Description

Steareth-2 Phosphate is a non-ionic surfactant phosphate ester, widely recognized for its excellent emulsifying, dispersing, and solubilizing properties. This compound is particularly valued for its ability to create stable oil-in-water emulsions and enhance the performance of formulations under a wide range of pH conditions. It serves as a critical functional ingredient for manufacturers in the cosmetics, personal care, and pharmaceutical industries, where consistent quality and reliable performance are paramount.

Application

• Primary Emulsifier in cosmetic creams, lotions, and sun care products.
• Stabilizing Agent for pharmaceutical ointments and topical delivery systems.
• Dispersant and Wetting Agent in agrochemical formulations and industrial cleaners.
• Co-emulsifier in combination with other surfactants to enhance emulsion stability and texture.
• Key ingredient in mild, sulfate-free cleansing products and baby care formulations.
• Processing Aid in textile and leather treatment chemicals.
