Controlled Release Grade Hydroxypropyl Methyl Cellulose for Hydrophilic Gel Sustained Release Agent
Basic information:
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

Application:
Hydroxypropyl methylcellulose (HPMC) has a variety of uses, including but not limited to the following:
Building materials: In building materials, HPMC is commonly used as a binder, thickener and modifier of cement mortar, helping to improve the cohesiveness, fluidity and water resistance of the material.
Pharmaceutical field: In pharmaceutical preparations, HPMC is commonly used as a sustained release agent, stabilizer and coating agent, which is used to regulate the release speed of drugs and improve taste.
Cosmetics: In cosmetics, HPMC is commonly used as a thickener, emulsifier and stabilizer to help improve the texture and stability of products.
Food industry: In food processing, HPMC is commonly used as a thickener and stabilizer to improve the taste and texture of food.
Overall, HPMC is a multifunctional chemical, which is widely used in construction materials, medicine, cosmetics and food, and has important industrial and commercial value.
