"The featured research now shows that when combined, you create a situation in which your body absorbs the greatest amounts of toxin possible... First of all, absorption of BPA via your skin promotes higher levels of biologically active BPA in your body, compared to ingesting it via contaminated food.
"When scientists added in two other factors—scrubbing hands with hand sanitizer and eating greasy food—the evidence points to a super-sized dose of BPA," Time Magazine notes.'The chemicals used to make hand sanitizers, soaps, lotions, and sunscreen degrade the skin's ability to act as a barrier and so act as skin penetration enhancers,' says [study author] vom Saal.So BPA enters the body more efficiently than it would otherwise. Food grease and other oils can act similarly because BPA itself is fat-soluble..."
Remarkably, absorption of BPA occurred in people holding a receipt for as little as TWO SECONDS! According to the author of the study, the amounts of BPA absorption found in his research "are in a zone where effects associated with obesity, diabetes, and neurological effects can result."
Past research also suggests caution is warranted when handling receipts, even if you only hold them long enough to put them in your wallet. A 2010 study in Analytical and Bioanalytical Chemistry3 found that of 13 thermal printing papers analyzed, 11 contained BPA.
In that study, holding the paper for five seconds was enough to transfer BPA to a person's skin, and the amount of BPA transferred increased by about 10 times if their fingers were wet or greasy (such as if you've just applied lotion or eaten greasy food)."
