Hydroxyethyl cellulose (HEC) is a white or pale yellow, tasteless, non-toxic fibrous or powdered solid, prepared by alkaline cellulose and ethylene oxide (or chloroethanol) by etherification, belongs to non-ionic soluble cellulose ethers.
HEC has been widely used in oil exploitation, coating, paint, construction, medicine and food, textile, paper making and polymer polymerization, due to its good thickening, suspension, dispersion, emulsification, bonding, film formation, water protection and providing protective colloids.40 Visual screening rate 99%;
