Cold water instant hydroxypropyl methyl cellulose (HPMC) :
English name: Hydroxypropyl methyl cellulose (HPMC)
Common aliases: instant thickener, stable thickener, emulsion stabilizer, dispersion thickener, antifreeze thickener, Instant fiber.
Main ingredients and chemical structure: nonionic cellulose ether made from natural polymer cellulose.
Origin brand: Hebei Yulan
Product Introduction: Yulan Hydroxypropyl Methylcellulose (HPMC) is a non-ionic polymer, a non-ionic cellulose ether made from natural polymer material cellulose. This product is an odorless, tasteless, non-toxic self-colored powder that can be dissolved in cold water to form a transparent viscous solution. It has the functions of thickening, bonding, dispersing, emulsifying, film-forming, suspending, adsorbing, gelling, and surface activity. , moisture retention and protective colloid properties.
Yulan daily chemical grade instant hydroxypropyl methylcellulose (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, mouthwash, toy bubble water, etc.
Product features of Yulan daily chemical grade instant hydroxypropyl methylcellulose (HPMC):
(1). Natural raw materials, low irritation, mild performance, safe and environmentally friendly;
(2). Water solubility and thickening: can be quickly dissolved in cold water, soluble in some organic solvents and mixtures of water and organic solvents;
(3). Thickening and viscosity: After a small amount of dissolution, a transparent viscous solution is formed, with high transparency and stable performance. The solubility changes with the viscosity. The lower the viscosity, the greater the solubility; effectively improving 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 and properties of emulsification, protective colloid and relative stability; the surface tension is: 42~56dyn/cm for 2% aqueous solution;
(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, pasty, 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 a (polymer) flocculation state is formed, 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;
(10). The viscosity time of Yulan daily chemical grade hydroxypropyl methylcellulose in tap water at room temperature is 3 minutes, and the viscosity time in purified water will be slower, about 30 minutes, so that there is enough Short working time, convenient viscosity control and easy application.
