Overview
Description

Hydroxypropyl methylcellulose (HPMC) is a non-ionic cellulose ether made of natural polymer material cellulose through a series of etherification. It is an odorless, tasteless and nontoxic white powder that swells in cold water to a clear or slightly hazy colloidal solution. Hydroxypropyl methylcellulose is partly substituted by o-methyl group and partly substituted by o-2-hydroxypropyl group, and is divided into different grades because of different viscosity and degree of substitution. It has the characteristics of thickening, dispersing, emulsification, film-forming, suspension, adsorption, surface activity, water retention and protective colloid.

Features

Reversible gelation upon heating; Surface active and enzyme resistant; Pseudoplasticity

Application

Emulsifiers, Thickeners and Suspending Agents;For the development of controlled release drugs.;Binders, lubricants, steric stabilizers and water retention aids
