Product introduction:

 

Hydroxypropyl methyl cellulose (HPMC) is a kind of non-ionic polymer. It is a kind of non-ionic cellulose ether which is made from cellulose. The product is odorless, tasteless, non-toxic self colored powder, which can be dissolved in cold water to form a transparent viscous solution. It has the characteristics of thickening, adhesion, dispersion, emulsification, film-forming, suspension, adsorption, gelation, surface activity, water retention and colloid protection.

 

Quick-solving Daily Chemicals hydroxypropyl methylcellulose (HPMC) is mainly used in textile chemicals, cosmetic washing products, cosmetics and other fields; shampoo, liquid soap, cleansing cream, emulsion, cream, gel, toner, conditioner, stereotypes, toothpaste, saliva, toy bubble water, etc.

 

Product features:

 

1. Natural raw materials, low irritation, mild performance, safety and environmental protection;

 

2. Water solubility and thickening: it can be quickly dissolved in cold water, in some organic solvents and in the mixture of water and organic solvents;

 

3. Thickening and viscidity: a small amount of solution is dissolved to 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 the aqueous solution of metal salt or organic electrolyte;

 

5. Surface activity: the aqueous solution of the product has surface activity, emulsifying, protecting colloid and relative stability; the surface tension is 42 ~ 56 dyn / cm for 2% aqueous solution;

 

6. PH stability: the viscosity of aqueous solution is stable in the range of ph3.0-11.0;

 

7. Water retention: the hydrophilic property of HPMC can maintain high water retention when added to paste, paste and paste products;

 

8. Thermal gelation: when the water solution is heated to a certain temperature, it becomes opaque until it forms (polymerizes) flocculation state, making the solution lose viscosity. But it will change to the original solution state after cooling. The temperature of gelation depends on the type of product, the concentration of solution and the rate of heating.

 

9. Other characteristics: excellent film-forming properties, as well as a wide range of enzyme resistance, dispersion and adhesion characteristics
