Polyglyceryl-3 Cetyl Ether

What is Polyglyceryl-3 Cetyl Ether?

Polyglyceryl-3 Cetyl Ether is a non-ionic ingredient formed by combining polyglycerol-3, derived from glycerol, with cetyl alcohol from natural fatty sources like coconut or palm. Commonly found in cleansers, shampoos, lotions, and creams, it functions by decreasing surface tension at the interface of oil and water phases. This action creates stable emulsions, ensuring products have uniform consistency, easy spreadability, and thorough rinsability. Its ether structure provides gentleness, making it ideal for formulations targeting everyday cleansing and hydration without stripping the skin's natural barrier. Often used in natural or sensitive skin lines, it supports clear, residue-free results in micellar waters and body washes.
