Hydroxypropyl methyl cellulose (HPMC) is a non-ionic polymer, a non-ionic cellulose ether made from natural polymer material cellulose. The product is odorless, tasteless, non-toxic white powder, can be dissolved in cold water to form a transparent viscous solution, with thickening, bonding, dispersing, emulsifying, film-forming, suspending, adsorbing, gelling, surface activity, Features such as moisture retention and protective colloids.
Grade instant HPMC is mainly used in textile chemicals, daily chemical cleaning products, cosmetics and other fields; such as shampoo, body wash, facial cleanser, lotion, cream, gel, toner, hair conditioner, styling products, toothpaste, Saliva, toy bubble water, etc.
The product characteristics of daily chemical grade hydroxypropyl methyl cellulose mainly include:
1. Natural raw materials, low irritation, mild performance, safety and environmental protection;
2. Water-solubility and thickening: it can be dissolved in cold water instantly, soluble in some organic solvents and the mixture of water and organic solvents;
3. Thickening and viscosity-increasing: a small increase in dissolution will form a transparent viscous solution, high transparency, stable performance, solubility changes with 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, relatively stable in aqueous solutions of metal salts or organic electrolytes;
5. Surface activity: the aqueous solution of the product has surface activity, and has the functions and properties of emulsification, protective colloid and relative stability; the surface tension is: 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-retaining effect: the hydrophilic property of HPMC can be added to slurry, paste and pasty products to maintain high water-retaining effect;
8. Thermal gelation: When the aqueous solution is heated to a certain temperature, it becomes opaque until it forms a (poly) flocculation state, which makes the solution lose its viscosity. But after cooling, it will turn into the original solution state again. 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, and a wide range of enzyme resistance, dispersibility and cohesiveness, etc.
