Analysis of mercury content in cosmetic products available on the Polish market

PURPOSE: Mercury is a highly toxic element and dangerous to human health and even life. Constant exposure to mercury is associated with a high risk of many health conditions. Cosmetic products, which come into direct contact with human skin, should be especially monitored for the presence of heavy metals harmful to health. Despite legal regulations regarding the content of mercury in both color and care cosmetics, this element is still present in many products. The aim of this study was to analyze selected cosmetic products to determine the presence and concentration of mercury. MATERIALS AND METHODS: The mercury content was measured in finished cosmetics products readily available in the Polish market: care creams and serum as well as color make-up cosmetics (eyeliner, eye shadow, blush). The analyses were performed using the atomic absorption spectrometry method with the AMA 254 mercury analyzer. RESULTS: Based on the conducted research, it was found that all analyzed cosmetic products contain mercury. Among the tested cosmetics, the highest mercury content was detected in care cosmetic serum that improve skin tone. CONCLUSION: Although the detected mercury content in the tested cosmetics did not exceed the permissible standards, considering the adverse impact of mercury on human health, its presence in all tested products is disturbing. Despite the low levels, mercury is still considered dangerous, especially during long-term exposure, and should be forbidden in cosmetic products.
