Hydroxypropyl Methylcellulose data teknụzụ
Nke a bụ tebụl na-akọwapụta ụfọdụ data teknụzụ a na-ahụkarị maka hydroxypropyl methylcellulose (HPMC):
| Ngwongwo | Uru |
|---|---|
| Ọdịdị chemical | Mwepụta nke cellulose |
| Usoro ihe omimi | (C6H7O2(OH)xm(OCH3)yn(OCH2CH3)z)n |
| Oke ịdị arọ molekụla | 10,000 - 1,500,000 g / mol |
| Ọdịdị | Na-acha ọcha na-acha ọcha ntụ ntụ |
| Solubility | Soluble na mmiri, insoluble na organic solvents |
| Oke viscosity | 5 - 100,000 mPa·s (dabere na ọkwa viscosity na itinye uche) |
| Gelation okpomọkụ nso | 50-90C (dabere na viscosity ọkwa na itinye uche) |
| oke pH | 4.0 - 8.0 (1% ngwọta) |
| Ọdịnaya nke mmiri | ≤5.0% |
| ntụ ọdịnaya | ≤1.5% |
| Ọla dị arọ | ≤20 ppm |
| Oke microbial | ≤ 1,000 cfu/g maka mkpokọta ikuku microbial ọnụ; ≤ 100 cfu/g maka ngụkọta yists na ebu |
| Ihe mgbaze fọdụrụnụ | Na-akwado USP 467 |
| Nkesa nha urughuru | 90% nke ụmụ irighiri ihe dị n'ime 80-250 µm |
