Hydroxypropyl methylcellulose (HPMC) is a nonionic polymer, a nonionic cellulose ether made from natural polymer material cellulose. This product is an odorless, tasteless, non-toxic white powder that can be dissolved in cold water to form a transparent viscous solution. It has the functions of thickening, binding, dispersing, emulsifying, film-forming, suspending, adsorbing, gelling, and surface activity. Moisture retaining and protective colloid properties. Daily chemical grade instant HPMC is mainly used in textile chemicals, daily chemical washing products, cosmetics and other fields; such as shampoo, body wash, facial cleanser, lotion, cream, gel, toner, conditioner, styling products, toothpaste , sip water, toy bubble water, etc.
The main product characteristics of Yulan daily chemical grade hydroxypropyl methylcellulose are:
(1). Natural raw materials, low irritation, mild performance, safe and environmentally friendly;
(2). Water solubility and thickening properties: It can be quickly dissolved in cold water, soluble in some organic solvents and mixtures of water and organic solvents;
(3).Thickening and viscosity properties: After a small amount of addition, it will form a transparent viscous solution with high transparency. Stable performance, solubility changes with viscosity, the lower the viscosity, the greater the solubility; effectively improves the flow stability of the system;
(4). Salt resistance: HPMC is a non-ionic polymer and is 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 of emulsification, protective colloid and relative stability. The 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-retaining effect: The hydrophilic property of HPMC can be added to slurry, paste, and pasty products to maintain high water-retaining effect;
(8). Thermal gelling effect: When the aqueous solution is heated to a certain temperature, it becomes opaque until it forms (polymer). ) flocculation state, causing the solution to lose its viscosity. But after cooling, it will return to its original solution state. The temperature at which gelation 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, dispersion and adhesion properties.
