Abstract: Nail enamel compositions, particularly of the nitrocellulose type, have added a small amount of microcrystalline cellulose powder. When the compositions are applied to the nails, the microcrystalline cellulose particles act in lieu of long thin fibers to reinforce and strengthen the enamel coating while some of the particles tend to settle into the valleys between the nail ridges to smooth out the surface of the nails. These enamel compositions can be used without prior application of a filler coat to give a smooth, glossy, reinforced finish to the nails with no fibers visible.
