| Abstract
|
| [Objective] To research the rheological characteristcs of Carbopol 981 for providing a conference in its preparation.[Methods] The viscosity of carbopol were measured under different conditions by Brookfield DV-Ⅲ ULTRA Rheometer.Through contrasting with Carbopol 934,the rheological characteristics of Carbopol 981 was deeply explored.[Results] Carbopol 981 was proved to be a false plastic fluid.It was more sensitive to pH change,ion concentration and mechanic shearing.[Conclusion] Carbopol 981 has better tolerance to temperature,ion concentration and mechanic shearing than Carbopol 934.These rheological data would be referred to choose suitable condition in the pharmaceutical preparation. |
