Trick Physical and Chemical Residences

HPMC is a non-ionic cellulose ether made from natural cellulose. It liquifies easily in chilly water yet does not dissolve in hot water over its gelation temperature level. The product creates clear, anemic services with excellent film-forming ability.

Typical viscosity varieties from 5 mPa · s pikeun 100,000 mPa · s (ditangtukeun dina 2% konsentrasi, 20 ° C), ngandelkeun peunteun. Wetness content stays below 5% (ku beurat). pH a 2% remedy normally falls in between 4.0 jeung 8.0.

Pureness and Top Quality Standards

This HPMC fulfills pharmacopeial criteria such as USP-NF, EP, and JP when made use of in pharmaceutical applications. For industrial or building uses, it complies with appropriate technological requirements. Hefty metals are kept under 10 ppm. Residue on ignition stays below 1.5%. Microbial limits comply with basic guidelines: overall cardio count ≤ 100 CFU/g, yeast and mold and mildew ≤ 10 CFU/g, and absence of E. coli jeung Salmonella.
