Summary

This study looks at whether using special personal care products for just 5 days can reduce levels of certain chemicals (phthalates, phenols, glycol ether) in urine. Researchers will track 107 women aged 18-30 in Grenoble, France, measuring chemical levels before, during, and after the switch. The goal is to understand how everyday products affect our bodies and identify barriers to making healthier choices.
