Description

Glyceryl Dihydroxystearate is a versatile, non-ionic surfactant and emulsifier derived from glycerin and hydroxystearic acid. This compound is valued for its excellent skin compatibility, thickening properties, and ability to stabilize emulsions in demanding formulations. It is a critical ingredient for manufacturers in the personal care, cosmetics, and pharmaceutical industries seeking to create stable, luxurious, and high-performance products. Its unique structure provides both emulsifying and consistency-giving effects.

Application

• Primary emulsifier and co-emulsifier in cosmetic and pharmaceutical creams and lotions.
• Viscosity modifier and thickener for water-in-oil (W/O) and oil-in-water (O/W) emulsions.
• Key ingredient in sun care products, decorative cosmetics, and antiperspirant sticks for stabilization.
• Used in hair care conditioners and treatments to provide conditioning and emollient properties.
• Acts as a dispersing agent and consistency factor in pigment pastes and makeup products.
• Formulation aid in topical pharmaceutical preparations for controlled release and texture.
• Base material for creating specialty esters with customized melting points and functionalities.
