Abstract

A method of preparing colored UV-curable artificial nail gel compositions comprising dispersing a pigment in an organic liquid to form a pigment concentrate and mixing the pigment concentrate with a polyfunctional acrylic monomer and/or a polyfunctional acrylic oligomer, and the resultant highly colored artificial nail gel are disclosed.

Claims

1. A method of preparing colored UV-curable compositions useful for adornment of natural and artificial nails and artificial nail extensions comprising dispersing a pigment in an organic liquid to form a pigment concentrate, the organic liquid comprised of one or more organic chemicals selected from solvents, ethylenically unsaturated monomers, and ethylenically unsaturated oligomers;

and mixing the dispersed pigment concentrate with a radiation-curable nail gel composition comprising one or more ethylenically unsaturated monomers, one or more ethylenically unsaturated oligomers, or mixtures thereof, and a photoinitiator.

2. The method of claim 1 wherein organic liquid is a non-reactive solvent.

3. The method of claim 1 wherein organic liquid comprises one or more non-reactive solvents selected from butyl acetate, ethyl acetate, isopropanol, xylene, toluene, acetone, and methyl ethyl ketone.

4. The method of claim 1 wherein organic liquid comprises one or more chemicals selected from mono-, di-, tri-, and tetra-functional ethylenically unsaturated monomers and oligomers.

5. The method of claim 1 wherein organic liquid comprises one or more chemicals selected from (meth)acrylic monomers and oligomers.

6. The method of claim 1 wherein the gel composition comprises a mono-, di-, tri-, or tetra-functional acrylic or methacrylic monomer.

7. The method of claim 1 wherein the gel composition comprises a polyfunctional polyurethane (meth)acrylate oligomer.

8. The method of claim 1 wherein the gel composition comprises monomer selected from hydroxyethyl (meth)acrylate, hydroxypropyl (meth)acrylate, trimethylolpropane tri (meth)acrylate, and isobornyl (meth)acrylate.

9. The method of claim 1 wherein the gel composition comprises aliphatic polyester based urethane diacrylate oligomer.

10. The method of claim 1 wherein the pigment is selected from the group consisting of pigments listed on the FDA color additives web site or Annex IV of the Cosmetic Directive 76/768/EEC, Coloring Agents Permitted in Cosmetics.

11. The method of claim 1 wherein the artificial nail gel comprising the pigment concentrate has a viscosity of below 25 poise.

12. The method of claim 1 wherein a photoinitiator is added to the polyfunctional acrylic monomer or oligomer before blending with the pigment concentrate.

13. The method of claim 1 wherein a gel comprising the polyfunctional acrylic monomer and/or oligomer are sold separately from the pigment concentrate.

14. A method of adorning natural or artificial nails comprising applying a composition prepared by the method of claim 1 to a fingernail or toenail followed by curing under UV light.

15. The method of claim 1 wherein the ratio by weight of pigment concentrate to radiation-curable nail gel composition is preferably equal to or less than 1:

2.

16. An artificial nail gel composition prepared by the process of claim 1.

17. An artificial nail prepared by curing under actinic radiation a composition of claim 16.
