Sunscreens containing nanoparticles alarms consumer group

The consumer group CHOICE is demanding more honesty from sunscreen manufacturers after many leading brands were found to contain nanoparticles. There is controversy as to whether the particles, which are smaller than 100 billionths of a meter, can penetrate the skin and have harmful side-effects, says CHOICE. However many of these sunscreens contain nano-grade titanium dioxide and zinc oxide that enable them to offer the same sun protection but go on clear and with less skin residue.

Scientists report potential toxicity of nanoparticles in consumer products

Scientists are reporting that particle size affects the toxicity of zinc oxide, a material widely used in sunscreens. Particles smaller than 100 nanometers are slightly more toxic to colon cells than conventional zinc oxide. Solid zinc oxide was more toxic than equivalent amounts of soluble zinc, and direct particle to cell contact was required to cause cell death.
