Hormone-Altering Cosmetics Chemicals

Laboratory tests from Environmental Working Group (EWG) reveal adolescent girls across America are contaminated with chemicals commonly used in cosmetics and body care products. They were able to detect that 16 chemicals from 4 chemical families - phthalates, triclosan, parabens, and musks - in blood and urine samples from 20 teen girls aged 14-19. Studies link these chemicals to potential health effects including cancer and hormone disruption. These tests feature first-ever exposure data for parabens in teens, and indicate that young women are widely exposed to this common class of cosmetic preservatives, with 2 parabens, methylparaben and propylparaben, detected in every single girl tested.


Emerging research suggests that teens may be particularly sensitive to exposures to trace levels of hormone-disrupting chemicals like the ones targeted in this study, given the cascade of closely interrelated hormonal signals orchestrating the transformation from childhood to adulthood.
