Oil-in-water emulsions

The invention relates to aqueous formulations containing 1 to 70% by weight of an agrochemical active substance which is sparingly soluble in water, besides an amount which inhibits crystallization of the active substance or breaking of the emulsion, of a compound of the formula I

Aqueous formulations and their use

Oil-in-water emulsions (microemulsions) containing 0.01-80% by weight of at least one agrochemical active substance of low water-solubility, one active substance for combating pests in the domestic and hygiene sector and/or one pharmacologically active substance, 1% to 30% by weight of an emulsifier mixture of non, ionic and anionic compounds and at least one alkylarylsulfonic acid salt, as defined in the description, as well as water and, if appropriate, 1% to 30% by weight of at least one solvent of low water-miscibility and/or one solubilizer, and if appropriate 0.05% to 15% by weight of additives, the sum of the components in each case being 100% by weight, a process for the preparation of these aqueous microemulsions and their use.
