説明 | This nail was removed due to fungus, which are between the keratin of the nail. The nail had a layer of nail polish on the surface. Abuse of nail polish can cause weakening of the nail and the appearance of fungus. It has also been used to hide fungal nails. Nail polish was already used in ancient Egypt and ancient China as a social badge, with ingredients other than those used today. Modern nail polish consists predominately of a film-forming polymer dissolved in a volatile organic solvent. The most common polymer is nitrocellulose, although the more expensive cellulose acetates such as CAB are claimed to give better performance. In gel nail varnish, the polymer is usually some sort of acrylate copolymer. The solvents are commonly butyl acetate or ethyl acetate. Low levels of various additives are included to give the desired finish.Some of the ingredients in nail polish and nail polish remover are toxic, which is why some governments are banning them.Image contributed by Dr. Jerad Gardner - @JMGardnerMD |
