The Environmental Working Group (EWG) released an alarming new study today showing that Triphenyl phosphate, or TPHP, a suspected endocrine-disrupting chemical, was found in the urine of women who had just polished their nails with polishes containing the common chemical.

OPI, Essie and Sally Hansen are among the list of brands containing TPHP. For the full list, click here.
