Specification of hydroxypropyl methyl cellulose hpmc

Hydroxypropyl Methyl Cellulose (HPMC)– Ngwaahịa chọrọ

Nchịkọta izugbe

Hydroxypropyl methyl cellulose (HPMC) bụ ocha na-acha ọcha, enweghị isi, and free-flowing powder. It dissolves conveniently in chilly water to form a clear, nhọrọ viscous. HPMC is non-ionic and steady over a broad pH range (usually 3– 11). It does not sustain microbial growth and shows outstanding film-forming capability.

Key Physical Residences

The look of HPMC is a fine, granular powder. Its mass density generally drops in between 0.28 na 0.40 g/mL. The wetness content remains below 5% when kept appropriately. Fragment dimension goes through a 20-mesh screen (100% preserved on 80-mesh prevails). Ash content remains under 1.5%.

Thickness Qualities

HPMC can be found in several viscosity qualities– sitere na 5 mPa · s gafere 100,000 mPa · s– tụrụ na 2% lekwasị anya na 20 Celsius C. Àgwà ndị nkịtị mejupụtara 4,000; 15,000; 40,000; na 60,000 mPa · s. Thickness directly influences performance in applications like thickening, njide, or water retention.

Ngwakọta kemịkalụ

HPMC is derived from detoxified cellulose, generally from wood pulp or cotton. It includes methoxy teams (19– 30%) and hydroxypropoxy groups (4– 12%). These alternatives offer HPMC its unique solubility and thermal gelation properties. The item meets pharmacopeial standards such as USP/NF, EP, and JP when intended for pharmaceutical usage.

Nkwakọ ngwaahịa na Nchekwa

HPMC is crammed in multi-wall paper bags with internal polyethylene linings. Typical net weights are 10 n'arọ ma ọ bụ 25 n'arọ kwa akpa. Zụrụ ahịa n'ụdị ejiji, ebe kpọrọ nkụ dị anya site na ìhè anyanwụ kwụ ọtọ. Keep containers snugly closed to prevent wetness absorption. Service life is normally 24 ọnwa n'okpuru kwesịrị ekwesị nchekwa ohere nsogbu.

Nchekwa na njikwa

HPMC is safe and generally identified as risk-free (GRAS) for food and pharmaceutical usage. Use standard dust control steps throughout managing to avoid breathing. Use handwear covers and eye defense as a preventative measure. Prevent developing air-borne dirt.
