Heavy Metals in Cosmetic Products

Metals are present in various cosmetic products. Metals that are undesirable from a toxicological point of view are of particular   interest. They may only be present in cosmetics in technically unavoidable quantities. Reliable analysis of these metals   in the low concentration range is therefore essential. In the present study, a proficiency test was performed to determine how   comparable the analysis of heavy metals in cosmetic samples can currently be. The results show that the currently valid legal   regulations can be monitored and complied to with the current analytical technology.
