Cosmetics may contain harmful particles
Researchers at the Project on Emerging Nanotechnologies in
Washington say tiny particles used in cosmetics and sunscreens may pose
Speaking at the Science Media Center in London, Andrew Maynard, of
the Project on Emerging Nanotechnologies, said: 'In a sense we are
using humans as guinea pigs with a lot of these products. There are few
proven risks but there are proven hazards.'
Such particles exist in the air, produced by volcanoes and the
burning of fossil fuels, but scientists can now engineer materials at
tiny sizes to give them useful properties, the Telegraph reported.
Researchers set up an Internet directory listing more than 200
products that claim to use nanotechnology. Face creams using
nanoparticles include L`Oreal`s Revita-Lift treatment mask and Lancome
Renergie Morpholift. Some Soltan sun creams, produced by Boots and
Oxonica, also make use of nanotechnology.
A Royal Society and Royal Academy of Engineering study concluded
that most nanotechnologies posed no risks but highlighted potential
hazards and called for tighter controls.
