Description

The subject of the present invention is an eyelash coating composition

  or mascara, in particular make-up or non-therapeutic care of the eyelashes, comprising at least two compounds X and Y, able to react together, at least one of the compounds being silicone, and fibers. The invention also relates to a cosmetic kit comprising said compounds X and Y. The composition may be an eyelash makeup composition, an eyelash makeup base, a composition to be applied to a mascara, also called a top-coat, or still a composition for cosmetic treatment of the eyelashes. Mascara is especially intended for human eyelashes, but also false eyelashes.

  In the case of coating compositions for eyelashes or mascaras, it is known in particular anhydrous mascaras or low water content and / or water-soluble solvents, so-called waterproof mascaras, formulated in the dispersion state of waxes in non-aqueous solvents and which have good resistance to water and / or sebum.

  However, the makeup film obtained after the application of these compositions is not sufficiently resistant to water, for bathing or showers for example, with tears or sweat or sebum. The mascara then tends to crumble in time: grains are deposited and unsightly marks appear around the eyes. In addition the use of fibers to achieve an effect of elongation of the eyelashes does not promote a uniform and smooth deposit on the eyelashes, resulting in poor strength of the fibers that tend to unhook more easily. This results not only in a deterioration of the deposit and therefore the overall makeup result but also in a discomfort for the user.

  The invention makes it possible to propose an alternative formulation route for an eyelash coating composition which makes it possible to obtain, on the eyelashes, a makeup with a very good hold, which leads to an elongated result and a continuous film. smooth, intense black and shiny. The compositions lead to eyelash makeup having good performance of both the fibers and the overall makeup film. In addition, the compositions according to the invention allow a smooth and homogeneous application and the mascaras according to the invention allow a makeup result that holds more than 1 day, better more than 3 days and better still beyond a week.

  The inventors have discovered that it is possible to obtain such properties by using compositions comprising fibers and preferably silicone compounds which polymerise and / or crosslink in situ so
