COSMETIC COMPOSTIONS HAVING INCREASED COLOR INTENSITY AND METHOD FOR PRODUCING SAME

摘要

Color intensity of a pigment-containing cosmetic composition is increased by incorporating in the composition a color intensifying amount of: (i) a C<SUB>12</SUB>-C<SUB>24</SUB> fatty alcohol, preferably a C<SUB>14</SUB>-C<SUB>20</SUB> fatty alcohol, the fatty alcohol preferably being a branched chain fatty alcohol having a C<SUB>6</SUB>-C<SUB>10</SUB> alkyl branch and (ii) an unsaturated dimerized or trimerized C<SUB>14</SUB>-C<SUB>24</SUB> fatty acid, preferably an unsaturated dimerized or trimerized C<SUB>16</SUB>-C<SUB>20</SUB> fatty acid that has 2 to 4, preferably 2, unsaturated bonds. Diisostearyl dilinoleate is preferred. Triisostearyl trilinoleate is most preferred. When then composition is an oil-in-water emulsion, the triisostearyl trilinoleate or diisostearyl dilinoleate is added to the emulsion after it is prepared in order to maximize color intensification.
