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 over emulsifiable concentrates.

U radu je dat pregled karakteristika emulzija ulja u vodi kao sistema za formulisanje pesticida. Dat je kratak pregled njihovog obrazovanja i uticaja površinski aktivnih materija na stabilnost ovih sistema. Diskutovane su tipične nestabilnosti do kojih dolazi pri njihovom obrazovanju kao i mogućnosti za postizanje kinetičke stabilnosti. Dalje, ukazano je na načine pripremanja i industrijske proizvodnje emulzija ulja u vodi. Na kraju, istaknute su osnovne metode za njihovu proveru, a ukazano je i na prednosti koje ovaj tip formulacija ima u odnosu na koncentrate za emulzije.
