Cosmetic composition comprising porous particles incorporating optically active substances
An object of the invention is to offer an optical additive capable of adequately activating the effects of incorporated optically active substances, providing the base with such optical effects, having a suitable sensation and level of safety, and having exceptional cosmetic properties. A cosmetic composition comprising in a physiologically acceptable medium (a) silicium-based porous particles having an aspect ratio of at least 2 and (b) an optically active substance incorporated into said porous particles is offered. The incorporated optically active substances are selected from among UV screening substances, fluorescent substances and photochromic substances.
The present invention relates a cosmetic composition consisting of at least one pigment comprising an elongated core, a red organic colorant coating at least partially the core, and at least one binder between the core and the organic colorant.

Composition comprising particles of at least one polymer dispersed in at least one fatty phase and at least one apolar oil
The present disclosure relates to a cosmetic composition comprising particles of at least one polymer dispersed in a fatty phase, the at least one fatty phase is free of volatile oil or comprises less than 50% by weight of volatile oil relative to the weight of the at least one fatty phase, and the liquid fatty phase comprising at least 5% by weight of at least one sparingly polar or apolar oil. The apolar or sparingly polar oil may be, for example, a non-volatile hydrocarbon-based apolar oil.
