HPMC
HPMC is odorless, tasteless,non-toxic cellulose ethers producted from natural high molecular
cellulose through series of chemical processing and achieved.It is white powder with good water
solubility. It has thickening, adhesion ,dispersing, emulsifying, film, suspended, adsorption, gel,
and protetive colloid properties of surface activity and maintain moisture function properties ect.
