Researchers found that 83% of tattoo inks contain hidden ingredients that are not listed.
Tattooing is an art that people have been practicing for thousands of years. Statistics show that one-third of US adults have at least one tattoo on their body. But according to Science Alert, researchers have now discovered something scary in the inks that tattooists use to create tattoos.
In a new study, a team led by a chemistry researcher at Binghamton University in New York analyzed more than fifty tattoo inks from nine popular brands used by tattoo artists. The study authors note that their work was inspired by ink used in previous studies that contained substances not listed on labels.

Scientists tested ink produced by both small and large companies and found that 45 of 54 samples contained substances not listed on the label. For example, various pigments or additives not included in the list. Some labels also contained additives that were not found in trace amounts in the inks: 36 packs contained glycerin, but it was found in only 29 inks.
The results of the study show that 15 inks contained the allergen propylene glycol, while others contained harmful or just plain weird ingredients, such as antibiotics. The study authors note that it is still unclear whether this contamination is accidental or intentional, and additional research will be needed to answer this question.
Previous studies have shown that tattoo ink affects immune cells and, according to scientists, small amounts of this ink can even leak into lymph nodes; This is quite worrying.
Note that in 2021, scientists discovered some problems with mislabeling and unspecified additives in 90% of products. Additionally, metal impurities were found in the pigment in concentrations exceeding established limits.
Tattoo ink, especially shades of red, can cause allergic reactions such as swelling, itching, and blistering months or even years after the initial injection. But if ingredients aren’t listed on food labels, it can be difficult to figure out what caused the reaction and prevent it from happening again.
Ultimately, the study authors hope their findings will help improve the quality of tattoo inks produced.
