The present invention relates to the technical field of delivery systems for agrochemical active ingredients or pharmaceutical active ingredients. The present invention primarily relates to certain compositions in solid form comprising as constituent (a) at least one agrochemical or pharmaceutical active ingredients, as constituent (b) urea, and as constituent (c) at least one non-ionic surfactant. The present invention also relates to products obtainable or obtained by the processes defined in the context of the present invention. The present invention further relates to formulations comprising these compositions or products and application mixtures obtainable or obtained by dilution of these compositions or products with water or aqueous surfactant solutions. The present invention further relates to processes for preparing these compositions, products, formulations and application mixtures as well as to uses thereof and methods of using these compositions, products, formulations and application mixtures.

A composition comprising a first insect repellent compound, a second insect repellent compound, and a polymer that is miscible in the first insect repellent compound at 23 C. The polymer is dissolved in the first insect repellent compound. An example first insect repellent compound is N,N-diethyl-meta-toluamide, and example second insect repellent compounds are nootkatone, permethrin, or transfluthrin.
