FR 3 060 324 - A1 composition comprising at least two anionic surfactants, one non-surfactant

IONIC AND AN AMPHOTERIC SURFACTANT, AND AT LEAST ONE ANTI-DANDRUFF AGENT.

The present invention relates to a composition intended for the cosmetic treatment of keratin fibers, in particular of the hair, comprising at least two anionic surfactants, at least one nonionic surfactant, at least one amphoteric surfactant, and at least one dandruff agent.

The invention also relates to a process for the cosmetic treatment of keratin fibers, in particular for washing and / or conditioning the hair, using such a composition, as well as a use using said composition.

ι

The present invention relates to a composition intended for the cosmetic treatment of keratin fibers, in particular human keratin fibers such as the hair, comprising at least two distinct anionic surfactants, at least one nonionic surfactant, at least one amphoteric surfactant, and at least one anti-dandruff agent. The invention also relates to a method for the cosmetic treatment of keratin fibers using such a composition, as well as to a use using said composition.

In order to combat the formation of dandruff, numerous hair compositions containing one or more dandruff agents have been proposed in the prior art.

However, these anti-dandruff hair compositions are not necessarily entirely satisfactory and can still be improved, in particular concerning the deposition of anti-dandruff agents on the keratin fibers and the scalp in order to be optimal.

Furthermore, the anti-dandruff hair compositions of the prior art generally do not give complete satisfaction in terms of foaming power and / or in terms of cosmetic properties, generally expected for compositions for washing keratin fibers.

There is therefore a real need to develop anti-dandruff hair compositions intended for cleaning and conditioning keratin fibers which are capable of imparting improved cosmetic properties to the hair, after one or more applications, without loading or weighing down the hair, all by retaining a good washing power, in particular a good foaming power (abundant foam, generated quickly, of good quality) and satisfactory qualities of use (ease of spreading the composition on especially wet hair, good rinsability).

This object is achieved by the present invention which relates in particular to a cosmetic composition, preferably a hair composition, in particular intended for the cosmetic treatment of keratin fibers, in particular human keratin fibers such as the hair, comprising:

(i) one or more anionic surfactants chosen 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 dandruff agents.

It has been found that the composition according to the invention has a satisfactory foaming power. It provides an abundant foam, quickly generated, which spreads easily on the keratin fibers and which is easily removed on rinsing.

Some users of shampoos, in particular anti-dandruff shampoos, may have more or less sensitized hair, that is to say hair which is generally damaged or weakened by the action of external atmospheric agents such as light and bad weather, and / or the action of mechanical or chemical treatments such as brushing, combing, dyeing, bleaching, perms and / or straightening. Also, the composition according to the invention also makes it possible to improve the cosmetic properties imparted to keratin fibers, in particular to the hair, preferably sensitized. In particular, the composition according to the invention makes it possible to improve the disentangling, the flexibility as well as the feel of the hair, without a build-up effect.

Furthermore, the compositions according to the invention have a relatively non-aggressive character, their application in the long term to the hair fiber resulting in little damage linked in particular to the progressive elimination of the lipids or proteins contained in or on the surface of the latter. .

In addition, the composition according to the invention allows good deposition of dandruff agents on keratin fibers and the scalp, and thus makes it possible to obtain improved dandruff activity.

In addition, the composition according to the invention can confer cosmetic properties which are persistent in shampoos.

The composition according to the invention also has the advantage of being stable in storage both at room temperature (20-25 ° C) and at 45 ° C, especially in terms of its visual appearance and / or its viscosity.

By "stable" is meant within the meaning of the present invention a composition which, after two months of storage has no change in appearance, color, odor or viscosity.

Preferably, the composition according to the invention is non-coloring.

The term “non-coloring composition” is understood to mean, according to the present invention, a composition that does not contain a dye for keratin fibers such as direct dyes or oxidation dye precursors (bases and / or couplers). If present, their content does not exceed 0.005% by weight, relative to the total weight of the composition. Indeed, at such a content, only the composition would be tinted, that is to say that there would be no effect of coloring keratin fibers.

In what follows, and unless otherwise indicated, the limits of a range of values are included in this range, in particular in the expressions "between" and "going from ... to ...".

Furthermore, the expression "at least one" used in the present description is equivalent to the expression "one or more" and may be substituted for it.

Anionic surfactants

As indicated above, the composition according to the invention comprises at least one anionic surfactant of the alkyl (amido) polyoxyalkylenated carboxylic ether type (i) and at least one anionic surfactant (ii) different from the anionic surfactant (s) (i).

Thus, within the meaning of the invention, the cosmetic composition comprises at least two separate anionic surfactants.

The term “anionic surfactant” is intended to mean a surfactant comprising only anionic groups as ionic or ionizable groups.

In the present description, an entity is qualified as being anionic when it has at least one permanent negative charge or when it can be ionized into a negatively charged entity, under the conditions of use of the composition of the invention (medium , pH for example) and not comprising a cationic charge.

According to the definition B. alba corresponds to the old appellations Beggiotoa arachnoidea, B. gigantea, B. leptomiformis, B. minima, B. mirabilis du Bergey’s manual, 8th edition. We can also mention bacteria belonging to the genus Vitreoscilla, which we know is close and often difficult to discern from the genus Beggiatoa.
