Is the BPA-free coating on receipt paper actually safer for your skin?

What's actually in it

Thermal receipt paper, the kind printed at checkout, used to be coated with BPA. When BPA was restricted, many companies switched to BPS. Now some are switching again to Pergafast 201, a urea-based color developer. It's used on receipts from grocery stores, gas stations, ATMs, and restaurants.

Cashiers handle hundreds of receipts per shift. Shoppers touch them briefly but repeatedly. Both groups absorb whatever is on the paper through their fingertips.

What the research says

A 2026 study in Environ Int tested how Pergafast 201 behaves on viable human skin, comparing it directly to BPA and BPS. The researchers used actual human skin samples, not synthetic membranes, making the results highly relevant.

Pergafast 201 was absorbed through the skin and metabolized into breakdown products. The absorption rate and metabolism pattern were comparable to BPA and BPS. The skin didn't treat this "safer" chemical any differently than the ones it replaced.

The study found that skin enzymes actively processed Pergafast 201, creating metabolites whose safety hasn't been thoroughly studied. Getting absorbed is the first step to causing harm: once a chemical passes through the skin, it enters the bloodstream.

The simplest protection is to decline paper receipts and opt for digital ones. If you must handle receipts, wash your hands afterward, especially before eating. Cashiers should consider wearing nitrile gloves during shifts.
