Role of hydroxyethyl cellulose

Important properties: Hydroxyethyl cellulose as a non-ionic surfactant, in addition to a thickening, suspending, adhesive, emulsified, film, dispersion, water and provide protective colloid action, but also has the following properties: 1, HEC is soluble in hot or cold water, generally insoluble in most organic solvent; hot or boiling does not precipitate, it has a wide range of solubility and viscosity characteristics, and non-thermal gelation; 2, itself Other non-ionic water-soluble polymer with a wide range of surfactants, salt coexistence, is an excellent colloid thickener containing a high concentration of the electrolyte; 3, water retention capacity than a methyl cellulose times, with better regulation of the flow, 4, HEC recognized the dispersion capacity compared with methyl cellulose and hydroxypropyl methyl cellulose dispersion capacity worst, but the strongest protective colloid.
