Composition that has a covering power between 1 and 25 and intended to be applied to the skin, lips and / or the pimples, this composition comprising particles of at least one compound pigment, in a content in the composition between 0, 1% and 5% by weight, with respect to the total weight of the composition, these particles comprising: - an inorganic core comprising silica and having an average size between 10 nm and 50 nm, - at least a at least partial coating of at least one organic coloring matter, in an amount 10 sufficient so that the C * saturation of the composition is between 25 and 100, the mass proportion of organic coloring matter being between 10 parts and 500 parts by weight for 100 parts of the inorganic core, - the organic coloring matter being chosen from an organic azo dye pigment, an insoluble salt of sodium, potassium, calcium, barium, al Aluminum, zirconium, strontium, titanium, 15 acid dye chosen from an azo dye, where the covering power is measured as follows: the composition is 30 μm thick on an Erichsen contrast card , type 24/5, which has a black background and a white background, and trichromatic coordinates (X, Y, Z) are measured with the help of a CR-300 colorimeter; - Similar extensions are made on two other contrast cards and three measurements are made on each card, and then the average corresponding to these nine measurements is calculated, the coverage power is equal to 100 x Yn / Yb, where Yn is the average value of Y on a black background and Yb is the average value of Y on a white background. |
