Goniochromatic/light reflecting cosmetic compositions well suited for making up the skin, lips, hair or integuments, contain (a) at least one goniochromatic coloring agent suited for creating a goniochromatic colored background and (b) an amount of light reflective particles suited for creating highlight points that are visible to the naked eye, formulated into (c) a topically applicable, physiologically acceptable medium therefor.

Goniochromatic/light reflective cosmetic makeup compositions

Goniochromatic/light reflecting cosmetic compositions well suited for making up the skin, lips, hair or integuments, contain (a) at least one goniochromatic coloring agent and (b) an amount of light reflective particles different from said at least one goniochromatic coloring agent and selected from the group consisting of (i) particles of a natural or synthetic substrate at least partially coated with at least one layer of at least one metal, (ii) particles of a synthetic substrate at least partially coated with at least one layer of at least one metallic compound, (iii) particles which comprise a stack of at least two layers of materials having different refractive indices, at least one of such layers optionally comprising a polymer, and (iv) metal oxide particles, formulated into (c) a topically applicable, physiologically acceptable medium therefor.

Liquid cosmetic composition in the form of an emulsion comprising at least two distinct phases and containing at least one photochromic coloring agent and at least one non-photochromic coloring matter, characterized in that the photochromic coloring agent(s) and the non-photochromic coloring matter(s) are located in separate phases of the emulsion. Application to the make-up and/or the care of the skin and/or its appendages.

Cosmetic composition containing a photochromic colouring agent and its use for skin and/or skin appendage make-up and/or care

The invention relates to a transparent or translucent colored cosmetic composition for making up the skin, lips and superficial body growths comprising a transparent or translucent cosmetic base and at least one coloring agent in an amount such that the transmission of a 10 &#x3bc;m layer of the final composition, measured at the wavelength of the maximum of one of the absorption peaks of the coloring agent, is between 20% and 80%.

Colored transparent or translucent cosmetic composition

The invention relates to a process for the manufacture of a colored make-up cosmetic composition which makes it possible to produce a transparent or translucent colored coat on the skin, lips or superficial body growths, comprising the following successive steps:

Process for making a colored make-up cosmetic composition with controlled transmittance

The present invention relates to a new makeup kit comprising a first, goniochromatic pigment composition which is intended to form a base layer and a second, conventional pigment composition having one of the colors of the first pigment, the second composition being intended to form a surface layer comprising decorative motifs. Depending on the viewing angle, therefore, it is possible to see the said motifs appear or disappear. This kit is intended in particular for making up the nails, lips, cheeks or eyelids, or else the body. The invention also relates to a method of making up the human face, lips or body.

Method and makeup kit containing goniochromatic and monochromatic pigments

The present invention relates to a stable water-in-oil emulsion for cosmetic, pharmaceutical or hygiene use, comprising an aqueous phase and a fatty phase comprising a silicone oil, characterized in that it comprises at least one &agr;,&ohgr;-substituted oxyalkylenated silicone, the emulsion having a viscosity ranging from 100 cps to 200 poises, at 25&deg; C. and at a shear rate of 200 s . The invention also relates to the compositions comprising such an emulsion, and to its applications in the cosmetics field.

W/O emulsion composition comprising such an mulsion and cosmetic pharmaceutical or hygiene use thereof

Water-in-oil emulsion, composition comprising such an emulsion, and use thereof

Cosmetic composition, in particular a make-up composition, comprising a pigment derived from pyrrolopyrrole

Use of a specific particulate phase in a cosmetic composition, in particular a makeup composition, and cosmetic composition comprising such a particulate phase

A cosmetic make-up product, comprising first and second components, separately packaged, each containing a cosmetically acceptable medium, the first component containing at least one photochromic coloring agent which is capable of producing at least one color in the presence of ultraviolet light, and the second component containing at least one agent which screens ultraviolet light.

Make-up product combining a photochromic pigment and a UV screening

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. By virtue of this pigment, it is possible to protect the skin, lips and keratinous fibers from free radicals without using antioxidizing agents in the composition.
