Sunscreens made with nanoparticles may cause
serious bodily harm, a report from Friends
of the Earth has warned.
need to know that manufactured nanoscale
zinc and titanium oxides are not the only
choice and are not necessarily the most
effective or safest choice for sun protection,"
the report reads.
now contain nanoscale particles of titanium
dioxide or zinc oxide, roughly 100,000 times
smaller than the width of a human hair.
The only reason for using nanotechnology
is to make the sunscreens less oily and
easier to rub into the skin.
titanium dioxide and zinc oxide have long
been used in sunscreens and are considered
relatively safe, the normal rules no longer
apply to matter on the nano scale.
