Cosmetic composition comprising at least one specific cationic polymer and at least one fatty acid ester in C8-C24 and oxyethylenated sorbitan comprising 2 to 10 oxyethylene patterns, and cosmetic treatment method using said composition

0001The present invention relates to a cosmetic composition for the treatment of keratin materials, preferably human and more particularly the hair, comprising in a cosmetically acceptable medium, at least one specific cationic thickening polymer and at least one fatty acid ester at C₈-VS₂₄ and oxyethylene sorbitan comprising 2 to 10 oxyethylene units. The present invention also relates to a cosmetic treatment process for the hair and scalp using said cosmetic composition.

0002For the cleaning and / or washing of keratin materials such as the hair, the use of detergent compositions (such as shampoos) based essentially on conventional surfactants of the type in particular anionic, nonionic and / or amphoteric, but more particularly of the anionic type, is common. These compositions are applied to wet hair and the foam generated by massage or friction with the hands allows, after rinsing with water, the elimination of the various soils initially present on the hair or the skin.

0003In addition to their possible washing properties and cosmetic qualities, users are sensitive to the fact that hair compositions, in particular shampoos and conditioners, do not attack the skin or the eyes, this quality being particularly appreciated in shampoos for children. Indeed, the most effective shampoos can cause tingling in the eye when the diluted product flows into the ocular sphere, which frequently occurs in children. In addition, many of these shampoos cause, in people with sensitive skin, discomfort reactions such as redness, itching, tingling.

0004Thus, to remedy all of the drawbacks described above, it is known to use C fatty acid esters₈-VS₂₄ and oxyethylene sorbitan comprising from 2 to 10 oxyethylene units as nonionic surfactants in hair compositions.

0005However, the compositions comprising these esters of oxyethylenated fatty acids do not generally have satisfactory qualities of use, in particular in terms of viscosity and / or distribution on the hair. Indeed, these oxyethylenated fatty acid esters most often make the compositions too thick, thus hindering their flow and / or their distribution on the hair due to the fact that there are significant chemical interactions between these oxyethylenated fatty acid esters. and other compounds such as conditioning agents present in these compositions.

0006In addition, these compositions based on esters of oxyethylenated fatty acids have an inhomogeneous texture and change substantially over time under normal storage conditions as a function of temperature, in particular in terms of their viscosity and their visual appearance. Thus, these compositions have a cloudy visual appearance as well as a continuous texture at 45 ° C under normal storage conditions.

0007Furthermore, in the case where these compositions based on oxyethylenated fatty acid esters also comprise anti-dandruff agents or agents producing a pearly, iridescent, moire or metallized appearance or effect such as cyclodextrin, these compositions are not still sufficiently stable.

0008There is therefore a real need to develop cosmetic compositions containing C fatty acid esters₈-VS₂₄ and of oxyethylenated sorbitan comprising from 2 to 10 oxyethylene units which do not have all of the drawbacks described above, that is to say which in particular have good properties of use, a satisfactory visual appearance and which are stable over time while providing satisfactory cosmetic properties to keratin materials, in particular to the hair and scalp.

0009The Applicant has discovered, surprisingly, that it was possible to formulate compositions for the cosmetic treatment of keratin materials, having the desired properties, by using in these compositions at least one C fatty acid ester.₈-VS₂₄ and oxyethylenated sorbitan comprising from 2 to 10 oxyethylene units and at least one specific cationic thickening polymer, defined below.

0010Indeed, it has been found that the use of said cationic polymer in the compositions of the present invention makes it possible to improve the properties of use, in particular in terms of viscosity, the stability as well as the texture of cosmetic products and in particular of shampoos and conditioners based on C fatty acid esters₈-VS₂₄ and of oxyethylenated sorbitan comprising from 2 to 10 oxyethylene units while conferring on keratin materials and in particular on hair satisfactory cosmetic properties, for example at the level of disentangling, flexibility, malleability, bulking and in particular at shine.

0011The compositions thus obtained have good usage properties, that is to say that these compositions can flow and be distributed more easily over the whole of the hair.

0012Furthermore, the storage stability of the compositions according to the invention is also improved both at room temperature (20-25 ° C) and at 45 ° C, especially in terms of their visual appearance and their viscosity. By “stable” within the meaning of the present invention is meant that the visual appearance as well as the viscosity of these compositions do not change appreciably over time under normal storage conditions, for example during the 12, preferably 24 and more preferably 30 months at room temperature following their manufacture or for example during the 2 months at 45 ° C. which follow their manufacture.

0013In addition, the compositions according to the present invention have a non-stringy and melting texture which allows them to be more easily absorbed on the surface of the hair or the skin. Such compositions also have a homogeneous texture.

0014Furthermore, the improved texture allows the product, once deposited, on the hair to remain for a certain time without flowing. This improved or even gelled texture makes it possible to use smaller quantities of products.

0015Finally, when the compositions have a pearlescent agent such as cyclodextrin, the compositions are stable over time and retain their pearly appearance.

0016The subject of the invention is therefore compositions for cosmetic treatment of keratin materials, preferably human, in particular keratin fibers, and more particularly hair, comprising in a cosmetically acceptable medium, one or more esters of C fatty acid.₈-VS₂₄ and oxyethylenated sorbitan comprising from 2 to 10 oxyethylene units and one or more specific cationic polymers as defined below.

0017It also relates to a process for the cosmetic treatment of keratin materials, preferably human, in particular keratin fibers, and more particularly of the hair, using the composition according to the invention.

0018It also relates to the use of the composition according to the invention as a shampoo or conditioner.

0019Other objects and characteristics, aspects and advantages of the invention will appear even more clearly on reading the description and the examples which follow.

0059By semi-hydrophobic vinyl surfactant monomer is meant in the sense of the present invention, a structure similar to an associative monomer, but which has a substantially non-hydrophobic end and thus does not confer associative property to the polymers.

The polymerization can be carried out by simple batch process, by controlled addition process, or else the reaction can be initiated in a small reactor and then the mass of the monomers can be added in a controlled manner into the reactor (seeding process). Generally, the polymerization is carried out at a reaction temperature between 20 and 80 ° C, even if higher or lower temperatures can be used.

The emulsion is deoxygenated using any known method, then the polymerization reaction is initiated by adding a polymerization catalyst (initiator) such as sodium persulfate, or any other suitable addition polymerization catalyst, as is well known in the field of polymers. The reaction mixture is stirred until the polymerization is complete, generally for a period varying from 4 hours to 16 hours. The monomer emulsion can be heated to a temperature between 20 and 80 ° C before the addition of the initiator, if desired. The amount of unreacted monomers can be removed by adding an additional amount of catalyst. The resulting polymer emulsion can be removed from the reactor and packaged for storage or use. Optionally, the pH or other physical or chemical characteristics of the emulsion can be adjusted before removing the emulsion from the reactor. Generally, the emulsion produced has a total solids content which varies between 10 and 40% by weight. Generally, the total amount of polymers in the emulsion obtained varies between 15 and 35% by weight, in general at most 25% by weight.
