摘  要:
[Aims] The aim was to explore the application of polymeric emulsifier in oil-in-water emulsion. [Methods] An environmental friendly and novel formulation of beta-cyfluthrin EW was prepared with polymeric emulsifier by the phase transfer method, in addition, the physical and chemical performance indexes of the formulation were tested.[Results] The optimum formula of be ta-cyfluthrin 5% EW was cyclohexanone 8%, polymeric emulsifier 4%, in which the ratio of N-200 to G-200 was 2:2, and tap water up to 100%. The formula was stable in room temperature, low temperature and thermal storage, and the physical and chemical performance indexes met the technical standard for oil-in-water emulsion. [Conclusions] The particle size of oil droplet was measured by laser particle analyzer, and the results showed that the physical stability of emulsion and particle size distribution were closely related.
