Specification of hydroxypropyl methyl cellulose hpmc

Hydroxypropyl Methyl Cellulose (HPMC)– Tulaga Manaomia

Aotelega Lautele

Hydroxypropyl methyl cellulose (HPMC) e pa'epa'e e pa'epa'e, leai se manogi, and free-flowing powder. It dissolves conveniently in chilly water to form a clear, filifiliga 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 ma 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– amata mai 5 mPa · s i luga 100,000 mPa · s– fuaina i 2% focus and 20 °C. Common qualities consist of 4,000; 15,000; 40,000; ma 60,000 mPa · s. Thickness directly influences performance in applications like thickening, noatia, or water retention.

Fuafuaga Fa'a-Kemikolo

HPMC is derived from detoxified cellulose, generally from wood pulp or cotton. It includes methoxy teams (19– 30%) ma vaega 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.

afifiina oloa ma Teuina

HPMC is crammed in multi-wall paper bags with internal polyethylene linings. Typical net weights are 10 kg po o 25 kilokalama i le taga. Fa'atau i se fa'atauga, nofoaga matutu mamao mai le la sa'o. Keep containers snugly closed to prevent wetness absorption. Service life is normally 24 masina i lalo o faʻafitauli talafeagai avanoa avanoa.

Puipuiga ma le Taulimaina

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.
