Description

Polyglyceryl-3 Triisostearate is a non-ionic, lipophilic surfactant and emollient ester derived from polyglycerol and isostearic acid. This compound is highly valued for its excellent skin compatibility, emulsifying properties, and ability to provide a rich, non-greasy feel in formulations. It is a critical ingredient for manufacturers in the personal care, cosmetics, and pharmaceutical industries seeking to create stable, high-quality emulsions and texture-enhancing products.

Application

• Primary Emulsifier in water-in-oil (W/O) creams, lotions, and sun care products.
• Co-emulsifier and Stabilizer in oil-in-water (O/W) systems to enhance emulsion texture and stability.
• Skin Care Actives Carrier for improved delivery and penetration of lipophilic active ingredients.
• Viscosity Modifier and Thickening Agent in anhydrous formulations like sticks, balms, and ointments.
• Conditioning Agent in hair care products such as conditioners and hair masks to impart softness and manageability.
• Make-up Formulations, including foundations, lipsticks, and mascaras, for pigment dispersion and smooth application.
• Pharmaceutical Ointments and topical delivery systems as a non-irritating base ingredient.
