Glycereth-7-Triacetate
What is Glycereth-7-Triacetate?
Glycereth-7-Triacetate is a synthetic derivative of glycerol, a simple polyol obtained from vegetable or synthetic sources, modified by ethoxylation with seven ethylene oxide units followed by acetylation with acetic acid to form a triester. This creates a low-viscosity, water-miscible liquid widely incorporated into cosmetic products like lotions, gels, and serums within the emollient and solvent categories. Functionally, it lubricates the skin surface to enhance slip and smoothness, reduces evaporation of water from formulations, and solubilizes both polar and non-polar substances, enabling stable emulsions and uniform delivery of actives. Its hydrophilic nature supports hydration without greasiness, improving product spreadability and sensory appeal in daily skincare routines.
