Abstract: The present invention relates to a composition for a keratin substance, such as skin, comprising: (a) at least one plate type filler having a particle size of 10 μm or less, preferably 5 μm or less, and more preferably 3 μm or less; (b) at least one pearlescent pigment having a particle size of 15 μm or less, preferably 12 μm or less, and more preferably 10 μm or less; and (c) at least one hollow or porous particle, wherein the (a) plate type filler has a refractive index of 2.0 or less, preferably 1.9 or less, and more preferably 1.8 or less, and the (b) pearlescent pigment has a colored reflection. The composition according to the present invention can provide a keratin substance with sufficient coverage of imperfections on the keratin substance, while providing the keratin substance with brightness and natural finish.

Abstract: The invention relates to a cosmetic composition, in particular in the form of a liquid cosmetic composition, comprising in a physiological medium (i) at least a plate type filler with refractive index>1.6 and having a particle size between 1 μm and 20 μm, preferably between 1 μm and 15 μm, (ii) at least a silicon elastomer, preferably a non-emulsifying silicon elastomer, and (iii) at least a filler having an oil absorption capacity greater than or equal to 1 ml/g. The composition is preferably used as a skin care or make-up base or primer intended to decrease the visibility of skin imperfections, in particular the pores and make the pore hiding effect long lasting.

Abstract: This invention relates to a cosmetic composition comprising, in a physiologically acceptable medium, at least one microcapsule comprising at least: —a core, —a first laminated coating surrounding said core comprising at least 45% by weight of the total weight, of a microcapsule of multilayer interference particles comprising at least one iron oxide, and —a second laminated coating surrounding said first coating, comprising between 10 and 40% by weight of titanium dioxide relative to the total weight of a microcapsule, said multilayer interference particles being released from said microcapsule(s) only when said composition is applied on a keratin material such as keratin fibers or the skin.

Abstract: The present invention relates to a composition in the form of an emulsion, comprising: (a) at least one oil-absorbable organic particle which has an oil-absorbing capacity of 170 ml/100 g or more, preferably 250 ml/100 g or more, and more preferably 400 ml/100 g or more, and a volume-average particle size of less than 30 μm, preferably less than 25 μm, and more preferably less than 20 μm, (b) at least one oil; (c) at least one emulsifier; (d) water; and (e) optionally at least one additional oil-absorbable particle, wherein the oil-absorbing capacity of the total of the (a) oil-absorbable organic particle and the (e) additional oil-absorbable particle in the composition is more than 170 ml/100. The composition according to the present invention can provide long-lasting matte effects, while imparting excellent texture.
