  A set of tattoo inks from a top brand was analysed by means of
Synchrotron-based X-ray Fluorescence spectrometry (Sy-XRF), Atomic Absorption
spectrometry (AAS) and Raman Spectroscopy to investigate the presence of toxic
metals and hazardous substances. Quantitative analysis shows that Cr, Cu and Pb
content is above the maximum allowed levels established by the Council of
Europe in the resolution ResAP(2008)1 on requirements and criteria for the
safety of tattoos and permanent make-up. Raman analysis reveals the presence of
pigments Blue 15, Green 7 and Violet 23 in blue, green and violet inks that
belong to a list of prohibited substances mentioned in ResAP(2008)1. Besides,
Pigment White 6, carbon black, Pigment Red 8 and a diazo yellow were also
identified in white, black, red and yellow inks. The results presented in this
study show the importance of regulating tattoo ink composition.
