EC formulations are widely used because of their simple way of manufacturing.For application in the field,such formulations are diluted in water,forming an oil-in-water emulsion that allows a homogeneous distribution of active ingredients.Because EC formulations are solvent-based,the physical properties can vary widely depending on the solvent system used.The solvent type can affect the product quality such as viscosity,stability upon storage and upon dilution and potential for phy to toxicity.Traditionally,organic solvents such as xylene and solvent naphtha are used as solvent in EC.These compounds show a high capability of dissolving a wide range of active ingredients because of the presence of aromatic groups.Alternative solvents are mineral and vegetable oils and their derivatives,especially esterified fatty acids and methylated seed oils.The emulsifying system also influences the stability of the emulsion after addition of water and thus the performance of the pesticides on the targeted pests or weeds.Suitable emulsifiers are usually blended and not used as a single component.Such a blend can consist of two non-ionic surfactants.A mixture of a non-ionic and an anionic surfactant is used more frequently.The ratio of the two components is critical to find the most suitable HLB for the solvent.HLB or the hydrophilic-lipophilic balance system is well known to those who are skilled in the art.This scale is based on the relative percentage of lipophilic and hydrophilic surfactants.。
