In a recent study conducted by Duke and EWG - The study, published today in Environment International, found that all of the more than twenty four women in the biomonitoring study had TPHP in their bodies just 10 to 14 hours after painting their nails.
Nail polishes are the only product with TPHP as an ingredient. But it is not only the mass brands like wet n wild, Sally Hanson, Essie and OPI, it is sometimes used as a replacement for phthalates in "cleaner" nail polish brands like RGB and Butter.
TPHP has caused reproductive and developmental problems in animal studies, is a suspected endocrine disruptor and may contribute to weight gain and obesity.
As a clean beauty retailer I will say this - to be TRULY safe - go without nail polish. It is the only way to know that you toxins aren't entering your body. However, if you have to paint your nails - choose as clean of a product as you can get and use 8 free and TPHP-free brands.
