Cold water instant hydroxypropyl methylcellulose (HPMC) English name: Hydroxypropyl methyl cellulose (HPMC) Common aliases: instant thickener, stable thickener, emulsion stabilizer, dispersion thickener, antifreeze thickener, Instant cellulose.
Main components and chemical structure: non-ionic cellulose ether made from natural polymer cellulose.
Product Introduction: Chuangyao Hydroxypropyl Methyl Cellulose (HPMC) is a non-ionic polymer, a non-ionic cellulose ether made from natural polymer material cellulose. The product is an odorless, tasteless, non-toxic self-coloring powder, which can be dissolved in cold water to form a transparent viscous solution with thickening, bonding, dispersing, emulsifying, film-forming, suspending, adsorbing, gelling, and surface active , Moisture retention and protective colloid properties.
Daily chemical grade instant hydroxypropyl methylcellulose 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, skin care Hair conditioner, styling products, toothpaste, saliva, toy bubble water, etc.
Product characteristics of daily chemical grade instant hydroxypropyl methylcellulose HPMC:
1. Natural raw materials, low irritation, mild performance, safety and environmental protection;
2. Water solubility and thickening property: it can be dissolved in cold water, dissolved in some organic solvents and the mixture of water and organic solvents;
3. Thickening and viscosity-increasing: a small increase will form a transparent viscous solution after dissolution, 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, so that the solution loses 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, as well as a wide range of enzyme resistance, dispersibility and cohesiveness;
10. The viscosity starting time of daily chemical grade hydroxypropyl methylcellulose in tap water at normal temperature is 3 minutes, and the viscosity starting time in pure water will be slower, about 30 minutes, so that there is enough work Time, easy to control viscosity, easy to apply.
