摘要:
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.
摘要:
Pickering emulsions, which are finely disperse systems of the water-in-oil type, comprising (1) an oil phase, (2) a water phase, (3) at least one type of microfine particles which a) have an average particle size of less than 200 nm, which b) display both hydrophilic and lipophilic properties, i.e. which have amphiphilic character, and are dispersible both in water and in oil and which c) have optionally been coated on the surface, (4) at least one hydrocolloid and (5) at most 0.5% by weight of one or more emulsifiers.
摘要:
Use of one or more unsymmetrically substituted s-triazine derivatives in cosmetic or dermatological preparations for preventing the washing out or washing off, caused by the action of water, of endogenous skin cis- and trans-urocanic acid from human skin or the washing out or washing off, caused by the action of water, of cis- and trans-urocanic acid applied artificially to the skin from human skin.

摘要:
Cosmetic or dermatological stick preparations, which are finely disperse systems of the water-in-oil type, comprising a) an oil phase which comprises from 10 to 70% by weight, based on the weight of the fatty phase, of fatty and/or wax components which melt above a temperature of 40° C., b) a water phase, c) at least one modified phyllosilicate which exhibits both hydrophilic and also lipophilic properties, which thus has amphiphilic character and positions itself at the water/oil interface, and d) at most 0.5% by weight of one or more emulsifiers and method for their preparation.

摘要:
Emulsifier-free cosmetic or dermatological preparations, which are finely dispersed systems of the water-in-oil 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 substances.
