You might want to postpone your next manicure.
Researchers from Duke University and the Environmental Working Group, discovered that nail polishes containing the ingredient Triphenyl phosphate (TPHP could be linked to weight gain).
TPHP is found in 49 percent of more than 3,000 nail polishes and treatments, according to researchers.
Nail polish brands began using TPHP to replace phthalates, a chemical that’s linked to reproductive issues, but now studies are saying that ingredient isn't any better.
The study, published in Environment International, tested urine samples of 26 participants before and after painting their nails with a polish that had 1 percent of TPHP. Within two to six hours, 24 participants had slightly high levels of diphenyl phosphate (DPHP), a chemical that signals that the TPHP has been processed in the body. Within 10 to 14 hours, every participant’s DPHP levels were seven times higher!
So why is that bad? TPHP is an endocrine disruptor, meaning that it can interfere with your hormones, potentially leading to weight gain. Previous studies also showed that women process TPHP more than men, leading authors to speculate that beauty products are the culprit.
In the meantime, if must get a manicure, study author Kate Hoffman warns people to avoid getting the polish on your skin so the chemical doesn’t enter your bloodstream. Then, you’re good to go!
