The chemical name of emulsifier MOA-3B is Fatty Alcohol Polyoxyethylene (3) Ether (INCI name: Laureth-3), belonging to the category of nonionic surfactants. The product appears as a colorless to slightly yellow transparent liquid, produced by Hai'an Guoli Chemical Co., Ltd. Due to its molecular structure containing only 3 ethylene oxide (EO) units, its hydrophilic-lipophilic balance (HLB) value leans toward the lipophilic end, making it particularly suitable for preparing water-in-oil (W/O) emulsion systems.
This product exhibits excellent chemical stability, maintaining good performance in both acidic and alkaline environments, and has outstanding tolerance to hard water, without precipitating or losing efficacy due to high concentrations of calcium and magnesium ions. The product has high active content and purity, with a near-neutral pH value, making it relatively mild to substrates and operators, thus serving as a highly versatile industrial surfactant.
With its moderate lipophilic characteristics and multifunctional emulsifying and dispersing capabilities, MOA-3B is widely used in many industrial fields such as pesticide emulsifiable concentrate formulations, chemical fiber oils, textile printing and dyeing auxiliaries, industrial mold release lubricants, emulsion polymerization stabilizers, and oil-soluble system dispersants, making it one of the core additives of choice for formulators in oil-based or solvent-based systems.

Pesticide Formulations: As a core emulsifying component in pesticide emulsifiable concentrate (EC) systems, it enables the active ingredient to self-emulsify into a stable emulsion upon dilution, ensuring uniform spray application and enhancing field efficacy.
Chemical Fiber Industry: Used in synthetic fiber spinning oils for emulsification, lubrication, and bundling, reducing friction between fibers and metal parts, minimizing static buildup, and improving spinnability.
Textile Printing and Dyeing: Acts as a leveling agent and antistatic agent, promoting uniform dye uptake, preventing streaks and spots, while imparting antistatic properties to fiber surfaces.
Industrial Mold Release: Applied to mold surfaces to form a release film, effectively reducing adhesion between the product and mold, achieving clean release and protecting the mold.
Emulsion Polymerization: Provides micellar nucleation sites and stabilizes latex particles during emulsion polymerization, preventing gelation or coagulation, ensuring storage stability of the latex product.
Oil-Soluble Systems: Facilitates uniform dispersion of solid particles, pigments, or active ingredients in oil-based or solvent-based formulations, preventing agglomeration and sedimentation.
