HPMC powder is a highly pure cotton cellulose as raw material, under alkaline conditions by special etherification and preparation.White or whitish powder. HPMC powder decreases with the decrease of methoxide content, increase of gel point, decrease of water solubility and decrease of surface activity. Description: Hebei Yibang Building Materials Co., Ltd.’s hpmc powder can be dissolved in some organic solvents and water-organic solvent mixed solvents. It does not have gelling properties when heated. Hpmc powder is a kind of cotton and wood raw material that is non-toxic to humans. Hpmc powder is hygroscopic when dry, but stable. Its solution is stable at pH 3-11. As the temperature increases, the viscosity of the solution decreases. Heating and cooling can reversibly transform the Hpmc powder from a solution state to a gel state. According to different grades and concentrations, the gelation temperature is 50~90℃. Hpmc powder has anti-enzyme effect as an aqueous solution and maintains good viscosity stability during long-term storage. However, its aqueous solution is susceptible to microbial attack, so preservatives should be added during storage. When Hpmc powder is used as a thickener for eye drops, benzalkonium chloride is usually added as a preservative. Basic Info Model NO.
