Abstract

The present patent application relates to a cosmetic composition, especially a hair composition, wherein it comprises, in a cosmetically acceptable medium, at least one cationic surfactant, at least one silicone chosen from amino silicones and vinyl silicones, at least one fatty alcohol, and at least one propellant.

Description

The present invention relates to novel cosmetic compositions, especially hair compositions, comprising at least one cationic surfactant, at least one silicone chosen from amino silicones and vinyl silicones, at least one fatty alcohol, and at least one propellant. The invention is also directed towards the use of these compositions in cosmetics, and in particular the use of these compositions as hair conditioners.

Standard hair conditioners in cream form allow good cosmetic properties to be obtained on the hair, such as smoothing, disentangling and gloss. However, the user occasionally has the sensation that his hair is heavy and lank, and easily becomes greasy again, most particularly if his hair is fine. In addition, the cream is occasionally difficult to measure out, and the user consumes a lot of product during each application.

The Applicant has just discovered, surprisingly, that foaming compositions comprising at least one cationic surfactant, at least one silicone chosen from quaternized or non-quaternized amino silicones, and vinyl silicones, at least one fatty alcohol, and at least one propellant, allow the drawbacks mentioned above to be overcome.

The Applicant has in particular found that these compositions are rich and creamy, and stay in the hand very well.

The Applicant has also found that it is not necessary to use these compositions in large amounts, and that, during application, they distribute and spread easily from the roots to the ends, and are particularly easy to rinse out.

Finally, the Applicant has found that these compositions give the hair good cosmetic properties, especially gloss, disentangling and smoothing, the hair is light and becomes greasy again less quickly, and the hair can be shaped very easily and durably.

One subject of the present invention is thus a cosmetic composition, especially a hair composition, wherein it comprises, in a cosmetically acceptable medium, at least one cationic surfactant, at least one silicone chosen from quaternized or non-quaternized amino silicones, and vinyl silicones, at least one fatty alcohol, and at least one propellant.

A subject of the invention is also an aerosol device comprising a composition according to the invention.

Another subject of the invention concerns a cosmetic haircare process using the compositions according to the invention.

A subject of the invention is also the use of the compositions according to the invention for the cosmetic treatment of the hair and the scalp.

Another subject of the invention is the use of the composition for washing and/or conditioning keratin materials such as the hair.

The alkyl radicals R₁₅ may be linear or branched, and more particularly linear.

Preferably, R₁₅ denotes a methyl, ethyl, hydroxyethyl or dihydroxypropyl radical, and more particularly a methyl or ethyl radical.
