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.

Nail enamel containing microcrystalline cellulose

Hair removal compositions useful for cosmetic, medical and other purposes comprise 90 to 99.5% corn syrup and 0.5% to 10% added water by weight. The compositions can also include additives such as germicides, preservatives and opacifiers. The compositions are used by applying them to the surface of the skin in a hairy area, pressing a sheet of paper or other fibrous material against the area and subsequently lifting the sheet of fibrous material or peeling it off the skin surface. The compositions are also useful in removing blemishes and scaly, flaky or dry skin.

Depilatory compositions and methods

Ointment compositions for the treatment of styes and related infectious conditions of the eyelid. The ointments contain an emollient base, including white petrolatum, mineral oil and microcrystalline wax, as well as boric acid, wheat germ oil and mercuric oxide, the concentration of boric acid in the ointment is about 2-10% by weight, as is the concentration of the wheat germ oil, while the mercuric oxide is present in a concentration of about 1-1.2% by weight. The wheat germ oil enhances the anti-bacterial potency of the mercuric oxide, and the boric acid stabilizes the mercuric oxide in the presence of the wheat germ oil to prevent discoloration of the ointment.
