Description

Peg-40 Lanolin, Polyoxyethylene (40) Lanolin is a non-ionic surfactant and emulsifier derived from the ethoxylation of lanolin, creating a water-soluble derivative with excellent skin-conditioning properties. This chemical is valued for its ability to form stable emulsions, enhance skin feel, and improve the solubility of active ingredients in aqueous systems. It is a critical raw material for formulators in the cosmetics, personal care, and pharmaceutical industries, where mildness, performance, and regulatory compliance are paramount.

Application

• Cosmetic & Personal Care Formulations: Acts as a primary emulsifier, solubilizer, and skin-conditioning agent in creams, lotions, shampoos, and makeup products.
• Pharmaceutical Topicals: Used in ointments, medicated creams, and dermatological preparations for its emulsifying and soothing properties.
• Hair Care Products: Functions as a conditioning agent and emulsifier in conditioners, hair masks, and styling products to improve manageability and shine.
• Baby Care Products: Incorporated into diaper rash creams, baby lotions, and washes for its mildness and skin-protective qualities.
• Sun Care and Suncare Products: Helps stabilize and emulsify sunscreen formulations while contributing to a non-greasy skin feel.
• Industrial Emulsions: Serves as an emulsifier and lubricant in specialty industrial applications, including textile and leather processing.
