Description

USE OF AROMATIC POLYCARBOXYLIC ACID FOR PROTECTING COLOR FROM THE WASHING OF ARTIFICIALLY ARTIFICIENT KERATIN FIBERS; The invention relates to the use of one or more particular aromatic polycarboxylic acids as an agent for protecting the color vis-à-vis the washing of dyed keratin fibers by direct dyeing or by oxidation dye, in particular human keratin fibers and more particularly hair.

It is known to dye particularly human keratinous fibers and in particular the hair with dyeing compositions containing oxidation dye precursors, generally called oxidation bases.

These oxidation bases are colorless or weakly colored compounds which, when combined with oxidizing products, give rise to colored compounds by a process of oxidative condensation. It is also known that the shades obtained with these oxidation bases can be varied by combining them with couplers or color modifiers. The variety of molecules involved in the oxidation bases and couplers allows a rich palette of colors to be obtained.

It is also known to dye keratinous fibers by direct dyeing. The method conventionally used in direct dyeing consists in applying to the keratin fibers direct dyes which are colored and dyestuff molecules having an affinity for the fibers, allowing the fibers to be laid and then rinsed. This direct coloration may be optionally carried out in the presence of an oxidizing agent, it is then called direct lightening coloring.

The resulting colorings are particularly chromatic colorations that are however temporary or semi-permanent because the nature of the interactions that bind the direct dyes to the keratinous fiber and their desorption from the surface and / or the core of the fiber are responsible for their low dye power and their poor resistance to washes.

The artificial color of the hair provided by a direct coloring or oxidation treatment gradually fades due to repeated washing and leads in time to a fading of the hair coloring. The use of rinsed and rinsed care products marketed does not improve sufficiently the holding of the artificial color of the hair.

It is therefore necessary to develop means to protect the artificial color of the effect of repeated washing.

The Applicant has now surprisingly discovered that the use of one or more particular aromatic polycarboxylic acids makes it possible to protect the artificial color of the dyed keratin fibers by direct dyeing or oxidation dyeing in the presence of the washing. an oxidizing agent.

This discovery is the basis of the present invention. For the purposes of the invention, the term "oxidizing agent" means any compound having oxidizing properties and being different from oxygen in the air.

By human keratin fibers is meant hair, hair including a beard or mustache, eyelashes, eyebrows.

The term "keratin fibers" artificially dyed keratin fibers dyed by a direct dyeing process or by an oxidation dyeing process.

By washing is meant one or more applications on the keratinous fibers of an aqueous composition that is eliminated, most often a detergent such as a shampoo. This expression also includes swimming, especially at sea or in swimming pools.

The subject of the invention is therefore the cosmetic use of one or more aromatic polycarboxylic acids of formula (I) below: ## STR5 ## in which n is an integer greater than or equal to 3, preferably ranging from 3 to 6, X represents a hydrogen atom or an alkali metal, R denotes an aromatic radical comprising from 6 to 30 carbon atoms, said radical being optionally substituted,

As an agent for protecting against washing the color of artificially dyed keratin fibers, especially human keratinous fibers and more particularly hair.

Preferably, the keratinous fibers are dyed by oxidation dyeing, especially in the presence of one or more oxidizing agents. The invention also relates to a method for protecting the color vis-à-vis the washing of artificially dyed keratinous fibers, characterized in that it consists in applying to said fibers, one or more aromatic polycarboxylic acids of formula (I) or a composition comprising in a cosmetically acceptable medium one or more aromatic polycarboxylic acids of formula (I). Preferably, the keratinous fibers are dyed by oxidation dyeing in the presence of one or more oxidizing agents.

The aromatic polycarboxylic acid (s) of formula (I) may be introduced into the dye composition applied to the keratinous fibers. They can be introduced preferably into a composition applied before or after dyeing keratinous fibers. More preferably, the aromatic polycarboxylic acids of formula (I) are introduced into an applied composition after dyeing keratinous fibers.

In addition, the protection afforded by the treatment according to the invention is durable, that is to say not requiring frequent reapplications of the product.

Another subject of the invention relates to a dyeing process consisting in applying to the keratinous fibers, in particular human keratinous fibers and more particularly the hair, a direct dye composition (A) or an oxidation dye composition (A) during a sufficient time to develop the color, and to follow or precede this application by the application of a composition (B) containing in a cosmetically acceptable medium one or more aromatic polycarboxylic acids of formula (I). Preferably, the composition (A) is an oxidation dye composition in the presence of one or more oxidizing agents.

Another subject of the invention relates to a dyeing process consisting in applying to the keratinous fibers, in particular human keratinous fibers and more particularly the hair, a direct dye composition (A) or an oxidation dye composition (A) during a sufficient time to develop the color, said composition (A) comprising in a cosmetically acceptable medium one or more aromatic polycarboxylic acids of formula (I).

The treated locks are then subjected to a tenacity wash with shampoos compared to untreated colored locks. For this, the locks undergo 8 successive Dop Camomile shampoos with intermediate drying.

10 Evaluation of the protection

The color degradation after washings of the treated and untreated locks was visually evaluated against unwashed colored locks.

Spectro-colorimetric monitoring accompanies these evaluations. Measurements are made using the MINOLTA CM2022 spectrocolorimeter:

The degradation caused by the washes is expressed as AE AE (8 shampoos - 0 shampoo) = - q (AL * 2 + Aa * 2 + Ab * 2) The protection is then expressed by a difference in AE between the treated and non-treated locks. processed. Results:

After the washdown toughness test, there is a significant degradation of the color of the untreated colored locks.

It is surprisingly observed that after this same test, the use of the active ingredient 1 of the invention provides a significant protection of the color compared to untreated locks. These results are confirmed by colorimetric measurements which indicate a significant AE gain compared to the untreated lock after 8 shampoos.
