Abstract

The UV nail gel area has seen a significant growth in the cosmetics industry. The significant performance advantage over traditional nail polishes cannot be under-stated. The ability to take a liquid that has been applied to the human nail and cure it within minutes is the major driving force for the development of UV nail gels. Adhesion of the UV nail gel lacquer can be problematic unless the surface free energy and mechanical properties are taken into account. Since the UV nail gels are so highly cross-linked, the removal can also be problematic and new techniques are being developed to reduce the stress on the human nail. Longevity of the UV nail gel finish is also very important but needs to be buffered with the fact that it will be removed within two weeks. Safety of the UV cure lights, (meth) acrylate monomers and oligomers is an issue and needs to be taken into consideration during their use.
