Abstract: (1353 Views)
In the present research work, the Laser-induced breakdown spectroscopy (LIBS) technique is applied to explore the concentration of toxic elements being in tattoo inks. The elemental analysis of chromium (Cr), manganese (Mn), titanium (Ti), cobalt (Co), and lead (Pb) are selected as elements in cosmetic products. Three different colors of tattoo inks are selected. The observed spectral lines of all elements are used to calculate their concentration in all samples through the internal standard method. The calculated concentrations are then compared to permissible limits set by the Food and Drug Administration with regard to the cosmetics industry. Moreover, the discriminant function analysis (DFA) statistically reveals the differences between tattoo inks from various aspects.
