LIPOSOME COMPOSITIONS AS AQUEOUS DISPERSIONS BASED ON MODIFIED NANOPIGMENTS AND PROCESS FOR PREPARING THE SAME

The invention relates to a liposome composition as aqueous dispersion to be used in textile and leather industry and to a process for preparing the same. According to the invention, the composition consists of 5...8% blue, red or black nanopigments modified/functionalized with sulphonic and/or carboxylic or phenyl-sulphonic functional groups, 2.5...10% encapsulation agent, such as soy lecithin, related to 100% pigment, 4...10% thickener, such as carboxymethylcellulose and 50...92% distilled water, the parts being expressed by mass. The process, as claimed by the invention, consists in microdispersing the pigments, at speeds of 6000...12000 rpm, for 30...90 min, on cooling bath, at 20°C, nanodispersing them by ultrasonication, at a power of 750 W, for 30...60 min, in cooling bath, followed by stabilization by stirring for 30 min, at a speed of 300 rpm.
