Tattoo inks may contain toxic heavy metals, new study shows; products not regulated by FDA
by Mike Adams, the Health Ranger, NaturalNews Editor
A new study by some Arizona researchers may bring light to an overlooked issue regarding tattoo parlors. The study says inks used in tattoo inks contain toxic heavy metals like copper and nickel. While it's still unclear how much of the metals the inks contain, or whether there is any health risk, the findings have prompted some to ask whether the inks are subject to FDA approval. Surprisingly, they are not.
Dirty needles may be the chief health concern with tattoos, but preliminary research suggests the inks used to make the body art may harbor potentially toxic heavy metals.
In an analysis of 17 tattoo inks from five manufacturers, researchers found evidence of a number of different metals, such as nickel and copper, in the products.
It's unclear how much metal may be in the different inks - or whether there is any health risk.
Still, the study authors say the findings highlight the lack of oversight of tattoo ink manufacturing.
The U.S. Food and Drug Administration (FDA), which approves the color additives used in foods, cosmetics and drugs, does not regulate the inks used for tattooing, and no color additive has ever been approved for injection into the skin.
"A lot of people are surprised by that," said Leslie Wagner, a chemistry student at Northern Arizona University in Flagstaff and a co-author on the new study.
Many tattoo enthusiasts may assume that an ink that's injected into the skin has been approved by regulators to meet certain standards, she noted in an interview with Reuters Health.
However, it is not even clear what goes into a given tattoo pigment.
Because the inks are not sold directly to consumers, manufacturers are not required to list the components on the product label, according to the FDA.
And no previous scientific studies have attempted to describe the composition of the inks, Wagner said.
In their research, Wagner and co-author Haley Finley-Jones have so far found that tattoo ink compositions vary from manufacturer to manufacturer, and from color to color.
She and Finley-Jones presented the preliminary findings Sunday in San Diego, at the 229th national meeting of the American Chemical Society.
