Emulsifier-free finely dispersed systems of the oil-in-water or water-in-oil type

Pickering emulsions, which are finely disperse systems of the water-in-oil or oil-in-water containing DOLLAR A (1) an oil phase, DOLLAR A (2) a water phase DOLLAR A (3) at least one type of microfine particles, the DOLLAR a a) have an average particle size of less than 200 nm, the show DOLLAR a b) both hydrophilic and lipophilic properties, ie which have amphiphilic character, and both in water and in oil dispersible and DOLLAR a c) optionally are coated on the surface, DOLLAR a (4) at least one electrolyte and DOLLAR a (5) at most 0.5 wt .-% of one or more emulsifiers.
