It can dissolve in other cool or hot water. Normally, it does not dissolve in organic
solvents. Viscosity change is small when pH value is within 2 to 12 but decrease
when pH value is low than the range.
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
Applications:
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.
Packing, transportation and storage:
20kg or 25kg/PE bag or barrel with inner liners
Keep dry in ventilated places and keep away from sunshine during transportation
