Abstract: Emulsifier-free cosmetic or dermatological preparations, which are finely dispersed systems of the oil-in-water type, comprising 1. an oil phase, 2. an aqueous phase and 3. one or more types of micronized, inorganic pigments which a) have an average particle size of less than 200 nm, and whose particles b) have both hydrophilic and lipophilic properties, i.e. have an amphiphilic character, and thus position themselves at the water/oil interface, and which c) are selected from the group consisting of metal oxides, which d) are optionally coated on the surface and also optionally comprising further cosmetic or pharmaceutical auxiliaries, additives and/or active ingredients.

Abstract: Low-viscosity cosmetic or dermatological preparations of the oil-in-water type, which comprise an oil phase, in which hydrophobic and/or amphiphilic solids are incorporated, and a water phase, where the difference in density between the oil phase and the water phase (determinable using a computerized digital density meter of the type DMA 45 from chempro/PA at 25° C.) is not greater than 0.01 g·cm−3, and method of stabilizing O/W formulations.
