You can now buy face cream with C60 "buckballs" as the active ingredient. Is that safe? Is it simply an example of nanotech being a label to be exploited in advertising, 'bamboozling' the public?

An example of such a product is Zelens Day Cream, which you can read about at the www.zelens.com site.
![]() To quote verbatim from their site, Zelens creams uniquely contain Fullerene C60, an extremely powerful anti-oxidant, for which its three discovers received the Nobel Prize for Chemistry in 1997 The Fullerene C60 in Zelens creams is 100 times more effective than the same concentration of Vitamin E in neutralising the harmful "free radicals" which cause premature aging of the skin There is an excellent short article on this whole issue at this URL: http://pubs.acs.org/cen/science/84/8413sci3.html the author quotes Robert F. Curl Jr., one of the Nobel prize winners to whom the Zelens site refers (!), as saying I would take the conservative path of avoiding using such cosmetics while withholding judgment on the actual merits or demerits of their use. |

Simon Benjamin wrote (18:58 22/11/06): Looks like the price varies from about £135 / 30ml to £95 / 15ml depending on the cream type - but the concentration of C60 is not specified. It is surprising that they can get away without specifying C60 concentration. As I understand, the regulations regarding cosmetics are much looser than those for food or pharmaceutical products, even though a large number of substances can cause harm when absorbed through the skin. |

I thought that anti-oxidants have been discredited as a health benefit recently.

I would expect many nanomaterials (e.g. TiO2 and certainly the polyaromatic systems such as C60) to be potent carcinogens.
