Abstract— A methodology based on inductively coupled plasma atomic emission spectroscopy (ICP-AES) after microwave assisted acid digestion has been developed and validated to determine the trace element content of traditional Moroccan cosmetic products like henna and takaout purchased in local markets of Morocco. Limit of detection values equal or lower than few µg g-1 were obtained for all elements under study. To assure the accuracy of the whole procedure, recovery studies were carried out on traditional cosmetic samples spiked at different concentration levels from 40 to 1600 µg L-1. Quantitative average recovery values were obtained for all elements evaluated, demonstrating the suitability of this methodology for the determination of trace elements in these samples. Accurate results were found also for a certified reference material NIST 1573a. Results obtained for henna samples were compared with those found by the Danish Environmental Protection Agency for products available in the Danish market.
