The art of tattooing has been around for centuries, with a significant 32 percent of adults in the United States having at least one tattoo. However, a recent study conducted by chemistry researcher Kelli Moseman and her team at Binghamton University revealed some alarming findings. After analyzing over 50 tattoo inks from nine different brands in the US, they discovered that 45 of the 54 inks contained substances that were not listed on the label. These unlisted ingredients ranged from unlisted pigments to additives, including potentially harmful substances like antibiotics.
Concerns Over Mislabeling and Unlisted Additives
The study also highlighted major issues with mislabeling and unlisted additives in tattoo inks used in the European Union, with around 90 percent of products showing similar problems. The presence of metal impurities at concentrations exceeding regulated limits was another troubling discovery. This raises concerns about the safety of tattoo inks and the potential risks they pose to individuals who receive tattoos.
The findings of these studies underscore the importance of improved labeling and manufacturing practices within the tattoo industry. John Swierk, a chemist at Binghamton University and senior author of the study, emphasized the need for manufacturers to reevaluate their processes. Additionally, artists and clients are encouraged to advocate for better labeling practices to ensure transparency and safety in tattoo inks.
The presence of unlisted ingredients in tattoo inks poses significant health risks to individuals. Allergic reactions, such as swelling, itching, and blisters, can occur months or even years after getting a tattoo, especially with red-colored inks. Without proper labeling, identifying the cause of these reactions becomes challenging, making it difficult to prevent future incidents.
Advanced Analytical Techniques Used in the Study
Moseman and her colleagues utilized advanced analytical techniques to identify unlisted substances in tattoo inks. Raman and XRF spectroscopy were used to detect pigments, while NMR spectroscopy and mass spectrometry were employed to identify carrier solutions. The researchers focused on substances present in the carrier solution at concentrations of 2,000 parts per million or more, potentially missing components present at lower concentrations.
In response to these findings, regulatory bodies like the European Chemicals Agency and the US Food & Drug Administration have taken steps to address the issue of unlisted ingredients in tattoo inks. The FDA now regulates tattoo inks as part of its oversight of cosmetics, allowing for recalls of products and improved labeling requirements. While these regulations are relatively new, they serve as a crucial foundation for future studies to monitor and enhance the safety of tattoo inks.
The presence of unlisted ingredients in tattoo inks highlights the need for greater transparency and regulation within the tattoo industry. By addressing labeling issues and ensuring the safety of tattoo inks, manufacturers, artists, and clients can work together to promote the health and well-being of individuals seeking tattoos.
