Hydroxyethylcellulose (HEC, Cosmetic Grade)
CAS Number: 9004-62-0
Hydroxyethylcellulose (HEC) is a non-ionic, water-soluble cellulose ether widely used as a thickener, rheology modifier, and film former in personal care formulations. Unlike carbomers, HEC does not require neutralization and is effective across a wide pH range (2–12). It provides pseudoplastic flow behavior, good compatibility with electrolytes, and film-forming properties for hair and skin care applications.
