Hydroxyethyl Cellulose, commonly abbreviated as HEC, is a non-ionic, water-soluble polymer derived from cellulose. It is a white to off-white powder in form. Hydroxyethyl Cellulose is widely used in cosmetics, personal care, and industrial formulations as a thickening, gelling, and film-forming agent. It dissolves readily in both hot and cold water to produce clear, stable viscous solutions, making it a highly versatile rheology modifier. In personal care applications, it is commonly found in shampoos, conditioners, lotions, creams, and liquid soaps. In industrial and household cleaning formulations, Hydroxyethyl Cellulose is valued for its ability to build viscosity and improve the suspension of active ingredients. It also provides excellent compatibility with a wide range of surfactants, salts, and other formulation components.
