What is Redispersible Powder?
Hydroxypropyl MethylCellulose is a non-ionic cellulose ether, in the appearance of 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.
