-EO nonionics (like NP-9):
- Latices stabilized solely with anionic surfactants coagulated instantly when exposed to divalent calcium or magnesium ions in hard tap water, zinc oxide, or calcium carbonate fillers, and coagulated irreversibly when frozen during winter transport.
- Latices stabilized with 9-mole or 10-mole nonylphenol ethoxylates (NP-9 / NP-10) coagulated in the reactor during monomer polymerization at 75 to 90 °C because the reaction temperature exceeded the surfactant's cloud point (54 to 63 °C)!
Introducing 30-mole ethoxylated TERGITOL NP-30 Surfactant (HLB 17.1, Cloud Point > 100 °C) solved both challenges simultaneously: its cloud point stayed safely above the 80–95 °C polymerization temperature, and its long 30-EO hydrophilic tail formed a thick, non-ionic hydrated steric bumper around each latex particle that rendered the dispersion immune to Ca2+/Mg2+ electrolytes and freeze-thaw ice crystal compression!

CHEMICAL STRUCTURE, HLB 17.1 STERIC-BARRIER ARCHITECTURE, AND COLLOIDAL MECHANISM

The colloidal performance of TERGITOL NP-30 Surfactant is governed by four molecular and thermodynamic properties:
 Amphiphilic Anchor-Brush Geometry (C9H19-C6H4- Hydrophobe + 30-EO Hydrophile):
The hydrophobic anchor of TERGITOL NP-30 Surfactant consists of a branched C9-alkyl (nonyl) chain para-substituted onto an aromatic benzene ring (total carbon number C15, hydrophobic molecular weight 220.35 g/mol). The aromatic pi-electron cloud and branched C9 tail exhibit strong van der Waals and pi-pi adsorption affinity for hydrophobic polymer surfaces (polystyrene, polybutyl acrylate, polyvinyl acetate, PVC, SBR) and organic pigment crystals (phthalocyanine blue/green, carbon black, azo pigments). Projecting outward from the phenolic oxygen is a 30-unit polyethylene glycol chain (-(CH2CH2O)30-H) that binds 2 to 3 water molecules per ether oxygen via hydrogen bonding, creating an extended hydrated hydrodynamic layer (~4 to 6 nm thick) around the particle.

 Entropic and Osmotic Steric Stabilization (DLVO + Steric Theory):
When two latex particles or pigment crystals coated with TERGITOL NP-30 Surfactant approach each other to within twice the thickness of the adsorbed 30-EO brush layer (< 8–12 nm) due to Brownian motion, high-shear pumping, or ice-crystal growth during freezing, the hydrated 30-EO chains are forced to interpenetrate and compress. This compression causes two powerful repulsive effects:
- Osmotic Repulsion ( Enthalpic Mixing Term): The local concentration of polyoxyethylene segments in the overlap zone spikes, driving water molecules osmotically into the gap to push the particles apart.
- Entropic Elastic Repulsion (Volume Restriction Term): Compressing the 30-EO chains restricts their conformational freedom (lowering configurational entropy delta S), creating an elastic spring-like repulsive force that prevents the particles from ever reaching the primary van der Waals attraction minimum where irreversible coagulation occurs!

 Ultra-High Cloud Point (> 100 °C in Water; ~74 °C in 10% NaCl Brine):
In nonionic ethoxylates, the cloud point is the temperature at which thermal agitation breaks hydrogen bonds between ether oxygens and water, causing the surfactant to dehydrate and phase-separate. Because TERGITOL NP-30 Surfactant carries 30 ethylene oxide units (85.7% EO by weight), its hydration energy is so high that a 1% solution in pure water remains 100% clear even at the boiling point (> 100 °C). Even in concentrated electrolyte solutions (such as 10% w/w NaCl or 5% Na2SO4) that "salt out" NP-9 at room temperature, TERGITOL NP-30 Surfactant remains completely soluble up to 70–76 °C!

 Synergistic Mixed-Micelle Formation with Anionic Surfactants:
In emulsion polymerization and heavy-duty detergents, TERGITOL NP-30 Surfactant is frequently paired in a 3:1 to 1:1 weight ratio with an anionic surfactant (such as Sodium Lauryl Ether Sulfate SLES, Sodium Lauryl Sulfate SLS, or Sodium Dodecylbenzenesulfonate SDBS). The 30-EO chains shield the negatively charged sulfate/sulfonate headgroups from electrostatic self-repulsion, lowering the mixed Critical Micelle Concentration (CMC) and combining fast anionic monomer nucleation with long-term nonionic steric and electrolyte stability.

INDUSTRIAL PRODUCTION AND MANUFACTURING PROCESSES

Commercial TERGITOL NP-30 Surfactant supplied by Ataman Kimya is manufactured via controlled alkoxylation in pressurized stainless-steel loop or stirred-tank reactors:
- Stage 1 (Synthesis of Branched 4-Nonylphenol Feedstock):
  Phenol is alkylated catalytically with propylene trimer (branched nonene, C9H18) over an acidic ion-exchange resin or solid acid catalyst to produce high-purity para-branched 4-nonylphenol (CAS 84852-15-3, >= 90%–95% para-isomer, distilled to water-white clarity).
- Stage 2 (Base-Catalyzed High-Molar Ethoxylation with 30 Moles of Ethylene Oxide):
  Molten 4-nonylphenol and an alkaline alkoxylation catalyst (typically 0.1% to 0.3% w/w potassium hydroxide KOH or sodium methoxide CH3ONa) are charged into a pressure reactor and vacuum-dehydrated at 110 °C to moisture < 0.05% (preventing the formation of free polyethylene glycol PEG diol byproduct). After purging thoroughly with dry nitrogen to oxygen < 10 ppm, 30.0 molar equivalents of liquid Ethylene Oxide (EO, CAS 75-21-8) are metered gradually into the circulating reaction mass at 135 to 165 °C and 3 to 6 bar pressure:
  C9H19-C6H4-OH + 30 CH2(-O-)CH2 (Ethylene Oxide)  --[KOH, 150 °C]-->  C9H19-C6H4-O-(CH2CH2O)30-H (TERGITOL NP-30)
- Stage 3 (Digestion, Vacuum Stripping of Trace EO / 1,4-Dioxane, and Neutralization):
  After EO addition is completed, the batch is digested at 150 °C until residual pressure drops to baseline, then vacuum-stripped with nitrogen/steam to reduce free ethylene oxide below 1 ppm and trace 1,4-dioxane to minimal levels. The alkaline catalyst is neutralized with glacial acetic acid, lactic acid, or phosphoric acid to yield a 1% aqueous pH of 5.5 to 7.5, and bleached with a trace of hydrogen peroxide if required to guarantee molten color <= 50–100 APHA.
- Stage 4 (Flaking, Solid Cast Drumming, or 70% Aqueous Dilution):
  The molten 100% active TERGITOL NP-30 Surfactant (at 55–65 °C) is either filled directly into 200–210 kg open-head or tight-head drums (where it solidifies into a white waxy solid below 40 °C), chilled on a rotating flaker drum to produce free-flowing waxy flakes/pastilles in 25 kg bags, or blended with 30.0% w/w deionized water to produce pumpable liquid TERGITOL NP-30 (70% Aq).

WHY EACH IMPORTANT PROPERTY OF TERGITOL NP-30 SURFACTANT MATTERS IN PRACTICE

 HLB Value of 17.1 and 30-Mole EO Chain Length:
In emulsion polymerization and pigment dispersion, surfactants with HLB 12 to 14 (such as NP-9 or NP-10) have short 9- to 10-unit EO chains (~1.5 nm thick) that cannot prevent latex particles from colliding and coagulating when high levels of Ca2+ electrolyte or high mechanical shear are applied. The 30-unit EO chain of TERGITOL NP-30 Surfactant (HLB 17.1) creates a thick (~5 nm), strongly hydrated steric shield that keeps polymer particles dispersed even when mixed with cement, calcium carbonate fillers, or multivalent metal salts.

 Cloud Point > 100 °C in Water:
When emulsion polymerization of styrene-acrylic, pure acrylic, or VAE copolymers is conducted at 75 to 90 °C (or during steam stripping of residual monomers at 95 °C), surfactants with cloud points below 75 °C dehydrate, oil out of the water phase, and cause massive reactor wall fouling and coagulum ("grit"). Because the cloud point of TERGITOL NP-30 Surfactant exceeds 100 °C, it stays 100% hydrated and active throughout the hottest polymerization and steam-stripping cycles!
 
 Solid Waxy Form at Room Temperature (Melting Point ~40 °C) and Water-Dissolving Flexibility:
Because 100% active TERGITOL NP-30 Surfactant melts at ~40 °C, it can be used in both dry powder blends (such as wettable powders WP, water-dispersible granules WDG, or dry detergent powders when flaked) and liquid formulations (either by melting drums at 50–55 °C, dissolving flakes in warm 45–60 °C water, or purchasing the pre-diluted 70% active aqueous liquid grade).

HOW DOES TERGITOL NP-30 SURFACTANT WORK AT THE MOLECULAR AND PROCESS LEVEL?

 Dual-Surfactant Emulsion Polymerization Control (Anionic Nucleation + Nonionic Steric Growth):
In industrial semi-continuous emulsion polymerization of acrylic esters (butyl acrylate, methyl methacrylate, 2-ethylhexyl acrylate), styrene, vinyl acetate, or vinyl chloride, formulators combine a small amount of anionic surfactant (0.2% to 0.8% w/w SLS, SLES, or SDBS on monomer) with 1.0% to 3.0% w/w TERGITOL NP-30 Surfactant:
- In Stage 1 (Micellar Nucleation): The anionic surfactant controls the number of primary micelles and sets the fine target latex particle size (typically 100 to 250 nm).
- In Stage 2 (Particle Growth at 75–90 °C) & Stage 3 (Post-Stabilization): As monomer droplets feed in and latex particle surface area expands rapidly, TERGITOL NP-30 Surfactant adsorbs densely onto the growing polymer spheres. Its 30-EO chains prevent thermal coagulation during the 85 °C reaction exotherm and post-reaction steam stripping, and allow the finished latex to survive 5+ freeze-thaw cycles (-15 °C / +23 °C) and high-shear pumping without flocculation.

 Steric Stabilization of Organic and Inorganic Pigments in Waterborne Coatings:
Organic pigments (such as Phthalocyanine Blue PB15:3, Phthalocyanine Green PG7, Diarylide Yellow, and Quinacridone Red) and Carbon Black have hydrophobic, low-polarity crystal surfaces that agglomerate in waterborne paints. When milled with 2% to 10% w/w TERGITOL NP-30 Surfactant (often paired with an anionic polycarboxylate or naphthalene sulfonate dispersant), the nonylphenol aromatic ring adsorbs flat onto the hydrophobic pigment crystal via pi-pi stacking while the 30-EO tail stabilizes the dispersed pigment in aqueous tinting pastes—eliminating color rub-up ("flooding and floating") when mixed into white base paints.

 High-Electrolyte and High-Temperature Detergency & Acidizing Compatibility:
In concentrated acid metal pickling baths (10%–20% HCl or H2SO4), oilfield well-acidizing fluids, and boiling alkaline textile kier-boiling baths (2%–5% NaOH at 95–130 °C), ionic surfactants precipitate or decompose and low-EO nonionics salt out. TERGITOL NP-30 Surfactant remains chemically intact and soluble across pH 1 to 13 and high salt ionic strengths, lowering interfacial tension and suspending emulsified oils and waxes cleanly.

WHAT PROBLEMS CAN TERGITOL NP-30 SURFACTANT HELP SOLVE?

 Eliminating Reactor Coagulum ("Grit") and Wall Fouling in High-Temperature Emulsion Polymerization: Replacing lower-cloud-point ethoxylates with TERGITOL NP-30 Surfactant (cloud point > 100 °C) prevents surfactant dehydration during 80–95 °C monomer polymerization and steam stripping, slashing filter-bag waste and reactor cleaning downtime.
 Solving Freeze-Thaw Coagulation and Calcium/Cement Shock in Polymer Latices: Post-adding 0.5% to 2.0% w/w TERGITOL NP-30 Surfactant to PVAc, VAE, SBR, or acrylic dispersions provides a thick 30-EO steric barrier that prevents latex gelation when frozen in winter transit or when blended with Portland cement, gypsum, or CaCO3 fillers in construction adhesives and mortars.
 Preventing Surfactant "Salting Out" in High-Electrolyte Cleaners and Agrochemical Concentrates: In concentrated salt solutions (such as glyphosate/glufosinate salts, liquid fertilizers, alkaline builders, or oilfield brines), TERGITOL NP-30 Surfactant stays dissolved where NP-9 or C12–15 alcohol ethoxylates (7–9 EO) separate into a floating oil layer.
 Eliminating Pigment Flocculation and Color Float in Waterborne Paints & Inks: Incorporating 0.5% to 2.5% w/w TERGITOL NP-30 Surfactant into universal colorants and architectural emulsions stabilizes hydrophobic organic pigments against electrolyte shock and improves brush/roller color uniformity.
 Providing Low-Odor, Non-Flammable, Peroxide-Stable Wetting in Textile Bleaching & Dyeing: Because TERGITOL NP-30 Surfactant is resistant to hydrogen peroxide (H2O2), sodium hydrosulfite, and caustic soda at 95–130 °C, it acts as an effective high-temperature scouring penetrant and disperse/vat dye leveling auxiliary without clouding out in the dyebath.

BENEFITS FOR THE MANUFACTURER AND END USER

- Ultra-High Cloud Point (> 100 °C) and Electrolyte Resistance: Operates reliably in boiling aqueous processes and concentrated salt/acid/alkali media where standard nonionics fail.
- Powerful 30-EO Steric Stabilization (HLB 17.1): Protects polymer latices, asphalt emulsions, and pigment pastes against mechanical shear, multivalent cations (Ca2+, Mg2+, Al3+, Fe3+), and freeze-thaw cycles.
- Broad Chemical Stability Across pH 1 to 13: Chemically stable in the presence of dilute and moderately concentrated mineral acids, caustic alkalies, hard-water salts, and hydrogen peroxide oxidizing baths.
- Versatile Compatibility: Fully compatible with anionic, cationic, amphoteric, and other nonionic surfactants, water-soluble polymers (PVA, HEC, xanthan), and polar organic solvents.
- Non-Regulated Transport Status (Unlike Low-EO NPEs): Whereas liquid low-EO nonylphenol ethoxylates (NP-4 to NP-12) are often classified as Class 9 Marine Pollutants (UN 3082) due to lower aquatic LC50 values, high-molecular-weight 30-mole TERGITOL NP-30 Surfactant (MW ~1,540 g/mol) exhibits much lower aquatic toxicity and is NOT classified as dangerous goods for road, sea, or air transport.

- Emulsion Polymerization and Post-Polymerization Latex Stabilization with TERGITOL NP-30 Surfactant: In the semi-batch emulsion polymerization of butyl acrylate / methyl methacrylate (BA/MMA), styrene / butyl acrylate (S/BA), vinyl acetate / VeoVa, or vinyl acetate / ethylene (VAE) at 75 to 90 °C, TERGITOL NP-30 Surfactant is typically dosed at 1.0% to 3.0% w/w based on total monomer weight, dissolved in the aqueous monomer pre-emulsion feed alongside 0.2% to 0.6% w/w of an anionic surfactant (such as SLS, SLES, or SDBS). During the polymerization reaction and subsequent 90 °C redox chasing / steam stripping, TERGITOL NP-30 Surfactant keeps coagulum ("grit" retained on a 100-mesh screen) below 0.02% w/w. In addition, post-adding 0.5% to 1.5% w/w TERGITOL NP-30 Surfactant (as a 25%–70% aqueous solution) during latex cool-down dramatically boosts divalent CaCl2 electrolyte stability and allows the finished latex or waterborne adhesive to pass 5 freeze-thaw cycles (-15 °C / +23 °C).
- Paints, Coatings, and Universal Pigment Concentrates with TERGITOL NP-30 Surfactant: In aqueous architectural interior/exterior paints and high-solids pigment dispersions, adding 0.5% to 2.0% w/w TERGITOL NP-30 Surfactant into the millbase or let-down improves pigment wetting, prevents flocculation shock when tinting high-PVC (Pigment Volume Concentration) calcium-carbonate-filled flat paints with organic phthalocyanine or iron oxide colorants, and extends wet-edge open time.

USE OF TERGITOL NP-30 SURFACTANT IN AGROCHEMICALS, TEXTILE PROCESSING, OILFIELD FLUIDS AND INDUSTRIAL CLEANERS

- Agrochemical SC, EW, SE, and WDG Formulations with TERGITOL NP-30 Surfactant: In pesticide Suspension Concentrates (SC) and Suspo-Emulsions (SE), 1.5% to 4.0% w/w TERGITOL NP-30 Surfactant (paired with calcium dodecylbenzenesulfonate or naphthalene sulfonate condensates) provides steric stabilization that prevents Ostwald crystal growth and phase separation during 54 °C accelerated storage. Because 100% active TERGITOL NP-30 Surfactant is a waxy solid (mp 40 °C), it can also be melted or sprayed onto silica/clay carriers in Wettable Powders (WP) and Water-Dispersible Granules (WDG) at 2% to 6% w/w.
- High-Temperature Textile Scouring, Dyeing, and Oilfield Brines with TERGITOL NP-30 Surfactant: In 130 °C pressure-jet polyester dyeing and 95 °C alkaline cotton scouring/peroxide bleaching, dosing 0.5 to 2.5 g/L TERGITOL NP-30 Surfactant prevents dye agglomeration and wax redeposition without clouding out. In oilfield 15% HCl limestone acidizing fluids and high-density CaCl2/NaBr completion brines, 0.2% to 1.5% w/w TERGITOL NP-30 Surfactant functions as a non-precipitating water-wetting and sludge-preventing surfactant.

FORMULATION AND PROCESS CONSIDERATIONS WHEN USING TERGITOL NP-30 SURFACTANT

 Melting, Dissolving, and Avoiding the "Gel Phase" When Diluting 100% Active TERGITOL NP-30 Surfactant:
Because 100% active TERGITOL NP-30 Surfactant is a solid waxy material at room temperature (pour/melting point ~40 °C):
- Drum Melting Protocol: To liquefy a 200 kg drum of 100% active TERGITOL NP-30 Surfactant, place the drum in a hot-air warming oven or steam chest at 50 to 60 °C (or use low-watt-density warm-water coils; avoid localized overheating above 85 °C in air to prevent oxidative yellowing). At 50–60 °C, TERGITOL NP-30 Surfactant is a clear, low-viscosity liquid (~43 to 72 mPa·s) that pumps and meters effortlessly.
- Aqueous Dilution Protocol (Preventing Liquid-Crystalline Gel Lumps): Like all high-EO nonionic surfactants, when 100% active TERGITOL NP-30 Surfactant is mixed with cold water at concentrations between ~35% and 60% w/w, it can pass through a transient, viscous hexagonal liquid-crystalline gel phase. To dissolve 100% active TERGITOL NP-30 Surfactant rapidly without gel lumps, always add the molten or flaked surfactant into agitated warm water heated to 50 to 70 °C (never dump cold water on top of a block of solid surfactant!). Alternatively, prepare or purchase a 25%–30% or 70% w/w aqueous stock solution (at 70% w/w in water, TERGITOL NP-30 forms a pumpable isotropic liquid above 4 °C).

 Pairing with Lower-HLB Surfactants to Tune Required HLB in Oil-in-Water Emulsions:
On its own, TERGITOL NP-30 Surfactant has a very high HLB of 17.1—meaning its small nonylphenol tail and massive 30-EO head are too hydrophilic to emulsify non-polar paraffinic mineral oils (required HLB ~ 10 to 12) when used alone. However, when blended at a 30:70 to 50:50 ratio with a low-HLB co-emulsifier such as TERGITOL NP-4 (HLB 8.9), TERGITOL NP-6 (HLB 10.9), or Sorbitan Monooleate (Span 80, HLB 4.3), the low-HLB surfactant packs tightly at the oil-water interface while the 30-EO chains of TERGITOL NP-30 Surfactant extend into the water phase—producing ultra-fine, heat- and salt-stable oil-in-water emulsions!

TYPICAL USE LEVELS AND INITIAL FORMULATION APPROACHES FOR TERGITOL NP-30 SURFACTANT

Typical commercial incorporation levels for TERGITOL NP-30 Surfactant (calculated on a 100% active basis) depend on the colloidal system:
- Emulsion Polymerization of Acrylic, Styrene-Acrylic, PVAc, and VAE Latices (Primary Emulsifier): TERGITOL NP-30 Surfactant is dosed at 1.0% to 3.5% w/w based on total monomer weight (typically 1.5% to 2.5% w/w, paired with 0.2% to 0.6% w/w anionic SLS, SLES, or SDBS surfactant).
- Post-Polymerization Latex Stabilization (Freeze-Thaw & Ca2+/Cement Stability Booster): TERGITOL NP-30 Surfactant is added post-reaction at 0.5% to 2.0% w/w on latex solids.
- Waterborne Architectural Paints, Coatings, and Universal Pigment Concentrates: TERGITOL NP-30 Surfactant is incorporated at 0.3% to 1.5% w/w in finished paints and 2.0% to 8.0% w/w in high-solids organic/inorganic pigment dispersions.
- Agrochemical Suspension Concentrates (SC), Emulsions in Water (EW), and WDG/WP Formulations: TERGITOL NP-30 Surfactant is dosed at 1.5% to 5.0% w/w of total formulation weight.
- High-Temperature Textile Scouring, Peroxide Bleaching, and HTHP Dyeing Baths: TERGITOL NP-30 Surfactant is used at 0.5 to 3.0 g/L (0.05% to 0.30% w/w) in the processing liquor.
- Heavy-Duty High-Electrolyte Alkaline/Acid Cleaners and Oilfield Stimulation Fluids: TERGITOL NP-30 Surfactant is added at 0.5% to 4.0% w/w.
The four laboratory and pilot frameworks below illustrate preliminary R&D evaluation protocols for qualified technical personnel formulating with TERGITOL NP-30 Surfactant.

EXAMPLE 1: SEMI-CONTINUOUS EMULSION POLYMERIZATION OF A 50% SOLIDS STYRENE-ACRYLIC LATEX STABILIZED WITH TERGITOL NP-30 SURFACTANT

Purpose: To synthesize a 50% non-volatile solids Styrene / n-Butyl Acrylate / Acrylic Acid (S/BA/AA) copolymer emulsion at 82 °C using a synergistic TERGITOL NP-30 Surfactant + Sodium Lauryl Sulfate (SLS) emulsifier system, and evaluate reactor coagulum (100-mesh grit), particle size, divalent CaCl2 electrolyte tolerance, and 5-cycle freeze-thaw stability.
Initial reactor recipe (per 1,000.0 g finished latex batch, ~50.0% solids, MFFT ~18 °C):

  - Deionized Water: 225.0 g
  - TERGITOL NP-30 Surfactant (100% Active Grade, pre-dissolved in warm 55 °C water): 9.5 g (1.90% w/w on monomer; Total TERGITOL NP-30 = 11.0 g = 2.20% w/w on monomer)
  - Sodium Lauryl Sulfate (SLS, 30% aqueous solution): 5.0 g (delivering 1.50 g = 0.30% active SLS on monomer; Total active SLS = 0.48% w/w on monomer)
  - Styrene Monomer (SM): 240.0 g (48.0% of monomer mix)
  - n-Butyl Acrylate Monomer (BA): 250.0 g (50.0% of monomer mix)
  - Glacial Acrylic Acid (AA, carboxylated shell monomer for mechanical/freeze-thaw stability): 10.0 g (2.0% of monomer mix; Total Monomers = 500.0 g)
- Initiator & Neutralizer Solutions:
  - Ammonium Persulfate (APS, 2.2 g dissolved in 30.0 g deionized water): 32.2 g
  - Aqueous Ammonia (25% NH3, added post-polymerization at 40 °C to adjust pH to 8.0–8.5): ~3.0 g
Laboratory evaluation procedure:
- Stage 1 (Pre-Emulsion Preparation & Seed Nucleation): Dissolve the 9.5 g TERGITOL NP-30 Surfactant and 5.0 g SLS (30%) in the 225.0 g warm deionized water, cool to 28 °C, and emulsify the 240.0 g Styrene, 250.0 g Butyl Acrylate, and 10.0 g Acrylic Acid under medium agitation to form a stable creamy monomer pre-emulsion. Charge the Initial Kettle Charge into a 2-liter jacketed glass reactor under a nitrogen blanket, heat to 80 °C, add 25% of the APS initiator solution and 5% of the monomer pre-emulsion, and hold at 80–82 °C for 15 minutes to generate a blue-sheen primary latex seed.
- Stage 2 (Semi-Continuous Feed at 82 °C): Meter the remaining 95% of the monomer pre-emulsion and 75% of the APS initiator solution concurrently into the reactor over 3.5 hours while maintaining reactor temperature strictly at 82 +/- 1 °C. Because the cloud point of TERGITOL NP-30 Surfactant exceeds 100 °C, zero surfactant dehydration or reactor wall fouling occurs at 82 °C!
- Stage 3 (Post-Cook, Neutralization, and Colloidal Stability Testing): Hold at 85 °C for 45 minutes to complete monomer conversion (> 99.8%), cool to 40 °C, neutralize to pH 8.2 with aqueous ammonia, and filter through a 150-micron (100-mesh) stainless-steel screen. Verify: wet coagulum ("grit") on 100-mesh screen <= 0.015% w/w, non-volatile solids = 50.0 +/- 0.5%, mean laser-diffraction particle size = 145 to 175 nm, Brookfield LV viscosity (60 rpm) = 350 to 650 mPa·s, complete stability when mixed 1:1 with 10% w/w aqueous CaCl2 solution for 24 hours (confirming multivalent electrolyte immunity), and zero coagulation or viscosity jump after 5 freeze-thaw cycles (-15 °C for 16 h / +23 °C for 8 h, ASTM D2243).

EXAMPLE 2: HIGH-SOLIDS ORGANIC PHTHALOCYANINE BLUE UNIVERSAL PIGMENT PASTE STABILIZED WITH TERGITOL NP-30 SURFACTANT

Purpose: To formulate a 42% pigment-loaded, resin-free aqueous Phthalocyanine Blue (PB 15:3) universal tinting concentrate using TERGITOL NP-30 Surfactant as the primary steric nonionic dispersant, and evaluate bead-mill viscosity, tinting strength, and zero color float ("rub-up") in architectural latex paints.
Initial pigment dispersion formulation (per 1,000.0 g batch):
- Deionized Water: 410.0 g (41.0% w/w)
- Propylene Glycol (humectant / open-time retarder to prevent nozzle crusting): 80.0 g (8.0% w/w)
- TERGITOL NP-30 Surfactant (CAS 127087-87-0, Ataman Kimya 100% Active Grade, HLB 17.1, pre-melted at 50 °C, primary steric pigment dispersant and paint compatibilizer): 55.0 g (5.5% w/w; 13.1% on pigment weight)
- Sodium Salt of Naphthalene Sulfonate Condensate or Acrylic Co-Dispersant (40% active electrostatic co-dispersant): 30.0 g (3.0% w/w)
- Non-Silicone Mineral-Oil / Acetylenic Defoamer: 3.5 g (0.35% w/w)
- 1,2-Benzisothiazolin-3-one (BIT, 20% biocide): 1.5 g (0.15% w/w)
- Copper Phthalocyanine Blue Beta-Form Dry Pigment Powder (Pigment Blue 15:3, high surface area ~55 m2/g): 420.0 g (42.0% w/w)
Laboratory evaluation procedure:
- Dissolve the 55.0 g molten TERGITOL NP-30 Surfactant, 30.0 g anionic co-dispersant, 80.0 g propylene glycol, 2.0 g defoamer, and 1.5 g biocide in the 410.0 g warm deionized water (45 °C) under propeller agitation until clear, then cool to 25 °C.
- Slowly charge the 420.0 g Phthalocyanine Blue 15:3 powder under a high-shear sawtooth cowles dissolver (4,000 rpm for 20 minutes) to wet out the pigment agglomerates.
- Recirculate the pre-dispersion through a horizontal zirconia bead mill (0.8 mm YSZ beads, chamber cooled < 35 °C) until Hegman fineness of grind is >= 7.5 (< 5 microns) and d90 < 350 nm, then blend in the remaining 1.5 g defoamer.
- Verify Brookfield Stormer viscosity (62 to 72 KU), < 5% viscosity drift after 14 days at 50 °C, and tint 2.0% w/w of the blue paste into both a high-gloss acrylic enamel and a 70%-PVC calcium-carbonate flat wall paint: perform the finger "rub-up" test on drying drawdowns and confirm delta E color difference between sprayed/brushed and rubbed zones is <= 0.30 (confirming zero pigment flocculation thanks to the 30-EO steric barrier of TERGITOL NP-30 Surfactant).

EXAMPLE 3: CEMENT-COMPATIBLE SBR / VAE LATEX MORTAR MODIFIER POST-STABILIZATION WITH TERGITOL NP-30 SURFACTANT

Purpose: To evaluate how post-adding 1.5% w/w TERGITOL NP-30 Surfactant to a carboxylated Styrene-Butadiene Rubber (X-SBR) latex prevents instantaneous coagulation when mixed with alkaline Portland cement (pH 12.8, saturated Ca(OH)2 / Ca2+ ions) in a polymer-modified tile adhesive or repair mortar.
Initial cement-latex mortar evaluation recipe (Water/Cement ratio = 0.40, Polymer/Cement ratio = 0.10):
- Carboxylated SBR Latex (50.0% solids, pH 8.0, un-post-stabilized base latex): 200.0 g (delivering 100.0 g dry SBR polymer)
- TERGITOL NP-30 Surfactant (prepared as a 30.0% w/w aqueous stock solution from Ataman Kimya 100% Active Grade; dosed at 1.5% active TERGITOL NP-30 on dry SBR weight): 5.0 g of 30% solution (delivering 1.50 g active TERGITOL NP-30)
- Silicone/Mineral Oil Powder Antifoam: 1.0 g
- Ordinary Portland Cement (CEM I 42.5 R, rich in soluble Ca2+, SO4^2-, K+, Na+ ions at pH ~12.8): 1,000.0 g
- Graded Quartz Silica Sand (0.1 to 0.5 mm): 2,000.0 g
- Additional Mixing Water (to reach total water = 400.0 g including latex water): 296.5 g
Laboratory evaluation procedure:
- Stir the 5.0 g of 30% aqueous TERGITOL NP-30 Surfactant solution and 1.0 g antifoam into the 200.0 g X-SBR latex for 20 minutes at 23 °C, allowing the nonylphenol tails of TERGITOL NP-30 Surfactant to adsorb onto the SBR latex spheres.
- Blend the modified latex with the 296.5 g mixing water, then add the 1,000.0 g Portland cement and 2,000.0 g silica sand in a planetary mortar mixer (EN 196-1) at low speed for 60 seconds and high speed for 120 seconds.
- Compare against an unmodified X-SBR latex control (0.0% TERGITOL NP-30): whereas the unmodified SBR latex coagulates into rubbery crumbs within 30 seconds due to multivalent Ca2+ / Al3+ bridging of its carboxylate groups, the batch stabilized with 1.5% TERGITOL NP-30 Surfactant forms a smooth, buttery, self-leveling mortar with slump flow >= 175 mm, pot life >= 90 minutes, and 28-day flexural strength >= 8.5 MPa!

EXAMPLE 4: HIGH-ELECTROLYTE ALKALINE METAL DEGREASER AND HIGH-TEMPERATURE TEXTILE SCOURING CONCENTRATE

Purpose: To formulate a crystal-clear, high-caustic/high-builder liquid alkaline cleaner and textile scouring concentrate that remains single-phase up to 85 °C without salting out, utilizing TERGITOL NP-30 Surfactant as a high-cloud-point co-surfactant and hydrotrope stabilizer.
Initial high-electrolyte cleaner concentrate (per 1,000.0 g batch):
- Deionized Water: 695.0 g (69.5% w/w)
- Potassium Hydroxide (KOH, 50% liquid) + Tetrapotassium Pyrophosphate (TKPP, anhydrous electrolyte builder): 80.0 g KOH (50%) + 100.0 g TKPP (total 14.0% w/w strong electrolyte/alkali solids)
- Sodium Metasilicate Pentahydrate (corrosion inhibitor / alkaline builder): 30.0 g (3.0% w/w)
- Low-EO Wetting Surfactant (TERGITOL NP-9 or C9–11 Alcohol 6 EO, HLB ~12.8, fast oil-penetrating surfactant that normally salts out in 14% KOH/TKPP!): 35.0 g (3.5% w/w)
- TERGITOL NP-30 Surfactant (CAS 127087-87-0, Ataman Kimya 100% Active Grade, HLB 17.1, Cloud Point > 100 °C, high-electrolyte micellar solubilizer and high-temperature wetting stabilizer): 40.0 g (4.0% w/w)
- Sodium Cumenesulfonate (40% aqueous hydrotrope co-coupling aid): 20.0 g (2.0% w/w)
Laboratory evaluation procedure:
- Dissolve the 100.0 g TKPP, 30.0 g sodium metasilicate, and 80.0 g KOH (50%) in the 695.0 g deionized water (exothermic dissolution warms the solution to ~50 °C).
- At 50 °C, add the 40.0 g TERGITOL NP-30 Surfactant, 35.0 g NP-9/alcohol ethoxylate, and 20.0 g sodium cumenesulfonate and stir for 20 minutes until crystal clear.
- Verify that without TERGITOL NP-30 Surfactant, the 3.5% NP-9 oils out immediately into a brown top layer at 25 °C due to the high ionic strength of the 10% TKPP + 4% KOH solution; with 4.0% TERGITOL NP-30 Surfactant forming mixed micelles, the concentrate remains a crystal-clear, single-phase liquid from 0 °C up to a cloud point of 78 °C, and when diluted 1:20 in water at 90 °C, cleans rolling oils from steel panels and waxes from raw cotton fabric with zero clouding!

COMPATIBILITY AND INCOMPATIBILITY OF TERGITOL NP-30 SURFACTANT

- Broad Chemical & Formulation Compatibility:
  - Surfactants & Polymers: Because TERGITOL NP-30 Surfactant is nonionic (uncharged), it is 100% compatible with anionic surfactants (SLS, SLES, SDBS, dioctyl sulfosuccinate DOSS, phosphate esters, naphthalene sulfonates), cationic surfactants (quaternary ammonium biocides and fabric softeners), amphoteric surfactants (betaines, amine oxides), and water-soluble hydrocolloids (polyvinyl alcohol PVA, hydroxyethyl cellulose HEC, xanthan gum, polyacrylates).
  - Electrolytes, Hard Water, Acids & Alkalies: Exhibits extraordinary tolerance to hard water (> 1,000 ppm CaCO3), multivalent metal cations (Ca2+, Mg2+, Zn2+, Al3+, Fe3+), dilute and moderately concentrated mineral acids (HCl, H2SO4, H3PO4), caustic alkalies (NaOH, KOH, NH4OH), hydrogen peroxide (H2O2) bleaching baths, and sodium hydrosulfite reducing baths.
- Chemical Incompatibilities:
  - Strong Concentrating Oxidizing Acids & Halogens: Incompatible with concentrated nitric acid, concentrated perchloric acid, liquid bromine/chlorine, and strong dehydrating agents (concentrated 98% H2SO4 at elevated temperatures char-oxidizes the polyoxyethylene chain).
  - Phenolic Disinfectants / Parabens / Tannins at High Ratios: Like all polyoxyethylene nonionics, high ratios of TERGITOL NP-30 Surfactant can hydrogen-bond via its ether oxygens with phenolic biocides or tannins, partially reducing phenolic antimicrobial activity unless dosed appropriately.

SIMILAR PRODUCTS AND ALTERNATIVES TO TERGITOL NP-30 SURFACTANT

Formulators select between TERGITOL NP-30 Surfactant and four related surfactants based on HLB, cloud point, and regional regulatory requirements.

TERGITOL NP-30 SURFACTANT AND TERGITOL NP-9 / NP-10 (9 TO 10 MOLES EO, HLB 12.9–13.6)

TERGITOL NP-9 (HLB 12.9, cloud point 54 °C) and TERGITOL NP-10 (HLB 13.6, cloud point 63 °C) are liquid general-purpose wetting and detergency surfactants at room temperature. However, NP-9 and NP-10 dehydrate and oil out above 55–63 °C (causing reactor coagulation in 80 °C emulsion polymerizations) and salt out in concentrated electrolyte solutions. TERGITOL NP-30 Surfactant (30 moles EO, HLB 17.1, cloud point > 100 °C) provides the long steric polyoxyethylene chain needed for hot emulsion polymerization, freeze-thaw latex stabilization, and boiling or high-salt baths.

TERGITOL NP-30 SURFACTANT AND TERGITOL NP-40 (40 MOLES EO, HLB 17.8)

TERGITOL NP-40 (40 moles EO, MW ~1,980 g/mol, HLB 17.8, melting point ~48 °C) is the slightly higher-ethoxylation sibling of TERGITOL NP-30 Surfactant. While both have cloud points > 100 °C and function as latex stabilizers, TERGITOL NP-30 Surfactant (30 EO, HLB 17.1, mp 40 °C) has a slightly higher hydrophobic anchor-to-EO ratio per gram—giving TERGITOL NP-30 Surfactant stronger adsorption onto hydrophobic styrene/acrylic latex particles and pigment surfaces, a lower melting point (40 °C versus 48 °C), and lower molten viscosity.

TERGITOL NP-30 SURFACTANT AND OCTYLPHENOL ETHOXYLATE 30 EO (TRITON X-305, CAS 9002-93-1)

Triton X-305 (Octoxynol-30, 30-mole ethoxylate of branched octylphenol, typically supplied at 70% active in water, HLB 17.3) contains a C8-alkylphenol tail rather than the C9-nonylphenol tail of TERGITOL NP-30 Surfactant. Both exhibit virtually identical > 100 °C cloud points and emulsion-polymerization stabilizing behavior, with TERGITOL NP-30 Surfactant offering a more hydrophobic C9 anchor and significantly lower raw-material cost.

TERGITOL NP-30 SURFACTANT AND ALKYLPHENOL-FREE (APE-FREE) HIGH-EO ALCOHOL ETHOXYLATES (TERGITOL 15-S-30 / FATTY ALCOHOL 30 EO)

For formulations destined for the European Union or eco-labeled markets where nonylphenol ethoxylates (NPEs) are restricted under EU REACH Annex XVII Entry 46/46a, secondary alcohol ethoxylates (such as TERGITOL 15-S-30, HLB 17.4, CAS 84133-50-6) or linear/branched C12–C18 fatty alcohol 25–30 EO ethoxylates (CAS 68439-49-6 / 68920-66-1) serve as readily biodegradable APE-free replacements. However, in permitted industrial, export, and non-EU technical markets, TERGITOL NP-30 Surfactant remains widely preferred because its aromatic benzene ring provides superior pi-pi adsorption onto aromatic polymers (SBR, styrene-acrylics) and organic pigments without desorption under high shear.

QUALITY GRADES, QUALITY CONTROL AND PURCHASING CRITERIA FOR TERGITOL NP-30 SURFACTANT

Ataman Kimya supplies TERGITOL NP-30 Surfactant in two commercial physical forms to match plant handling equipment:

FIRST AID MEASURES AND SAFETY INFORMATION FOR TERGITOL NP-30 SURFACTANT

- Toxicological and Workplace Safety Profile:
  - Because of its high molecular weight (~1,540 g/mol) and long 30-unit hydrophilic polyoxyethylene chain, TERGITOL NP-30 Surfactant exhibits significantly lower acute oral Toxicity and lower skin/eye irritation than low-EO nonylphenol ethoxylates (like NP-6 or NP-9): Rat Acute Oral LD50 > 2,000 to 5,000 mg/kg bw; Rabbit Acute Dermal LD50 > 2,000 to 4,000 mg/kg bw.
  - Skin and Eye Contact: Direct contact with molten or concentrated TERGITOL NP-30 Surfactant may cause mild eye irritation (redness, watering) and mild skin dryness upon prolonged contact; hot molten liquid (> 50 °C) can cause thermal skin burns. Non-sensitizing to skin in guinea pig assays.
  - Inhalation: Extremely low vapor pressure (< 0.01 hPa at 20 °C); presents no vapor inhalation hazard at ambient temperatures, though inhalation of hot mists or aerosols generated above 70 °C should be avoided.

- Environmental Fate and Regional Regulatory Status (EU REACH / US EPA / Global):
  - Aquatic Toxicity of 30-EO Polymer vs. Degradation Metabolites: Intact 30-mole TERGITOL NP-30 Surfactant has low acute aquatic toxicity (Fish 96-h LC50 ~ 50 to > 100 mg/L; Daphnia 48-h EC50 > 100 mg/L). However, in wastewater treatment and natural aquatic environments, aerobic/anaerobic biodegradation of the polyoxyethylene chain slowly cleaves NPEs into shorter-chain ethoxylates (NP1EO, NP2EO) and branched 4-nonylphenol (NP), which are persistent, bioaccumulative, and endocrine-disrupting to aquatic organisms.
  - EU REACH Annex XIV & Annex XVII Restrictions: In the European Union / EEA, Nonylphenol Ethoxylates (NPEs) are included on the REACH SVHC Candidate List and Authorization List (Annex XIV) and restricted under REACH Annex XVII Entry 46 & Entry 46a (prohibiting placement on the market in textile articles washable in water at >= 0.01% w/w and restricting open industrial/domestic discharges above 0.1% w/w unless used in closed systems with zero wastewater release or authorized exemptions). Conversely, in many non-EU jurisdictions, closed-loop polymerization systems, and permitted export applications (as well as US EPA 40 CFR 180.910/180.920 agrochemical inert uses), TERGITOL NP-30 Surfactant remains an established industrial raw material; always verify regional regulatory compliance for your target market.

- Personal Protective Equipment (PPE) & First Aid:
  - Wear safety glasses or chemical splash goggles (EN 166), nitrile or neoprene gloves (EN 374; thermal-insulated gloves when handling molten 55 °C liquid), and standard protective work clothing.
  - Eye Contact: Immediately flush eyes with plenty of lukewarm running water for at least 15 minutes while holding eyelids open; seek medical attention if irritation persists.
  - Skin Contact: Wash skin thoroughly with soap and water. If contacted by hot molten surfactant, cool skin immediately with cold water.
  - Inhalation: Move to fresh air if hot mist or dust is inhaled.
  - Ingestion: Rinse mouth with water and drink 1 glass of water if conscious; do NOT induce vomiting and consult a physician if unwell.

WHAT SHOULD BE CONSIDERED WHEN PURCHASING TERGITOL NP-30 SURFACTANT?

Select Between 100% Active Solid/Flake Grade and 70% Active Aqueous Liquid Grade: If your plant prefers room-temperature liquid metering without heating drums to 50 °C, specify TERGITOL NP-30 (70% Aq) Surfactant; if you require water-free compounding, dry powder blending (WP/WDG), or lower freight cost per active ton, specify 100% Active Solid/Flaked TERGITOL NP-30 Surfactant.
Verify Cloud Point (> 100 °C in 1% Water and 72–76 °C in 10% NaCl) and Hydroxyl Value (34–39 mg KOH/g): Confirm on the batch Certificate of Analysis that the ethoxylation degree is genuinely 30 moles EO (MW ~1,540 g/mol, HLB 17.1), ensuring zero reactor coagulation during 80–95 °C emulsion polymerization.
For Emulsion Polymerization of Light-Colored Latices and Clear Coatings, Check Molten APHA Color (<= 50 to 100 APHA) and pH (5.5 to 7.5): Low residual alkalinity and low peroxide color ensure zero yellowing or monomer hydrolysis during polymerization.
Evaluate Target-Market Regulatory Compliance (EU REACH vs. Non-EU / Closed-Loop Markets): Confirm whether the finished latex, paint, textile, or agrochemical product will be sold in a market that permits NPE surfactants or requires an APE-free alcohol ethoxylate alternative (both available from Ataman Kimya).
Ensure Proper Dilution Order in Production: Instruct plant operators to dissolve 100% active TERGITOL NP-30 Surfactant into agitated warm water (50–65 °C) rather than adding cold water onto solid blocks to avoid slow-dissolving gel phases.

FREQUENTLY ASKED QUESTIONS ABOUT TERGITOL NP-30 SURFACTANT

 What is the HLB value, molecular weight, and ethoxylation degree of TERGITOL NP-30 Surfactant?
TERGITOL NP-30 Surfactant is a nonionic surfactant containing an average of 30 moles of ethylene oxide (EO) per mole of branched 4-nonylphenol. It has an average molecular weight of ~1,540 g/mol and a Griffin Hydrophile-Lipophile Balance (HLB) of 17.1 (85.7% hydrophilic polyoxyethylene by weight).

 Why is TERGITOL NP-30 Surfactant a solid at room temperature whereas TERGITOL NP-9 is a liquid?
In nonylphenol ethoxylates, the melting/pour point increases with the length of the crystalline polyoxyethylene (PEG) chain: 9-mole TERGITOL NP-9 (MW ~616 g/mol) has a pour point of 0 °C and is a liquid at room temperature, whereas 30-mole TERGITOL NP-30 Surfactant (MW ~1,540 g/mol) has a pour/melting point of ~40 °C (104 °F), making the 100% active grade a white waxy solid or flake below 37 °C and a clear mobile liquid above 42 °C. (A 70% w/w solution in water, TERGITOL NP-30 70% Aq, is also available as a room-temperature pumpable liquid.)

Why is TERGITOL NP-30 Surfactant preferred over NP-9 or NP-10 in emulsion polymerization?
Emulsion polymerization of acrylics, styrene-acrylics, PVAc, and VAE is typically run at 75 to 90 °C. Because NP-9 and NP-10 have cloud points of only 54 °C and 63 °C, they dehydrate and separate out of water at reactor temperatures—causing severe coagulum ("grit"). TERGITOL NP-30 Surfactant has a cloud point > 100 °C in water and a long 30-EO chain that stays 100% hydrated at 90 °C, preventing reactor coagulum and imparting Ca2+ electrolyte and freeze-thaw stability to the finished latex.

How do you dissolve 100% active solid or flaked TERGITOL NP-30 Surfactant in water without forming gel lumps?
Never dump cold water directly onto a solid block of 100% active TERGITOL NP-30 Surfactant, as concentrations around 40%–55% in cold water can form a slow-dissolving hexagonal liquid-crystalline gel phase. Instead, either pre-melt the surfactant at 50–60 °C or charge the flakes slowly into agitated warm water heated to 50 to 65 °C, where it dissolves rapidly into a clear solution within minutes.

What is the cloud point of TERGITOL NP-30 Surfactant in pure water and in salt solutions?
In a 1% w/w solution in pure deionized water, the cloud point of TERGITOL NP-30 Surfactant is > 100 °C (it remains completely clear at atmospheric boiling). In a concentrated 10% w/w sodium chloride (NaCl) brine solution, its cloud point is approximately 72 to 76 °C—allowing it to function in high-electrolyte cleaners, agrochemicals, and oilfield brines where standard nonionics salt out immediately.

Can TERGITOL NP-30 Surfactant be combined with anionic surfactants like SLS, SLES, or SDBS?
Yes! Pairing TERGITOL NP-30 Surfactant (at 1.5% to 2.5% w/w on monomer) with an anionic surfactant such as Sodium Lauryl Sulfate (SLS), Sodium Lauryl Ether Sulfate (SLES), or Sodium Dodecylbenzenesulfonate (SDBS, at 0.2% to 0.6% w/w) is the industry-standard dual emulsifier system for emulsion polymerization—combining fast anionic micellar particle nucleation with nonionic 30-EO steric, shear, electrolyte, and freeze-thaw stability.

Why does post-adding TERGITOL NP-30 Surfactant make SBR and acrylic latices compatible with Portland cement?
When an un-post-stabilized carboxylated SBR or acrylic latex is mixed into Portland cement (pH ~12.8, saturated with divalent Ca2+ and trivalent Al3+ ions), the multivalent cations bridge the negatively charged latex particles and cause immediate coagulation. Post-adding 1.0% to 2.0% w/w TERGITOL NP-30 Surfactant coats the latex spheres with an uncharged 30-EO steric hydration layer that physically prevents Ca2+-induced particle contact.

How does TERGITOL NP-30 Surfactant prevent "flooding and floating" (color rub-up) in tinted waterborne paints?
When hydrophobic organic pigments (like Phthalocyanine Blue or Carbon Black) are dispersed into waterborne paints, electrolyte shock can cause them to flocculate and separate from coarse TiO2 particles. The aromatic nonylphenol ring of TERGITOL NP-30 Surfactant adsorbs strongly onto the organic pigment crystal while its 30-EO tail stabilizes the pigment sterically in the aqueous phase, eliminating color differences under shear.

Is TERGITOL NP-30 Surfactant classified as dangerous goods or a marine pollutant for transport?
No. Unlike lower-ethoxylation liquid nonylphenol ethoxylates (such as NP-4 through NP-12, which are often classified under UN 3082 Class 9 due to acute aquatic toxicity), high-molecular-weight 30-mole TERGITOL NP-30 Surfactant exhibits low acute aquatic toxicity (96-h fish LC50 > 50–100 mg/L) and is NOT regulated as dangerous goods under ADR, RID, IMDG, or IATA transport regulations.

What should formulators exporting to the European Union consider regarding TERGITOL NP-30 Surfactant?
Within the European Union, nonylphenol ethoxylates (NPEs) are subject to REACH Annex XIV authorization and Annex XVII Entry 46/46a restrictions (particularly in washable textiles and open wastewater discharges). For EU-regulated or eco-labeled formulations, Ataman Kimya can supply APE-free high-EO secondary or linear alcohol ethoxylate equivalents (such as 30-EO alcohol ethoxylates with HLB ~17.4), whereas for permitted closed-loop, industrial, and non-EU markets, TERGITOL NP-30 Surfactant provides benchmark performance and economy.
