More nano-sunscreen claims revealed
"Yesterday the ABC revealed that at least 10 Australian sunscreen brands that claim to be free of nano-materials have unwittingly been using nanoparticles in their products.
Neither the safety nor the risks of nano-materials in sunscreens is scientifically proven."
Nanoparticles and sunscreen
Nanotechnology has been used in sunscreens for many years. To date, our assessment, drawing on the best available evidence, is that nanoparticulates used in sunscreens do not pose a risk. However, we continue to monitor research and welcome any new research that sheds more light on this topic.
Sunscreen formulas and their components are regulated through the Therapeutic Goods Administration (TGA). In early 2009, the TGA conducted an updated review of the scientific literature in relation to the use of nanoparticulate zinc oxide and titanium dioxide in sunscreens.
The TGA review concluded that:
