Abstract

Kit for whitening a body surface of a user, comprising:
an oxidizing composition application device ( 12 ); wherein the kit comprises an activator sheet ( 14 ) which is movable independently of the oxidizing composition application device ( 12 ), the activator sheet ( 14 ) comprising an outer deformable substrate ( 50 ) intended to be applied on an oxidizing composition ( 34 ) placed on the skin of the user, the activator sheet ( 14 ) comprising an activator composition ( 52 ) carried by the outer substrate ( 50 ).

First claim

The invention claimed is:

1. A kit for whitening a body skin surface of a user, comprising:
an oxidizing composition application device;
an activator sheet which is movable independently of the oxidizing composition application device, the activator sheet comprising an outer deformable substrate intended to be applied on an oxidizing composition placed on the skin of the user, the activator sheet comprising an activator composition carried by the outer substrate;
wherein the oxidizing composition application device comprises an oxidizing sheet, which is movable independently of the activator sheet, the oxidizing sheet comprising an inner substrate, intended to be applied against the body surface of the user and an oxidizing composition carried by the inner substrate.

2. The kit according to claim 1 , wherein the outer substrate comprises at least one fibrous layer.

3. The kit according to claim 2 , wherein the outer substrate comprise at least one film layer laminated on the fibrous layer.

4. The kit according to claim 3 , wherein the activator composition is a solid, carried by the outer substrate.

5. The kit according to claim 3 , wherein the activator sheet comprises a binder attaching the activator composition to the outer substrate.

6. The kit according to claim 2 , wherein the activator composition is a solid, carried by the outer substrate.

7. The kit according to claim 2 , wherein the activator sheet comprises a binder attaching the activator composition to the outer substrate.

8. The kit according to claim 2 , wherein the activator sheet is a face mask capable of defining at least one central through opening, intended to receive a nose of the user, and at least two upper through openings for placing in front of the eyes of the user.

9. The kit according to claim 1 , wherein the activator composition is a solid, carried by the outer substrate.

10. The kit according to claim 9 , wherein the activator composition comprises a base, ammonia, an amine, a carbonate, a gluconate, a peroxide, an aminoacid and their salts, a zeolite, a silicate, or mixtures thereof.

11. The kit according to claim 10 , wherein the activator sheet comprises a binder attaching the activator composition to the outer substrate.

12. The kit according to claim 9 , wherein the activator sheet comprises a binder attaching the activator composition to the outer substrate.

13. The kit according to claim 1 , wherein the activator sheet comprises a binder, attaching the activator composition to the outer substrate.

14. The kit according to claim 1 , wherein the activator sheet is a face mask capable of defining at least one central through opening, intended to receive a nose of the user, and at least two upper through openings for placing in front of the eyes of the user.

15. The kit according to claim 1 , wherein the oxidizing composition comprises a peroxide, a persulfate salt, a perborate salt, a carbonate salt, a percarbonate salt or mixtures thereof.

16. The kit according to claim 1 , wherein the oxidizing composition is carried on the oxidizing sheet in a gel form, in an emulsion form, or in a liquid form.

17. The kit according to claim 1 , comprising a packaging having a first compartment for receiving the oxidizing composition application device and a second compartment, sealingly separate from the first compartment, for receiving the activator sheet.

18. A cosmetic treatment method for whitening a body skin surface of a user comprising the following steps:
providing a kit according to claim 1 , said kit comprising an oxidizing sheet including an oxidizing composition and an activator sheet including an activator composition;
applying the oxidizing sheet on a body skin surface of the user;
placing the activator sheet on the oxidizing sheet applied on the body skin surface;
whitening the body skin surface located facing the activator sheet.

19. A process for manufacturing a kit according to claim 1 , comprising the following steps:
providing a medium intended to become an outer substrate of an activator sheet;
spreading an activator composition on the medium;
attaching the activator composition on the medium;
obtaining an activator sheet from the medium comprising the activation composition;
providing an oxidizing composition application device.

20. The process according to claim 19 , comprising a step of applying a binder prior to spreading the activator composition, the process comprising, after spreading the activator composition, drying the binder to attach the activator composition on the medium.
