Description

Cosmetic composition comprising nonionic associative polymers and nonionic surfactants, and cosmetic treatment method

The present invention relates to a cosmetic composition, in particular a capillary composition, comprising at least one nonionic associative polymer and at least one particular nonionic surfactant, as well as a cosmetic treatment method using said composition.

Hair tends to lose some of its qualities under the action of factors such as natural regreasing, sweat, the elimination of dander, pollution or moisture in particular. The visual appearance and the feel of the hair can be degraded. Regreasing, for example, weighs down the hair, which then tends to pack. The hair may be more difficult to comb, and have a greasy shine or an unpleasant waxed touch.

It is known to clean the hair with shampoos which are generally aqueous compositions containing large amounts of surfactants, which are generally anionic surfactants, alone or in combination with amphoteric and / or nonionic surfactants. The total amounts of surfactants used generally exceed 10% by weight of active material, relative to the total weight of the cosmetic composition.

These shampoos based on significant amounts of anionic surfactants can cause discomfort such as tingling of the scalp or eyes when they come into contact with the shampoo.

Furthermore, these surfactants can alter, as and when applications, the cosmetic properties of the hair which leads to the need to also use conditioning agents such as cationic polymers, silicones or non-silicone oils.

In addition, the rinsing of cosmetic compositions with high surfactant content can often be long.

Finally, to avoid application dripping and especially eye drops, shampoos should generally be thickened; but their thickening may cause problems of stability of the composition.

In order to overcome these various problems, it has been proposed, for example by the application FR2935267, to add associative polymers to shampoo compositions, which makes it possible to reduce their content of conventional surfactants. From a certain concentration, these associative polymers have sufficient detergency to allow the cleaning of the hair in the presence of very small amounts of surfactants or even in the absence of these surfactants. However, the compositions thus obtained, even if they allow a detergency similar to that obtained with a conventional shampoo, still have insufficient foaming character; in addition, the cosmetic properties imparted to the hair are not yet completely satisfactory, in particular on dry hair.

The object of the present invention is to provide cosmetic hair compositions which overcome these drawbacks, and in particular capable of generating an adequate foam, both in quality and in quantity, and providing the hair with satisfactory cosmetic properties, especially on dry hair.

The subject of the invention is therefore a cosmetic composition, in particular a capillary, non-coloring composition comprising:

2 to 60% by weight relative to the total weight of the composition, of one or more associative nonionic polymers, and

one or more nonionic surfactants of C 12 -C 18 fatty chain type, polyoxyalkylenated having a number of alkylene oxide units ranging from 4 to 10.

The composition according to the invention is non-coloring. According to the present invention, the term "non-coloring composition" is intended to mean a composition which does not contain a dye for keratin fibers, such as direct dyes or oxidation dye precursors (bases and / or couplers). If they are 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, one would not observe staining effect of keratin fibers.

In the present description, the term "at least one" is equivalent to the term "one or more" and may be substituted therefor.

In the present description, the term "between" is equivalent to and may be substituted for "from"; in these expressions, the bounds are considered included.

Nonionic associative polymer

The composition according to the invention thus comprises one or more associative nonionic polymers.
