Product Description

Features:

 

Hydroxypropyl methylcellulose (HPMC) is a synthetic nonionic cellulose derivative and one of the derivatives of hydroxymethylcellulose (HMC). It is prepared by reacting cellulose with chlorinated acrylates and methyl chlorides. HPMC is dissolved in water to form a transparent colloidal solution with excellent adhesion, stability and rheology, so it is widely used in building materials, medicine, cosmetics, food and other fields.
75HDCR is a kind of special hydroxypropyl methylcellulose specially designed to be used as hydrophilic gel framework material. The hydrophilic gel framework drug release system has many advantages:
1.Wide applicability, no risk of cross-linking reaction, no interaction, high stability
2.The drug release rate is relatively stable, with small individual differances
3.Excellent compressibility, wettability, and other characteristics
