Abstract

A formulation for a nail polish composition which is curable with UV light is provided. The composition can be applied in a single coating and does not include solvents such as tolualene, dibutyl phthalate, or formaldehyde. The coating once cured provides multi-coating results using only a single coating and can be covered with an optional gloss or other decorative top coating.

Claims (46)

1. A nail polish composition, comprising:

a first mixture component which is substantially 45% by weight of the total composition, consisting of one or more oligomers, from a group of oligomers consisting of: Di-HEMA Trimethylhexyl Dicarbamate, and, Methacrylic Acid2-[[[[(5-Isocyanato-1,3,3-Trimethylcyclohexyl) Methyl]Amino]Carbonyl]Oxy]Ethyl Ester;

a second mixture component, which is substantially 25.7% by weight of the total composition, consisting of one or more monomers, from a group of monomers consisting of: 2 Hydroxypropyl Methacrylate, 2 Hydroxy Ethyl Methacrylate, and Pyromellitic glycerol dimethacrylate;
