Emulsifiable Concentrates



Liquid, homogenous preparation to be applied as an emulsion after dilution in water

ECs are still one of the most common formulation types for pesticide products worldwide.
EC formulations contain stable active ingredients, solubilized in organic solvents, added of emulsifiers.
The spontaneous emulsion can be achieved by selecting one or more surfactants based upon their ability to emulsify the solvent system, including the active ingredient, into water.
Physically stable emulsion is formed by balancing the water soluble and oil soluble surfactant components at the water/solvent interface.
Such EC formulations are diluted in water, forming oil-in-water heterogeneous spontaneous emulsion, with emulsion droplets in the size range of 0.1 to 1.0μm.
When applied, EC formulation allow homogeneous distribution of active ingredients, which is essential for its effectiveness.
Pros:
  • Simple manufacturing
  • Good chemical stability
  • Better biological activity
  • Cons:
  • High solvents quantity
  • Often low flash point
  • Plastics and rubbers affected
  • Disadvantages can be partially overcome by choosing higher flash point solvents or using new packaging technology such as coextruded containers or water-soluble sachets.
