The present invention relates to an agrochemical composition comprising a pesticide and a solvent of the formula (B) as described hereinbelow. The invention furthermore relates to a process for the preparation of the composition by bringing the pesticide and the solvent into contact; a use of the solvent of the formula (B) as a solvent for pesticides; methods for controlling phytopathogenic fungi and/or undesired vegetation and/or undesired insect or mite attack and/or for regulating the growth of plants, wherein the composition is allowed to act on the respective pests, their environment or on the plants to be protected from the respective pest, on the soil and/or on undesired plants and/or on the crop plants and/or on their environment; and on seed comprising the composition.

The present invention relates to the use of (oxidized) thioethers of polyalkylene oxides in washing and cleaning compositions, especially in dishwashing compositions, and to washing and cleaning compositions, especially dishwashing compositions, which comprise (oxidized) thioethers of alcohol alkoxylates. These (oxidized) thioethers are especially suitable as surfactants with rinse aid function (rinse aid surfactants). 'Oxidized' relates to the sulfur atom in the thioether, which may be present in oxidized form as sulfoxide (SO) or sulfonyl (SO). The invention also relates to particular oxidized thioethers of polyalkylene oxides.
