Study Finds 90% of US Tattoo Inks Mislabel Ingredients

Researchers call for stricter regulations after discovering harmful substances in tattoo inks.

A comprehensive study reveals that 90% of tattoo inks in the US contain unlisted or mislabeled ingredients, raising health concerns.
Researchers from Binghamton University found substances such as polyethylene glycol and propylene glycol, which can cause organ damage and allergic reactions, respectively.
The study, published in Analytical Chemistry, highlights the need for stricter manufacturing regulations and better labeling practices for tattoo inks.
Only one brand out of nine tested had accurately listed ingredients on its labels, underscoring widespread discrepancies.
The FDA has recently begun to regulate tattoo inks, a move that could lead to improved safety and labeling practices.
