British concerns about nanocosmetics

A consumer advocacy group in the UK has highlighted the fact that so-called "nano materials" are being used in a wide range of cosmetic products despite unresolved issues surrounding their safety. The "Which?" organization says that nano emulsions and other products used by famous brands such as L'Oreal raise few concerns, but the use of fullerenes and nanoparticles of UV filters, such as titanium dioxide and zinc oxide, have seen European Union experts asking for more evidence of safety, the organization says.
