  "description_excerpt": "The present invention relates in general to nail enamel compositions, and more particularly, to such compositions which are suitable for coating natural and synthetic nails. Still more particularly, the present invention relates to transparent nail enamel compositions which include small pieces of light-reflecting decorative material known as glitters.\n\nNail enamel compositions include a class of nail care products regularly used by women as part of their beauty care routine. These nail care products are available in a multitude of product formulations, from clears to infinite colors. Typically, clear nail enamel compositions include a film forming polymer, a film forming resin, a plasticizer and one or more solvents. In the case of a color nail enamel composition, the product will also include a thixotropic compound, a suspending agent and one or more pigments, or in the alternative, an organic coloring polymer may be used. In addition to these components, a number of optional and proprietary components are often included such as UV light absorbers, moisturizers, stabilizers, fragrances and the like.\n\nNail enamel compositions particularly suitable as a color coat have included a variety of pigments which provide an opaque colored film. Nail enamel films having a semi-translucent color are formed using generally organic colorants which create a tint. In order to provide the nail enamel film with a more dramatic effect, there has been known the use of small pieces of light reflecting decorative materials known as glitters.",
