PFAS

Startling Research Shows That Toxic “Forever Chemicals” Can Penetrate Human Skin

A recent study has shown that PFAS, toxic chemicals used in many consumer products, can be absorbed through the skin into the bloodstream, challenging previous assumptions and highlighting the need for further research on these ‘forever chemicals.’

PFAS are used widely in industries and consumer products from school uniforms to personal care products because of their water and stain-repellent properties. While some substances have been banned by government regulation, others are still widely used and their toxic effects have not yet been fully investigated.

“Our research shows that this theory does not always hold true and that, in fact, uptake through the skin could be a significant source of exposure to these harmful chemicals.” The amount absorbed seemed to correlate with the length of the carbon chain within the molecule. Substances with longer carbon chains showed lower levels of absorption, while compounds with shorter chains that were introduced to replace longer carbon chain PFAS like PFOA, were more easily absorbed. Absorption of perfluoro pentanoic acid for example was four times that of PFOA at 59%.
