Abstract: The present invention relates to a composite particle comprising: at least one hydrophilic core particle; and a plurality of hydrophobic particles, wherein the surface of the hydrophilic core particle is substantially discontinuously covered by the hydrophobic particles. The novel composite particle according to the present invention can have surface active properties sufficient to prepare stable Pickering emulsions, and can maintain the surface active properties over a long period of time. The present invention also relates to a method for preparing the above composite particle.

Abstract: The present invention concerns composite particles comprising: i) a matrix containing at least one inorganic and/or at least one organic material and ii) at least one inorganic UV filter which is doped by at least one transition metal. The present invention also concerns a composition containing, in a physiologically acceptable medium, at least the composite particles as defined above.The invention also concerns a cosmetic method for caring for and/or making up a keratinous substance, which consists in applying, to the surface of said keratinous substance, at least one composition as defined above and more particularly a cosmetic method for: a) limiting the darkening of the skin and improving the colour and uniformity of the complexion, and b) treating aging of keratinous substances.
