Description

Polyoxy(Methyl-1,2-Ethanediyl), .Alpha.-Hydro-.Omega.-Hydroxy-, Ether With D-Glucitol (6:1) is a non-ionic surfactant and emulsifier belonging to the class of sorbitan ethoxylates, specifically a polyoxyethylene sorbitan derivative. This compound is valued for its excellent solubilizing, wetting, and stabilizing properties in complex formulations. It is a critical ingredient for manufacturers in the pharmaceutical, cosmetic, and food industries, where consistent performance and regulatory compliance are paramount. Its versatility makes it essential for creating stable emulsions and enhancing the bioavailability of active ingredients.

Application

• Pharmaceutical Formulations: Used as a solubilizer and emulsifier in oral, topical, and injectable drug products to improve the dissolution of poorly water-soluble active pharmaceutical ingredients (APIs).
• Cosmetics & Personal Care: Acts as a key surfactant and emulsifying agent in creams, lotions, shampoos, and makeup, providing stability and a smooth texture.
• Food Industry (as permitted): Employed as an emulsifier and dispersant in food products, baked goods, and edible coatings to ensure uniform texture and prevent separation.
• Industrial Applications: Serves as a wetting agent, dispersant, and stabilizer in agrochemicals, paints, coatings, and textile processing chemicals.
• Laboratory & Biotechnology: Utilized in cell culture media and biochemical research as a non-ionic detergent for membrane protein solubilization.
