EW Surfactants

They can be viewed as a safer and ecologically friendlier option when compared to emulsifiable concentrates (EC). In an emulsion concentrate (EW), the primary phase is water, in contrast to ECs that use organic solvents. This choice comes with several advantages, including reducedphytotoxicity, no flammability concern, easier handling, and a smaller ecological footprint. The stability of EW formulations is maintained through the inclusion of particular polymeric surfactants at suitable concentrations.

The emulsion is already well-established in the formulation and is merely further diluted in the spray mixture.

• • Easy production
• • High biological activity
• • Strong chemical stability
• • Automatic emulsification upon dilution

• • Requires costly solvents
• • Solvents may harm spray applicator plastics and rubbers
• • Active ingredients must fully dissolve in the solvent across temperature ranges
• • Water-miscible solvents can lead to active ingredient crystallization issues upon dilution
