Description

Use of a washing composition comprising surfactants and cationic and / or amphoteric polymers in combination with a composition comprising anionic beneficial agents

The present invention relates to a method for the cosmetic treatment of keratin fibers, in particular human keratin fibers such as the hair, comprising applying sequentially, a washing cosmetic composition A comprising at least two distinct anionic surfactants, one or more nonionic surfactants , one or more amphoteric surfactants, and one or more cationic and / or amphoteric polymers, and a cosmetic composition B comprising one or more anionic beneficial agents.

It is known to dye keratin fibers and in particular human hair, with dye compositions containing direct dyes. The conventional dyes which are used are in particular dyes of the benzene nitro type, anthraquinones, nitropyridine, azo, xanthene, acridine, azine, triarylmethane or natural dyes.

These dyes can be nonionic, anionic, cationic or amphoteric. These dyes are colored or coloring molecules having an affinity for keratin fibers. These compositions containing one or more direct dyes are applied to the keratin fibers for a time necessary to obtain the desired coloration, then rinsed off. The resulting colorings are particularly chromatic colors which are however temporary or semi-permanent because the nature of the interactions which bind the direct dyes to the keratin fiber, and their desorption from the surface and / or from the core of the fiber are responsible for their low dye power and their poor resistance to light, washing, or perspiration.

Furthermore, the use of acid dyes generally results in coloring of the scalp which is undesirable.

In addition, in order to reach the desired dye level, it is often necessary to have a relatively long pause time (usually more than 10-15 minutes).

Acid dyes are interesting for coloring the hair because they are generally inexpensive. In addition, at the concentrations generally used, they have little or no sensitization. However, these dyes stain the scalp a lot. They are therefore used in low concentrations which does not always allow good coverage of gray hair.

There is therefore still room for improvement in this area, especially from acid dyes to provide fast, powerful, resistant dyes which respect the nature of the hair and which do not cause coloring of the scalp.

It is also desirable to protect the hair from light to maintain their cosmetic properties and respect their color, whether natural or artificial. This protection is generally carried out by means of compositions based on sun filters. However, these compositions cannot be rinsed without completely losing their effectiveness, when anionic sunscreens are used, or else they impart a very oily feel to the hair, in the case of nonionic filters.

However, the hair compositions intended in particular for coloring, conditioning or protecting the hair using anionic beneficial agents are not necessarily entirely satisfactory and can still be improved, in particular concerning the deposition of these anionic agents on the keratin fibers. , both in terms of quantity and persistence, in particular washing persistence.

There is therefore a real need to implement a process capable of improving the cosmetic performance of hair compositions, in particular by giving keratin fibers increased cosmetic properties, and this in a persistent manner.

The present invention aims to provide a use and a cosmetic treatment process for keratin fibers, in particular human keratin fibers such as the hair, making it possible to improve the performance of a composition comprising at least one anionic beneficial agent (called hereinafter composition B) by virtue of a combined effect between composition B and washing composition A applied before or after this composition B, in particular before.

By performance, we mean in particular:

- cosmetic (such as smoothing, flexibility, detangling), dyeing or protective performance (such as UV protection when applying the treatment, and

- long-term dye or protective cosmetic performance during the following shampoos.

The subject of the present invention therefore is a process for the cosmetic treatment of keratin fibers, in particular human keratin fibers such as the hair, comprising:

(iv) one or more amphoteric surfactants; and (v) one or more cationic polymers and / or one or more amphoteric polymers; and

(iv) one or more amphoteric surfactants; and (v) one or more cationic polymers and / or one or more amphoteric polymers; and

- at least one step (b) of application to said keratin fibers, of a cosmetic composition B comprising one or more anionic direct dyes.

The present invention also relates to the use of a washing cosmetic composition A, comprising (i) one or more anionic surfactants chosen, alone or as a mixture, from polyoxyalkylenated alkyl (amido) ether carboxylic acids and their salts; (ii) one or more anionic surfactants different from the polyoxyalkylenated alkyl (amido) ether carboxylic acid anionic surfactant (s) (i); (iii) one or more nonionic surfactants;

(iv) one or more amphoteric surfactants; and (v) one or more cationic polymers and / or one or more amphoteric polymers, in combination with a cosmetic composition B comprising one or more anionic beneficial agents as defined below, for obtaining a residual conditioning of said fibers keratin, in particular of flexibility, smoothing to the touch, disentangling, coloring and / or protection, in particular remaining at least 3 shampoos.

Preferably, the washing cosmetic composition A according to the use of the invention comprises (v) one or more cationic polymers and one or more amphoteric polymers.

The implementation of the invention allows in particular to obtain, upon application, the desired properties and in particular flexibility, smoothness, volume and an unloaded natural feel, coloring and / or protection. UV while keeping hair light and individual; this process particularly provides the hair with an improved combability. In the case of coloring with anionic direct dyes, the dye performance is improved compared to the usual; this can result in a reduced pause time and / or a lower concentration of anionic coloring agent in the composition, to reach the desired dye level. It has also been observed that these desired properties, obtained as a result of the implementation of the invention, are in particular persistent in shampoos.

Indeed, it has been found that the use of a washing composition A according to the invention could make it possible to improve the persistence of the packaging (or of the packaging properties) and / or of coloring and / or of protection provided by the composition.

Furthermore, it has also been found that the use of a washing composition A according to the invention has a relatively mild character, the application of the composition in the long term to the hair fiber causing little damage, in particular related to the progressive elimination of lipids or proteins contained in or on the surface thereof. In addition, the washing composition A according to the invention allows good deposition, or even good penetration, of the anionic beneficial agents on / in the keratin fibers and thus makes it possible to obtain an improved conditioning action.

The time which separates the application of the washing composition A from the application of the composition B according to the invention depends on the consumer's need to wash his hair and / or on the frequency with which he performs his shampoos. There is no particular constraint on this time, which can range from a few minutes (the application of washing composition A is immediately followed by the application of composition B) to a few days; this time can in particular range from 30 seconds to 7 days, for example from 1 minute to 4 days, better from 2 minutes to 3 days, or even from 5 minutes to 48 hours, even better from 10 minutes to 24 hours.
