Nanoparticles and other nanostructured materials have unique properties which cannot be achieved when working with the bulk form of material. Applications for these special properties have been suggested in many industries – the cosmetics industry is one of those most eager to make the most of the opportunities presented by nanotechnology. Nanomaterials have been used to try and improve the performance of a wide range of products, from sunscreen, moisturiser and anti-ageing creams to hair care.

Many of the main cosmetics manufacturers have at least some “nano-enhanced” products in their range. However, there is still some controversy over the safety of these novel materials, and the regulation as regarding nanomaterials in cosmetics is unclear in many parts of the world. More work is underway to better understanding the long-term impact of nanomaterials on human health. Whatever the outcome of the current controversies, it seems highly likely that nanomaterials will feature heavily in the future of the cosmetics industry.
