Hidroksipropil Metil Selulosa (HPMC)– Rekisitonan di Produkto

Resumen General

Hidroksipropil metil selulosa (HPMC) ta un blanku pa blanku-off, sin holó, and free-flowing powder. E ta disolvé konvenientemente den awa friu pa forma un kla, opshon viskoso. HPMC is non-ionic and steady over a broad pH range (normalmente 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 i 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– ku ta varia di 5 mPa · s to over 100,000 mPa · s– midi na 2% enfoká i 20 ° C. Common qualities consist of 4,000; 15,000; 40,000; i 60,000 mPa · s. Thickness directly influences performance in applications like thickening, marashon, or water retention.

Komposishon Kímiko

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.

Empaketamentu i Almasenamentu di produkto

HPMC is crammed in multi-wall paper bags with internal polyethylene linings. Typical net weights are 10 kg òf 25 kg per bag. Hasi kompra den un kaminda di moda, área seku leu for di lus di solo. Keep containers snugly closed to prevent wetness absorption. Service life is normally 24 months under appropriate storage space problems.

Seguridat i Maneho

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.
