Date Apr. 1, 1993.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. |
