Description

Polyglyceryl-4 Tristearate is a non-ionic, multifunctional emulsifier and stabilizer derived from glycerol and stearic acid. This compound is valued for its ability to create stable emulsions and modify texture in complex formulations, ensuring consistent product performance. It is primarily needed by manufacturers in the cosmetics, personal care, and food industries seeking reliable, high-quality ingredients for creams, lotions, and food-grade applications.

Application

• Primary emulsifier and co-emulsifier in cosmetic and personal care formulations such as creams, lotions, and ointments.
• Stabilizer and texture modifier in food products, contributing to smooth mouthfeel and consistent structure.
• Key ingredient in pharmaceutical ointments and topical preparations for its emulsifying properties.
• Used in industrial applications as a lubricant and release agent in various manufacturing processes.
• Functions as a dispersing agent for pigments and powders in color cosmetics and makeup products.
• Improves the stability and shelf-life of water-in-oil (W/O) and oil-in-water (O/W) emulsion systems.
