Berlin, Germany – A recent study conducted by Swierk et al. has shed light on the concerning lack of accuracy in labeling commonly used tattoo inks in the United States. By utilizing advanced methods such as Raman spectroscopy, nuclear magnetic resonance spectroscopy, and electron microscopy, the research team was able to identify specific pigments and ingredients in various tattoo inks.
The study revealed that a staggering 90 percent of the tested inks in the United States exhibited major labeling discrepancies. Of particular concern were allergic reactions associated with certain pigments, notably red inks, as well as the presence of unlisted ingredients with potential adverse effects. In fact, more than half of the tested inks contained unlisted polyethylene glycol, a substance that could lead to organ damage with repeated exposure.
In response to the growing concerns over harmful chemicals in tattoo ink, the European Commission has recently taken action by banning two widely used blue and green pigments – Pigment Blue 15 and Pigment Green 7. The Commission cited low purity and the presence of hazardous substances in these pigments as the basis for their decision. In contrast to the EU’s strict regulations, the United States has been criticized for its less stringent oversight of tattoo ink ingredients.
Swierk’s team expanded their analysis to include tattoo inks from European suppliers, finding that a majority of the tested inks did not comply with EU regulations. The researchers highlighted the need for manufacturers to adopt better standards and emphasized the importance of enforcing existing regulations. Despite efforts to regulate tattoo ink ingredients, the study revealed challenges in enforcing bans on specific substances, such as Pigment Blue 15, due to difficulties in accurately identifying different forms of the pigment.
The findings underscore the urgent need for improved manufacturing standards and stricter enforcement of regulations in the tattoo industry. Swierk emphasized the necessity for both manufacturers and regulatory bodies to address the issue of inaccurate labeling and adhere to established guidelines to ensure the safety of tattoo consumers. The study’s implications extend beyond chemical analysis, prompting a reevaluation of regulatory approaches to guarantee the integrity and safety of tattoo inks in the global market.
