Tilmaamaha Hydroxypropyl Methyl Cellulose HPMC

Hydroxypropyl Methyl Cellulose (HPMC)– Tilmaamaha Alaabta

Chemical Identity

Hydroxypropyl Methyl Cellulose (HPMC) waa semi-synthetic, polymer-ka biyaha ku milma oo laga sameeyay cellulose. It appears as a white to beige powder. The material has no odor and is non-toxic. HPMC satisfies food, dawooyinka, and industrial grade standards.

Deganaanshaha Jireed

The powder flows easily and dissolves conveniently in cool water. It forms a clear to slightly over cast thick remedy. HPMC does not liquify in warm water above 70 ° C but will gel when heated up. As soon as cooled, it redissolves. Dhumucdiisu waxay u dhaxaysaa 5 mPa · s to over 100,000 mPa · s, ku tiirsanaanta tayada.

Pureness and Structure

Regular HPMC consists of:
– Methoxy groups: 19%– 30%.
– Hydroxypropoxy groups: 4%– 32%.
– Waxa ku jira qoyan: ≤ 5%.
– Shabkada dambaska ah: ≤ 1.5%.
– pH (2% xal): 4.0– 8.0.

Hefty metals and microbial limits comply with pertinent pharmacopeial demands (tusaale., USP/NF, EP, JP).

Functional Performance

HPMC waxay si fiican u shaqeysaa sidii dhumuc ahaan, xidhe, movie previous, iyo wakiilka biyaha-haynta. In construction products like floor tile adhesives and provides, it aids maintain water in the mix much longer, enhancing workability and attachment. Daawooyinka, it controls drug launch and functions as a tablet binder. In cuntada, it stabilizes solutions and enhances appearance.

Kaydinta iyo Maaraynta

Ku kaydi HPMC si cajiib ah, meel qalalan oo ka fog qoyaanka. Maintain containers securely shut. The service life is generally 24 months when saved correctly. Avoid call with strong oxidizing representatives. Use common industrial health practices throughout handling.
