Abstract

The present invention relates to a method of applying makeup to keratinous substances, in particular the skin, the lips, the nails, or hair, the method comprising the following steps:
depositing at least one cosmetic composition on the surface to be made up, the cosmetic composition comprising:
bodies that present non-zero magnetic susceptibility and that are movable under the effect of a magnetic field; and at least one interferential pigment; and
exposing at least part of the composition to a magnetic field, so as to modify the orientation and/or displace at least some of the magnetic bodies.

First claim

The invention claimed is:

1. A method of applying nail varnish to nails, comprising:
manually depositing, using a non-magnetic cosmetic applicator, at least nail varnish on a surface of a human nail, the nail varnish comprising:
magnetic bodies that are movable under the effect of a magnetic field; and
at least one interferential pigment; and

after the depositing, manually exposing at least part of nail varnish to a magnetic device producing a magnetic field, the magnetic device located above the nail varnish during the exposing, so as to modify the orientation and/or displace at least some of the magnetic bodies resulting in formation of a visible pattern on the nail varnish according to the magnetic field of the magnetic device, the magnetic bodies within the pattern being oriented and/or displaced differently than the magnetic bodies outside of the pattern.

2. The method according to claim 1 , in which the magnetic field is exerted by a permanent magnet.

3. The method according to claim 1 , in which the magnetic field is exerted by an electromagnet.

4. The method according to claim 2 , in which the magnet or electromagnet is rotated.

5. The method according to claim 3 , in which the electromagnet is powered by at least one battery.

6. The method according to claim 3 , in which the electromagnet is switched on intermittently while the pattern is being formed.

7. The method according to claim 1 , in which the magnetic field is applied until the nail varnish obtains a fixed appearance.

8. The method according to claim 1 , in which the magnetic field is applied for a period of time that is shorter than the period of time that causes all of the magnetic bodies in the exposed region to be permanently displaced and/or oriented.

9. The method according to claim 1 , in which the magnetic field is exerted successively on different regions of the surface that are coated with the nail varnish.

10. The method according to claim 9 , wherein the magnetic field is exerted successively on regions of the surface that are disjoint.

11. The method according to claim 1 , in which at least one region of the surface that is coated with the nail varnish is not exposed to the magnetic field.

12. The method according to claim 1 , in which the applicator comprises a brush, a flocked endpiece, or a foam.

13. The method according to claim 1 , wherein the magnetic bodies particles are made up, at least in part, of the interferential pigment.

14. The method according to claim 1 , in which the magnetic bodies are different from the particles of the interferential pigment.

15. The method according to claim 1 , wherein the magnetic bodies comprise fibers or particle chains.

16. The method according to claim 1 , in which the interferential pigment is a goniochromatic pigment.

17. The method according to claim 1 , in which the interferential pigment comprises reflective particles.

18. The method according to claim 1 , in which the nail varnish includes at least one volatile solvent.

19. The method according to claim 1 , in which the nail varnish includes at least one film-forming polymer.

20. A method of applying makeup to a nail, comprising:
manually depositing, using a non-magnetic cosmetic applicator at least one cosmetic composition on a surface of the nail, the cosmetic composition comprising:
magnetic bodies that are movable under the effect of a magnetic field;
and at least one interferential pigment;
and after the depositing, manually engaging a portion of a magnetic device with a portion of the nail such that neither a magnet of the magnetic device nor the engaged portion of the magnetic device contacts the surface or the composition;
exposing at least part of the composition to a magnetic field of the magnet, the magnetic device located above the cosmetic composition during the exposing, so as to modify the orientation and/or displace at least some of the magnetic bodies resulting in formation of at least one visible pattern on the composition according to the magnetic field of the magnetic device, the magnetic bodies within the pattern being oriented and/or displaced differently than the magnetic bodies outside of the pattern.

21. The method of claim 20 , wherein the portion of the magnetic device is a positioning member.

22. The method of claim 21 , wherein the positioning member is an abutment surface.

23. The method of claim 1 , wherein the pattern is recognizable as at least one of a star, a sphere in relief, and stripes.

24. The method of claim 20 , wherein the pattern is recognizable as at least one of a star, a sphere in relief, and stripes.

25. The method of claim 1 , wherein the pattern is a repeated pattern.

26. The method of claim 20 , wherein the pattern is a repeated pattern.
