Definitions

  • Kit comprising alkoxysilane functionalized organic compounds X and Y
  • the present invention relates to a kit for coating keratin materials, in particular for non-therapeutic keratin material makeup or care, comprising at least two compositions and at least two alkoxysilane functionalized compounds X and Y that are capable of reacting together.
  • compositions according to the invention may be compositions for making up or caring for keratin materials, in particular the skin, the lips, the eyelashes, the eyebrows or the nails.
  • Each composition may be a loose or compacted powder, a foundation, a makeup rouge, an eyeshadow, a concealer product, a blusher, a lipstick, a lip balm, a lip gloss, a lip pencil, an eye pencil, a mascara, an eyeliner, a body makeup product or a skin colouring product.
  • the care composition may be a 'product for caring for the eyelashes or the lips, or a bodily and facial skincare product, especially an antisun product.
  • Lipstick and foundation compositions are commonly used • for giving an aesthetic colour to the lips or the skin, especially to the face.
  • These makeup products generally contain fatty phase ' s such as waxes and oils, pigments and/or fillers and optionally additives, for instance cosmetic or dermatological active agents.
  • these compositions When they are applied to the skin, these compositions have the drawback of transferring, i.e. of at least partly coming off, leaving marks, on certain supports with which they may come into contact and especially a glass, a cup, a cigarette, an item of clothing or the skin. This results in mediocre persistence of the applied film, making it necessary to regularly freshen the application of the foundation or lipstick composition. Moreover, the appearance of these unacceptable marks, especially on blouse collars, may put certain women off using this type of makeup.
  • Transfer-resistant lip and skin makeup compositions are thus sought, which have the advantage of forming a deposit that does not come off, at least partly, onto the supports with which they come into contact (glass, clothing, cigarette or fabrics) and that has good staying power.
  • mascaras that are anhydrous or that have a low content of water and/or water-soluble solvents, which are referred to as "waterproof mascaras", are known, which are formulated in the form of a dispersion of waxes in non-aqueous solvents and which show good resistance to water and/or to sebum.
  • the makeup film obtained after applying these compositions is not sufficiently resistant to water, for example during bathing or showering, to tears or to sweat, or even to sebum.
  • the mascara then has a tendency to crumble away over time: grains come off and unaesthetic marks appear around the eyes.
  • the aim of the present invention is to provide a novel route for formulating cosmetic compositions, especially makeup compositions, enabling the production of a film deposited on keratin materials, which has good transfer-resistance properties and/or good properties of staying power over time, in particular with respect to water and rubbing, and which leads a comfortable deposit on the skin, the lips, the eyelashes or the nails .
