Gabaɗaya Taƙaice

Hydroxypropyl methyl cellulose (HPMC) fari ne zuwa fari, rashin wari, da foda mai gudana. It dissolves conveniently in chilly water to form a clear, zabin danko. 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 kuma 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– daga 5 mPa · s zuwa sama 100,000 mPa · s– gauged a 2% mayar da hankali da 20 ° C. Common qualities consist of 4,000; 15,000; 40,000; kuma 60,000 mPa · s. Thickness directly influences performance in applications like thickening, ɗaure, ko rike ruwa.

Haɗin Sinadari

HPMC is derived from detoxified cellulose, generally from wood pulp or cotton. It includes methoxy teams (19– 30%) da kuma kungiyoyin hydroxypropoxy (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.

Marufi da Ma'ajiya

HPMC is crammed in multi-wall paper bags with internal polyethylene linings. Typical net weights are 10 kg ko 25 kg kowace jaka. Siyayya a cikin yanayi mai kyau, busasshiyar wuri nesa da hasken rana kai tsaye. Keep containers snugly closed to prevent wetness absorption. Service life is normally 24 months under appropriate storage space problems.

Tsaro da Gudanarwa

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.
