It is well known that emulsifiable concentrates (EC), besides good properties have problemwith a high solvent content thus are not environmental friendly and can cause problemsfor users. The interest in developing oil-in-water emulsions (EW) instead emulsifiableconcentrates is increasing due to toxicological problems with solvents. Oil-in-water emulsionscan reduce phytotoxicity, ecotoxicity and dermal toxicity, have a higher flash pointthan EC and are safer in transport and storage; also EW are more compatible with waterbased SC formulations for blends of active ingredients. Plant protection often includes theuse of some pyretroides as active ingredients, for example Cypermethrin, alone or combinedwith Chlorpyrifos. It is a very old product which is formulated as EC formulation. Inthis study oil-in-water emulsion (EW) was developed with the same active ingredients. TheEW formulation was tested and the results show that it was stable and therefore could beused in plant protection.
