TPHP, also known as TPP, is commonly used as a fire retardant in furniture and a hardener in plastic goods. According to the authors, research suggests that the chemical causes changes in hormone regulation, metabolism, and reproductive systems.
The study, published today in Environmental International, found that women who painted their nails with polishes containing TPHP saw a sevenfold increase of a TPHP metabolite (a substance formed when the body metabolizes TPHP) just 10 to 14 hours after painting their nails.
