Special Issue Information

Dear Colleagues,

In recent years, nail care has been playing a growing role in the cosmetics market. In fact, next to enamels and products for make up, more and more formulations, with a specific effect on nail disorders, have been commercialized. Products claiming moisturizing effects for brittle and weakened nails; formulations with bleaching efficacy, with a hardener claim for the lamina; or a softening effect for the cuticles have been produced.

Although the Regulation 1223/2009 states the assessment of cosmetic safety and efficacy, until now, it has been very difficult to accomplish these legislative requests for nail products. A number of ingredients, some of them dangerous, were used in these kind of products, and only very few studies regarding their safety and efficacy have been published.

In this Special Issue, the aspects related to the evaluation of the safety and efficacy of nail care product will be discussed. I strongly believe that the matter is very important and that this Special issue will be useful to clarify the critical points related to the development of products for nails. It will also allow to disseminate the best approaches to evaluate the safety of ingredients and finished products for nail care, and to disclose the most suitable in vitro/in vivo protocols to support the claims.

Over the past several decades, the commercialization of nail cosmetics has increased. From nail polishes to artificial nails, different methods of nail beautification have become popularized. However, the impact of these products remains largely unknown. Governments have passed legislation in attempts to regulate nail cosmetics, but these regulations may not be adequate and are difficult to enforce. Knowledge of the safety and efficacy of nail products remains limited due to the relative dearth of literature published on the topic. This review serves to summarize and interpret the data available regarding common nail products and their safety and efficacy. Nail products such as nail polish, nail polish removers, and artificial nails have shown to have some adverse effects through case reports and studies. Harmful substances such as toluenesulfonamide-formaldehyde resin and methacrylates have been identified in commercial nail products, leading to several adverse effects, but in particular, allergic contact dermatitis. Exposure to substances such as acetonitrile found in removers may have more toxic and caustic effects, especially if ingested. In addition, for nail technicians there are negative effects linked with occupational exposure. Compounds used in nail products may become aerosolized and lead to asthma, eye and throat irritation, and even neurocognitive changes. Full article
