摘　　要：[目的]乳油使用较多有机溶剂,而水基性剂型中微乳剂和可溶液剂使用较多极性溶剂作溶剂或助溶剂,在安全和环保性上受到人们质疑。论述水基性无溶剂液体剂型的提出、开发的依据及其优点。这种液体剂型不使用任何（极性和非极性）溶剂和植物油溶剂,研制出一种全新的水基性无溶剂2.5%高效氯氟氰菊酯透明液体剂型。[结果]经研制,其最佳配方：高效氯氟氰菊酯2.5%,乳化剂（烷基酚聚氧乙烯醚,烷基酚聚氧乙烯醚磷酸酯）12%~15%,助表面活性剂（丁醇）5%,防冻剂（丙二醇）2%,水余量。该配方样品为无色透明液体,经冷贮[（0±1）℃,7 d]和热贮[（54±2）℃,14 d]高效氯氟氰菊酯分解率小于2%。[结论]样品经测定各项指标符合有关要求,毒力测定结果与传统微乳剂相同。原料成本仅为同剂量乳油40%、传统微乳剂的72%、生物柴油作溶剂微乳剂的77%。[Aims]EC uses much solvent,and water-based ME and SL use much solvent flux（polar solvent）,which receives question in the safety and the environmental protection.The water-based solvent-free liquid formulation proposal,development basis and merit were described in the article.This kind of liquid formulation does not use any（polar and nonpolar） solvent and vegetable oil solvent.One kind of brand-new water-based solvent-free λ-cyhalothrin 2.5% transparent liquid formulation was developed.[Results] The optimum ratio was as follow： λ-cyhalothrin 2.5%,emulsifier（alkylphenol ethoxylates,alkylphenol ethoxylates phosphate）12-15%,cosurfactant（butyl alcohol）5%,antifreeze（propylene glycol）2% and water remainder after research.This formula sample was colourless transparent liquid,after stored coldly [（0±1） °c,7 d] and stored hotly [（54±2） °c,14 d],λ-cyhalothrin dissociation rate was less than 2%.[Conclusions] Each target of the sample meets the related requirement after test,and toxicity determination results showed that the sample was same with the traditional ME.The material cost is was only 40% of the same dosage EC,72% of tradition ME,77% of ME with Biological diesel fuel as solvent.
