Nail gel builder composition
A UV curable gel composition adapted to be applied to a nail with a brush to build and extend the nail comprising one or more acrylate/carbamate copolymer resins, one or more urethane methacrylate oligomers of di-functionality, one or more methacrylate resins, one or more Isophorone Diisocyanate end-capped with Hydroxyethyl Methacrylate resins, one or more ethylenically unsaturated mono functional monomers, a photoinitiator and at least one acid-based adhesion promotor wherein the composition having a viscosity of about 11,000 centipoise to about 14,000 centipoise and a specific gravity of less than about 1.2. The invention includes an applicator kit for the composition and methods of its use.
1. A UV curable gel composition adapted to be applied by brush onto a nail to build and extend the nail, comprising:
one or more acrylate/carbamate copolymer resins;
one or more urethane methacrylate oligomers of di-functionality;
one or more methacrylate resins;
one or more Isophorone Diisocyanate end-capped with Hydroxyethyl Methacrylate groups;
one or more ethylenically unsaturated mono functional monomers;
at least one photoinitiator; and
at least one acid-based adhesion promotor wherein the composition has a viscosity of about 11,000 centipoise to about 14,000 centipoise.
2. The composition of claim 1 wherein the composition has a specific gravity from about 1.02 to about 1.12.
3. The composition of claim 1 wherein the one or more acrylate/carbamate copolymer resins comprise about 30 wt. % to about 40 wt. % of the total weight of the composition, the one or more urethane methacrylate oligomers of di-functionality comprise about 15 wt. % to about 20 wt. % of the total weight of the composition, the one or more methacrylate resins comprise about 5 wt. % to about 10 wt. % of the total weight of the composition, the one or more Isophorone Diisocyanate end-capped with Hydroxyethyl Methacrylate groups comprise about 5 wt. % to about 10 wt. % of the total weight of the composition and the one or more ethylenically unsaturated mono functional monomers comprise about 20 wt. % to about 30 wt. % of the total weight of the composition.
4. The composition of claim 1 further including at least one of sucrose benzoate, vitamins, and violet dye.
5. A kit for containing and applying the UV curable gel composition for building and extending a nail of claim 1 , the kit comprising a bottle adapted to block the contents therein from exposure to UV light and a bottle cap, the cap having an applicator brush for applying the UV curable gel composition to a nail.
6. A method for building and extending a nail comprising the steps of:
a) applying the composition of claim 1 onto a nail with a brush; and
b) exposing the applied composition to UV light to cure the applied composition.
