1. Natural raw materials, low irritation, mild performance, safety and environmental protection;
2. Water solubility and thickening: it can quickly dissolve in cold water, dissolve in some organic solvents and the mixed liquid of water and organic solvents;
3. Thickening and viscosity increasing: a small amount of increase in dissolution will form a transparent viscous solution with high transparency and stable performance. The solubility changes with the viscosity. The lower the viscosity, the greater the solubility; effectively improve the flow stability of the system;
4. Salt resistance: HPMC is a non-ionic polymer, which is relatively stable in aqueous solutions of metal salts or organic electrolytes;
5. Surface activity: The aqueous solution of the product has surface activity, has the functions and properties of emulsification, protective colloid and relative stability; surface tension: 2% aqueous solution is 42~56dyn/cm;
6. PH stability: the viscosity of the aqueous solution is stable within the range of PH3.0-11.0;
7. Water retention: HPMC’s hydrophilic properties can be added to paste, paste, and paste products to maintain high water retention;
8. Thermal gelation: When the aqueous solution is heated to a certain temperature, it becomes opaque until it becomes flocculated, causing the solution to lose its viscosity. But after cooling, it will be transformed into the original solution state. The temperature at which the gel phenomenon occurs depends on the type of product, the concentration of the solution and the heating rate;
9. Other characteristics: excellent film-forming properties, as well as a wide range of enzyme resistance, dispersibility and adhesion characteristics.
