Lintlha tsa tekheniki tsa Hydroxypropyl Methylcellulose
Mona ke tafole e hlalosang lintlha tse ling tse tloaelehileng tsa tekheniki bakeng sa hydroxypropyl methylcellulose (HPMC):
| Thepa | Boleng |
|---|---|
| Sebopeho sa lik'hemik'hale | Motsoako oa cellulose |
| Mokhoa oa limolek'hule | (C6H7O2(OH)xm(OCH3)yn(OCH2CH3)z)n |
| Lethathamo la boima ba limolek'hule | 10,000 - 1,500,000 g / mol |
| Ponahalo | Phofo e tšoeu ho isa ho e tšoeu |
| Solubility | E qhibilihang ka metsing, ha e qhibilihe ka har'a metsoako ea tlhaho |
| Sebaka sa viscosity | 5 - 100,000 mPa·s (ho ipapisitse le kereiti ea viscosity le mahloriso) |
| Mocheso oa mocheso oa gelation | 50 - 90 ° C (ho itšetlehile ka sehlopha sa viscosity le mahloriso) |
| Boemo ba pH | 4.0 - 8.0 (1% tharollo) |
| Mongobo | ≤ 5.0% |
| Likahare tsa molora | ≤ 1.5% |
| Litšepe tse boima | ≤ 20 ppm |
| Meeli ea likokoana-hloko | ≤ 1,000 cfu / g bakeng sa palo eohle ea likokoana-hloko tsa aerobic; ≤ 100 cfu / g bakeng sa tomoso eohle e kopantsoeng le hlobo |
| Li-solvents tse setseng | E lumellana le USP 467 |
| Kabo ea boholo ba karolo | 90% ea likaroloana li ka hare ho 80 - 250 µm |
| Shelf bophelo | Lilemo tse 2-3 ha li bolokiloe sebakeng se phodileng, se omileng |
Ho bohlokoa ho hlokomela hore lintlha tsena tsa tekheniki li ka fapana ho latela sehlopha se ikhethileng le moetsi oa HPMC. Kamehla ho khothaletsoa ho shebana le lintlha tsa sehlahisoa tse fanoeng ke moetsi bakeng sa sehlahisoa se ikhethileng seo u se sebelisang.
