This invention refers to cosmetic compositions, particularly a skin treating preparation, comprising a transparent oil phase and a transparent aqueous phase, preferably with humectant effect, which permits a homogeneous mixture when being shaken, and which separates again in two transparent phases thereafter. These properties are achieved by the addition of 0.1 to 1.0% by weight of a C.sub.12 -C.sub.18 fatty acid triglycerol ester.
