  • the present invention also relates to a makeup and/or care process, preferably for the lips, which consists in applying said composition, and also to a device suitable for the composition.
  • compositions for making up and/or caring for the lips in particular fluid compositions such as liquid lipsticks, which are stable and endowed with satisfactory properties in terms of application (glidance on application, ease of spreading and fineness of the deposit), but also in terms of the makeup effect of the deposit on the lips, for instance the absence of migration of the deposit, preferably without becoming tacky, is an ongoing objective.
  • lip glosses are anhydrous formulations whose relatively viscous texture is usually applied by means of a brush dipping into the composition.
  • the deposit is relatively thick, which gives it a more or less tacky nature, especially induced by the use of ingredients, in particular nonvolatile oils or polymers that provide gloss.
  • This tacky nature may be reflected by adhesion of the made-up lips to each other, resulting in a sensation of discomfort to the user.
  • the coverage of the deposit is variable and it has rather limited persistence.
  • compositions As examples of such compositions, mention may be made especially of those described in patent applications WO 2014/154700 and WO 2014/154701 , which are thus in emulsion form, comprising water, non-volatile and volatile oils and an acrylic film-forming polymer bearing silicone dendrimer-based units. These compositions make it possible to obtain an extremely thin deposit, which is virtually imperceptible on the lips, highly coloured and covering, non-tacky, non-migrating and with a matte result due to the large amounts of volatile species initially present in the composition.

  • the deposited film has the advantage of always being very thin, homogeneous, allowing a precise contour to be defined on the lips.
  • the deposit obtained is comfortable, not only in the sense that it is flexible on the lips and does not cause any sensation of dryness thereon, but also because it remains mobile and modulable once applied, without degradation of the other performance qualities, especially the absence of migration and the persistence.
  • the cosmetic composition for making up and/or caring for the lips according to the invention is in the form of an emulsion, especially a water-in-oil (inverse) or oil-in-water (direct) emulsion, preferably in the form of an (inverse) water-in-oil emulsion.
