Stearic Acid Polyoxyethylene Ether SG-10, with the chemical name Polyoxyethylene (10) Stearate (CAS No.: 9004-99-3), also known as Emulsifier SG-10, PEG-10 Stearate, etc. Its molecular structure contains hydrophilic polyoxyethylene chain segments (10 EO units) and lipophilic stearate groups, belonging to a typical nonionic surfactant. The appearance is usually a pale yellow paste to solid.
This product is manufactured by Hai'an Guoli Chemical Co., Ltd., and is one of the basic varieties in the domestic nonionic surfactant field. With a rational balance of hydrophilic-lipophilic groups in the structure, SG-10 exhibits excellent chemical stability in acidic, alkaline, and hard water media, and has good compatibility with various anionic, cationic, and nonionic surfactants, making it a highly versatile surfactant raw material.
In terms of safety, SG-10 is classified as a low-toxicity substance (acute oral LD50 in rats > 5,000 mg/kg), non-irritating to skin, only mildly and reversibly irritating to eyes, with no sensitization or genotoxicity observed. It is also readily biodegradable (degradation rate >60% in 28 days under OECD 301B), meeting environmental regulatory requirements.

SG-10 has a wide range of application fields, mainly covering the following areas:
1. Cosmetics and personal care products: As an efficient O/W emulsifier, it is used in creams, lotions, makeup removers, cleansing creams, etc., where it uniformly disperses oily components in the water phase, forming a stable and fine texture, imparting good spreadability and skin feel to the products.
2. Textile dyeing and finishing auxiliaries: It can be used as a leveling agent (to prevent uneven dyeing and streaks), softener (to impart a soft and smooth hand feel to fabrics), antistatic agent (to reduce fiber surface resistance), and soaping agent (to remove loose color and improve color fastness), making it a fundamental raw material in the textile auxiliary field.
3. Industrial and household detergents: In heavy-duty formulas such as metal cleaning and equipment cleaning, it enhances the emulsifying and dispersing ability for oily soils; in laundry detergents and dishwashing liquids, it acts as a co-emulsifier and detergency booster.
4. Metalworking fluids: As an emulsifier and stabilizer in emulsion-type cutting fluids, it helps form a stable working fluid from base oil and water; it can also be used in rust preventive systems to help distribute rust inhibitors evenly.
5. Pesticide emulsifiers and emulsion polymerization: It serves as a core emulsifying component in pesticide emulsifiable concentrate formulations and as an emulsion stabilizer during the polymerization of acrylate, styrene-acrylic, and other emulsions, ensuring particle size uniformity and storage stability.
