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.

Low-viscosity cosmetic or dermatological oil-in-water preparations, 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 DMA 45 computerized digital density meter from chempro/PA at 25° C.) is not greater than 0.01 g·cm−3.
Method of stabilizing O/W formulations, characterized in that the density of the oil phase is matched to the density of the water phase by adding hydrophobic and/or amphiphilic solids in such a way that the difference in density between the two phases (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.
