Description

COSMETIC COMPOSITIONS CONTAINING A BLOCK SILICONE

POLYETHER AND A POLYETHER SILICONE AND USES THEREOF.

The present invention relates to new cosmetic compositions comprising in a cosmetically acceptable medium at least one silicone comprising at least one terminal or pendant monovalent polyoxyalkylene group and at least one silicone of type (AB) n, A being a polysiloxane block and B being a block polyoxyalkylene and n being greater than or equal to 2.

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 polyether block silicones for this purpose has an insufficient cosmetic effect, in particular the conditioning effect. In document EP-A-684 041, 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 an insoluble conditioning agent and a polyoxyalkylenated silicone of type (AB) n, A being a polysiloxane block and B being a polyoxyalkylene block. However, these compositions are not yet entirely satisfactory with regard to the properties of lightness, volume 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 polyoxyalkylenated silicone. However, these compositions are not yet entirely satisfactory with regard to the disentangling, lightness and smoothing properties.

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 2 polyether polysiloxane blocks with polyoxyaikylenated silicones makes it possible to remedy these drawbacks.

Thus, following important 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 one terminal or pendant monoxy polyoxyalkylene group and at least one silicone of type (AB ) n, A being a polysiloxane block and B being a polyoxyalkylene block and n being greater than or equal to 2, made it possible to limit or even eliminate the lack of shine, lightness, volume, straightening 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 silicone comprising at least one monovalent, terminal or pendant polyoxyalkylene group and at least one silicone of type (AB) n, A being a polysiloxane block and B being a polyoxyalkylene block and n being greater than or equal to 2.

Another object of the invention relates to the use of a silicone comprising at least one monovalent polyoxyalkylene group, terminal or pendant in, or for the manufacture of a cosmetic composition comprising at least one silicone of type (AB) n, A being a polysiloxane block and B being a polyoxyalkylene block and n being greater than or equal to 2.

Another object of the invention relates to the use of a composition comprising at least one silicone comprising at least one monovalent polyoxyalkylene group, terminal or pendant and at least one silicone of type (AB) n, A being a polysiloxane block and B being a polyoxyalkylene block and n being greater than or equal to 2 for the conditioning of keratin materials.

The compositions can be packaged in various forms, in particular in vaporizers, pump-dispenser bottles or in aerosol containers in order to ensure application of the composition in vaporized form or in the form of foam. Such forms of packaging are indicated, for example, when it is desired to obtain a spray, a lacquer or a foam for the treatment of hair.

According to the invention, the compositions are prepared by mixing, with stirring, the various constituents.
