According to a new study from Duke University and the Environmental Working Group (EWG), painting your nails could potentially release an endocrine-disrupting chemical into the body.
The study shows that women who painted their nails with products that contained triphenyl phosphate (TPHP) had a metabolite of the chemical in their bodies about 10 to 14 hours after applying the polish. The body's levels of diphenyl phosphate (DPHP) then increased sevenfold, Fox News reports.
Previous studies have reportedly found that TPHP exposure can lead to endocrine corruption and can cause reproductive and developmental problems in animals. TPHP has also been linked to weight gain and obesity in a recent study.
“It is very troubling that nail polish being marketed to women and teenage girls contains a suspected endocrine disrupter,” Johanna Congleton, a senior scientist at EWG, and the co-author of the study, said in a news release, according to Fox News.
“It is even more troubling to learn that their bodies absorb this chemical relatively quickly after they apply a coat of polish," she added.
Researchers used 10 types of polishes for the study and discovered the chemical in eight of them.
More than 1,500 nail products, like those produced by Sally Hansen and OPI, contain TPHP, according to EWG's Skin Deep cosmetics database.
