Abstract

A sulfentrazone composition in the form of a microemulsion includes 5-15% weight by volume of sulfentrazone, an aprotic dipolar organic solvent including 46-50% w/v, a polar solvent including from 0-4% w/v, wetting agents 20% or 41% w/v, a coadjuvant from 0-5% w/v, and a nonionic surfactant from 0-3.5% w/v, adjuvant from 0-17.5% w/v and dispersing agents from 0-2% w/v. The composition showed a reduction in the application dose compared to other concentrated compositions of the same active ingredient, and by virtue of the combination of its other formulation components that the investigators used for its realization, formulation offered protection against physicochemical losses (evaporation, rolling, etc.), absorption rate improvement, significant reduction of environmental impact variables, drastic reduction of solvent evaporation, allowing keeping the active ingredients in liquid phase, allowing hydrophobic active ingredients to be solubilized in water, a large increase in the Surface/Volume ratio and controlled release of active ingredients.
