Description

Polyoxy(Methyl-1,2-Ethanediyl), .Alpha.-Hydro-.Omega.-Hydroxy-, Octadecyl Ether is a high-purity, non-ionic surfactant belonging to the polyoxyethylene alkyl ether family, specifically with a C18 (stearyl) chain. This compound is valued for its excellent emulsifying, dispersing, and wetting properties, making it a critical performance additive in demanding formulations. It is primarily sought after by manufacturers in the personal care, cosmetics, pharmaceuticals, and industrial cleaning sectors who require reliable and consistent raw materials for stable emulsions and effective surface activity. The product is supplied under strict quality control to ensure batch-to-batch uniformity for your production processes.

Application

• Cosmetics & Personal Care: Acts as a primary emulsifier and stabilizer in creams, lotions, and ointments, providing a smooth texture and enhancing product shelf life.
• Pharmaceuticals: Used in topical drug delivery systems as an emulsifying agent for creams and as a solubilizer for active pharmaceutical ingredients (APIs).
• Industrial & Institutional Cleaning: Serves as a key surfactant in heavy-duty degreasers, metal cleaners, and textile processing aids due to its effective wetting and oil-emulsifying capabilities.
• Agrochemical Formulations: Employed as an emulsifier and dispersant in pesticide and herbicide concentrates to improve sprayability and target adhesion.
• Paints & Coatings: Functions as a pigment dispersant and grinding aid, improving color development and stability in water-based systems.
• Textile Processing: Utilized as a lubricant, softener, and dye-leveling agent in various stages of fabric manufacturing.
