Definitions

  • a cosmetic composition comprising, in a cosmetically acceptable medium, at least one film-forming polymer with certain elastomeric characteristics.
  • Also provided is a method of styling the hair comprising applying the cosmetic compostion to the hair.
  • Styling composition refers to any type of hair-dressing composition that can be used for effecting styling.
  • Hair care products for hair fixing that are most widely available on the cosmetics market include spray compositions in aerosols or pump-action bottles such as lacquers, sprays or mousses, for example, constituted of a solution that can be alcoholic or aqueous-alcoholic and of a film-forming polymer that can be water-soluble or alcohol- soluble, mixed with various cosmetic additives, or alternatively products that are to be applied by hand, such as gels, creams, pastes and waxes.
  • these hair styling formulations may not give the hairstyle satisfactory resistance to the various natural everyday movements such as walking, movements of the head or gusts of wind.
  • these compositions may give the hair a sensation of stiffness, the so-called "helmet effect”.
  • Styling products also include the styling shampoos, which can offer the benefit of combining washing of the hair while permitting shaping of the hair during drying, saving time for the increasingly busy user.
  • the polymers used conventionally for the formulation of hair styling products can be cationic, anionic, amphoteric or non-ionic film-forming polymers, which may lead to the formation of films that can be hard and brittle to a varying degree.
  • the percentage elongation at break measured on the film may be low, e.g., generally less than 2%, and the hairstyle may not be long- lasting.
  • these polymers have been mixed with plasticizers, providing films that can be more flexible and less brittle. These films can be quite deformable, and after deformation, they may only regain their initial form to a slight extent. Although the lasting properties of the hairstyle may be improved, they are still not satisfactory, since the form of the hairstyle changes, under the action of the stresses.
  • cosmetic compositions are being sought for the care and/or fixing of the hairstyle which can give the hair, in addition to long-lasting fixing, good cosmetic properties, notably conditioning of the hair conferring at least one of good disentangling properties, softness and a pleasant, non-sticky appearance, ease of use and low risk in use.
  • a cosmetic composition comprising, in a cosmetically acceptable medium, at least one film-forming elastomehc, anionic polyurethane (A), wherein the at least one film-forming elastomeric, anionic polyurethane (A) comprises:

  • composition according to the disclosure provides conditioning of the hair.
  • Also provided is a method of styling the hair comprising applying this composition to the hair.

  • the film-forming elastomeric, anionic polyurethane (A) can be partially or totally neutralized or over-neutralized with inorganic or organic bases, for example, with soda and/or triethylamine, in an amount making it possible to obtain, for example, a degree of neutralization of the anionic functions of the polymer from 0 to 150%, such as from 50 to 100%.
  • the "degree of neutralization to 150%” is obtained with an amount of inorganic or organic base equal to 1.5 times the amount of base required to obtain the degree of neutralization to 100%.
  • the film-forming elastomeric, anionic polyurethane (A) is provided in the form of a salt composed of two parts: one anionic polyurethane and a cationic ion, mineral or organic.

  • film obtained by drying at room temperature (24°C ⁇ 2°C) and at a relative humidity of 48% ⁇ 5% means the film obtained, in these conditions, from a mixture comprising 6% of active substance (a.s.) of film-forming elastomeric polyurethane (A), in a solvent (S).
  • the amount of active substance is understood as being relative to the total weight of solvent (S) and the amount of the mixture is suitable for obtaining, in a Teflon matrix, a film with thickness of 500 ⁇ m ⁇ 50 ⁇ m, after drying the mixture, with the drying being continued until there is no longer any change in weight of the film.
  • the measurements are generally performed after at least 10 days of drying.
  • the solvent (S) is a mixture ethanol/water comprising less than 30 % by weight of water.
  • the "elongation at break” and the "degree of recovery” are evaluated by means of the tests described below.
