Definitions

  • TITLE SOLID COMPOSITION COMPRISING A CATIONIC SURFACTANT, TWO STARCHES, A LIQUID FATTY SUBSTANCE AND A SPECIFIC AMOUNT OF WATER
  • the present invention relates to a solid composition intended in particular for the cosmetic treatment, and more particularly the care, of keratin fibres, notably human keratin fibres such as the hair, and which comprises at least one cationic surfactant, at least two starches, at least one liquid fatty substance and a specific amount of water.
  • the invention also relates to a packaging article containing said solid composition, and also to cosmetic processes for treating keratin fibres, in particular human keratin fibres such as the hair, using said solid composition or said packaging article.
  • the invention also relates to the use of said solid composition or of said packaging article for the cosmetic treatment, preferably the care, of keratin fibres, in particular human keratin fibres such as the hair.
  • products for caring for (or conditioning) keratin fibres are generally intended to condition said fibres in order to give them good cosmetic properties.
  • Conventional products, such as conditioners are usually in more or less thickened liquid form.
  • these products may have various drawbacks, and may notably prove to be difficult to measure out.
  • Conditioners in powder or particle form may lose fluidity during storage due to the agglutination of the individual solid particles with each other, which may have a negative impact on the working qualities.
  • formulations may also not be entirely satisfactory in terms of cosmetic performance qualities, notably in terms of suppleness, feel, softness, disentangling, smoothness and sheen.
  • compositions in solid form which has an improved environmental profile, i.e. which requires little water throughout its use.
  • the composition must not only be easy to take up and break down easily, but must also rinse out quickly without leaving residues on the keratin fibres.
  • solid compositions notably in powder or particle form, they must not agglutinate together on storage, so as not to deteriorate the working qualities.
  • composition must also afford good cosmetic properties, notably in terms of suppleness, feel, softness, coating, sheen and disentangling.
  • a solid composition comprising at least one cationic surfactant, at least two starches, at least one liquid fatty substance and water in a particular content makes it possible to achieve the objectives presented above, and notably to propose a composition in solid form which combines good conditioning power, without, however, requiring large amounts of water.
  • One subject of the present invention is an anhydrous solid composition
  • an anhydrous solid composition comprising: i) one or more cationic surfactants, ii) two or more than two starches, iii) one or more liquid fatty substances and iv) from 0.1% to 9% by weight of water, relative to the total weight of the composition.
  • Said solid composition may more particularly be a cosmetic composition, notably a hair composition, and advantageously, a hair conditioning composition.
  • the particular combination of the compounds of the invention makes it possible to obtain a solid composition that is easy to take up, to handle and to measure out.
  • the composition thus obtained has a cohesion or granulation such that the uptake and measuring-out properties are improved, while at the same time avoiding undesired agglomerates which have a negative impact on the working qualities.
  • the composition can then be packaged in single-dose form, which is a form that is particularly advantageous, for example, when travelling or performing a sporting activity (lightened bags, limited risks of leakage, reduced waste).
  • this composition breaks down rapidly on contact with water and makes it possible readily and quickly to obtain easy spreading and uniform distribution over the keratin fibres comparable to those of a conventional liquid conditioner composition.
  • composition according to the invention also makes it possible to obtain good coating of the keratin fibres, with a uniform and gliding finish.
  • the composition of the invention rinses out rapidly without leaving unpleasant residues on the fibres and gives them a natural, clean feel after rinsing.
  • Fibres treated with the composition of the invention have good cosmetic properties, notably in terms of softness, suppleness and feel. They also have good strand separation and are thus easier to disentangle.
  • a subject of the present invention is also a process for the cosmetic treatment, notably for the care, of keratin fibres, in particular human keratin fibres such as the hair, comprising the application to said keratin fibres of a solid composition as defined below, the solid composition being applied directly to said keratin fibres or after having been moistened beforehand with water.
  • the present invention also relates to the use of a solid composition as defined below for the cosmetic treatment, preferably the care, of keratin fibres, in particular human keratin fibres such as the hair.

  • This packaging article notably solves the problems of measuring out of the solid composition. It also facilitates its storage and transportation. In particular, the packaging article of the invention affords better protection of the composition against moisture.
  • the packaging article may also make it possible to obtain a final keratin fibre care composition that is more thickened in the hand, which may be in cream form, without lumps, without leaving residues on the hair after rinsing.
  • the packaging article may thus improve, notably facilitate, the distribution of the composition over keratin fibres.
  • the packaging article may make it possible to better control the dose of composition employed on keratin fibres, thus reducing the risks of waste.
  • the packaging article also makes it possible to minimize the risks of breaking down of the composition.
  • the invention also relates to the use of the above packaging article for the cosmetic treatment, preferably for the care, of keratin fibres, in particular human keratin fibres such as the hair.
  • the invention also relates to a process for the cosmetic treatment, notably for the care, of keratin fibres, in particular human keratin fibres such as the hair, comprising a step of using at least one packaging article as defined above.
