Oil in Water Emulsion - EW

Due to the low flash point of organic solvents efforts are being made to replace them with universal solvent - Water. Many such environment friendly agro chemical formulations have been commercialized. Emulsol B -25 (for Butachlor), Emulsol TEW (for Triacontanol), Emulsol NB (for Nitrobenzene) are the few examples which have been developed with out incorporating any solvent after extensive R&D.

For preparing an EW formulation the toxicant is blended with Emulsifier and water is slowly added under high shear mixing. A guided receipe is as given below:  

Butachlor 48 EW            Nitrobenzene 20 w/v
Butachlor a.i.           48            Nitrobenzene   22
Emulsol B25           5            Emulsol TEW          2
Water           q.s.to make 100            Water   q.s.to make 100
