Definitions

  • the present invention relates to a process for making up the skin and/or the lips, in several steps, in which a coating agent formed in situ or beforehand is used, by interaction by hydrogen bonding of at least one polyphenol X comprising at least two different phenol groups with at least one particular polyoxyalkylenated compound Y that is capable of forming at least two hydrogen bonds with said phenol groups of the polyphenol X, in the presence of at least one dyestuff, followed by the application of an additional composition which is anhydrous or in the form of an emulsion.
  • compositions which comprise a silicone resin as coating agent, for instance trimethyl siloxysilicate (INCI name) or polypropylsilsesquioxane (INCI name) resins, or which comprise silicone polymers such as silicone acrylate dendrimer copolymers (acrylates/polytrimethyl siloxymethacrylate copolymer - INCI name).
  • a silicone resin for instance trimethyl siloxysilicate (INCI name) or polypropylsilsesquioxane (INCI name) resins, or which comprise silicone polymers such as silicone acrylate dendrimer copolymers (acrylates/polytrimethyl siloxymethacrylate copolymer - INCI name).
  • Another known means of protecting the colour consists in using two-step makeup processes. In particular, they consist in depositing a first composition providing colour and then depositing a second composition onto the first, usually a transparent composition, in order to protect the first coloured layer.
  • a first composition providing colour
  • a second composition onto the first, usually a transparent composition
  • superposition of the layers is difficult because the application of the surface layer (top coat) must not damage the first layer (base coat).
  • the deposit resulting from this superposition is often considered too thick and therefore uncomfortable because it is too present on the skin and/or the lips.
  • the aim of the present invention is to propose compositions which afford excellent persistence of the expected cosmetic effects, notably the colour of makeup on the skin and the lips, which are resistant to mechanical friction, to meals, to water, to sweat and perspiration, to sebum, to oil, or even to cleaning products, notably makeup-removing products, such as certain micellar waters, or makeup-removing wipes, for example.
  • the aim of the present invention is to propose compositions and application processes which afford persistence of the expected cosmetic effects, notably the colour of the makeup, combined with an acceptable level of comfort.
  • the skin refers to the skin of the face (cheeks, eyelids, eye contour), of the body and of the hands.
  • compositions for making up and/or caring for the skin and/or the lips according to the invention are cosmetic compositions. This means that they advantageously comprise a physiologically acceptable medium.
  • physiologically acceptable means compatible with the skin and/or the lips, which has a pleasant colour, odour and feel, and which does not cause any unacceptable discomfort (stinging or tautness) liable to discourage the consumer from using this composition.
  • hydrogen bonding interaction means an interaction involving a hydrogen atom of one of the two reagents and an electronegative heteroatom of the other reagent, such as oxygen, nitrogen, sulfur and fluorine.
  • the hydrogen bond(s) are formed between the hydroxyl function(s) (OH) of the reactive phenol group(s) of the polyphenol X and the hydroxyl group(s) of the compounds Y that are capable of reacting by hydrogen bonding with the polyphenol X.
  • room temperature means 25°C.
  • atmospheric pressure means 760 mmHg, i.e. 1,013.10 5 pascals.
  • the polyphenols X that may be used according to the present invention include in their structure at least two different phenol groups.
