Hydroxyethyl cellulose
It is a non-ionic water-soluble polymer, white or slightly yellow, easy-flowing powder, odorless and tasteless, soluble in both cold water and hot water, and the dissolution rate increases with the increase of temperature. Insoluble in organic solvents.
Properties of hydroxyethyl cellulose:
1. HEO is soluble in hot or cold water, and does not precipitate at high temperature or boiling, so it has a wide range of solubility and viscosity characteristics, as well as non-thermal gelation.
2. The non-ionic itself can coexist with a wide range of other water-soluble polymers, surfactants and salts, and is an excellent colloidal thickener for high-concentration electrolyte solutions.
3. The water retention capacity is twice as high as that of methyl cellulose, and it has better flow regulation.
4. Compared with the recognized methyl cellulose and hydroxypropyl methyl cellulose, the dispersing ability of HEC is the worst, but the protective colloid ability is the strongest.
