Invention Title: COSMETIC COMPOSITION COMPRISING AT LEAST ONE SILICONE/ACRYLATE COPOLYMER AND AT LEAST ONE CONDITIONING AGENT The following statement is a full description of this invention, including the best method of performing it known to me/us: lAk COSMETIC COMPOSITION COMPRISING AT LEAST ONE SILICONE/ACRYLATE COPOLYMER AND AT LEAST ONE CONDITIONING AGENT The invention relates to a cosmetic composition comprising at least one specific silicone/acrylate copolymer and at least one conditioning agent. The invention also relates to a cosmetic process, in particular a process for fixing 10 and/or holding the hairstyle by using the said composition, as well as to the use of this composition for the manufacture of a cosmetic formulation intended in particular for holding and/or shaping the hairstyle.

Among hair products, in particular those 15 intended for shaping and/or holding the hairstyle which are most widely available on the cosmetics market, there may be distinguished the spray compositions essentially consisting of a solution, usually an alcoholic or aqueous solution, and one or more materials.

When the compositions are intended for fixing and/or holding the hairstyle, these materials are generally polymeric resins, whose function is to form welds between the hairs, and these are also known as fixing materials, mixed with various cosmetic adjuvants. These compositions are generally packaged either in a suitable aerosol container placed under pressure with the aid of a propellant, or in a pumpdispenser bottle.

Hair gels and hair mousses which are generally applied to wet hair before blow-drying or setting the hair are also known. A drying or blowdrying operation is then carried out in order to shape and fix the hairstyle. These gels or mousses can also e contain polymeric resins.

:-.However, these hair compositions often have oooo 10 the drawback of adversely affecting the cosmetic properties of the hair. Thus, the hair can become coarse and difficult to disentangle, it can lose its o pleasant feel and appearance or it may lack body.

Styling compositions are thus sought which afford good 15 cosmetic properties, in particular in terms of oooo disentangling, softness and feel.

In addition, these hair compositions also have the major drawback of giving rise to a powdering effect. For the purposes of the present invention, the term "powdering" means the aptitude of the material obtained, by drying the hair composition, to form a powder after it has beenapplied to the hair. Needless to say, the powder falls on the user's shoulders or clothing, or it attaches to the comb or the brush, and this is a detrimental effect.

There is thus a need to find cosmetic compositions, in particular for styling the hair, which do not have the set of drawbacks mentioned above, and which in particular fix the hairstyle well, while at the same time affording good cosmetic properties without a powdering effect.

The Applicant has discovered, surprisingly and unexpectedly, that when specific silicone/acrylate copolymers are combined with certain conditioning agents, it is possible to obtain cosmetic compositions which satisfy the requirements expressed above.

One subject of the invention is a cosmetic 10 composition comprising, in a cosmetically acceptable i." medium, at least one silicone/acrylate copolymer and at least one conditioning agent, the silicone/acrylate copolymer being obtained by radical-mediated polymerization 15 of at least one ethylenically unsaturated monomer in the presence of at least one silicone derivative comprising oxyalkylene groups, and the conditioning agent being chosen from the group comprising cationic polymers, cationic or amphiphilic surfactants, organosiloxanes, linear or branched C 8 to C 300 hydrocarbons, linear or branched C 8 to C 30 fatty alcohols, esters of a C 8 to C 30 fatty acid and of a Ci to C 30 alcohol, esters of a Ci to C 7 acid or diacid and of a C 8 to C 30 fatty alcohol, and ceramides or ceramide analogues.

4 Another subject of the invention relates to a cosmetic hair process, in particular a process for fixing and/or holding the hairstyle using the said composition.

Yet another subject of the invention relates to the use of this composition for the manufacture of a cosmetic hair formulation which is intended in particular for holding and/or shaping the hairstyle.

The silicone/acrylate copolymers particularly 10 targeted by the present invention are those described in International patent application WO 99/04750.
