求助增溶剂和乳化剂，需毒性及刺激性小，谢谢？以下是FDA指导原则中的内容： When Lecithin, NF, a surfactant, is used in MDI formulations, additional acceptance criteria and tests controlling the complete compositional profile should be used (e.g., levels of phosphatidyl choline, phosphatidyl ethanolamine, phosphatidyl inositol, lysophosphatidyl choline, phosphatidic acid, triglycerides, fatty acids, carbohydrates). When Oleic Acid, NF is used as a surfactant in MDI formulations, additional specifications should be included for identification, assay, and for characterization and control of the compositional profile of impurities (e.g., individual specified fatty acids, unknowns). 磷脂和油酸都可用作气雾剂中的表面活性剂，不过质量要求很严格，你得先看看，是否有吸入制剂用的批文。目前世界上比较有名的磷脂生产厂家是：德国的lipoid公司和日本的丘比公司，lipoid国内代理商是上海东尚，丘比的国内代理商是上海艾伟特，油酸他们也有，你可以问问他们。查看更多
