14. Cosmetic Applications

Nanocosmetics represent a fast growing segment within the cosmetic industry. They are cosmetic products with nano-based structures included either as nano-inclusions or as delivery vehicles. Nanocosmetics exhibit enhanced properties compared to traditional cosmetics including improved skin hydration, improved skin penetration, enhanced stability and bioavailability. Major cosmetic companies like L’Oréal, Christian Dior and Estee Lauder are investing in nanocosmetic research as well as nano-patents. Different nanocosmetics have already made their way to the market in the form of sunscreens, makeup, lotions and shampoos. Enhanced properties of the nano-based products and keeping up with the nano-trend are among the main drivers behind the increase in nano-based cosmetics. Yet the safety of the nanocosmetics is one of the main barriers against its wide application. One of the main enablers, however, that allowed the introduction of large number of nanocosmetics till now is the absence of specific regulatory rules concerning nano-based cosmetics.
