For the past million generations, children grew up without much attention to hygiene. No toothpaste, no sunscreen, maybe just a bit of lard soap before a special occasion -- otherwise they just cleaned off automatically as they played inthe river. Now parents want to throw all kinds of chemicals at them. Wired has the details about one popular skin cream, including this doozy:
Rub this flower-scented lotion on your skin or stick your face in a diesel's tailpipe, where benzophenone is present in the exhaust. Either way, you get a nice sunscreen. If swallowed or inhaled, though, the substance may disrupt hormones and mess with your brain. Scientists — and probably industry lawyers — recommend against using it on kids.
