Preparation of Peppermint Oil Sustained Microcpasules by Intra-Liquid Desiccation
Abstract:
Objective: Peppermint oil sustained microcapsules were prepared by intra-liquid desiccation. Methods: The orthogonal design methods were used to get the optimal prescription by uesing ethyl cellulose as materials and sodium dodecyl sulfate as emlsifier. Results: The best prescription of peppermint oil sustained microcapsules were as follows: 0.1mL peppermint oil, ethyl cellulose : drug was 10:1, sodium dodecyl sulfate was 0.11 g, ethyl acetate was 16 mL, distilled water was 260 mL. Conclusion: The method was simple and easy to be controlled, reproducibility was good.
