abstract |
The present invention relates to improvements related to biocidal compositions. The present invention provides a solventless biocidal composition with improved efficacy comprising at least one water-insoluble biocide (preferably a herbicide) and a water-soluble carrier material, wherein The water insoluble biocide is dispersed in the carrier material in a nanodispersed form having a nanodispersed peak diameter of less than 1000 nm. The present invention also provides a method comprising spray drying of a biocide solution and an aqueous carrier solution to obtain an in-carrier solventless biocide dispersion that forms a nanodispersed biocide when dissolved in water. The present invention also provides an aqueous dispersion of a water-insoluble biocide and a water-soluble carrier, obtained by dispersion of a solvent-free composition in water.
