It comes as no surprise that nail polish is toxic. The smell alone can give that away. But new research is showing that one of these toxic chemicals could be causing more damage than originally thought.

A new study from Duke University is showing that one of these chemicals is actually ending up in the body. Triphenyl phosphate (TPHP) is more commonly used as a fire retardant in foam furniture and to make plastics. It is also known as an endocrine-disrupting chemical, and this is the one showing up in individuals’ bodies.

Twenty-six women had urine tested both before and after an application of TPHP containing nail polish. The findings were that the levels of TPHP in the urine increased dramatically post nail polish application. Not only does this mean that you can have short term exposure, but with continued nail polish use this can lead to even more effects of long term exposure.

As said before TPHP is known to be an endocrine-disrupting chemical meaning it can disrupt the functioning of hormone in the body and possibly even the reproductive and developmental processes. Young girls before and during puberty are even more susceptible to these types of chemicals. Before applying that second or third coat of nail polish you might just want to check if the brand you are using is one containing this chemical.
