Hydroxyethyl cellulose(HEC) is a gelling and thickening agent derived from cellulose. HEC is non-ionic, water-soluble materials that provide good properties of thickening, suspending, binding, emulsify, film-forming, stabilize, disperse, retain water and etc. And It is widely used in coatings, construction, medicine, food, papermaking and polymer polymerization industry. In medicine field, Hydroxyethyl cellulose and methyl cellulose(MHEC) are frequently used with hydrophobic drugs in capsule formulations, to improve the drugs' dissolution in the gastrointestinal fluids.

Cosmate HEC,is a cellulose etherified with hydroxyethyl groups to give the desired properties,is a nonionic water-soluble polymer,is a white,free-flowing granular powder.It's insoluble in organic solvents,but it is ealisy dispersed in cold and hot water to give solution of varying viscosities.
