New Formulation Types in Plant Protection: Emulsion, Oil in Water (EW)

Abstract

Characteristics of emulsion, oil in water (EW) as a pesticide formulation system are surveyed. A short description is given of its formation and effect of surface active ingredients on the stability of such systems. Typical instances of instability occurring during formation are discussed, as well as possibilities for securing kinetic stability. Furthermore, possible procedures for preparation and industrial production of emulsions are offered. Finally, some basic test methods are proposed, and advantages listed of that formulation type overemulsifiable concentrates.
