The FDA conducted two surveys to find lead and other chemical ingredients in cosmetics. They have a wide selection of cosmetics at different prices. The first survey was completed in March 2012 with more than 150 products, including eyeshadow, blush, lipstick, lotion, mascara, foundation, powder, compact powder, shaving cream and paint face.
FDA has contracted with Frontier Global Sciences, Inc. in Seattle, Washington to perform the analysis for this survey. Contractor uses the full dissolution method and uses FDA-approved hydrofluoric acid.
The objective of the second survey completed in February 2013 was to deepen the findings of the first survey. This time around, the researchers focused on eyeshadow, blush, powder, and lipstick. These are products containing small amounts of "heavy metals" found in the first survey.
The results show that the amount of lead in this cosmetic is very small and usually does not pose a health hazard. The FDA-approved method used in the first survey consistently gives values ​​equal to or higher than those obtained with the method used in the second survey. Both surveys found that products such as eyeshadow, blush, and pressed powder contained more heavy metals than other cosmetics. This suggests that most of these substances in cosmetics come from minerals used as colorants and fillers such as clay and talc.
