Pickering emulsions, which are finely disperse systems of the water-in-oil or oil-in-water type, comprising (1) an oil phase which comprises at least 0.5% by weight, based on the weight of the oil phase, of at least one oil component chosen from the group of oils having a viscosity which is less than 30 mPa.s (measured at a shear gradient of 500/s and a temperature of 25° C.), (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, and (4) at most 0.5% by weight of one or more emulsifiers. |
