[0001] The present invention relates to a method for the care and / or makeup of keratinous materials. In particular, the present invention relates to a skin care method. STATE OF THE ART

[0002] The development of formulas dedicated to skin and / or lip care and / or makeup is ongoing. These formulas must have satisfactory properties in terms of application, such as ease of use, and also in terms of sensory properties, such as a non-greasy and non-sticky feeling after application.

[0003] A wide variety of cosmetic compositions are used to care for the skin, particularly to provide hydration. These compositions typically contain lipophilic moisturizing agents that inhibit water loss by occlusion. For example, efforts have been made to formulate compositions in the form of creams or emulsions. Thanks to the thick texture of these compositions, it is possible to provide the skin with a moisturizing sensation through occlusion.

[0004] However, these types of products are still not satisfactory.

[0005] Consumers experience an unpleasant greasy feeling after applying the product. In addition, due to the thick texture of the products, it is not easy to apply them evenly to the skin and the change in texture is not very good.

[0006] It is therefore always necessary to implement a skin care process which can provide a non-greasy and non-sticky sensation.

[0007] It is also desired that the composition used in the process be stable and that it can be applied easily. Summary of the invention

[0008] An objective of the present invention is to propose a method for skin care and / or makeup, the composition used in the method is stable and can be easily applied to the skin and can provide a non-greasy and non-sticky sensation.

[0009] Therefore, the present invention relates to a method for skin care and / or makeup, comprising the application to the skin of a composition comprising:

[0010] (i) at least one C14-C30 fatty alcohol;

[0011] (ii) more than 0.3% by weight of at least one anionic surfactant selected from sulfate of C14-C22 alkyl, relative to the total weight of the composition; and

[0012] (iii) at least one acrylic polymer.

[0013] Preferably, the composition used in the process of the present invention is in the form of an oil-in-water emulsion.

[0014] The composition used in the process of the present invention is easily applied evenly to the skin, without long massage with the fingers.

[0015] The composition used in the process of the present invention may have a non-greasy and non-sticky feel.

[0016] The composition used in the process of the present invention is stable, that is to say, it does not exhibit phase separation after storage for 1 month at 55 °C.
