Cosmetic and personal care formulations with goniochromatic non- quarter wave multi-quadrant multi-layer effect materials includes a transparent substrate such as borosilicate, a layer of high refractive index material on the substrate, and alternating layers of low refractive index and high refractive index materials on the first layer, the total number of layers being an odd number of at least three, all adjacent layers differing in refractive index by at least about 0.2 and at least one of the layers having an optical thickness which is different from all of the other layers. The resulting multilayer effect pigment is not a quarter-wave stack. Further color intensity, dimension and depth is obtained by combining the goniochromatic effect material with combination pigment which is obtained by combining a transparent substrate, an interference pigment and an absorption colorant. |
