Study on prescription technology of Compound Zhizi Gel / 中草药

Objective: To optimize the prescription of Compound Zhizi Gel (CZG) and to optimize the prescription technology of CZG. Methods: Orthogonal test, cold-resistant and heat-resistant tests were used to optimize the prescription technology. Using spreadability, glossiness, evenness, centrifugal stability, and in vitro transdermal diffusion as indexes, other excipients of prescription were optimized. Results: The optimal CZG prescription was Carbopol 940-glycerin-propylene glycol-triethanolamine-azone (1.5%:1.5%:3%:5%:5%). Conclusion: The optimized prescription is reliable and stable. It could meet the production requirements of CZG.
