Cosmetic composition comprising a particular combination of surfactants, a silicone, a cationic polymer, a fatty alcohol and a clay

The present invention relates to a cosmetic composition useful for washing keratin fibres, and in particular human keratin fibres such as the hair, which comprises one or more cationic and one or more amphoteric or zwitterionic surfactants, one or more silicones, one or more cationic polymers, one or more fatty alcoho ls and at least one clay, preferably kao linite, even better kaolin.

The invention also relates to a cosmetic process for washing keratin fibres using such a composition.

Finally, the invention relates to the use of such a composition for washing keratin fibres.

It is common practice to use detergent cosmetic compositions such as shampoos and shower gels, based essentially on surfactants, for washing keratin materials such as the hair and the skin. These compositions are applied to the keratin materials, which are preferably wet, and the lather generated by massaging or rubbing with the hands or a toiletry flannel makes it possible, after rinsing with water, to remove the diverse types o f soiling initially present on the hair or the skin.

These compositions contain substantial contents of "detergent" surfactants, which, in order to be able to formulate cosmetic compositions with good washing power, must especially give them good foaming power.

The surfactants that are useful for this purpose are generally o f anionic, non ionic and/or amphoteric type, and particularly o f anionic type .

Admittedly these compositions have a good washing power, but the intrinsic cosmetic properties associated with them nevertheless remain fairly poor, owing in particular to the fact that the relatively aggressive nature of such a cleaning treatment can, in the long run, lead to more or less pronounced damage to the keratin fibres, this damage being associated in particular with the gradual removal o f the lipids or proteins contained in or on the surface of said fibres.

Such damage to the hair leads to increased hair breakage in particular during combing.

Thus, there is a real need to provide compositions for washing keratin fibres, and in particular human keratin fibres, that do not have the drawbacks described above, and in particular which are milder than those of the prior art, and lead to a reduction o f hair breakage, in particular a reduction the breakage that occurs during combing after the shampoo .

There is also a need to provide compositions containing reduced amounts of anionic surfactants .

The composition should also have good detergent properties , and present a good tolerance especially with respect to the skin, mucous membranes, the scalp and the eyes .

Such compositions should furthermore have good properties o f use such as good foaming properties, and enhance the cosmetic properties of the keratin fibres, namely by affording them so ftness, smoothness and disentangling.

The Applicant has now discovered that a cosmetic composition comprising one or more cationic and one or more amphoteric or zwitterionic surfactants, one or more silicones, one or more cationic polymers, one or more fatty alcoho ls and a clay, makes it possible to achieve the obj ectives outlined above.

Thus, the subj ect of the invention is especially a cosmetic composition comprising :

- one or more cationic surfactants,

- one or more amphoteric or zwitterionic surfactants,

- one or more silicones,

one or more cationic polymers,

- one or more fatty alcoho ls, and

- one or more clays. The composition according to the invention has very good cleaning properties . It especially provides a homogeneous foam which has a good persistence over time.

Furthermore, the foam formed from the composition according to the invention spreads easily and uniformly onto keratin fibres .

In addition, the composition according to the invention leads to improved cosmetic properties, and especially affords good conditioning o f keratin fibres such as the hair, including when these fibres are sensitized. Indeed, the composition o f the invention provides, for instance, smoothness, so ftness and disentangling to the hair. The fibres are easy to disentangle without substantial breaking thereo f.

The invention also relates to a cosmetic process for washing keratin fibres using this composition.

Finally, the invention relates to the use of such a composition for washing keratin fibres.

Other subj ects, characteristics, aspects and advantages o f the invention will emerge even more clearly on reading the description and the example that follows.

In that which fo llows and unless otherwise indicated, the limits of a range of values are included within this range, in particular in the expressions "of between" and "ranging from ... to

Moreover, the expression " at least one" used in the present description is equivalent to the expression "one or more" .
