THICKENING COMPOSITION FOR USE IN AGROCHEMICAL FORMULATIONS, USE OF A THICKENING COMPOSITION AND AGROCHEMICAL FORMULATIONS CONTAINING A THICKENING COMPOSITION

摘要

The present invention describes a novel thickening composition that comprises a mixture of esters of an alkoxylated polyol and is used to enhance the viscosity of agrochemical formulations. The composition according to the present invention may present itself in solid for or in liquid form, in this latter case further comprising one or more surfactants, solvents, and optionally water. The thickening composition described in this invention is compatible with a large variety of pesticides and inert components used in agrochemical formulations, and it has evidence that it is capable of improving the stability and the effectiveness of the said formulations.

主权项

1. A thickening composition for use in an agrochemical formulation, the thickening composition comprising a mixture of:
a. 35 to 60% by weight of a mixture of di-, tri-, tetra-, penta- and hexaesters of stearic acid with an ethoxylated sorbitol containing more than 400 moles of ethylene oxide (EO) for each mole of sorbitol, wherein the tetra- and pentaesters contain at least 30% by weight of the total esters; b. 25% to 40% by weight of surfactants selected from the group consisting of polyethylene glycol esters, ethoxylated sorbitan esters, and mixtures thereof; c. 0.5 to 2.0% by weight of glycol solvents; and d. optionally, water up to 27% by weight.
