Abstract: The invention relates to the use of a plant extract of a plant of the Limnophila genus, in particular an extract of the plant species Limnophila conferta, as a cosmetic agent or as an active agent in cosmetic compositions.

Abstract: The invention relates to cosmetic compositions comprising a black colour subtractive mixture consisting of one blue pigment (ferric ammonium ferrocyanide and/or ultramarine blue), at least one yellow organic pigment and at least one red organic pigment, which are mixed homogeneously, said mixture having a very dark black color.

Abstract: The invention relates to cosmetic compositions comprising a black colour subtractive mixture consisting of at least one blue organic pigment, at least one yellow organic pigment and at least one red organic pigment, which are mixed homogeneously, said mixture having a luminance value L*(15°) of less than 30.

Abstract: The invention relates to novel microgel-containing essentially organic solvent nail varnishes. The microgels are particularly acrylic microgels. The invention also relates to the use of these microgels for modifying the physical properties of an essentially organic solvent nail varnish composition, and/or the properties of the film obtained during the application of said composition.

Abstract: The invention relates to a dyestuff of plant origin, obtained from a colored part of a plant species, the cell tissues of which contain iridisomes responsible for the coloration of said part. It relates most particularly to a blue dyestuff obtained from the arils of the seeds of the plant species Ravenala madagascariensis. It also relates to compositions, in particular cosmetic compositions, especially intended for making up the skin or superficial body growths, containing said dyestuff.

Abstract: The invention relates to a cosmetic composition for making up the skin, lips or superficial body growths, comprising a cosmetic base, at least one coloured inorganic pigment [A] in an amount sufficient to define a first colour of said composition in its body, and at least one pigment [B] chosen from organic dye lakes, the colour of which is different from that of the pigment [A], in an amount sufficient to define a second colour, radically different from said first colour, which is revealed after the application of said composition on the lips, skin or superficial body growths.

Abstract: The invention relates to a solid coloring material obtained by precipitation, in an aqueous medium, of the reaction product of an alkali metal silicate with a colored complex obtained by reaction, in aqueous solution, of a hydrolysable tannin or of a plant extract comprising it with a salt of a metal cation. The invention also relates to a cosmetic composition intended for making up the skin or superficial body growths comprising this coloring material. It also relates to a method for making up the skin or superficial body growths comprising the topical application of this cosmetic composition.

Abstract: The present invention relates to a cosmetic composition, which comprises a combination of at least two osmolytes chosen from the group comprising taurine or a derivative thereof, inositol, betaine and trehalose. This composition is intended for restoring, maintaining or reinforcing the moisturization of the skin and/or for protecting it against different types of stress and/or for preventing or retarding the appearance of the signs of aging of the skin, or for attenuating the effects thereof, or alternatively for promoting cell or tissue longevity.

The invention also relates to a cosmetic composition intended for making up the skin or superficial body growths comprising this coloring material. It also relates to a method for making up the skin or superficial body growths comprising the topical application of this cosmetic composition.

Abstract: The invention relates to a process for the preparation of a stable microdispersion of particles comprised of acrylic polymers in an organic solvent used as reaction medium in the presence of a stabilizing agent comprised of a block copolymer, characterized in that said acrylic polymer is obtained by radical polymerization of at least one acrylic monomer in the presence of a block copolymer based on polymethyl methacrylate (PMMA) and polytert-butyl acrylate (PtBuA). It also relates to microdispersions which may be obtained by said process as well as to microgels produced from said microdispersions and compositions, particularly cosmetic compositions such as nail varnish.

Abstract: The invention relates to a chain end functionalised polymer of formula: ##STR1## in which: the polymer chain (P) is a hydrophobic chain obtained by radical polymerisation of at least one monomer,R represents a hydrogen atom or a linear or branched hydrocarbon chain having 1 to 8 carbon atoms optionally substituted with at least one group selected from CO.sub.2, NH.sub.2, OH or a phenyl group, itself being optionally substituted,A and B, identical or different, each represent a single bond, a saturated or unsaturated linear or branched hydrocarbon chain having from 1 to 16 carbon atoms, it being possible for it to contain an amide bond or a peptide chain having 2 to 4 amino acids, particularly natural amino acids,the NH.sub.2 and/or COOH groups being free or salified.The invention also relates to the use of the above products as surfactants and more particularly as wetting agents, dispersing agents of solid particles and for preparing microdispersions of polymers, in particular microgels and microlatexes.
