A new study led by primary investigator Michael S. Bloom, professor in the Department of Global and Community Health at George Mason’s College of Public Health, has found that use of skin care products including lotions, hair oils, hair conditioners, ointments, and sunscreen is associated with higher levels of phthalates in children’s urine. The associations depend in part upon the child’s racial and ethnic identity and their sex as assigned at birth. The study was co-authored by two George Mason Master of Public Health alumni, Juliana Clark and Kelly Garcia.
"This is the first study to suggest that different skin care products used by young children may differentially increase exposure to endocrine-disrupting phthalates and phthalate replacements in young children," said Bloom.
Phthalates and phthalate-replacement compounds are endocrine-disrupting chemicals, meaning they may interfere with the body’s hormones. Exposure to these chemicals in early childhood has been associated with neurodevelopmental, reproductive, and metabolic disease concerns in previous studies. Some of these chemicals are often used as carriers for the active ingredients in skin care products; others may be used in plastic packaging.
