Description

 Cosmetic treatment method using an anhydrous composition in the form of a film comprising a film-forming polymer and a conditioning agent

The present invention relates to a process for the cosmetic treatment of keratinous fibers, in particular human keratinous fibers such as the hair, consisting in using, on keratinous fibers which have been previously treated, an anhydrous cosmetic composition in the form of a water-soluble film. comprising at least one film-forming polymer and at least one conditioning agent in the presence of a liquid or an aqueous fluid. The invention also relates to an anhydrous cosmetic composition in the form of a water-soluble film comprising at least one film-forming polymer and at least one particular conditioning agent. The hair is generally damaged and weakened by the action of external atmospheric agents such as light and weather, and by mechanical or chemical treatments such as brushing, combing, dyeing, discoloration, permanent and / or straightening. For example, in the case of permanent or straightening, it has been observed that the quality of the hair is often altered. The essential consequences of this alteration are a reduction of their cosmetic properties, such as their brilliance, as well as a degradation of their mechanical properties, in particular a degradation of their resistance due to a swelling of the hair during the rinsing between step d application of a composition containing a reducing agent (reduction step) and the step of applying a composition containing an oxidizing agent (oxidation step). This degradation can also result in an increase in the porosity of the hair.

The hair is thus weakened and can become brittle during subsequent treatments such as brushings.

In the same way, the coloration or the discoloration, which are processes generally carried out in strongly alkaline medium, in the presence of hydrogen peroxide is another example of chemical treatment which generally leads to a significant degradation of the fibers.

Moreover, such treatments most often make the hair difficult to discipline, in particular they are difficult to disentangle or comb, and the hair, even abundant, have difficulty maintaining a good looking hairstyle due to the fact that the hair is lacking. vigor and nervousness.

Thus, to overcome all of the disadvantages described above, it may be particularly advantageous for a user to apply care products that can condition the hair as a result of these treatments, in particular to provide the body, lightness, softness and to improve their disentangling ability. These hair care products may in particular be in the form of gels, creams, lotions, serum or shampoos.

However, the use of these care compositions generally have the disadvantage of altering, reducing or even eliminating the effects conferred by the chemical treatments previously carried out which has the particular effect of reducing their behavior over time.

For example, the artificial colors of the hair made by a coloring treatment may fade due to the subsequent application of a care composition. Thus the reflections can be faded to lead to less bright colors and less aesthetic. In the case of a perm, the use of a care composition can alter or decrease the degree of curling of the hair. On the other hand, it may also be advantageous for a user to use a care composition following a conventional cosmetic treatment that does not damage the hair to give them additional cosmetic properties. Such The treatments may consist, for example, in the application of a fixing composition, a cream or a shampoo.

Finally, it may be particularly advantageous for a user to treat the hair successively with the aid of various care compositions in order to confer additional or complementary cosmetic properties or to reinforce the cosmetic properties conferred by a first treatment. care.

However, the successive use of these care compositions generally has the disadvantage of leading to an increase in the hair.

Thus, there is a real need to have a treatment method that is applied to hair that has been previously treated, does not have all the disadvantages described above, that is to say that does not alter the cosmetic effects related to previous hair treatments and which gives the hair additional or complementary satisfactory cosmetic properties.

Surprisingly and advantageously, the Applicant has just discovered that by carrying out a cosmetic treatment process consisting in applying to hair that has been previously treated, an anhydrous cosmetic composition in the form of a water-soluble film comprising a water-soluble or water-dispersible film-forming polymer and a conditioning agent in the presence of an aqueous liquid or a fluid comprising water vapor, it was possible not only to maintain the effects provided by the previous hair treatments but also to give the hair additional or additional cosmetic properties without weighing them down, such as, for example, shine, smoothing, detangling or a styling effect. This method makes it possible to lead to a satisfactory cladding of the hair during the disintegration of the film in the presence of the fluid. The sheath obtained is in the form of a homogeneous deposit, smooth and has excellent adhesion to the hair which allows distribute the conditioning agent evenly over all the fibers to be treated.

The present invention is therefore obj and a cosmetic treatment method as described below. The present invention also relates to an anhydrous cosmetic composition in the form of a water-soluble film comprising at least one water-soluble or water-dispersible film-forming polymer and at least one particular conditioning agent.

Another object of the invention also consists in a multi-compartment device or kit comprising a first compartment comprising at least aqueous liquid and a second compartment comprising at least one anhydrous cosmetic composition in the form of a water-soluble film comprising at least one water-soluble film-forming polymer. or hydrodispersible and at least one conditioning agent.

Of course, the application of the fluid or the liquid may be repeated several times on the same fiber, each operation taking place according to a duration as indicated above.

The cosmetic composition in the form of a film and the aqueous liquid or the fluid comprising water vapor can be applied to the keratinous fibers simultaneously or sequentially. Preferably, the cosmetic composition in the form of a film is applied sequentially and the aqueous liquid or the fluid comprising water vapor on the keratinous fibers.

More particularly, the cosmetic composition in the form of a film is applied to the keratinous fibers, and then the aqueous liquid or the fluid comprising water vapor is applied to the fibers. Once these operations have been performed, it is preferable to massage the fibers in order to promote the disintegration of the film and the distribution of the conditioning agent thus released on all the fibers to be treated.

The production of a fluid comprising water vapor can be done using any apparatus known per se and provided for this purpose. However, according to the present invention, it is preferable to use a diffusion device (for example, a device generating an aqueous mist from ultrasound which is sold under the name MICROMIST by TAKARA BELMONT) or any other equivalent device, which In this case, it is particularly suitable (point, regular and homogeneous treatment of the fibers, without risk of overheating, with integrated post-cooling treatment).

According to one embodiment of the method, the first step of treatment of the keratinous fibers may consist of a dyeing or bleaching process, a method of fixing and / or maintaining the hairstyle, a permanent, a straightening, a method of care or a washing process.
