Abstract: 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.
