IHydroxypropyl Methylcellulose idatha yobugcisa
Nantsi itheyibhile echaza idatha yobugcisa eqhelekileyo ye-hydroxypropyl methylcellulose (HPMC):
| Ipropati | Ixabiso |
|---|---|
| Ubume beMichiza | I-cellulose derivative |
| Ifomula yemolekyuli | (C6H7O2(OH)xm(OCH3)yn(OCH2CH3)z)n |
| Uluhlu lobunzima bemolekyuli | 10,000 - 1,500,000 g / mol |
| Imbonakalo | Umgubo omhlophe ukuya kumhlophe |
| Ukunyibilika | Inyibilika emanzini, ayinyibiliki kwizinyibilikisi eziphilayo |
| Uluhlu lweViscosity | 5 – 100,000 mPa·s (kuxhomekeke kwibakala le-viscosity kunye nokugxila) |
| Uluhlu lobushushu beGelation | 50 - 90 ° C (kuxhomekeke kwibakala le-viscosity kunye nokugxila) |
| Uluhlu lwe-pH | 4.0 - 8.0 (1% isisombululo) |
| Umxholo wokufuma | ≤ 5.0% |
| Umxholo wothuthu | ≤ 1.5% |
| Iintsimbi ezinzima | ≤ 20 ppm |
| Imida yeMicrobial | ≤ 1,000 cfu/g kubalo lulonke lwe-aerobic microbial; ≤ I-100 cfu / g ye-yeasts edibeneyo kunye nokubumba |
| Izinyibilikisi ezishiyekileyo | Ihambelana ne-USP 467 |
| Ukuhanjiswa kobungakanani besuntswana | I-90% yamasuntswana angaphakathi kwama-80 – 250 µm |
| Beka ubomi kwishelufa | Iminyaka emi-2-3 xa igcinwe kwindawo epholileyo neyomileyo |
Kubalulekile ukuqaphela ukuba ezi data zobugcisa zinokwahluka ngokuxhomekeke kwibakala elithile kunye nomvelisi we-HPMC. Kuhlala kucetyiswa ukuba udibane nenkcazo yemveliso ebonelelwa ngumenzi wemveliso ethile oyisebenzisayo.
