Hydroxypropyl methyl cellulose is a non-ionic cellulose ether polymer, according to the replacement level of substituent groups as well as the modification of the different levels have different solubility, surface activity, and with the role of thermal gelation the compatibility of other substances, thereby expanding its fields of application.
Their characteristics as follows:1 Surfactant to provide surface activity in solution to achieve the required emulsion and protective colloid, as well as phase stability.
2 PH stability, PH - broad range of (PH: 3 ~ 11).
3 Water retention after absorbing water in their porous surface, you can retain water.
4 Bonding can be used as the color, tobacco products, paper, adhesives, etc., with excellent features, can also be used to paint
5 A better anti-enzyme anti-enzyme capacity, long-term storage stability of viscosity when the good.
6 Prevent precipitation of suspended solids out, and thus inhibit the formation of sediment.
7 Emulsion ------ a result of reduced surface and interfacial tension, as well as thickening the water phase, they can be a stable emulsion.
