Mercury & Mercury CompoundsUpdated a month ago

(Additional Names: Thimerosal)

Mercury and Mercury Compounds are used as a preservative in vaccines and cosmetics. According to the Federal Food and Drug Administration (“FDA”), mercury compounds are readily absorbed through the skin and accumulate in the body, increasing risks of various adverse health effects including the disruption of the nervous system. They may also cause allergic reactions and skin irritation. Mercury is considered particularly toxic to the developing brain during pregnancy, infancy and childhood. The FDA has banned the use of mercury compounds in all cosmetics except those used around the eyes, where levels are limited to 65 parts per million (ppm).
