Hydroxypropyl Methyl Cellulose (HPMC)– Drug Grade Specifications

Basic Summary

Hydroxypropyl Methyl Cellulose (HPMC) he ma ki waho-ma, kakara-kore, and free-flowing powder. It is made from all-natural cellulose through chemical treatment. This product fulfills rigorous top quality standards for usage in pharmaceutical applications.

Trick Physical Residences

HPMC dissolves easily in cool water yet does not dissolve in warm water or most organic solvents. When combined with cold water, it develops a clear to a little gloomy thick option. The viscosity of the service depends upon the grade utilized. Regular thickness ranges from 5 mPa · s to over 100,000 mPa · s i 20 ° C. Ko te pH o a 2% liquid service normally drops between 5.0 a 8.0.

Hangahanga matū

The chemical framework includes methoxy (– OCH ₃) and hydroxypropoxy (– OCH TWO CHOHCH ₃) groups attached to the cellulose backbone. The normal substitution degrees are:
– Ko te ihirangi paetukutuku Methoxy: 19% ki 30%.
– Rauemi Hydroxypropoxy: 4% ki 32%.

These worths might vary a little based upon the details grade required for different medication formulations.

Te Pure me te Haumaru

Pharmaceutical-grade HPMC satisfies the needs of major pharmacopeias, including USP-NF, Ph. Eur., me JP. It has extremely low degrees of contaminations. Heavy metals are limited to not greater than 10 ppm. Recurring solvents and microbial contamination are purely regulated. Overall cardiovascular microbial matter stays below 100 CFU/g, and it has to be free from defined pathogens like Escherichia coli a Salmonella.

Puka hua me te waahi rokiroki

HPMC is crammed in secured, moisture-resistant containers, usually multi-layer paper bags with internal polyethylene liners. Hokona i roto i te hauhautanga, te waahi maroke rawa atu i te ra tika. Keep the container tightly near prevent moisture uptake, which can affect performance. Effectively kept, it remains stable for as much as 24 marama.
