Hydroxypropyl ሜቲል ሴሉሎስ (HPMC)– የምርት መስፈርቶች

General Summary

Hydroxypropyl ሜቲል ሴሉሎስ (HPMC) ከነጭ ወደ ውጪ-ነጭ ነው።, ሽታ የሌለው, and free-flowing powder. ግልፅ ለማድረግ በቀዝቃዛ ውሃ ውስጥ በተመጣጣኝ ሁኔታ ይሟሟል, viscous አማራጭ. 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 እና 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– ጀምሮ 5 mPa · s እስከ በላይ 100,000 mPa · s– የሚለካው በ 2% ትኩረት እና 20 ° ሴ. Common qualities consist of 4,000; 15,000; 40,000; እና 60,000 mPa · s. Thickness directly influences performance in applications like thickening, ማሰር, or water retention.

የኬሚካል ቅንብር

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, ኢ.ፒ, and JP when intended for pharmaceutical usage.

የምርት ማሸግ እና ማከማቻ

HPMC is crammed in multi-wall paper bags with internal polyethylene linings. Typical net weights are 10 ኪ.ግ ወይም 25 ኪ.ግ በከረጢት. በሚያምር ሁኔታ ይግዙ, ከፀሐይ ብርሃን የራቀ ደረቅ ቦታ. Keep containers snugly closed to prevent wetness absorption. Service life is normally 24 በተገቢው የማከማቻ ቦታ ችግሮች ውስጥ ወራት.

ደህንነት እና አያያዝ

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.
