"BPA or BPS Free" or "Phenol Free" and now "non-phenolic" thermal paper?

 Tiger Claw Supplies is the leader in helping all of us make more informed choices. We are striving to change the thermal paper industry to be more socially and environmentally conscious.

We where the very first company to offer Phenol Free thermal paper over 8 years ago.

Our Phenol Free paper rolls supplied by Koehler Paper in Germany which is a company that is over 200 years old, and has won multiple awards both in sustainability and environmental categories. Their colour developer contains no BPA/BPS or any of their subvariants and or derivatives. Which you will learn about below. 

 We have provided:

1) Link to a brand-new study published in Science Magazine

2) An except from a study in Europe in 2020 from the British Occupational Hygiene Society.

 

1)There is some brand-new research out showing cellular decay from exposure to some of the Bisphenol-A "alternatives" being used by paper mills in production of thermal paper rolls. These chemicals are still in the "Phenol Family" of chemicals": If your paper says BPA FREE & BPS FREE it could be still using these types of chemicals.

Abstract

Objectives: Bisphenol A (BPA) is the most used colour developer in thermal paper for cashier’s receipts, labels, and tickets. BPA can migrate onto the skin and be absorbed when handling these papers. BPA is a known endocrine disruptor and is therefore being replaced in thermal paper by some alternatives such as Bisphenol S (BPS), D-8, and Pergafast 201® (PF201). To our knowledge, no studies have characterized skin permeation of these BPA alternatives.

Methods: We measured/characterized skin absorption for BPA, BPS, D-8, and PF201 through ex vivo human skin using flow-through diffusion cells according to OECD guideline 428. Skin samples were 7-12 per test substance from three different skin donors. Skin metabolism was studied for BPA. Dermal absorption was expressed as the amount of the BPA alternatives in the receptor fluid over applied dose in percent (%).

Results: The absorbed dose after 24 h of exposure was 25% for BPA, 17% for D-8, 0.4% for BPS, and <LLOQ for PF201. The amount of BPA-glucuronide in the receptor fluid after 24 h was under the limit of quantification (LLOQ = 0.2 µg l-1). Despite the 10-fold lower concentration of the aq solution applied on the skin, D-8's permeation rate JMAX was 5-fold higher than the one for BPS (0.032 versus 0.006 µg cm-2 h-1). Neither D-8 nor BPS permeated readily through the skin (tlag = 3.9 h for D-8, 6.4 h for BPS). None of PF201's skin permeation kinetic parameters could be determined because this BPA analogue was not quantifiable in the receptor fluid in our test conditions.

Conclusions: Skin absorption was in decreasing order: BPA > D-8 >> BPS > PF201. These results are in agreement with their log Kow and molecular weights. We provided here the necessary data to estimate the extent of skin absorption of BPA analogues, which is a necessary step in risk assessment, and ultimately evaluate public health risks posed by D-8, BPS, and PF201.
