Hydroxyethyl Cellulose
Hydroxyethyl cellulose (HEC) polymer is a hydroxyethyl ether of cellulose, obtained by treating cellulose with Sodium Hydroxide and reacting with ethylene oxide. HEC polymers are largely used as water-binder and thickening agent in many industry applications, that is, personal care products, pharmaceutical formulations, building materials, adhesives, etc., and as stabilizer for liquid soaps. They are available as white free-flowing granular powders that easily dissolve in cold and hot water to give transparent solutions with varying viscosities depending on polymer concentration, type and temperature.
