A study led by SUNY Downstate Medical Center’s School of Public Health presents evidence linking personal care products used during pregnancy to adverse reproductive effects in newborns.
“The study found a link between women with higher levels of butyl paraben, which is commonly used as a preservative in cosmetics, and the following birth outcomes: shorter gestational age at birth, decreased birth weight, and increased odds of preterm birth,” says Laura Geer, PhD, MHS, associate professor in the Department of Environmental and Occupational Health Sciences in the School of Public Health at SUNY Downstate.
The antimicrobial compound, triclocarban, mainly added to soaps, was associated with shorter gestational age at birth. Another common chemical added to lotions and creams, propyl paraben, was associated with decreased body length at birth. The long-term consequences of this are not clear, and, Geer adds, “Findings must be reproduced in larger studies.”
The study was a collaboration with SUNY Downstate’s Department of Obstetrics and Gynecology, and the Center for Environmental Security at Arizona State University’s Biodesign Institute, directed by professor Rolf Halden, PhD, a noted expert in the study of antimicrobial chemicals. The findings are available online and will be published in a Special Issue “Emerging Contaminants” in the Journal of Hazardous Materials.
