Bisphenol S (BPS)
Bisphenol S (BPS) is used as a replacement for bisphenol A (BPA) in food packaging. Little research has been done regarding the potential health risks of using BPS. The limited research available has shown slight negative health effects of consuming BPS.
In recent years, bisphenol analogues like bisphenol S (BPS) have been used to replace bisphenol A in food packaging and containers because bisphenol A (BPA) has been found to leach into food and water, leading to various negative health effects. BPS is a component of polyethersulfone (PES) plastic, which is utilized in the production of hard plastic items and synthetic fibers for clothing and other textiles. BPS may also be used to enhance color longevity in certain fabrics. It is a common substitute for BPA in some types of paper receipts and is also present in protective coatings inside some food cans. Consumer products labeled as “BPA-free” might contain BPS.
Little research has been done to determine the safety of these BPA-free products before they were marketed to the public as a healthier alternative. Although dietary exposure to BPS seemed the least likely to encourage a specific type of breast cancer, cause DNA damage, or impair the immune system, BPS exposure still resulted in these harmful effects compared to the controls.
