PEG-Crosspolymer

PEG / Ethoxylated

What is PEG-Crosspolymer?

PEG-Crosspolymer is a synthetic, high-molecular-weight polymer derived from polyethylene glycol, created through the polymerization of ethylene oxide followed by cross-linking to form a stable, three-dimensional network. This structure allows it to absorb water and swell, making it ideal for use in skincare emulsions, gels, serums, sunscreens, and makeup products. In formulations, it acts by increasing viscosity to prevent separation and dripping, ensuring even distribution of active ingredients. Additionally, it deposits a sheer, breathable film on the skin or hair surface, enhancing product longevity, water repellency, and smooth feel without greasiness. Commonly incorporated at low levels, it supports diverse textures from lightweight lotions to rich creams, improving overall user experience in daily cosmetic routines.
