Emulsifier-free finely disperse systems of the oil-in-water and water-in-oil type
Abstract:
Pickering emulsions, which are finely disperse systems of the water-in-oil or oil-in-water 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 cyclodextrin and (5) at most 0.5% by weight of one or more emulsifiers.
