The effect of hydrocarbon chain of co-surfactant,chlorpyrifos solution content,chlorpyrifos content in oil,temperature,and water hardness were investigated by surfactant/cosurfactent/oil/water pseudo-ternary phase diagram to evaluate the factor effect in forming chlorpyrifos microemulsion.

为考察各因素对毒死蜱微乳液形成规律的影响，系统研究了助表面活性剂直链醇碳链长度、毒死蜱溶液含量、油相中毒死蜱的含量、温度及水质对表面活性剂/直链醇/毒死蜱溶液/水体系拟三元相图的影响规律。

For the mieroemulsions, Miglyol 812 was chosen as oil phase, SbPC and HS-15~ as surfactants, PEG400 and ethanol (7:3) as cosurfactant and the double-distilled water as water phase. Pseudo-ternary phase diagrams were constructed to obtain the concentration range of each component for the microemulsion formation. The effects of various ratio of SbPC to HS-15 and different weight ratios of surfactant to cosurfactant on the droplet size were investigated, as well as viscosity and stability of microemulsion. The constitute of stable blank ME with more oil and little surfactant was confirmed.
