Independent claims are included for: (1) a cosmetic coating process of the skin and/or lips, comprising applying at least a layer of the first composition, and a layer of the second composition, to the skin and/or lips; (2) a process for make-up and/or cleansing of make-up coat formed by application of the first and second compositions on the skin and lips, comprising applying a make-up removing composition and/or cleansing agent comprising an aqueous phase and a sequestrant of complexing agent in a medium, on the make-up coat; and (3) a cosmetic kit comprising first composition, second composition, and make-up composition and/or cleansing composition.

Description

The present application relates to a cosmetic kit comprising a compound based on alginic acid, and a complexing agent of said compound.

The compositions according to the invention may be independently of one another makeup compositions or compositions for the care of keratin materials, in particular skin and lips, and preferably make-up compositions. The makeup composition may be a lipstick makeup product (lipstick), a foundation, an eyeshadow, a blush, a concealer, an eyeliner, a body makeup product.

The care composition may be a product for the care of the skin of the body and the face, in particular a sun product, a product for coloring the skin (such as a self-tanner).

The compositions of lipstick and foundation are commonly used to bring an aesthetic color to the lips or to the skin, especially to the face. These makeup products generally contain fatty phases such as waxes and oils, pigments and / or fillers and possibly additives such as cosmetic or dermatological active ingredients.

These compositions, when they are applied to the skin, have the disadvantage of transferring, that is to say of being deposited at least in part, leaving traces, on certain supports with which they can be put in contact with each other. and especially a glass, a cup, a cigarette, a garment or the skin. It follows a poor persistence of the applied film, requiring regular renewal of the application of the foundation composition or lipstick. Moreover, the appearance of these unacceptable traces especially on the blouse collar can exclude some women from the use of this type of makeup.

We therefore seek make-up compositions for the lips and the so-called non-transfer skin which have the advantage of forming a deposit which does not deposit, at least in part, on the supports with which they are put in contact (glass, clothing The known non-transferable compositions are generally based on silicone resins and volatile silicone oils, but these compositions have the disadvantage of leaving on the skin and the lips, after evaporation, volatile silicone oils. , a deposit giving the user a feeling of drying and tugging: the makeup deposition becomes uncomfortable over time. In addition, some silicone resins can form a sticky makeup deposit and thus make the makeup even more uncomfortable.

In addition, these compositions often require the use of a particular makeup remover, which is impractical for the user.

The inventors have discovered that the use of compositions comprising pigments and a compound based on alginic acid capable of crosslinking in the presence of a complexing agent makes it possible to obtain on the skin and the lips a film of good behavior, in particular water resistant, which transfers little or no, comfortable over time. and the removal of makeup is easily done in the presence of a chelating agent of said complexing agent.

A first object of the present application is a skin and / or lip coating kit comprising: a first composition comprising an aqueous phase, pigments and at least one compound based on alginic acid, and a second composition comprising a complexing agent of said compound.

A second object of the present application is a cosmetic process for coating the skin and / or the lips consisting in applying to the skin and / or the lips: at least one layer of at least one first composition comprising an aqueous phase, pigments, at least one compound based on alginic acid, then - at least one layer of at least one second composition comprising a complexing agent of said compound.

The terms first and second composition do not condition the order of application of said compositions on the skin and lips.

Preferably, at least one layer of the first composition and then at least one layer of the second composition are applied to the skin and the lips.

The kit according to the invention makes it possible to obtain a deposit, in particular a makeup deposit, on keretic substances, in particular on the skin or the lips, which has good properties of no transfer, no sensation of drying, tugging or sticky: the deposit thus obtained is comfortable over time for the user.

Furthermore, the coating or film formed after application of the first and second compositions described above can be easily removed using a composition comprising a chelating agent of the complexing agent.

Therefore, according to another aspect, the present invention also relates to a method of removing make-up and / or cleaning makeup films formed by the application, on the skin and the lips, of a first composition comprising a phase aqueous, pigments, at least one compound based on alginic acid, and a second composition comprising a complexing agent of said compound, the method comprising at least one step of applying to said makeup films, a composition removing makeup and / or cleaning comprising, in a physiologically acceptable medium, an aqueous phase and at least one sequestering agent of said complexing agent.

Finally, the subject of the invention is also a composition comprising an aqueous phase, pigments, at least one compound based on alginic acid and a complexing agent for said compound.

The mobile of the texturometer is moved at a speed of 0.5 mm / s, then penetrates into the wax to a depth of penetration of 2 mm. When the mobile penetrated the wax to the depth of 2 mm, the mobile is held stationary for 1 second (corresponding to the relaxation time) and then removed at a speed of 0.5 mm / s. During the relaxation time, the force (compression force) decreases sharply until it becomes zero and then, when the mobile is removed, the force (stretching force) becomes negative and then increases again to the value 0.
