[Tattooing dyes].

Abstract

Nine different tattoo dyes were analysed by various tests. Mixtures of organic dyes and inorganic filler were found; the inorganic filler consisted mainly of titanium dioxide (TiO2). Heavy metals, e.g. mercury, cadmium, or chrome as the common components of the traditional tattoo dyes, are capable of evoking unwanted skin reactions, but were not detected. Tattoo dyes are not officially controlled, and thus it is not known which substances-in addition to those identified by us-are presently used to produce ornamental tattoos. However, our results suggest that classic dyes have been superceded by newer, mainly synthetic dyes.
