Apparently, these BPA free receipts contain bisphenol S, which is also a potential endocrine disruptor but even less is known about it than BPA.
Here are some tips from the EWG to reduce your exposure to BPA and potentially bisphenol S and other chemicals in receipt paper:
- Minimize receipt collection by declining receipts at gas pumps, ATMs and other machines when possible.
- Store receipts separately in an envelope in a wallet or purse.
- Never give a child a receipt to hold or play with.
- After handling a receipt, wash hands before preparing and eating food (a universally recommended practice even for those who have not handled receipts).
- Do not use alcohol-based hand cleaners after handling receipts. A recent study showed that these products can increase the skin's BPA absorption (Biedermann 2010).
- Take advantage of store services that email or archive paperless purchase records.
- Do not recycle receipts and other thermal paper. BPA residues from receipts will contaminate recycled paper.
- If you are unsure, check whether paper is thermally treated by rubbing it with a coin. Thermal paper discolors with the friction; conventional paper does not.
