In this paper, first, by adding Iron (III) chloride hexahydrate (FeCl 3 (H 2 O) 6 ), Nickel(II) chloride hexahydrate (NiCl 2 (H 2 O) 6 ), Cobalt (II) chloride hexahydrate (CoCl 2 (H 2 O) 6 ), surfactants of magnetic cetyltrimethylammonium bromide and dodecyltrimethylammonium bromide were prepared. Then, for the first time, with the help of these salts, the natural surfactant extracted from the Licorice roots has been magnetized as an environmentally friendly surfactant. Next, the surface properties of these materials were examined and the performances of magnetic and non-magnetic samples were compared. Ultimately, a mixture of synthetic and natural magnetic surfactants was used to disperse the oil, and the emulsion produced was collected by the magnet, and its performance was compared with the mixture of natural and synthetic non-magnetic surfactants.
