Description

 COSMETIC COMPOSITIONS CONTAINING QUATERNIZED SILICONE AND NON - AMINO SILICONE AND USES THEREOF.

The present invention relates to new cosmetic compositions comprising in a cosmetically acceptable medium at least one non-amino silicone and at least one quaternary polyammonium silicone of type (AB) n, A being a polysiloxane block and B being a block comprising at least two ammonium groups. quaternary.

It is well known that hair which has been sensitized (ie damaged and / or weakened) to varying degrees under the action of atmospheric agents or under the action of mechanical or chemical treatments, such as coloring, bleaching and / or perms, are often difficult to untangle and style, and lack softness.

It has already been recommended in compositions for washing or caring for keratin materials such as the hair, the use of conditioning agents, in particular cationic polymers or silicones, to facilitate the disentangling of the hair and to impart softness and suppleness to them. However, the cosmetic advantages mentioned above are unfortunately also accompanied, on dry hair, by certain cosmetic effects deemed undesirable, namely a weighing down of the hairstyle (lack of lightness of the hair), a lack of straightening (non-homogeneous hair of root to tip).

In addition, the use of amino silicones for this purpose has various drawbacks. Because of their strong affinity for the hair, some of these silicones deposit in a significant way during repeated uses, and lead to undesirable effects such as an unpleasant, charged touch, a stiffening of the hair, and an interfibres adhesion affecting styling. These drawbacks are accentuated in the case of fine hair, which lacks nervousness and volume. It has also been recommended to improve the conditioning properties of hair products, to use cosmetic compositions for the treatment of hair containing the combination of a conditioning agent and a polyoxyalkylenated silicone of type (AB) n comprising at least one group. primary, secondary or tertiary amine, A being a polysiloxane block and B being a polyoxyalkylenated block comprising at least one primary, secondary or tertiary amino group. However, these compositions are not yet entirely satisfactory with regard to the smoothing and softness imparted to the hair. In addition, the hair is weighed down after repeated applications.

It has also been recommended to improve the conditioning properties of hair products to use cosmetic compositions for the treatment of hair containing a silicone of type (AB) n, A being a polysiloxane block and B being a block comprising at least two quaternary ammonium groups. . However, these compositions are not yet entirely satisfactory with regard to the properties of lightness imparted to the hair and of shine.

In summary, it turns out that the current cosmetic compositions containing conditioning agents are not completely satisfactory.

The Applicants have now discovered that the combination of a silicone comprising at least two quaternary ammonium groups with non-amino silicones overcomes these drawbacks.

Thus, following significant research carried out on the question, it has now been found by the Applicant that a composition comprising at least one silicone comprising at least two quaternary ammonium groups and one non-amino silicone, makes it possible to limit, even eliminate , the lack of shine, smoothness and softness of the hair, while retaining the other advantageous cosmetic properties which are attached to the compositions containing a silicone. Furthermore, the compositions of the invention applied to the skin, in particular in the form of a foaming bath or shower gel, provide an improvement in the softness of the skin.

Thus, according to the present invention, new cosmetic compositions are now proposed, comprising, in a cosmetically acceptable medium, at least one quaternary polyammonium silicone of type (AB) n, A being a polysiloxane block and B being a block comprising at least two quaternary ammonium groups and at least one non-amino silicone.

Another subject of the invention relates to the use of a quaternary polyammonium silicone of type (AB) n, A being a polysiloxane block and B being a block comprising at least two quaternary ammonium groups in, or for the manufacture of a cosmetic composition comprising a non-amino silicone. Another subject of the invention relates to the use of a composition comprising a quaternary polyammonium silicone of type (AB) n, A being a polysiloxane block and B being a block comprising at least two quaternary ammonium groups and a non-amino silicone for conditioning keratin materials.
