Definitions

  • the present invention relates to hair treatment compositions containing a combination of at least one particular amphiphilic cationic polymer with at least one film-forming and / or setting polymer selected from chitosan and its derivatives, the use of these agents for temporary shaping and / or care of keratin-containing fibers and aerosol hair sprays foams based on these agents.
  • all animal hair e.g. Wool, horsehair, angora hair, furs, feathers and products or textiles made from them.
  • the keratinic fibers are human hairs.
  • Corresponding temporary shaping agents usually contain synthetic polymers as the shaping component.
  • Preparations containing a dissolved or dispersed polymer can be applied to the hair by means of propellant gases or by a pumping mechanism.
  • hair gels and hair waxes are generally not applied directly to the hair, but distributed by means of a comb or hands in the hair.
  • the most important property of a composition for the temporary deformation of keratinic fibers is to give the treated fibers in the produced form the strongest possible hold. If the keratin fibers are human hair, it is also referred to as a strong hairstyle or the high degree of retention of the styling agent.
  • the hairstyle hold is essentially determined by the type and amount of the synthetic polymer used, but also an influence of the other constituents of the styling agent may be given. In addition to a high degree of hold, styling agents must meet a whole range of other requirements.
  • properties on the hair may be broadly subdivided into properties on the hair, properties of the particular formulation, eg properties of the foam, of the gel or of the sprayed aerosol, and of properties which affect the handling of the styling agent, whereby the properties on the hair are of particular importance. Particularly noteworthy are moisture resistance, low tackiness and a balanced conditioning effect. Furthermore, a styling agent should be universally applicable as possible for all hair types.
  • the polymers can be subdivided into cationic, anionic, nonionic and amphoteric film-forming and / or setting polymers.
  • the polymers when applied to hair, the polymers give a polymer film which, on the one hand, gives the hairstyle strong hold but, on the other hand, is sufficiently flexible not to break under stress. If the polymer film is too brittle, it results in the formation of so-called Filmpiaken, that is residues that detach during the movement of the hair and give the impression that the user of the corresponding styling agent would dandruff.
  • Object of the present invention was therefore to provide a means for temporary deformation and / or care keratinic fibers available, which is characterized by a high degree of hold or by a high care effect and in particular excellent handling during application to the keratin fibers has.
  • compositions achieved with this combination even have, in addition, a transparency that is visible to the naked eye.
  • a first subject of the present invention is therefore an agent for treating keratin-containing fibers, especially human hair, contained in a cosmetically acceptable carrier

  • Film-forming polymers are polymers which leave a continuous film on the skin, the hair or the nails when drying.
  • Such film formers can be used in a wide variety of cosmetic products, such as for example face masks, make-up, hair fixatives, hair sprays, hair gels, hair waxes, hair treatments, shampoos or nail varnishes.
  • Particular preference is given to polymers which have a sufficient solubility in water or water / alcohol mixtures in order to be present in completely completely dissolved form in the agent according to the invention.
  • the film-forming polymers may be of synthetic or natural origin.
  • film-forming polymers are understood as meaning polymers which, when used in 0.01 to 20% strength by weight aqueous, alcoholic or aqueous-alcoholic solution, are capable of depositing a transparent polymer film on the hair.
  • Firming polymers contribute to the maintenance and / or build-up of the hair volume and hair fullness of the overall hairstyle. These polymers are at the same time also film-forming polymers and therefore generally typical substances for shaping hair treatment agents such as hair fixatives, hair foams, hair waxes, hair sprays.
  • the film formation can be quite selective and connect only a few fibers.
