专利说明:
The present invention relates to a process for the cosmetic treatment of keratin materials using an acrylic polymer of maleic anhydride, as well as a kit for carrying out said process, and certain novel polymers. Cosmetic products often require the use of film-forming polymer to obtain a deposit of the product on keratin materials having good cosmetic properties. In particular, it is necessary that the film-forming deposit exhibits good behavior, in particular that the deposit does not transfer when in contact with the fingers, the clothing, a glass, a cup, as well as good holding in contact with the water, especially rain or when showering or sweating. The sebum of the skin can also damage the film-forming deposit. It is known to one skilled in the art to use polymers to obtain these properties of good behavior during the day. These polymers are of very different chemical natures and are generally carried either in a fatty phase or in an aqueous phase. Examples that may be mentioned include silicone resins, polyacrylates and latices. If these polymers effectively provide holding properties, particularly non-transfer, they may present discomfort, for example after the application of the product have a tacky appearance. There remains the need for polymers to obtain both good holding properties while maintaining a certain comfort in use. The inventors have discovered that a process for treating keratin materials using an ethylenic polymer of particular maleic anhydride combined with a particular amine compound makes it possible to obtain a deposit on keratin materials having good film-forming properties. The film-forming deposit obtained has good water resistance and also good resistance to oil (especially olive oil) and sebum. In addition, the film obtained has good flexibility to follow the deformations of the skin without deterioration. The particular ethylenic polymer is easily transportable in a hydrocarbon oil such as isododecane. In addition, the film-forming deposit has good properties of non-sticking and non-transfer, especially when touching the film with the fingers: the deposit obtained has good holding properties. In addition, when the ethylenic maleic anhydride polymer is formulated with a non-volatile oil (often used in make-up products) such as, for example, 2-octyl ethanol, the process according to the invention makes it possible to obtain a film-forming deposit. having good holding properties, no transfer, no stickiness, good resistance to water, oil, sebum. The ethylenic maleic anhydride polymer associated with said polyamine compound forms a film-forming deposit suitable for the makeup of skin or lips such as foundations, lipsticks.

Example 5 to 10 Comparative Cosmetic Evaluation of Makeup Compositions with Application in 2 Steps The 3 base coat make-up compositions (red lip gloss) containing the polymer of Example 1 or Example 2 and a top coat composition containing APTES described below were prepared. Each base coat composition was applied to an equivalent elastomeric skin support by depositing a wet 100 μm thickness and allowed to dry at room temperature (25 ° C) for 24 hours. Then, the top coat composition was applied to each dry base coat deposit by depositing a wet 100 μm thickness and allowed to dry at room temperature (25 ° C) for 24 hours. The state of the film obtained before (outside the invention) and after (invention) application of the top coat composition was then observed. The elastomer support was also manually deformed and the state of the film after this deformation was observed to determine its resistance to deformation. The strength of the obtained film was evaluated by separately applying 0.5 ml of water, 0.5 ml of olive oil and 0.5 ml of sebum; after 5 minutes of contact, the surface of the film was rubbed with a cotton pad and then the condition of the film (degraded or non-degraded aspect of the film) was observed It was also evaluated the stickiness of the film and its ability to transfer or not by touching the film with the finger The assessment was made as follows: +++: Cosmetic property evaluated high performance ++: evaluated cosmetic property moderately efficient +: evaluated cosmetic property not performing o: cosmetic property evaluated not performing The following results were obtained: The results obtained show that the deposits resulting from the application of the polymer 1, then of the apt (Examples 6-10) and those resulting from the application of the polymer 2 with the 2-octyldodecanol (Example 8) form a film homogeneous non-sticky and non-finger-transferring, and resistant to deformation, water, oil and sebum while the sole application of polymer 1 (Examples 9) or polymer 2 (Example 7) forms a deposit much more sticky and transferring on the finger and having a bad resistance to oil and sebum.

The cosmetic properties of the film obtained according to the tests described previously in Examples 5 to 10 were evaluated. The following results were obtained: The results obtained show that the deposit resulting from the application of the polymer 2 mixed with the Aptes, without or with 2-octyl dodecanol (Examples 16, 18, 20) forms a homogeneous film that is non-sticky and does not transfer to the finger. and resistant to water, oil and sebum while the sole application of Polymer 2, without or with 2-octyldodecanol (Examples 15, 17, 19) forms a much more tacky deposit and transfer on the finger and having poor resistance to oil and sebum. Thus, the non-sticky and non-contacting aspect of the film, as well as the resistance of the film in contact with water, olive oil and sebum, are significantly improved with the application of the composition. containing the polymer of Example 2 and the APTES. The composition of lipstick (Examples 16, 18) applied to the lips thus makes it possible to obtain a makeup that is non-tacky, non-transferable and resistant to oil and sebum, thus having good strength.
