Hydroxypropyl Methylcellulose faʻamatalaga faʻapitoa

Hydroxypropyl Methylcellulose faʻamatalaga faʻapitoa

Ole laulau lea o lo'o fa'amatalaina ai nisi fa'amatalaga fa'apitoa masani mo le hydroxypropyl methylcellulose (HPMC):

Meatotino Taua
Fa'asologa o vaila'au Cellulose e maua mai
fua mole (C6H7O2(OH)xm(OCH3)yn(OCH2CH3)z)n
Fuafuaga mamafa molekala 10,000 – 1,500,000 g/mol
Fa'aaliga Pa'epa'e i le pa'epa'e pa'epa'e
Solubility Solu i le vai, e le mafai ona solu i solu organic
Viscosity laina 5 – 100,000 mPa·s (fa'alagolago i le viscosity grade ma le fa'atonuga)
Va'aiga vevela gelation 50 – 90°C (fa'alagolago i le viscosity grade ma le fa'atonuga)
pH va'aiga 4.0 – 8.0 (1% fofo)
Susū i totonu ≤ 5.0%
mea efuefu ≤ 1.5%
Metala mamafa ≤ 20 ppm
tapula'a microbial ≤ 1,000 cfu/g mo le faitau aofa'i ole microbial aerobic; ≤ 100 cfu/g mo le aofa'i fa'afefete tu'ufa'atasi ma fa'ameamea
Soli totoe Fa'atasi ma le USP 467
Tufatufaina o le lapopoa 90% o vaega o lo'o i totonu ole 80 – 250 µm
Ola fa'asa 2-3 tausaga pe a teuina i se nofoaga malulu ma mago

E taua le maitauina o nei faʻamatalaga faʻapitoa e mafai ona fesuisuiaʻi e faʻatatau i le vasega maʻoti ma le gaosiga o le HPMC. E fautuaina i taimi uma e faʻafesoʻotaʻi faʻamatalaga o oloa na tuʻuina atu e le kamupanī mo le oloa faʻapitoa o loʻo e faʻaaogaina.
