Abstract
BACKGROUND: Henna has a very low allergic potential, and severe allergenic contact dermatitis is mainly caused by p-phenylenediamine (PPD), which is added to temporary black 'henna tattoos', and potentially also by some heavy metals. OBJECTIVE: To determine the presence of, and quantify, Lawsone, PPD and heavy metal contaminants (cobalt, nickel, lead, and chromium) in commercial temporary black henna tattoo mixtures (n = 25) sold in Turkey. METHODS: Lawsone and PPD concentrations were analysed with high-performance liquid chromatography, and heavy metal quantification was performed with inductively coupled plasma mass spectrometry. RESULTS: PPD was found in all 25 black henna tattoo samples purchased from tattoo shops; levels varied between 3.37% and 51.6%. Lawsone was detected (0.002-88.2%) in 21 of the 25 temporary black henna tattoo samples analysed. Heavy metal contaminant levels were 0.44-3.11 ppm for Co, 1.13-2.20 ppm for Ni, 1.59-17.7 ppm for Pb, and 35.0-76.9 ppm for Cr. CONCLUSIONS: Our results suggest that commercial temporary black henna mixtures containing PPD levels up to 51.6% pose a risk of contact sensitization and severe allergic contact dermatitis among users. It is important to identify both the additives and metallic contaminants of black henna tattoo products; the significance of metal contaminants has still to be assessed.
