Introdution
-
HEC is a white or light yellow odorless, tasteless and easy-flowing powder. As a non-ionic surfactant, hydroxyethyl cellulose has thickening, suspending, bonding, floating, filming, dispersion, and water retention In addition to providing protective colloids, it also has the following properties:
-
HEC is soluble in hot or cold water, and does not precipitate at high temperature or boiling, so that it has a wide range of solubility and viscosity characteristics, and non-thermal gelling;
-
It is non-ionic and can coexist with a wide range of other water-soluble polymers, surfactants, and salts. It contains high-concentration electrolyte solutions.
-
The water retention capacity is twice that of methyl cellulose, and it has better flow regulation.
-
Compared with the recognized methylcellulose and hydroxypropyl methylcellulose, the dispersing ability of HEC is poor, but it has strong protective colloid ability. Uses: Generally used as a thickener, protective agent, adhesive, stabilizer, and additives for preparing emulsions, gels, ointments, lotions, eye clearing agents, suppositories and tablets, and also used as hydrophilic gels and skeletons Materials, preparation of matrix-type sustained-release preparations, and can also be used as stabilizers in food.
