Description

Polyglyceryl-3 Dioleate is a non-ionic, biodegradable surfactant and emulsifier derived from natural glycerin and oleic acid. This versatile compound is valued for its excellent solubilizing, stabilizing, and skin-conditioning properties, making it a key functional ingredient in high-performance formulations. It is primarily used by manufacturers in the personal care, cosmetics, and food industries seeking effective, mild, and multifunctional additives.

Application

• Personal Care & Cosmetics: Acts as a primary emulsifier and co-emulsifier in creams, lotions, and sunscreens, providing stable oil-in-water emulsions with a smooth, non-greasy skin feel.
• Food Industry: Functions as a food-grade emulsifier (E475) in baked goods, margarines, and whipped toppings to improve texture, volume, and shelf stability.
• Pharmaceuticals: Used as an excipient in topical ointments and creams for its emulsifying and solubilizing capabilities, aiding in drug delivery.
• Industrial Applications: Serves as a lubricant, anti-static agent, and processing aid in textile, plastic, and metalworking formulations.
• Household & I&I Cleaning: Employed in liquid soaps, detergents, and fabric softeners for its surfactant properties and mildness.
