Claims43
A cosmetic composition comprising, in a physiologically acceptable medium, particles of at least one composite pigment comprising at least one binder and an inorganic core at least partially coated with at least one organic coloring substance, wherein the inorganic core comprises TiO2, wherein the mean size of the inorganic core ranges from 1 nm to 100 nm, wherein the at least one organic coloring substance is present in an amount ranging from 10 to 500 parts by weight per 100 parts of the inorganic core, and wherein the color variation ΔE between the color of the bulk composition and the color after application is less than 20.
A method for making up skin, lips, and integuments, comprising applying to the skin, lips, and integuments a composition comprising, in a physiologically acceptable medium, at least one oil in an amount ranging from 0.1% to 90% by weight relative to the total weight of the composition and particles of at least one composite pigment comprising at least one binder and an inorganic core at least partially coated with at least one organic coloring substance, wherein the inorganic core comprises TiO2, wherein the mean size of the inorganic core ranges from 1 nm to 100 nm, and further wherein the color variation ΔE between the color of the bulk composition and the color after application is less than 20.
