Abstract

The present invention relates to a photocrosslinkable cosmetic composition, comprising in a physiologically acceptable medium: —at least one photocrosslinkable urethane (meth)acrylate compound P1 comprising at least one structural unit: (I) —at least one photocrosslinkable urethane (meth)acrylate compound P2 comprising at least one polyether chain, said compound having a molar mass greater than or equal to 1000 g/mol, —at least one film-forming polymer P3, —at least one photoinitiator, and —at least one volatile solvent chosen from acetone, ethyl acetate, and propyl acetate, said solvent being present in said composition at a content greater than or equal to 20%, preferably greater than or equal to 30%, by weight in relation to the total weight of said composition, wherein the ratio of the total mass of P1 and P2 to the total mass of P3 is less than or equal to 4.0.

First claim

The invention claimed is:

1. A photocrosslinkable cosmetic composition . . . wherein the ratio of the total mass of P1 and P2 to the total mass of P3 is between 0.5 and 2.0.

2. The composition according to claim 1 , further comprising a coloring agent chosen from the group consisting of soluble dyes, pigments, nacres and glitter.

3. The composition according to claim 1 , wherein said composition further comprises a (meth)acrylate monomer, wherein the proportion of the (meth)acrylate monomer is less than or equal to 10% by weight in relation to the total weight of said composition.

4. The composition according to claim 1 , comprising from 10% to 15% by weight of said at least one photocrosslinkable urethane (meth)acrylate compound P1 in relation to the total weight of said composition.

5. The composition according to claim 1 , comprising from 5% to 10% by weight of said at least one photocrosslinkable urethane dimethacrylate compound P2 comprising a poly(ethyleneglycol) chain in relation to the total weight of said composition.

6. A kit comprising:
the photocrosslinkable cosmetic composition according to claim 1 ,
an abrasive material having a granulometry greater than or equal to 200 pm, and
a LED lamp or an UV lamp.

7. A makeup and/or care method of a nail and/or false nail, comprising the following steps:
a) applying, onto a nail or a false nail, the photocrosslinkable cosmetic composition according to claim 1 , whereby a coat consisting of at least one layer of said photocrosslinkable cosmetic composition is deposited, and
b) exposing the coated nail or false nail obtained following step a) to UV or visible light radiation, whereby the photocrosslinking of the photocrosslinkable compounds PI and P2 of said composition is carried out.

8. A makeup and/or care method of a nail and/or false nail, comprising the following steps:
i) rubbing the surface of a nail or false nail with an abrasive material having a granulometry greater than or equal to 200 pm,
ii) applying the photocrosslinkable cosmetic composition according to claim 1 onto the surface of the nail or false nail which has been rubbed following step i), whereby a coat consisting of at least one layer of said photocrosslinkable cosmetic composition is deposited, and
iii) exposing the coated nail or false nail obtained following step ii) to a LED lamp or an UV lamp, whereby the photocrosslinking of the photocrosslinkable cosmetic composition is carried out.
