Emulsifier-free finely disperse systems of the oil-in-water and water-in-oil type

   
   

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.

Las emulsiones de Pickering, que son finalmente sistemas de la dispersión del agua-en-aceite o del tipo aceite/agua, abarcando (1) a la fase del aceite, (2) una fase del agua, (3) por lo menos un tipo de partículas que a) tenga un tamaño de partícula medio de menos de 200 nm, que b) las características hidrofílicas y lipofílicas de la exhibición, es decir que tienen carácter amphiphilic, y son dispersibles en agua y en aceite y que del microfine ha estado cubierto c) opcionalmente en la superficie, (4) por lo menos un cyclodextrin y (5) en la mayoría 0.5% en peso de unos o más emulsores.
