Description

Polyglyceryl-4 Oleate is a non-ionic, biodegradable surfactant derived from natural glycerin and oleic acid. This versatile compound is valued for its excellent emulsifying, solubilizing, and conditioning properties, making it a key ingredient in formulations requiring mildness and stability. It is primarily used by manufacturers in the personal care, cosmetics, and food industries to create stable, high-quality emulsions and to improve product texture and skin feel.

Application

• Personal Care & Cosmetics: Acts as a primary or co-emulsifier in creams, lotions, and sunscreens, providing stable oil-in-water emulsions and a smooth, non-greasy skin feel.
• Food Industry: Used as a food emulsifier (E475) in baked goods, margarines, and whipped toppings to improve texture, volume, and shelf life.
• Pharmaceuticals: Serves as an excipient in topical ointments and creams, enhancing drug delivery and formulation stability.
• Industrial Applications: Functions as a lubricant, anti-static agent, or emulsifier in textile processing, metalworking fluids, and agricultural formulations.
• Household & I&I Cleaning: Employed in liquid soaps, detergents, and hard-surface cleaners for its surfactant and degreasing properties.
