Novel synthesized filter absorbs radiation in ultraviolet region with high absorption capability, so it can be used in sunscreens. Novel synthesized organic filters PABA methyl ester and PABA methyl stearate can absorb UV light and after absorbing UV radiations, these compounds emitted their energy as IR radiations and therefore stop UV light to reach deeper into the skin.

Trace metals and other compounds in many sunscreens have unknown effects on marine ecology, say researchers studying Mediterranean waters.
