Brève introduction :
Hydroxypropyl methyl cellulose (HPMC) is a non-ionic cellulose ether made from natural polymer material – refined cotton, after a series of chemical processing. Hydroxypropyl methylcellulose (HPMC) is an odorless, tasteless, nontoxic, self-coloring powder. It is soluble in cold water to form a transparent and viscous solution, and has the properties of thickening, adhesion, dispersion, emulsification, film formation, suspension, adsorption, gelation, surface activity, moisturizing and protective colloid.
