Supragil RM/210-EI—widely traded across global agrochemical, synthetic rubber latex, pigment dispersion, textile dyestuff, and construction chemical markets under its industrial and chemical synonyms Anionic Alkyl Naphthalene Sulfonate Sodium Salt Dispersant, Sodium Diisopropyl / Methyl Naphthalene Sulfonate Condensate, Alkyl Naphthalene Sulfonate Formaldehyde Condensate (RM/210-EI Grade), Low-Foaming Agrochemical Wetting and Dispersing Agent, and Sodyum Alkil Naftalin Sülfonat (Supragil RM/210-EI)—is a water-soluble, strongly anionic surfactant, wetting agent, and polymeric dispersing auxiliary engineered for solid-phase particulate suspensions and emulsion stabilization. Across global manufacturing, crop-protection formulators rely on Supragil RM/210-EI to favor the rapid water opening, capillary wetting, and long-term suspension stability of hydrophobic solid active ingredients in Water Dispersible Granules (WDG / WG), Wettable Powders (WP), Suspension Concentrates (SC), Suspo-Emulsions (SE), and Seed Treatment (FS) formulations, while synthetic elastomer plants, pigment grinders, textile dyehouses, and construction chemical producers deploy it to prevent Styrene-Butadiene Rubber (SBR) and Nitrile (NBR) latex coagulation, deflocculate organic pigments and disperse dyes, and fluidize mineral admixtures.
At the molecular level, Supragil RM/210-EI combines alkyl-substituted bicyclic 10-pi-electron naphthalene aromatic rings—carrying branched isopropyl and/or methyl alkyl groups (C1 to C6 alkyl substitution across monomeric and methylene-bridged oligomeric chains)—with permanently ionized hydrophilic sodium sulfonate headgroups (-SO3- Na+). This tailored amphiphilic and polyaromatic architecture performs a dual interfacial action: the agile alkylated naphthalene sulfonate domains migrate rapidly to solid-liquid interfaces to depress contact angle and drive fast capillary water penetration into dry powder beds and WDG granules, while the condensed aromatic sulfonate chains anchor onto hydrophobic pesticide crystal faces, pigment surfaces, and SBR latex spheres via pi-pi stacking and van der Waals attraction to generate a high negative zeta potential (-40 to -60 mV).
Agrochemical, latex, and pigment chemists select Supragil RM/210-EI over conventional wood-derived lignosulfonates, linear alkylbenzene sulfonates (LAS), and nonionic alkylphenol or fatty alcohol ethoxylates because Supragil RM/210-EI delivers rapid solid-phase opening and wetting alongside strong electrostatic dispersion while maintaining a controlled low-foaming profile during high-shear wet bead milling and field spray-tank agitation. Furthermore, compared to unsubstituted sodium naphthalene sulfonate condensates (SNF) or pH-sensitive polycarboxylates, the alkyl-modified naphthalene sulfonate structure of Supragil RM/210-EI exhibits superior solubility in alkaline and acidic media alike (pH 1.0 to 14.0), complete tolerance to hard agricultural spray waters (342 ppm to 1,000 ppm CaCO3), zero thermal cloud point up to 100 °C in aqueous baths, thermal drying stability above 220 to 250 °C in fluid-bed and spray dryers, and full compatibility with Styrene-Butadiene Rubber (SBR) emulsions.
Supplied commercially by Ataman Kimya as a free-flowing light-tan to buff spray-dried powder or water-dispersible micro-granule (active alkylnaphthalene sulfonate content 85.0% to 92.0% w/w, bulk pour density 440 to 650 g/L, moisture <= 3.0% to 5.0% w/w, and water-insolubles <= 0.05% to 0.10% w/w), Supragil RM/210-EI is manufactured with controlled low inorganic sodium sulfate and ultra-low residual free formaldehyde to meet global agrochemical and industrial compliance standards. Matching the target formulation type (WP, WDG/WG, SC, SBR latex, pigment paste, or alkaline cleaner) with the quantitative wetting, dispersing, and electrolyte specifications of Supragil RM/210-EI ensures rapid granule disintegration, zero nozzle clogging, and multi-year shelf stability.

WHAT IS SUPRAGIL RM/210-EI?
Known across international agrochemical, elastomer latex, pigment, and construction chemical commerce as Supragil RM/210-EI (and in Turkish industrial trade as Sodyum Alkil Naftalin Sülfonat RM/210-EI, Anyonik Zirai İlaç Islatma ve Dispersiyon Ajanı, or SBR Lateks Stabilizatörü), Supragil RM/210-EI is a specialty, water-soluble, low-foaming anionic surfactant, wetting agent, and polymeric dispersing auxiliary based on alkyl-substituted naphthalene sulfonate sodium salt chemistry. Engineered originally within the flagship Supragil agricultural and industrial surfactant portfolio (developed by Rhodia / Solvay / Syensqo), Supragil RM/210-EI is specifically designed to bridge the functional gap between pure monomeric alkylnaphthalene sulfonate wetting agents (such as Supragil WP) and pure high-molecular-weight methylnaphthalene sulfonate formaldehyde condensate dispersants (such as Supragil MNS/90 and Supragil MNS/88-E).
In global chemical inventories, European plant-protection co-formulant lists, patent literature (such as EP 1586237 A1 for agricultural water-dispersible granules), and US EPA inert-ingredient databases, Supragil RM/210-EI is indexed under the alkylnaphthalene sulfonic acid sodium salt and formaldehyde condensate registries—specifically CAS No. 68425-94-5 (EC No. 614-476-8 / 270-115-0, sulfonated alkyl/methyl aromatic fractionator polymers with formaldehyde, sodium salts), CAS No. 81065-51-2 (EC No. 617-194-3, methylnaphthalenesulfonic acid polymer with formaldehyde, sodium salt), CAS No. 1322-93-6 (EC No. 215-343-3, sodium diisopropylnaphthalenesulfonate, C16H19NaO3S), and CAS No. 9084-06-4. This tailored alkyl-naphthalene sulfonate architecture delivers three simultaneous technical capabilities in a single free-flowing powder or water-dispersible micro-granule:
Rapid Solid-Phase Wetting and Granule Opening ('Bloom'): Unlike unalkylated or purely high-polymeric naphthalene sulfonate condensates (which exhibit high surface tensions of 60 to 68 mN/m and slow initial wetting of hydrophobic powders), the branched isopropyl/methyl alkyl-naphthalene sulfonate domains in Supragil RM/210-EI rapidly reduce dynamic solid-liquid interfacial tension and aqueous surface tension (down to ~38 to 50 mN/m). When dry Wettable Powders (WP) or compressed Water Dispersible Granules (WDG / WG) contact spray-tank water, Supragil RM/210-EI drives immediate capillary water wicking into micro-pores, favoring the rapid opening, deaggregation, and dispersion of solid-phase active substances within seconds.
Electrosteric Particle Dispersion and Suspension Stabilization: Once the solid agglomerates open in water—or when technical active ingredients and pigments are fractured inside a wet zirconia bead mill—the planar alkyl-naphthalene aromatic rings of Supragil RM/210-EI adsorb onto the hydrophobic crystal faces via pi-pi stacking and hydrophobic bonding. The outward-oriented sodium sulfonate groups (-SO3- Na+, pKa < -1.5) dissociate 100% in water to establish a strong negative zeta potential (-40 to -60 mV), preventing crystal flocculation, cutting millbase viscosity, and maintaining uniform water suspensions without excessive foaming.
Full Compatibility and Anti-Coagulation Power in Styrene-Butadiene Rubber (SBR) and Synthetic Latices: A signature differentiating property of Supragil RM/210-EI is its exceptional compatibility with Styrene-Butadiene Rubber (SBR), carboxylated SBR (X-SBR), Nitrile-Butadiene Rubber (NBR), and Polychloroprene (CR) emulsion latices. Adding Supragil RM/210-EI directly to polymer latices—or using it to disperse vulcanization curatives (sulfur, zinc oxide, accelerators, antioxidants, and mineral fillers) prior to latex compounding—prevents mechanical shear coagulation, calcium/electrolyte shock, and filler-induced gum formation.
CHEMICAL STRUCTURE, MOLECULAR ARCHITECTURE AND INTERFACIAL CHEMISTRY
Understanding why Supragil RM/210-EI excels across both agrochemical solid/liquid formulations and synthetic rubber latex compounding requires examining its three-part molecular design:
The Alkyl-Substituted Bicyclic Naphthalene Hydrophobic Core:
The hydrophobic anchor of Supragil RM/210-EI is built upon the rigid, planar 10-pi-electron naphthalene ring system (C10H8) substituted with short branched and linear aliphatic alkyl chains—specifically isopropyl (-CH(CH3)2) and methyl (-CH3) groups. Attaching isopropyl and methyl groups onto the aromatic naphthalene rings increases the molar hydrophobic volume and lowers the critical aggregation concentration compared to unsubstituted naphthalene sulfonates. This enables the aromatic core to interact strongly both with planar aromatic pesticide molecules (such as triazoles, strobilurins, phenylureas, neonicotinoids, and pyrethroids) via pi-pi electron-donor-acceptor stacking and with aliphatic/aromatic polymer chains on the surface of Styrene-Butadiene Rubber (SBR) latex droplets.
Balanced Monomeric-to-Oligomeric Methylene-Bridged Chain Distribution:
In Supragil RM/210-EI, the combination of agile alkylnaphthalene sulfonate wetting species (MW ~314.38 g/mol for C16H19NaO3S sodium diisopropylnaphthalene sulfonate) and methylene-bridged (-CH2-) alkylnaphthalene sulfonate formaldehyde condensate oligomers (repeating unit (C11H9NaO3S·CH2O)n, Mw ~1,000 to 4,500 g/mol) creates a 'fast-wetting plus permanent-anchoring' bimodal mechanism. During the first 1 to 10 seconds of water contact, the faster-diffusing alkylnaphthalene sulfonate species wet the hydrophobic solid-air interface and displace trapped air pockets; immediately thereafter, the multi-ring methylene-bridged oligomers lock onto the wetted crystal faces in a flat train-and-loop conformation that resists desorption even upon 1:200 to 1:1,000 field spray-tank dilution.
The Permanently Ionized Sodium Sulfonate (-SO3- Na+) Headgroup:
Because aromatic sulfonic acids possess a strongly negative pKa (< -1.5), the sodium sulfonate headgroups (-SO3- Na+) of Supragil RM/210-EI remain completely ionized across the entire pH range from pH 1.0 (strongly acidic pickling or chemical synthesis baths) to pH 14.0 (concentrated alkaline industrial degreasers, cement pore water, and high-pH potassium hydroxide latex compounds). Moreover, the sterically bulky alkyl-naphthalene rings shield the adjacent sulfonate anions from forming insoluble precipitates with divalent calcium (Ca2+) and magnesium (Mg2+) ions, conferring exceptional hard-water stability in CIPAC Standard Waters A, D (342 ppm), and C (500 to 1,000 ppm CaCO3), especially in neutral to alkaline environments.
Decoding the '-EI' Suffix in Supragil RM/210-EI:
Within the Supragil designation, 'RM/210' identifies the specific alkylnaphthalene sulfonate wetting-dispersing ratio, while '-EI' designates the engineered Easy-dispersing / Extruded Industrial and European-compliant grade featuring low-dust micro-granular/powder morphology, rapid cold-water dissolution without lumping, and strictly controlled residual free formaldehyde (<= 0.05% to 0.10% w/w).
INDUSTRIAL PRODUCTION AND MANUFACTURING PROCESSES
Commercial Supragil RM/210-EI is manufactured in specialized corrosion-resistant reactors through a four-stage chemical synthesis and particle-engineering sequence: (1) Catalytic Alkylation of Naphthalene/Methylnaphthalene, (2) Regioselective High-Temperature Sulfonation, (3) Controlled Formaldehyde Condensation & Co-Processing, and (4) Alkaline Neutralization, Sulfate Refining, and Spray-Dry Micro-Granulation.
Step 1: Catalytic Friedel-Crafts Alkylation and Feedstock Preparation: Refined naphthalene and alpha-/beta-methylnaphthalene feedstocks are reacted with propylene or isopropanol (at controlled molar ratios) in the presence of an acid catalyst (such as sulfuric acid, phosphoric acid, or activated clay/zeolite) at 110 to 150 °C to produce a tailored mono- and di-alkylated (isopropyl/methyl) naphthalene aromatic cut.
Step 2: Regioselective Beta-Sulfonation with Concentrated Sulfuric Acid or Oleum: The alkylated/methylated naphthalene intermediate is charged into a glass-lined or high-alloy agitated reactor and sulfonated with 98% concentrated sulfuric acid or 20% oleum at 135 to 155 °C for 2 to 4 hours. Operating at elevated temperature under thermodynamic control directs the incoming sulfonic acid group (-SO3H) predominantly onto the unhindered beta-positions of the naphthalene rings, maximizing planar adsorption geometry and aqueous solubility.
Step 3: Controlled Formaldehyde Polycondensation and Steam Stripping: The sulfonated alkyl/methylnaphthalene mass is cooled to 90 to 105 °C, adjusted with process water, and reacted with a metered stoichiometric charge of aqueous formaldehyde (37% formalin) at 100 to 120 °C under pressure to link the aromatic sulfonic acid units via covalent methylene bridges (-CH2-) to the target oligomeric molecular weight window, while retaining the desired fraction of rapid-wetting diisopropylnaphthalene sulfonate species. Vacuum and steam stripping are then applied to drive residual free formaldehyde below 500 ppm (0.05% w/w).
Step 4: Caustic Neutralization, Sulfate Desalting, and Spray-Dried '-EI' Conditioning: Excess sulfuric acid is removed via lime-gypsum precipitation (CaSO4·2H2O filtration), and the sulfonic acid groups are neutralized with aqueous sodium hydroxide (NaOH) to pH 7.5–9.5, keeping inorganic sodium sulfate (Na2SO4) below 7.0%–10.0% w/w. Finally, the concentrated 42%–48% aqueous liquor is atomized in a co-current spray-drying tower with integrated fluid-bed agglomeration (inlet air 185 to 220 °C, outlet air 85 to 95 °C) to yield free-flowing, low-dust, rapidly water-dispersible buff powder/micro-granules of Supragil RM/210-EI.

WHY EACH IMPORTANT PROPERTY OF SUPRAGIL RM/210-EI MATTERS IN PRACTICE
Formulation chemists in crop protection, synthetic rubber latex compounding, pigment milling, and industrial detergents monitor specific quantitative parameters of Supragil RM/210-EI because each metric directly impacts processing speed and end-product stability:
Balanced Surface Tension Depression (38 to 52 mN/m at 0.5%–1.0% w/w) and Fast Wetting (< 15–35 s): Pure polymeric naphthalene sulfonate condensates (like Supragil MNS/90) have high surface tensions (~60 mN/m) and cannot wet hydrophobic pesticide powders on their own, whereas standard lauryl sulfate or linear alkylbenzene sulfonate wetters lower surface tension to 30 mN/m but create massive, persistent foam columns that overflow bead mills and spray tanks. Supragil RM/210-EI hits the exact interfacial 'sweet spot': it lowers surface tension enough to wet hydrophobic crystals and force water into WDG/WP pores in seconds, while its rigid bicyclic alkylnaphthalene structure prevents stable soap-bubble lamellae, collapsing foam within 60 seconds!
High Solubility and Stability in Alkaline Conditions (pH 7.5 to 14.0): Many agrochemical tank mixes, SBR/NBR rubber latices (stabilized with KOH or ammonia at pH 9.5 to 11.5), cementitious mortars (pH 12.5 to 13.5), and heavy-duty industrial cleaners operate at high alkalinity where ester-based surfactants or polyacrylates hydrolyze and nonionic ethoxylates salt out. Supragil RM/210-EI contains only carbon-carbon, aromatic carbon-sulfur, and methylene bonds that never hydrolyze even in boiling caustic alkali.
Compatibility with Styrene-Butadiene Rubber (SBR) Latices and Prevention of Coagulation: When dry mineral fillers (calcium carbonate, kaolin clay), pigments (TiO2, carbon black), or vulcanization curatives (sulfur, ZnO, ZDEC) are added directly to an SBR or NBR latex without proper anionic pre-wetting and dispersion, the filler particles strip soap molecules off the polymer latex spheres and trigger immediate, irreversible latex coagulation (gum balls). Pre-wetting or co-formulating with 0.5% to 2.5% w/w Supragil RM/210-EI coats both the filler/curative particles and the SBR latex droplets with a compatible alkylnaphthalene sulfonate double layer (-45 to -55 mV), completely preventing mechanical shear and electrolyte coagulation.
High Thermal Decomposition Onset (> 240 °C) and Zero Cloud Point (> 100 °C): During fluid-bed drying (65–90 °C), basket extrusion, or high-tower spray drying (180–220 °C inlet air) of Water Dispersible Granules (WDG), low-melting nonionic surfactants (MP 35–50 °C) melt into sticky pastes that foul extruder dies and cause severe granule caking in storage. Supragil RM/210-EI remains a crisp, high-Tg solid up to >240 °C, acting as a non-sticky disintegrating aid, and never clouds out in hot water.
Low Water-Insoluble Matter (<= 0.05%–0.10% on 325-Mesh Sieve) and Low Sodium Sulfate (<= 6%–10%): Guarantees zero nozzle clogging in agricultural boom sprayers and prevents electrolyte-induced viscosity drift or sub-zero Glauber's salt crystallization in liquid Suspension Concentrates (SC).
HOW DOES SUPRAGIL RM/210-EI WORK AT THE MOLECULAR AND INTERFACIAL LEVEL?
Supragil RM/210-EI operates through four synergistic physicochemical mechanisms across solid-in-water suspensions, dry granules, and polymer emulsions:
Capillary Wetting and Solid-Phase Opening (Washburn Penetration Enhancement): According to the Lucas-Washburn capillary equation, the rate at which water penetrates into the microscopic pores of a dry Wettable Powder (WP) bed or a compressed Water Dispersible Granule (WDG) is proportional to (gamma_LV x cos(theta)), where theta is the contact angle on the hydrophobic pesticide crystal. Unformulated technical pesticides (such as tebuconazole, sulfur, mancozeb, diuron, or imidacloprid) have water contact angles > 90° (cos(theta) < 0), so they float on water without wetting. Upon contact with water, the isopropyl/methyl-naphthalene sulfonate molecules in Supragil RM/210-EI adsorb instantaneously at the advancing three-phase contact line, dropping the contact angle theta below 20° (cos(theta) -> 0.94) and driving rapid capillary water incursion that splits and opens the solid granule from the inside out.
Planar Pi-Pi Aromatic Adsorption onto Hydrophobic Crystals and Latex Spheres: Once water penetrates the solid bed—or as crystals are fractured inside a wet zirconia bead mill—the planar bicyclic alkylnaphthalene rings of Supragil RM/210-EI align flat against the hydrophobic aromatic or aliphatic surfaces of the active ingredient, pigment, or SBR copolymer particle. The combination of pi-pi electron stacking and hydrophobic dehydration of the isopropyl/methyl side groups anchors the surfactant chains firmly against the solid surface.
Electrostatic Double-Layer Repulsion (DLVO Stabilization): With the hydrophobic alkylnaphthalene rings anchored to the particle surface, the ionized sodium sulfonate groups (-SO3- Na+) extend into the aqueous continuous phase, surrounding each particle or latex droplet with a dense negative surface charge (zeta potential -40 to -60 mV) and a tightly bound hydration shell. When two particles collide under Brownian motion, high-speed pumping shear, or gravity, the repulsive electrostatic barrier prevents van der Waals aggregation, converting thick, coagulated pastes into low-viscosity, free-flowing suspensions.
Anti-Redeposition and Soil/Pigment Suspension in Alkaline Cleaning and Dyeing: In industrial cleaning and textile scouring baths, Supragil RM/210-EI adsorbs onto dislodged particulate soils, carbon soot, and insoluble pigment residues as well as onto the substrate surface, imparting mutual negative electrostatic repulsion that keeps dirt suspended in the wash liquor and prevents greying or surface redeposition.
WHAT PROBLEMS CAN SUPRAGIL RM/210-EI HELP SOLVE?
Formulators across crop protection, rubber latex processing, pigment dispersion, and construction chemicals deploy Supragil RM/210-EI to solve six common formulation and manufacturing bottlenecks:
Slow wetting, floating powder, and incomplete granule opening ('hard cores') in WP and WDG pesticides
When hydrophobic pesticide powders or extruded WDG granules are formulated solely with high-MW polymeric dispersants or lignosulfonates, they wet too slowly (> 2 minutes) and leave undispersed granule cores at the bottom of the spray tank. Incorporating 2.0% to 6.0% w/w of Supragil RM/210-EI favors rapid solid-phase opening and capillary water entry, cutting CIPAC wetting time below 15 to 30 seconds and achieving complete granule disintegration within 5 to 10 cylinder inversions.
Excessive persistent foam during wet bead milling and field spray-tank agitation
Standard wetting agents (such as sodium lauryl sulfate, alpha-olefin sulfonates, or high-dosage dioctyl sulfosuccinate) whip air into stable foam during horizontal bead milling of SC flowables or field tank mixing. Supragil RM/210-EI delivers strong wetting and dispersing power with a low-foaming alkylnaphthalene sulfonate profile that collapses rapidly.
Coagulation and gum-ball formation in Styrene-Butadiene Rubber (SBR) and Nitrile (NBR) latices
Adding dry mineral fillers, pigments, or sulfur/ZnO vulcanization curatives—or applying high-shear pumping—causes insufficiently stabilized SBR and NBR latices to coagulate and foul dip tanks, carpet-backing coaters, and paper-coating blades. Adding 0.5% to 2.5% w/w Supragil RM/210-EI stabilizes the latex against mechanical shear and divalent cation shock.
High millbase viscosity and pigment/active reagglomeration during wet grinding
When grinding 45%–55% w/w pesticide SCs, sulfur/accelerator dispersions, or organic pigment pastes, freshly cleaved sub-micron surfaces flocculate into an unpumpable gel. Dosing 1.5% to 4.0% w/w Supragil RM/210-EI wets the hydrophobic powder immediately during pre-mixing and maintains low Newtonian viscosity (< 300 mPa·s) throughout sub-micron bead milling.
Granule stickiness and thermal caking in low-melting pesticide WDG formulations
As demonstrated in agricultural WDG engineering (e.g., EP 1586237 A1 for low-melting technical actives with softening points <= 70 °C), liquid or waxy nonionic surfactants plasticize the active ingredient and cause severe extrusion die blockage and storage caking. Because Supragil RM/210-EI is a dry, high-decomposition-temperature (>240 °C) aromatic sulfonate salt, it enables crisp, non-sticky granulation and caking-free 54 °C storage.
Poor hard-water performance and particulate soil redeposition in alkaline industrial cleaners
Conventional soaps and many anionic surfactants precipitate as sticky calcium scum in hard water (> 300 ppm CaCO3) or lose activity in strong caustic cleaners. Supragil RM/210-EI remains crystal-clear and active in > 500–1,000 ppm hard water and concentrated alkali, keeping removed soils and pigments suspended without redeposition.

USE OF SUPRAGIL RM/210-EI IN AGROCHEMICAL FORMULATIONS (WDG/WG, WP, SC, SE AND FS)
In agricultural crop protection, Supragil RM/210-EI is prized for its ability to promote the rapid opening and dissolution/dispersion of solid-phase active substances in water while maintaining high suspension stability:
- Water Dispersible Granules (WDG / WG — Extruded, Fluid-Bed, Spray-Dried, and Pan-Granulated, 2.0% to 8.0% w/w): In WDG formulations containing 50% to 90% w/w hydrophobic solid active ingredients (such as tebuconazole, mancozeb, sulfur, copper oxychloride, atrazine, diuron, metribuzin, imidacloprid, acetamiprid, thiamethoxam, chlorothalonil, or iminoctadine salts), Supragil RM/210-EI acts as a dual wetting-opening agent and dispersing binder. When paired at 2.0% to 4.0% w/w alongside 4.0% to 7.0% w/w of a higher-MW condensate like Supragil MNS/90 or Supragil MNS/88-E (or used at 4.0% to 8.0% w/w as the primary wetting-dispersing package), Supragil RM/210-EI ensures rapid water wicking into the granule core, cutting disintegration time below 15 to 30 seconds and achieving >= 90%–96% CIPAC MT 184 suspensibility in 342 ppm and 500 ppm CaCO3 hard waters.
- Wettable Powders (WP — Air-Jet and Mechanical Micronized Powders, 2.0% to 6.0% w/w): Co-blended with the technical active ingredient and kaolin/silica carrier prior to air-jet micronization (d50 = 2 to 5 microns). Supragil RM/210-EI coats freshly fractured hydrophobic crystal surfaces inside the jet mill, preventing static reagglomeration and ensuring that the finished WP powder wets and sinks in water in < 20 to 35 seconds (CIPAC MT 53.3) without generating excessive tank foam.
- Suspension Concentrates (SC), Suspo-Emulsions (SE), and Flowable Seed Treatments (FS, 1.0% to 4.0% w/w): Charged into the aqueous pre-mix vessel prior to horizontal bead milling. Supragil RM/210-EI rapidly wets floating technical powders into the water phase without air entrainment, slashes millbase yield stress during sub-2-micron grinding, and works synergistically with nonionic EO-PO block copolymers or acrylic graft copolymers to prevent Ostwald crystal ripening and hard-pack claying during 54 °C storage.
USE OF SUPRAGIL RM/210-EI IN STYRENE-BUTADIENE RUBBER (SBR) LATEX, PIGMENTS AND TEXTILES
- Styrene-Butadiene Rubber (SBR) and Synthetic Latex Stabilization (0.5% to 3.0% phm on dry rubber weight): Supragil RM/210-EI is directly compatible with cold and hot emulsion SBR latices (including SBR 1502 / 1500 / 1712 latices and carboxylated X-SBR latices), NBR latices, polychloroprene (CR) latices, and natural rubber (NR) latices. Added at 0.5% to 2.5% phm during polymerization, monomer stripping, or post-compounding, Supragil RM/210-EI adsorbs onto the polymer latex particles to boost mechanical shear stability (high-speed Hamilton Beach stir test) and chemical stability against calcium/zinc electrolyte shock when compounding dipped gloves, foam mattresses, carpet backings, and waterproof bitumen-latex emulsions.
- Aqueous Curative Dispersion Milling for Latex Compounding (1.5% to 4.5% w/w): Vulcanizing rubber latex requires adding water-insoluble powders—elemental sulfur, zinc oxide (ZnO), titanium dioxide (TiO2), zinc diethyldithiocarbamate (ZDEC), zinc dibutyldithiocarbamate (ZDBC), and phenolic antioxidants—as sub-2-micron aqueous slurries (50%–60% solids). Ball-milling or attritor-milling these powders with 2.0% to 4.0% w/w Supragil RM/210-EI at pH 9.0–10.5 produces low-viscosity, foam-free curative dispersions that blend into SBR and NBR latices with zero coagulum.
- Aqueous Pigment Dispersions, Carbon Black, and Textile Disperse/Vat Dyes (3.0% to 40.0% on pigment/dye weight): Accelerates initial pigment wetting and stabilizes sub-micron aqueous dispersions of Phthalocyanine Blues/Greens, Azo pigments, Iron Oxides, Carbon Black, and Disperse/Vat textile dyes, maintaining dispersion stability up to 130–140 °C in high-temperature polyester dyeing.
USE OF SUPRAGIL RM/210-EI IN CONSTRUCTION CHEMICALS AND INDUSTRIAL CLEANERS
- Construction Admixtures, Dry-Mix Mortars, and Gypsum / Ceramic Slurries (0.2% to 1.5% w/w): In cementitious tile adhesives, self-leveling underlayments (SLUs), non-shrink grouts, concrete water-reducing admixtures, and gypsum wallboard stucco slurries, Supragil RM/210-EI rapidly wets hydrophobic redispersible polymer powders (RDP), silica fume, and fly ash while deflocculating cement and mineral filler particles to improve slump flow, pumpability, and compressive strength.
- Industrial & Institutional (I&I) Alkaline Cleaners and Anti-Redeposition Baths (0.5% to 4.0% w/w): In caustic bottle-washing solutions, heavy-duty alkaline metal degreasers, and hard-surface industrial cleaners, Supragil RM/210-EI remains completely soluble at pH 10 to 14 and in hard water, wetting oily particulate soils and keeping carbon soot, pigments, and insoluble residues suspended so they cannot redeposit onto cleaned metal, glass, or plastic surfaces.
FORMULATION AND PROCESS CONSIDERATIONS WHEN USING SUPRAGIL RM/210-EI
To maximize the wetting, granule-opening, and dispersing performance of Supragil RM/210-EI in plant production, formulators should observe five practical engineering guidelines:
Pairing with Polymeric Condensates (Supragil MNS/90 or MNS/88-E) in High-Load WDGs and SCs: While Supragil RM/210-EI can serve as a standalone wetting-dispersing agent in many WP and medium-load WDG recipes (at 4% to 7% w/w), in ultra-high-load (75%–90% AI) WDG granules or low-melting-point SC formulations, combining 1.5% to 3.5% w/w Supragil RM/210-EI (for rapid wetting and solid-phase opening) with 4.0% to 6.5% w/w Supragil MNS/90 or Supragil MNS/88-E (for maximum high-MW multi-ring crystal anchoring) yields optimal 54 °C storage stability and < 15-second granule bloom.
Order of Addition in Wet Bead Milling (SC / SE / Curative Pastes): Always dissolve Supragil RM/210-EI completely in the deionized water (and antifreeze glycol) phase for 10 to 15 minutes before charging the hydrophobic active ingredient, sulfur, or pigment powder. Adding the hydrophobic powder into a pre-dissolved Supragil RM/210-EI solution allows instantaneous wetting and prevents floating powder lumps from fouling the mixer shaft.
Co-Micronization in Air-Jet Mills for WP and WDG Pre-Mixes: In dry WP and WDG manufacturing, dry-blend Supragil RM/210-EI powder thoroughly with the technical active ingredient and inert carrier (kaolin, silica, ammonium sulfate) before passing the mixture through the air-jet mill (fluid-energy micronizer). Co-milling ensures that Supragil RM/210-EI is intimately smeared across the high-energy crystal cleavage planes the instant they are created.
pH Adjustment in SBR / NBR Latex Stabilization: When adding an aqueous solution of Supragil RM/210-EI (typically 10% to 25% w/w stock solution) to an alkaline SBR or NBR latex (pH 9.5 to 11.0), verify that the stock solution pH is between 8.5 and 10.5 (adjusting with a few drops of dilute KOH or NH4OH if needed) and add slowly under gentle paddle agitation to avoid localized pH or osmotic shock.
Avoiding Direct Cationic Contact: Because Supragil RM/210-EI is strongly anionic (-SO3- Na+), never mix it directly with cationic quaternary ammonium surfactants or cationic polyamines, which cause immediate electrostatic coacervation and precipitation.
TYPICAL USE LEVELS AND INITIAL FORMULATION APPROACHES FOR SUPRAGIL RM/210-EI
Typical commercial incorporation levels for Supragil RM/210-EI (on an as-supplied dry powder basis) depend on the formulation type, active ingredient hydrophobicity, and particle surface area:
- Agrochemical Water Dispersible Granules (WDG / WG — Extruded, Fluid-Bed, or Spray-Dried): 2.0% to 8.0% w/w (typically 2.5% to 4.5% w/w when paired with 4.0%–6.0% w/w Supragil MNS/90 or MNS/88-E, or 5.0% to 8.0% w/w when used as the primary combined wetting-dispersing system).
- Agrochemical Wettable Powders (WP): 2.0% to 6.0% w/w (typically 3.0% to 5.0% w/w co-milled with technical active ingredient, silica, and kaolin carrier).

- Styrene-Butadiene Rubber (SBR), X-SBR, and Nitrile (NBR) Latex Stabilization: 0.5% to 2.5% phm (parts per hundred dry rubber weight) added as a 15%–25% aqueous solution to prevent mechanical and electrolyte coagulation.
- Aqueous Sulfur, Zinc Oxide, Accelerator (ZDEC/ZDBC), and Antioxidant Dispersions for Latex: 1.5% to 4.5% w/w on total slurry weight (3.0% to 8.0% w/w on dry curative powder weight) in 50%–60% solids ball-milled pastes.
- Aqueous Organic Pigment, Carbon Black, and Textile Disperse/Vat Dye Milling: 3.0% to 15.0% w/w on pigment weight; 15.0% to 50.0% w/w on disperse/vat dye presscake weight; 0.5 to 2.5 g/L in textile dyeing and scouring baths.
- Construction Dry-Mix Mortars, Tile Adhesives, Concrete Admixtures, and Gypsum Slurries: 0.2% to 1.2% w/w on dry binder weight.
- Industrial & Institutional (I&I) Alkaline Cleaners and Anti-Redeposition Baths: 0.5% to 3.5% w/w in concentrate.
The four laboratory and pilot frameworks below illustrate preliminary R&D evaluation protocols for qualified technical personnel.

Slowly atomize 75 to 90 g (15% to 18% w/w) of deionized water onto the powder while kneading for 8 to 10 minutes. Because Supragil RM/210-EI lowers interfacial tension immediately, water distributes uniformly without wet clumping to form a smooth, non-sticky plastic dough. Extrude the dough through a 0.8 mm perforated dome/basket extruder screen.
- Stage 3 (Fluid-Bed Drying and CIPAC QC Testing): Dry the cylindrical extrudates in a laboratory fluid-bed dryer at an inlet air temperature of 60 to 65 °C for 20 minutes until residual moisture is <= 1.2% w/w, and sieve between 0.5 mm and 2.0 mm screens.

COMPATIBILITY AND INCOMPATIBILITY OF SUPRAGIL RM/210-EI
Evaluating chemical and ionic compatibility is essential when formulating Supragil RM/210-EI into multi-component agrochemical, latex, pigment, textile, or construction systems:
- Full Compatibility with Anionic Surfactants and Polymeric Dispersants: Because Supragil RM/210-EI is strongly anionic (-SO3- Na+), it is 100% compatible in all proportions with other anionic surfactants and dispersants—including Supragil MNS/90, Supragil MNS/88-E, Supragil WP, monomeric sodium alkyl naphthalene sulfonates, sodium dioctyl sulfosuccinate (DOSS), linear alkylbenzene sulfonates (LAS), sodium lauryl sulfate (SLS), alpha-olefin sulfonates, phosphate esters, sodium and calcium lignosulfonates, and polycarboxylate / polyacrylate comb polymers (such as Sokalan CP 5).
- Full Compatibility with Nonionic Surfactants, Polymer Latices, and Hydrocolloids: Completely compatible and synergistic with EO-PO block copolymers (poloxamers), fatty alcohol ethoxylates, tristyrylphenol ethoxylates, alkyl polyglucosides (APGs), Styrene-Butadiene Rubber (SBR / X-SBR) latices, Nitrile (NBR) latices, Polychloroprene (CR) latices, Acrylic emulsions, xanthan gum, carboxymethylcellulose (CMC), polyvinyl alcohol (PVA), and bentonite/attapulgite clays.
- Severe Direct Incompatibility with Cationic Surfactants and Quaternary Ammonium Compounds: Never mix Supragil RM/210-EI directly with cationic quaternary ammonium surfactants (such as benzalkonium chloride, cetrimonium bromide, or tallow amine quats), cationic polyamine flocculants, or cationic bitumen emulsions. The negatively charged sulfonate groups (-SO3-) and positively charged quaternary nitrogen ions (+NR4) undergo instantaneous electrostatic ion-pairing (coacervation), precipitating an insoluble, sticky gum that destroys suspension and latex stability.
- High-Electrolyte and Multivalent Cation Limits: While Supragil RM/210-EI tolerates hard water up to 500–1,000 ppm CaCO3 and strong caustic alkalis (NaOH, KOH), adding concentrated divalent or trivalent metal salt solutions (such as > 5%–10% CaCl2, MgCl2, Al2(SO4)3, or FeCl3) will compress the electrical double layer and salt out the surfactant.
- Incompatibility with Strong Oxidizing Agents: Keep dry powder away from concentrated nitric acid, hydrogen peroxide (> 30%), concentrated hypochlorite bleach, chlorates, and permanganates, which oxidize the alkylated naphthalene rings exothermically.
- Compatibility with Plant Materials of Construction: Neutral-to-alkaline (pH 7.5–10.0) solutions and dry powders of Supragil RM/210-EI are non-corrosive to 304 and 316L stainless steel, carbon steel (in alkaline service), HDPE, polypropylene, PVC, glass, EPDM, and NBR elastomers.
SIMILAR PRODUCTS AND ALTERNATIVES TO SUPRAGIL RM/210-EI
When engineering an agrochemical WP, WDG, or SC formulation, an SBR latex compound, or a pigment dispersion, formulators compare Supragil RM/210-EI against pure polymeric methylnaphthalene sulfonate condensates (Supragil MNS/90 and MNS/88-E), pure monomeric dialkylnaphthalene sulfonate wetters (Supragil WP), unsubstituted naphthalene sulfonate condensates (SNF), lignosulfonates, and polycarboxylates.
SUPRAGIL RM/210-EI AND SUPRAGIL MNS/90 OR SUPRAGIL MNS/88-E (PURE POLYMERIC MNS CONDENSATES)
Supragil MNS/90 (~90% active spray-dried powder) and Supragil MNS/88-E (~88% active low-dust micro-granule) are pure formaldehyde condensates of sodium methylnaphthalene sulfonate (CAS 81065-51-2, Mw ~1,800 to 3,800 g/mol).
Because Supragil MNS/90 and MNS/88-E are fully condensed oligomers with 4 to 10 methylene-linked rings, they barely lower the surface tension of water (~58 to 66 mN/m at 1% w/w) and therefore provide weak initial wetting of dry hydrophobic powders on their own, acting strictly as long-term crystal dispersants. By contrast, Supragil RM/210-EI is engineered with an alkyl-substituted (isopropyl/methyl) naphthalene sulfonate architecture that reduces surface tension much more effectively (~38 to 52 mN/m) while retaining strong dispersing and anti-coagulation power. Consequently, Supragil RM/210-EI excels at promoting the rapid opening and wetting of solid-phase active substances in WP and WDG formulations and stabilizing SBR latices, and is frequently combined with Supragil MNS/90 or MNS/88-E for synergistic wetting-plus-dispersion.
SUPRAGIL RM/210-EI AND MONOMERIC SODIUM DIISOPROPYL / DIBUTYL NAPHTHALENE SULFONATES (SUPRAGIL WP / MORWET EFW / NEKAL BX)
Pure monomeric dialkylnaphthalene sulfonates—such as Sodium Diisopropylnaphthalene Sulfonate (Supragil WP, CAS 1322-93-6, MW 314.38 g/mol) and Sodium Dibutylnaphthalene Sulfonate (Nekal BX, CAS 25417-20-3, MW 342.43 g/mol)—are uncondensed single-ring wetting agents.
While pure monomeric wetters drop dynamic surface tension to 30–34 mN/m and wet powders in < 5–10 seconds, they generate higher foam columns during wet bead milling or spray-tank agitation and desorb rapidly from solid crystal surfaces, offering little protection against sedimentation or Ostwald ripening on their own. Supragil RM/210-EI provides a far more balanced, low-foaming wetting-plus-dispersing profile that both opens solid granules/powders in water and stabilizes the resulting suspension against flocculation.
SUPRAGIL RM/210-EI AND UNSUBSTITUTED NAPHTHALENE SULFONATE CONDENSATE (SNF / DISPERSANT NNO)
Unsubstituted Sodium Naphthalene Sulfonate Formaldehyde Condensate (SNF / Dispersant NNO, CAS 9084-06-4) is synthesized from unalkylated naphthalene (C10H8) without methyl or isopropyl alkyl chains.
Because unalkylated SNF lacks aliphatic alkyl groups on the aromatic rings, it exhibits zero wetting power (surface tension ~66–70 mN/m), weaker hydrophobic affinity for low-polarity organic pesticides and SBR polymer droplets, and lower tolerance to hard-water calcium ions (< 300 ppm CaCO3). The alkyl-substituted naphthalene rings of Supragil RM/210-EI deliver rapid solid wetting, stronger adsorption onto hydrophobic actives and SBR latex spheres, and full stability in 500–1,000 ppm CaCO3 hard water.
SUPRAGIL RM/210-EI AND SODIUM / CALCIUM LIGNOSULFONATES
Sodium Lignosulfonate (CAS 8061-51-6) and Calcium Lignosulfonate (CAS 8061-52-7) are natural sulfonated lignin by-products from sulfite wood pulping containing 5% to 20% wood sugars.
Lignosulfonates have dark brown color that stains light powders and latex goods, suffer from botanical batch variability, ferment in liquid storage due to wood sugars, caramelize and turn sticky during high-temperature drying, and provide poor wetting of hydrophobic powders. Synthetic Supragil RM/210-EI is 100% sugar-free, light buff in color, non-fermenting, thermally stable above 220 °C, and provides superior wetting and dispersing power at half the dosage.
SUPRAGIL RM/210-EI AND POLYCARBOXYLATE (PCE) / ACRYLIC COPOLYMER DISPERSANTS
Sodium Polycarboxylate and Acrylic-Maleic Copolymer dispersants (such as Sokalan CP 5 or Geropon TA/72) carry carboxylate groups (-COO- Na+, pKa ~4.5–5.0) along an aliphatic carbon chain.
While polycarboxylates are excellent calcium chelators and crisp WDG binders in neutral/alkaline water, their carboxylate groups protonate and lose charge below pH 5.0, and their hydrophilic aliphatic backbones do not wet hydrophobic powders rapidly. Combining 2.5%–4.0% w/w Supragil RM/210-EI (for fast hydrophobic wetting and aromatic crystal anchoring across pH 1–14) with 1.5%–2.5% w/w Polycarboxylate (for osmotic granule disintegration and Ca2+ chelation) produces superior WDG formulations.

STORAGE AND HANDLING OF SUPRAGIL RM/210-EI
Warehouse Storage Conditions for Supragil RM/210-EI: Store Supragil RM/210-EI (Sodium Alkyl Naphthalene Sulfonate Dispersing and Wetting Agent) in tightly sealed original polyethylene-lined multi-wall paper bags, woven polypropylene bags, or FIBC big bags in a cool, dry, well-ventilated indoor warehouse maintained between 5 and 35 °C away from rain, damp floors, direct sunlight, steam lines, and strong oxidizing agents.
Hygroscopic Moisture Pickup and Caking Prevention for Supragil RM/210-EI: Because spray-dried and micro-granulated alkylnaphthalene sulfonate sodium salts have a high specific surface area and high water affinity, leaving opened bags of Supragil RM/210-EI exposed to ambient relative humidity above 60%–65% will cause moisture absorption and surface crusting or caking. Always twist and seal the inner low-density polyethylene (LDPE) liner bag immediately after partial dispensing, and avoid stacking pallets of Supragil RM/210-EI more than two pallets high in warm warehouses to prevent bottom-bag pressure compaction. Note that if mild physical lumping occurs during extended storage without chemical contamination, the soft lumps crush easily during charging and dissolve completely in water with zero loss of wetting or dispersing performance. When stored unopened in its original moisture-barrier packaging under recommended dry warehouse conditions (< 35 °C), Supragil RM/210-EI has a certified shelf life of 24 to 36 months.
Safe Handling, Dust Control, and Environmental Spill Containment for Supragil RM/210-EI: Handle dry Supragil RM/210-EI at bag-dumping, weighing, and air-jet milling stations equipped with local exhaust ventilation (LEV) to minimize airborne dust. Never dry-sweep spilled Supragil RM/210-EI powder with brooms or compressed air; vacuum spills using an industrial HEPA-filtered vacuum cleaner or damp-shovel into labeled recovery drums, and wash residual floor traces with water (noting that wet surfactant solutions on smooth floors create a slip hazard). Prevent large spills or concentrated washings of Supragil RM/210-EI from entering municipal storm drains or surface watercourses. Strictly segregate Supragil RM/210-EI from strong oxidizing agents and cationic quaternary ammonium compounds.
FIRST AID MEASURES AND SAFETY INFORMATION FOR SUPRAGIL RM/210-EI

FREQUENTLY ASKED QUESTIONS ABOUT SUPRAGIL RM/210-EI
What is Supragil RM/210-EI and how does it function in agrochemical and industrial formulations?
Supragil RM/210-EI is a specialty anionic surfactant, wetting agent, and polymeric dispersing auxiliary based on alkyl-substituted naphthalene sulfonate sodium salt chemistry (CAS 68425-94-5 / 81065-51-2 / 1322-93-6 / 9084-06-4). Supplied as a free-flowing buff powder or water-dispersible micro-granule, it combines lipophilic alkylated (isopropyl/methyl) naphthalene aromatic rings with permanently ionized sodium sulfonate headgroups (-SO3- Na+) to favor the rapid water opening and capillary wetting of hydrophobic solid active substances while imparting a strong negative zeta potential (-40 to -60 mV) that stabilizes aqueous suspensions and polymer latices against flocculation and coagulation.
How does Supragil RM/210-EI differ from Supragil MNS/90 and Supragil MNS/88-E?
Supragil MNS/90 and Supragil MNS/88-E are pure methylated naphthalene sulfonate formaldehyde condensates (CAS 81065-51-2) that barely lower water surface tension (~58 to 66 mN/m) and act strictly as long-term polymeric dispersants. By contrast, Supragil RM/210-EI incorporates an alkylnaphthalene sulfonate architecture (including diisopropyl/methyl naphthalene sulfonate domains) that lowers surface tension much more effectively (~38 to 52 mN/m at 0.5%–1.0% w/w) while maintaining low foaming and strong electrosteric dispersion. Thus, Supragil RM/210-EI acts as a dual-purpose low-foaming wetting, solid-opening, and dispersing agent, and also exhibits specialized stabilizing compatibility with Styrene-Butadiene Rubber (SBR) latices.
Why is Supragil RM/210-EI particularly effective for solid-phase pesticide formulations like WP and WDG?
In Wettable Powders (WP) and Water Dispersible Granules (WDG / WG), hydrophobic technical active ingredients resist initial water entry, causing slow wetting times or undispersed granule cores. Dosing 2.0% to 8.0% w/w of Supragil RM/210-EI lowers the solid-liquid contact angle immediately upon contact with spray water, driving rapid capillary water penetration that splits and opens the solid granule ('spontaneous bloom' in < 15 to 30 seconds) while keeping the released micronized crystals suspended with >= 90%–96% CIPAC MT 184 suspensibility.
Can Supragil RM/210-EI be used in synergy with Supragil MNS/90 or Supragil MNS/88-E in high-load WDG and SC recipes?
Yes. Combining 2.0% to 4.0% w/w Supragil RM/210-EI with 4.0% to 7.0% w/w Supragil MNS/90 or Supragil MNS/88-E (and optionally 1.5% to 2.5% of a polycarboxylate like Sokalan CP 5) is a premier surfactant system for 70%–90% high-load WDG, WP, and SC crop-protection products: Supragil RM/210-EI drives rapid initial wetting and granule opening with minimal foam, while Supragil MNS/90 or MNS/88-E provides multi-ring polymeric anchoring that prevents Ostwald ripening and caking during 54 °C storage.
How does Supragil RM/210-EI prevent coagulation in Styrene-Butadiene Rubber (SBR) and Nitrile (NBR) latices?
In synthetic rubber emulsion polymerization and latex compounding (such as SBR 1502/1500/X-SBR carpet backing, paper coating, foam, and NBR dipped gloves), adding 0.5% to 2.5% phm of Supragil RM/210-EI allows its alkylnaphthalene rings to adsorb onto the polymer latex droplets while its ionized sulfonate groups (-SO3-) reinforce the negative electrical double layer. This prevents mechanical shear coagulation during high-speed pumping and mixing, and prevents calcium/electrolyte shock when mineral fillers or ball-milled sulfur/ZnO/accelerator dispersions are blended into the latex.
How does Supragil RM/210-EI perform in alkaline environments, hard water, and high temperatures?
Because the sulfonate group (-SO3Na) is the salt of a strong sulfonic acid (pKa < -1.5) and contains no hydrolysable ester linkages or temperature-sensitive ethoxylate chains, Supragil RM/210-EI exhibits outstanding solubility and chemical stability in strongly alkaline solutions (pH 8.0 to 14.0) as well as acidic media (pH 1.0 to 7.0), tolerates hard agricultural waters above 500 to 1,000 ppm CaCO3 (CIPAC Standard Waters A, D, and C), has NO thermal cloud point up to > 100 °C, and withstands drying temperatures above 220 to 240 °C without sticky melting.
How is Supragil RM/210-EI used in pigment pastes, textile dyeing, construction admixtures, and alkaline cleaners?
In aqueous pigment pastes and textile disperse/vat dyes (3% to 40% on pigment/dye weight), Supragil RM/210-EI accelerates initial powder wetting in the premix tank and prevents re-agglomeration during bead milling and 130 °C dyeing. In construction dry-mix mortars and concrete admixtures (0.2% to 1.2% w/w), it wets hydrophobic polymer powders and disperses cement/mineral fillers. In alkaline industrial cleaners (0.5% to 3.5% w/w), it suspends particulate soils and pigments in hard water to prevent surface redeposition.
Does Supragil RM/210-EI cause excessive foaming during wet bead milling or field spray-tank mixing?
No. Unlike conventional sodium lauryl sulfate or linear alkylbenzene sulfonate (LAS) wetting agents that build persistent foam columns, the rigid bicyclic alkylnaphthalene structure of Supragil RM/210-EI forms a weakly elastic air-water film that collapses within 30 to 60 seconds (CIPAC MT 47.2 persistent foam after 1 minute <= 5 to 15 mm), ensuring trouble-free horizontal bead milling and field spray-tank agitation.
Is Supragil RM/210-EI approved by the US EPA for food-crop agrochemicals and compliant with EU Annex III co-formulant rules?
Yes. The alkylnaphthalene sulfonate sodium salt and formaldehyde condensate chemistry of Supragil RM/210-EI is approved by the US EPA under 40 CFR 180.910, 180.920, and 180.930 as an inert ingredient for pre- and post-harvest agricultural crop protection with an exemption from tolerance requirements, and is 100% APEO/NPEO-free and compliant with EU Regulation (EC) No 1107/2009 Annex III co-formulant restrictions.
How can agrochemical formulators, latex compounders, and industrial buyers source Supragil RM/210-EI and request COA, TDS, and SDS documents from Ataman Kimya?
Customers can procure Supragil RM/210-EI (CAS 68425-94-5 / 81065-51-2 / 1322-93-6) in moisture-barrier 20 kg and 25 kg polyethylene-lined bags or 500–1,000 kg FIBC big bags—complete with 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.
SUPRAGIL RM/210-EI – TECHNICAL SUMMARY
Supragil RM/210-EI—known in Turkish industrial commerce as Sodyum Alkil Naftalin Sülfonat (Supragil RM/210-EI), Sodyum Diizopropil / Metil Naftalin Sülfonat Kondensatı, Anyonik Zirai İlaç Islatma ve Dispersiyon Ajanı, or SBR Lateks Stabilizatörü, and identified globally under CAS No. 68425-94-5, CAS No. 81065-51-2, CAS No. 1322-93-6, and CAS No. 9084-06-4 (EC No. 614-476-8 / 617-194-3 / 215-343-3)—is a water-soluble, low-foaming anionic surfactant, solid-phase wetting/opening agent, and polymeric dispersing auxiliary with the representative structure (C11H9NaO3S·CH2O)n / C16H19NaO3S (spanning monomeric MW 314.38 g/mol to oligomeric Mw 1,000–4,500 g/mol). Synthesized via the catalytic alkylation and beta-selective sulfonation of naphthalene/methylnaphthalene feedstocks followed by controlled formaldehyde condensation and sodium hydroxide neutralization, this multi-functional amphiphile depresses aqueous surface tension to 38–52 mN/m for rapid capillary powder wetting while anchoring onto hydrophobic crystal faces and polymer latex droplets via pi-pi stacking to generate a strong negative zeta potential (-40 to -60 mV) across pH 1.0 to 14.0.
Supplied as a free-flowing light-tan to buff powder or water-dispersible micro-granule (85.0% to 92.0% active sulfonate content, bulk pour density 440 to 650 g/L, true density 1.38 to 1.55 g/cm3, thermal decomposition > 240 to 300 °C, moisture <= 4.0%–5.0%, and 325-mesh water-insolubles <= 0.05%–0.10%), Supragil RM/210-EI favors the rapid opening, dissolution, and suspension stabilization of hydrophobic solid active ingredients in agrochemical Water Dispersible Granules (WDG / WG), Wettable Powders (WP), Suspension Concentrates (SC), and Suspo-Emulsions (SE). Equally important, Supragil RM/210-EI is fully compatible with Styrene-Butadiene Rubber (SBR), X-SBR, and Nitrile (NBR) latices—preventing mechanical and electrolyte coagulation and stabilizing 55% sulfur/ZnO/accelerator curative dispersions—while also serving as a high-efficiency dispersant in aqueous pigment pastes, 130 °C textile disperse/vat dyeing, construction admixtures, and hard-water alkaline industrial cleaners.
