More and more demanding consumers have made cosmetic companies invest in products and research aiming at improve product quality and enhance consumer health and sustainability. Some metals are essential for the good development of beings, but there are others that are harmful to health. Of all metals only 30 are toxic, and lead, cadmium and chromium belong to this group. These metals are present in the pigments used in the manufacture of lipsticks. The legislation establishes safety limits for the presence of these metals in cosmetics, since the risk of contamination is linked to their concentration and exposure. For this reason the analysis of potentially toxic metals in lipsticks is necessary, quantifying and comparing to the contents presented not only by the companies, but also by the current legislation. Thus, this study aimed to quantify the levels of lead, cadmium and chromium in lipsticks of different brands, using acid digestion method and determination by atomic absorption spectrometry. From the results, it was possible to observe the presence of high levels of cadmium in all the analyzed brands and the highest concentrations were found in the darker shades.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
