Description
As a non ionic surface-active agent, it possesses the following
characteristics in addition to acts of thicker agent, suspending
agent, adhesive agent, emulsification agent, coating agent, water
keeping agent and protective agent.
1. HEC can dissolve in both cool and hot water while it does not
deposit when in hot or boiling water showing large range of
non-gelatin capacity.
2. Because of non-ionic base, it can be coexist with other
water-soluble polymizers, surface-active agent and salts.
3. Water keeping ability is twice that of Methyl Cellulose
(MC)showing good flowage adjusting ability.
4.It is stable in viscosity and anti-mildew and makes coatings good
open can effect ion as well as excellent floating-plain
effects.
IV . Application:
HEC is mainly used as adhesive protective gelatin, thicker agent
and stabilizing agent as well as additives to make emulsion, frozen
gelatin, lotion, eye clear agent, suppository and tablets. HEC is
also used for hydrophilic colloid, framework. Material, ready-made
framework controlled release agent, and stabilizing agent in
foodstuff.
It is also used in paint and coatings,oil feild and cosmetic.
