Description

D-Glucitol Triisooctadecanoate is a high-purity, non-ionic surfactant and emollient ester derived from sorbitol and stearic acid. This compound is valued for its excellent skin-feel properties, stability, and ability to function as a solubilizer and co-emulsifier in demanding formulations. It is primarily sought by manufacturers in the personal care, cosmetics, and pharmaceutical industries for creating luxurious creams, lotions, sunscreens, and topical ointments.

Application

• Cosmetic & Personal Care Formulations: Acts as a premium emollient and skin-conditioning agent in creams, lotions, and sun care products.
• Pharmaceutical Topicals: Used as a solubilizer and stabilizer in ointments, gels, and transdermal drug delivery systems.
• High-Performance Emulsions: Serves as a co-emulsifier and viscosity modifier in water-in-oil (W/O) and oil-in-water (O/W) emulsion systems.
• Color Cosmetics: Provides smooth application and enhanced pigment dispersion in foundations, lipsticks, and makeup products.
• Hair Care Products: Imparts conditioning and lubricity in hair serums, conditioners, and styling creams.
• Industrial Lubricants & Release Agents: Functions as a biodegradable lubricant component and mold release agent in specialized applications.
