Description

Polyglyceryl-4 Pentastearate is a non-ionic, multifunctional surfactant and emulsifier derived from polyglycerol and stearic acid. This compound is valued for its excellent stabilizing and texturizing properties, making it a key ingredient in formulations requiring consistent performance and stability. It is primarily used by manufacturers in the cosmetics, personal care, and food industries to create stable emulsions and improve product texture.

Application

• Primary emulsifier and stabilizer in cosmetic creams, lotions, and sunscreens.
• Texture modifier and viscosity enhancer in hair care products and conditioners.
• Food-grade emulsifier for bakery products, margarines, and whipped toppings.
• Co-emulsifier in pharmaceutical ointments and topical delivery systems.
• Key ingredient in decorative cosmetics for pigment dispersion and smooth application.
• Stabilizing agent in industrial lubricants and release agents.
