The products in this group consist of clothing, cosmetics and sunscreens. Silver is the most commonly used material, followed by carbon in the forms of either nanotubes or fullerenes, and silica, respectively. It is reported that the number of the 'Nanotech' products significantly increased about 124% within the past 14 months.
