Abstract: The present invention relates to hydrous, liquid, paste- or cream-like skin cleaning agents for the removal of strongly adhering soil, comprising anionic and/or amphoteric and/or non-ionogenic surfactants as washing-active substances, thickeners, at least one abrasive, and, optionally, adjuvants for the regulation of consistency, appearance, odor, and stability, such as pigments, fragrances, stabilizers, and preservatives, which skin cleaning agents are characterized by the fact that they comprise di-n-butyl adipate and/or di-isopropyl adipate as the exclusive solvents.
