The European Commission’s Scientific Committee for Consumer Safety has determined that a UV filter is safe at a concentration of up to 10 percent in sunscreen products. While the committee ruled in its revised opinion that 1,1’-(1,4-piperazinediyl)bis[1-[2-[4-(diethylamino)-2-hydroxybenzoyl]phenyl]- methanone (HAA 299) does not pose a risk of systemic toxicity to humans at this concentration, the ruling does not include an evaluation of HAA 299 filters composed of nanoparticles nor does it apply to inhalation exposure, due to insufficient data provided.
