Description

Description Title of the invention: AEROSOL DEVICE BASED ON ANIONIC FIXING POLYMER, DIRECT DYE, MONOALCOHOL AND A HALOGENATED HYDROCARBON

[0001] — The present invention relates to an aerosol device comprising a composition for treating keratin fibers such as hair comprising at least one anionic fixing polymer, at least one direct dye, at least one monoalcohol and at least less a halogenated hydrocarbon propellant and a treatment process using implement said composition. Technical field

[0002] — It is well known that hair is sensitized or weakened to varying degrees by the action of atmospheric agents and in particular light, of certain cosmetic treatments such as shampoos.

[0003] = We also know that light in particular tends to attack color natural hair color as well as artificial hair color from dyed or bleached hair. Hair color gradually fades or turns into unattractive shades or unwanted.

[0004] — Indeed, bleached hair is often weakened and porous, so that over time over time, they tend to lose their pigmentation and show yellow highlights / unsightly orange. Likewise light-colored hair, especially hair white or gray may have unsightly yellow / orange reflections.

[0005] — Thus, the aim of the present invention is to develop a treatment device keratin fibers such as hair allowing rapid application, and homogeneity of the composition on the keratin fibers leading to neutralization yellow and / or orange highlights in the hair throughout the treated hair, having good cosmetic properties in terms of softness or suppleness of the hair as well as good hair shaping properties and / or maintaining the hairstyle. Furthermore, the device according to the invention leads to a treatment that transfers little or nothing to skin or textiles once dried. Statement of the invention

[0006] This aim is achieved with the present invention which relates to an aerosol device including: - at least one pressurized container comprising: a) at least one composition comprising: 1) at least one anionic fixing polymer, (ii) at least one direct dye, and (ii) at least one C2-C4 monoalcohol, and, b) at least one propellant chosen from halogenated hydrocarbons, and, - a means for delivering the composition. The invention also relates to a method for neutralizing yellow and / or orange highlights in keratin fibers such as hair, previously bleached and / or natural, comprising the application to said fibers of a composition delivered from a device as defined above. By using the aerosol device according to the invention, uniform and chromatic neutralization is quickly and easily obtained on keratin fibers, such as hair, over the entire head of hair. In addition, the hair is softer to the touch and more supple. This treatment has the advantage of not being rinsed and not using water. In addition, this composition has good transfer resistance and deposition on supports with which the composition is brought into contact, such as skin and / or clothing, is limited. The present invention also relates to a method for shaping hair and / or maintaining the hairstyle, comprising a step of applying the composition to the hair, dry or wet, said composition being left unrinsed. Preferably, the composition is applied to keratin fibers such as light-colored hair (blonde or white), natural or bleached. It also relates to the use of the composition for shaping the hair and / or maintaining the hairstyle. By "neutralization of yellow and / or orange reflections" we mean masking unsightly yellow and / or orange reflections, i.e. modifying the color to make it more natural (close to a natural blond or white), in particular by varying the values ​​of the parameters a* (green red axis) and / or b* (blue yellow axis) of the CIELab colorimetric system The invention is not limited to the illustrated examples.

Composition A was sprayed for 5 seconds on each of the 2 sides of strands of bleached hair (alkaline solubility 50) weighing 2.7 g, at a distance of 20 cm. After drying, colorimetric measurements were performed using a spectrocolorimeter (Spectrocolorimeter Konica-Minolta -Post FR-C-MCI-0788) (illuminant D65, angle 10°, specular components included) in the CIELab system. In this system, a* represents the green-red axis, b* represents the blue-yellow axis. The chromaticity C* is calculated according to the formula: C*#= (a*2+4b# M2 The lower the value of C*, the lower the chromaticity, and the less yellow and / or orange reflections are visible: [Tables 2] I Before application of the composition |26.0 A After 1 application of the com- 22.0 composition A The value of C* is significantly lower after application of composition A: the color is less chromatic. We also visually notice that unsightly yellow and / or orange reflections are significantly reduced and that bleached hair has a more natural visual appearance. The product is distributed evenly along the strands, making the color more uniform. In addition, the hold is natural and allows the hairstyle to hold.
