The invention relates to a dispersion of melanic pigments containing in a medium selected amongst: a) the straight or branched monoalcohols comprising at least 3 carbon atoms; the straight or branched polyols comprising at least 2 carbon atoms; the saturated or unsaturated cycloaliphatic alcohols comprising at least 6 carbon atoms; the aromatic alcohols comprising at least 6 carbon atoms; the C8?-C22? fatty acid esters and C1?-C6? alcohol esters or the C2?-C6? polyol esters; the C1?-C6? aliphatic acid esters or the C8?-C22? aromatic acid and fatty alcohol esters; the C8?-C22? fatty acid esters and the c8?-C22? fatty alcohol esters, the C6?-C22? polyacid and alcohol esters, the hydroxylated fatty acid diesters; the straight or branched paraffins comprising at least 8 carbon atoms; the silicone oils; and the mixture of these different organic compounds, or b) an emulsion comprised of a liquid defined under a), non water miscible, water and an emulsifying agent, a melanic pigment in the form of particles in which at least 75 % of the particles have a grain size smaller than 10 microns. The invention also relates to a method for the preparation and the utilization of such dispersion in cosmetics. |
