Emulsifiable Concentrate

The formulation of an active ingredient as an Emulsifiable Concentrate (EC) is still common as it is simple to manufacture and low in cost. It contains an active ingredient, a solvent and an emulsifier system that allows the formulation to be mixed with water to form a stable emulsion. The Emulsol range of emulsifiers offered by Kaiser gives a uniform and stable emulsion that can be applied on crop. The commonly used emulsifier system is a blend of one anionic emulsifier component with one or more non- ionic emulsifier component. Some of the best known emulsifier system of Kaiser in the crop protection chemical industry are EmulsoI 371-A & Emulsol 371N, Emulsol 3522 & Emulsol 7066, etc with the advantage of:

  a) Rapid emulsifying action
  b) Broad spectrum activity
  c) Excellent spontaneity, blooming, thickness & stability
  d) Lower dosage levels
  e) Low viscosity free flowing liquids providing easy handling and pumping
  f)  Wide flexibility
  g) No phytotoxic effect
  h) No hydrolysis with toxicant

Emulsol emulsifiers are offered as modular system. The formulator is required to use generally two emulsifiers which form a matching pair.The ratio and overall dosage of emulsifiers for a given formulation is determined by simple laboratory technique as given in this presentation.
