applying a nail enamel to the mammalian nails wherein the nail enamel comprises one or more of nanoclay, nanosilica, nanopigments or nanoceramic particles.
2 . A method for making a mammalian nail enamel effective for increasing strength and flexibility of mammalian nails, comprising:
adding nanoparticles of one or more of nanoclay, nanosilica, nanopigments or nanoceramic particles to a nail enamel formulation.
3 . The method for making a mammalian nail enamel of claim 2 wherein the nanoparticles are added in a concentration range of about 0.05% to about 1% of the nail enamel by weight.
4 . The method of claim 2 wherein clay or silica or ceramic particles larger than nanoparticles are also added to the nail enamel formulation.
5 . The method of claim 2 , wherein the nanoparticles are coated with an ammonium-based material such as dimethyl, dehydrogenated tallow, quaternary ammonium salt.
6 . The method of claim 2 , wherein the nanoparticles comprise particles having a 1- to 2-layer clay mineral with a plate-like structure, the platelet having a thickness of about one Angstrom and surface dimensions within a range of about 70 to more than 150 nanometers.
7 . The method of claim 4 wherein the nanoparticles are added in a concentration of about 0.5% by weight of the nail enamel and the larger silica or clay or ceramic particles are added in a concentration of about 0.5% by weight.
8 . The method of claim 2 , wherein the addition of the nanoparticles improves toughness of the mammalian nails, when applied to the nails.
9 . The method of claim 2 , wherein the addition of the nanoparticles increases impact resistance of the mammalian nails, when applied to the nails.
10 . The method of claim 2 , wherein the addition of the nanoparticles increases mar resistance of the mammalian nails, when applied to the nails.
