摘  要:以起始外观、冷藏[(0±2)℃,7d]外观、热贮[(54±2)℃,14d]外观和稀释稳定性(1∶200倍液)合格和流动性好为标准,通过对不同表面活性剂、助剂、助溶剂、水的配方筛选,得到20%氰戊菊酯微乳剂的最佳制剂配方为:氰戊菊酯20%,丁醇-二甲苯(1∶1)用量20%,乳化剂为农乳500^#-602^#p,用量18%,水余量.该微乳剂经(54±2)℃贮存14 d,平均分解率为1.0%;0~5℃贮存12个月,经时稳定性合格.The text introduced the consisting and preparation method of microemulsion for 20% fenvalerate. According to the standard of transparent appearance of initial preparation cold storage [ (0 ± 2) ℃, 7 d], heat storage [ (54 + 2) ℃, 14 d] and eligible dilution stability( 1:200 fluid) and good mobility, we have carried out the screening tests recipes of 20% fenvalerate microemulsion using different surfactants, solvents,co-solvents and water. Screening tests recipes: fenvalerate 20% ;butyl alcohol and xylene (1: 1) 20% ;emulsifying agent (500^#-602^#p) 18% ;water else. Heat storaged 14 d at (54±:2) ℃ ,decomposed rate less than 1.0% ;cold storaged 12 months at 0 -5 ℃ ,the of long-term stability is good.
