Description
Hydroxyethyl Cellulose(HEC) Product Description
HEC is a non-ionic, water-soluble polymer derived from cellulose through a series of chemical and physical processes.
Appearance of HEC
HEC is a white to light yellowish, oderless and tastless powder, readily soluble in hot or cold water to form a viscous gel solution. When pH in solution is within 2 to 12, the solution is quite stable.
Characteristic of HEC
Since HEC group is nonionic one in water solution, it won't be reacted with other anions or cations and insensitive to the salts. But HEC molecule is capable of generating esterification, etherification and reaction, so it is possible to make it insoluble in water or improve its properties. HEC also has good film-forming ability and surface activity.
