摘要：
The subject of the invention is new cosmetic compositions, based on pigment nanoparticles and on fillers, which are completely transparent and free from whitening when they are applied on the skin, which possess sufficient UV screening properties for the addition of organic screening agents to be unnecessary, which are better dispersed than the compositions of the prior art and which are outstandingly stable. These compositions, when they are used in makeup, exhibit greater homogeneity of the colour and a colouring which is both transparent and more intense. The present invention also relates to methods of imparting these improved properties to makeup compositions.
