Stearic Acid Polyoxyethylene Ether SG-10 (CAS No.: 9004-99-3), chemical name Polyoxyethylene (10) Stearate, has a molecular structure containing hydrophilic polyoxyethylene segments and lipophilic stearate groups, giving it excellent emulsifying, wetting, and dispersing capabilities. As a non-ionic surfactant, it exhibits good chemical stability against acids, bases, and hard water, and has good compatibility with various anionic, cationic, and non-ionic surfactants. This characteristic makes it an indispensable functional component in many industrial formulations.
This product is particularly prominent in the cosmetics field. As an efficient O/W emulsifier, it can uniformly disperse oily components in the water phase, forming a stable and fine cream or emulsion texture, while also providing mild cleansing effects. In the textile printing and dyeing industry, it can be used as a leveling agent (promoting uniform dye uptake, preventing color spots and streaks), a softening agent (imparting soft and smooth hand feel to fabrics), an antistatic agent, and a soaping agent. In industrial cleaning and household detergents, SG-10 significantly enhances the emulsification, dispersion, and removal of oil stains.
Additionally, SG-10 has mature process applications in metalworking fluids (emulsified cutting fluids, rust-proof fluids), pesticide emulsifiable concentrate formulations, emulsion polymerization (acrylate, styrene-acrylic systems, etc.), leather chemicals (fatting agents, degreasing agents), and water-based paint dispersion. The product has excellent safety performance: acute oral toxicity is low-toxic (rat LD50 > 5,000 mg/kg), 5% dilution is non-irritating to skin, no sensitization or genetic toxicity, and is easily biodegradable, with a 28-day degradation rate exceeding 60%, in compliance with environmental regulations.
