[0001] The present invention relates to a process for caring for and / or making up keratin materials. In particular, the present invention relates to a process for caring for the skin.BACKGROUND ART
[0002] The development of formulations dedicated to caring for and / or making up the skin and / or lips, is permanent. Said formulations have to show satisfactory properties in terms of application, such as easy usage, and also in terms of sensory, such as non-greasy and non-sticky feeling after application.
[0003] A wide variety of cosmetic compositions have been used to care for the skin, in particular to provide moisturizing or hydration to the skin. These compositions typically contain lipophilic moisturizing agents that inhibit water loss via occlusion. For example, efforts have been made to formulate compositions in the form of creams or emulsions. Thanks to the thick texture of the compositions, it is possible to provide to the skin moisturizing feeling via occlusion.
[0004] However, these types of products are still not satisfying.
[0005] Consumers feel an unappealing greasy after application of the product. Moreover, due to the thick texture of the products, it is not easy to apply on the skin evenly and the texture change is not very good.
[0006] There is thus still a need for a process for caring for the skin, which can provide a non-greasy and non-sticky feeling.
[0007] It is also desired that the composition used in the process is stable and can be easily applied.SUMMARY OF THE INVENTION

[0011] (ii) more than 0.3 wt. %of at least one anionic surfactant selected from C14-C22 alkyl sulfate, 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 oil-in-water emulsion.
[0014] The composition used in the process of the present invention is easily applied evenly on the skin, without long term massage by fingers.
[0015] The composition used in the process of the present invention can present non-greasy and non-sticky sensory.
