CAS 9004-62-0 Hydroxyethyl cellulose in Stock

Hydroxyethyl cellulose (HEC), chemical formula (C2H6O2)n, is a white or light yellow, odorless, non-toxic fibrous or powdered solid, prepared by etherification reaction of alkaline cellulose and ethylene oxide (or chloroethanol), and is a non-ionic soluble cellulose ether. Due to its good thickening, suspension, dispersion, emulsification, adhesion, film formation, moisture protection and protective colloid properties, HEC has been widely used in oil extraction, coatings, construction, medicine and food, textiles, papermaking, and polymer polymerization.
