This ink is a light green ink manufactured by StarBrite colors. Preliminary analysis of the tattoo ink shows that it is comprised of a solid component and at least one molecular component. Possible concerns are related to the particle size and the possible presence of a compound containing an azo functional group. A previous analysis by Forte et al. also found the presence of  mercury, cadmium, and lead as well as high levels of manganese. The level of chromium in that study also exceeded the 1 ppm level recommended to avoid allergic reactions in people with chromium allergies.
