Nano Nontoxic

Sunscreens Containing Nano-Sized Titanium Dioxide Particles Appear To Be Nontoxic, Effective.

MedWire (5/13, Albert) reported that, according to a study published in the June issue of the International Journal of Cosmetic Science, "recently developed sunscreens containing nano-sized titanium dioxide (TiO2) particles are likely to have better efficacy than older creams containing micron-sized TiO2 particles, with no increase in toxicity." Researchers from the Food and Drug Administration came to this conclusion after evaluating "the effects of the two types of TiO2 particles in sunscreen in terms of ultraviolet (UV) light attenuation, product stability, and possible skin barrier damage." Specifically, "they tested uncoated TiO2 with a primary particle size of 21 nm (nanoscale), coated TiO2 with a primary particle size of 50 nm (nanoscale), and submicron, coated TiO2 with a primary particle size of 250 nm (microscale)."
