FDA seeks clearer labels on sunscreen

The Food and Drug Administration on Thursday proposed new labels for sunscreens that would eliminate misleading claims such as ''sunblock'' and ''waterproof'' and create a new system for rating products' effectiveness against damaging ultraviolet rays.

The new rules, which must go through a 90-day public comment period, are meant to get sunscreen makers to replace what the FDA has called ''unsupported, absolute'' claims with less definitive language such as ''water resistant'' or ``very water resistant.''
