  • Patent number: 6372202
    Abstract: The present invention relates to cosmetic compositions, in particular make-up compositions, comprising an orange pigment with an intense and saturated color which does not generate free radicals. This pigment is a diketodiarylpyrrolopyrrole derivative of formula: in which A and B are identical or different aryl radicals and DPP is a 1,4-diketo-3,6-diarylpyrrolo[3,4-c]pyrrolidyl radical, the diaryldiketopyrrolopyrrole derivative of formula (I) being substituted by 0 to 6 mol of —SO3M per mole, M being hydrogen or a metal or ammonium cation.

  • Patent number: 6333053
    Abstract: Use of a specific particulate phase in a cosmetic composition, in particular a make-up composition, and cosmetic composition comprising such a particulate phase. Use of a particulate phase comprising particles with mean dimensions ranging from 5 to 100 microns and preferably from 20 to 50 microns and comprising at least two consecutive faces, the normals of which at the median point form, between one another, an angle at least equal to 90°, in a cosmetic composition, in particular a make-up composition, for the purpose of limiting, decreasing or eliminating the blemishes of keratinous substances and/or of modifying the perception of the volume of some regions of the said substances. Cosmetic composition, in particular in make-up composition, such as a foundation, comprising such a particulate phase.

  • Patent number: 6042842
    Abstract: The present invention relates to cosmetic compositions, in particular make-up cosmetic compositions, comprising a novel red pigment with an intense and saturated color which does not generate free radicals. This novel pigment is a diketopyrrolopyrrole (DPP) of formula: ##STR1## in which R.sub.1 and R.sub.2 independently represent a hydrogen atom, a C.sub.1 to C.sub.18 alkyl radical, a C.sub.3 to C.sub.12 alkenyl radical, a C.sub.2 to C.sub.5 alkoxycarbonyl radical or a phenyl radical which is optionally substituted by a halogen and R.sub.3 and R.sub.4 independently represent a hydrogen atom, a C.sub.1 to C.sub.18 alkyl radical, a C.sub.1 to C.sub.4 alkoxy radical, a halo radical or a phenyl radical, or a --SO.sub.3 M group with M being a hydrogen atom, a metal atom or an ammonium group, it being possible for the alkyl, alkenyl and alkoxy radicals to be linear or branched.
