Nzute dị n'etiti hydroxyethyth Cellulose na mkpuchi mmiri

Gịnị bụ Hydroxyethyth Cellulose?
Hydroxyethyl cellulose (HEC), a white or light yellow, odorless, non-toxic fibrous or powdery solid, prepared by etherification reaction of alkaline cellulose and ethylene oxide (or chlorohydrin), belongs to Nonionic soluble cellulose ethers.
