Superiority:

Hydroxyethyl cellulose (HEC) is a non-ionic, water-soluble polymer derived from cellulose through a series of chemical and physical processes. 

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. 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 acetal 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.

The viscosity changes little in the range of pH 2-12, but the viscosity decreases beyond this range. It has the properties of thickening, suspending, bonding, emulsifying, dispersing, retaining moisture and protecting colloids. Solutions of different viscosity ranges can be prepared. It is unstable under normal temperature and pressure, avoids humidity, heat, high temperature, and has excellent salt solubility to the dielectric. The aqueous solution is allowed to contain a high concentration of salts and is stable.
