Hydroxyethyl cellulose
Synonyms: HEC
CAS No.: 9004-62-0
Molecular Formula:C29H52O21
Properties: HEC is a white, free-flowing granular powder, prepared from the alkali cellulose and ethylene oxide (or ethylene chlorohydrin) by etherification, and belongs to non-ionic soluble cellulose ethers, both soluble in hot and cold water. Owing to good thickening, suspending, dispersing, emulsifying, film-forming, water-protecting and providing protective colloid properties,
