A study suggests compounds from some infant bath care products can be absorbed through babies' skin. However, it's unclear what the health consequences of this may be, if there are any at all.
Researchers at the University of Washington found use of baby lotions, shampoos and powders were strongly associated with higher levels of the chemical compounds called phthalates in the urine of babies.
Phthalates are added to many personal care and cosmetic items, as well as some common household plastic and vinyl products. Manufacturers are not required to list phthalates on labels in this country.
All of the 163 babies in the study had detectable levels of at least one phthalate in their urine. At least 7 phthalates were detected in 80-percent of babies.
Some animal studies of phthalates have indicated the compounds might harm reproductive system development, but human exposure has not been extensively studied.
