Formulating a pesticide in microemulsion with three active componentsone- hydrophilic and two-lyophilic

Abstract

Microemulsion of a mixed pesticide with three active components of imidacloprid, fipronil and monosultap has been formulated and characterized. Pseudoternary phase diagrams and cloud points of microemulsions are drawn and measured with changing mass ratios of surfactant to co-surfactant (Km). It was found out that the mixed pesticide microemulsion can be formulated at the Km of 1:1 and the manufacturing temperature of 25-55℃. Properties such as density, surface tension, and contact angle of as-prepared microemulsion are characterized.
