Pickering emulsions which are finely dispersed water-in-oil or oil-in-water systems comprising DOLLAR A (1) an oil phase which is at least 0.5% by weight based on the weight of the oil phase, at least one oil component selected from the group of oils with a viscosity lower than 30 mPaÈs (measured at a shear rate of 500 / s and a temperature of 25 ° C), DOLLAR A (2) contains a water phase, DOLLAR A (3) at least a type of microfine particles which have DOLLAR A a) an average particle size of less than 200 nm, DOLLAR A b) show both hydrophilic and lipophilic properties, which are therefore amphiphilic character and are dispersible both in water and in oil and the DOLLAR A c) are optionally coated on the surface, and DOLLAR A (4) at most 0.5 wt .-% of one or more emulsifiers. |
