Abstract

The present invention relates to compositions, kits, and films formed therefrom which are useful as cosmetic or therapeutic agents, as well as methods of their use. The compositions, kits, and films herein are particularly useful as polishes for mammalian nails. More particularly, the present invention relates to compositions and kits which, when applied to mammalian nails form films exhibiting long wear. When applied to mammalian nails, the present kits and compositions form films exhibiting surface energies from about 32 mN/m to about 43 mN/m and polarities from about 0.19 to about 0.29. The present invention further relates to methods of coating mammalian nails with films exhibiting surface energies from about 32 mN/m to about 43 mN/m and polarities from about 0.19 to about 0.29.
