Unlabeled and with very little health and environmental safety testing, nanoparticles pose risks to our health and our environment.

Friends of the Earth recently released a consumer guide about the potential dangers of nanoparticles in sunscreens, but such particles are actually used in all sorts of cosmetics, including some sold by the biggest names in cosmetics like L'Oreal, Johnson & Johnson, and Revlon.

Please tell the Food and Drug Administration to take regulatory responsibility for this emerging technology's use in consumer products.
