HPMC Hydroxypropyl Methyl Cellulose
HPMC
Hydroxypropyl Methyl Cellulose is odorless, tasteless,non-toxic cellulose ethers produce from natural high molecular cellulose through series of chemical processing and chieved.It is white powder with good water solubility. It has thickening, adhesion ,dispersing, emulsifying, film, suspended, adsorption, gel, and protective colloid properties of surface activity and maintain moisture function properties ect.
Function: Thickening,dispersing, emulsifying, film forming and tableting excipients.
2.Application
