Gidroksipropil metil tsellyuloza (HPMC)– Mahsulotga qo'yiladigan talablar

Umumiy xulosa

Gidroksipropil metil tsellyuloza (HPMC) oqdan oppoq ranggacha, hidsiz, and free-flowing powder. It dissolves conveniently in chilly water to form a clear, yopishqoq variant. 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 va 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– gacha 5 mPa · s dan ortiq 100,000 mPa · s– da o'lchanadi 2% diqqat va 20 ° C. Umumiy sifatlar quyidagilardan iborat 4,000; 15,000; 40,000; va 60,000 mPa · s. Thickness directly influences performance in applications like thickening, bog'lash, yoki suvni ushlab turish.

Kimyoviy tarkibi

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.

Mahsulotni qadoqlash va saqlash

HPMC is crammed in multi-wall paper bags with internal polyethylene linings. Typical net weights are 10 kg yoki 25 har bir sumka uchun kg. Modada xarid qiling, to'g'ridan-to'g'ri quyosh nuri tushmaydigan quruq joy. Keep containers snugly closed to prevent wetness absorption. Service life is normally 24 tegishli saqlash joyi muammolari ostida oylar.

Xavfsizlik va ishlov berish

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.
