摘　　要：为解决杀螺胺乙醇胺盐可湿性粉剂使用过程中絮凝、变色问题,通过试验筛选润湿分散剂等进行组合优化,确定了91%杀螺胺乙醇胺盐的可湿性粉剂的最佳配方:杀螺胺乙醇胺盐原药91%,分散剂SD-819为1%、SD-720为5.5%,润湿剂wet-88为0.5%,抗絮凝剂三聚磷酸钠1%,白炭黑为填料补足。结果表明,所得制剂无絮凝变色,热贮稳定且悬浮率大于90%,,各项指标均符合可湿性粉剂质量要求。In order to solve the problem of flocculation and discoloration in using the niclosamide ethanolamine salt wettable powder, we optimized the formulation of the wettable powder. The optimum is as follow, 91% niclosamide ethanolamine, 1% SD-819, 5.5% SD-720,0.5% wet-88, 1% sodium tripolyphosphate, carbon-white filled up. The results show that the resulting preparation has no flocculation with heat storage stability and suspension rate greater than 90%. All the indicators are in line with the quality requirements of WP.
