HPMC Hydroxypropyl Methyl Cellulose is a non-ionic cellulose ether, white powder, odorless and tasteless. It is soluble in water, most polar organic solvents, and the appropriate proportion of ethanol/water, propanol /water and dichloroethane, but insoluble in diethyl ether, acetone, and anhydrous alcohol. In cold water, it will swell into a clear or slightly turbid colloidal solution.
Its aqueous solution has surface activity, high transparency and stable properties.
HPMC Hydroxypropyl MethylCellulose from PTAMADMIXTURE mfg has thermal gelation properties, so after heating the aqueous solution will precipitate and form gels, and dissolve again after cooling. Products of different specifications have different gelling temperatures. Its solubility varies with the viscosity, and the lower the viscosity is, the greater the solubility will be. There are some differences in the properties of Hydroxypropyl MethylCellulose of different specifications. The dissolution of HPMC Hydroxypropyl MethylCellulose in water is not affected by the pH value.
