Bisphenol S (BPS) is a key component in the production of polyethersulfone (PES) plastic, a material used to manufacture hard plastic products and synthetic fibers found in clothing and various textiles. It is also added to certain fabrics to help colors last longer. Beyond plastics and textiles, BPS has become a common substitute for bisphenol A (BPA) in thermal paper receipts and appears in protective coatings inside some food cans.

Chemically, 4,4′-sulfonyldiphenol, another name for BPS, is a sulfone compound derived from diphenyl sulfone, where both para-position hydrogens are replaced by hydroxy groups. It is classified as both a sulfone and a bisphenol and is known to function biologically as a metabolite and an endocrine disruptor due to its structural similarity to other hormone-interfering chemicals.

• BPS has the molecular formula (HOC₆H₄)₂SO₂ and a molar mass of 250.27 g/mol. Under normal conditions, it appears as a white, colorless solid with a density of 1.3663 g/cm³ and melts at 240–250 °C. It dissolves freely in aliphatic hydrocarbons and is soluble in solvents such as ethanol, isopropyl alcohol, acetonitrile, and acetone, while exhibiting only slight solubility in aromatic hydrocarbons.

Although BPS is widely used as a replacement for BPA in consumer products, research on its behavior and health effects lags behind the extensive studies conducted on BPA. Existing evidence shows that BPS is now widespread in the environment and has been detected globally, though its levels are generally lower than BPA in media such as water, sediments, sludge, indoor dust, air, and consumer goods, as well as in human urine.

Emerging Trends

Scrutiny of BPA-free BPS in receipts and everyday papers

Bisphenol S has quietly become the workhorse behind many BPA-free labels, especially on receipts and other coated papers. An ECHA survey estimated that about 61% of all thermal paper in Europe contained BPS as the main replacement for BPA. Regulators and toxicologists are now treating this as a classic case of regrettable substitution.

• The European Food Safety Authority has modelled typical daily dermal exposure from handling BPS-based receipts at about 0.059 µg per kg of body weight, which may sound tiny but is continuous for cashiers and other workers. At the same time, biomonitoring studies and animal work point toward endocrine-disrupting and reproductive effects similar to BPA.

A shift away from single-substance bans (only BPA) toward group-based measures that also capture BPS and other bisphenols, and a push for non-bisphenol developers like vitamin-C-based papers or fully digital receipts. For producers of BPS, the short-term story is high use in thermal papers and some polymers; the longer-term story is mounting pressure to redesign formulations so that BPA-free genuinely means lower hormonal risk, not just a different bisphenol in the coating.

Drivers

BPA phase-outs are pushing short-term demand for BPS

The main force that pushed Bisphenol S into the spotlight was not its performance alone, but the global retreat from BPA. In the EU, BPA has been restricted in thermal paper, with a full ban on BPA-containing thermal receipts entering into force, forcing paper makers to switch developers in only a few years. Many printers, paper mills, and brand owners chose BPS because its chemistry is close to BPA, so existing curing and printing lines needed minimal tweaking.

• Human biomonitoring underscores how strong that adoption wave has been. In the US National Health and Nutrition Examination Survey (NHANES), BPS was detected in 89.4% of urine samples from the general population, based on 1,808 adults and 868 children, alongside similarly high detection rates for BPA. This tells us BPS has spread well beyond niche industrial applications into everyday exposure, including from receipts, food-contact coatings, and textiles.

Industry has leaned on BPS because it offers heat stability and compatibility with high-performance materials like polyethersulfone and certain epoxy systems used in cans, filters, and electronics. When retailers and FMCG brands committed publicly to BPA-free packaging, resin producers and converters needed a drop-in building block that preserved product performance and avoided immediate supply chain disruption.

Restraints

Health concerns and group restrictions are closing in on BPS

Toxicologists have highlighted that BPS shows estrogen-like activity and reproductive toxicity in several experimental systems, leading European and national regulators to treat it much more cautiously. The European Chemicals Agency added 4,4′-sulphonyldiphenol (Bisphenol S) to the REACH Candidate List as a substance of very high concern for reproductive toxicity and endocrine-disrupting properties in humans and the environment.

• Switzerland has already banned BPS in thermal paper above a specified concentration, effectively phasing it out of receipts nationally. The UK’s Health and Safety Executive has gone further by proposing a group restriction that would cap the concentration of several bisphenols, including BPS, in articles and mixtures at 0.02% by weight, with additional limits on release rates over a product’s life.

Across the Atlantic, a new study for the Center for Environmental Health in the US showed that simply holding a BPS-coated receipt for 10 seconds could lead to skin absorption above California’s Proposition 65 safety threshold, prompting violation notices to roughly 50 major retailers. That kind of public pressure, combined with SVHC listing and national bans, is a clear commercial restraint.

Opportunity

Safer, tightly-controlled niches and circular design for BPS-based polymers

Even as broad consumer uses come under pressure, there is still a window of targeted opportunity for Bisphenol S in highly controlled, technical applications, especially where migration into food or direct human contact can be kept near zero and where recycling rules push industry toward durable, trackable materials.

The EU’s new Regulation (EU) 2022/1616 on recycled plastic food-contact materials demands that recycling processes keep contaminants under strict control and demonstrate safety before authorisation. In parallel, the broader Packaging and Packaging Waste Regulation aims to make all EU packaging recyclable and to safely increase the use of recycled plastics.

• The new Bisphenol Regulation (EU) 2024/3190, BPA and other hazardous bisphenols are broadly banned in food-contact materials, but very limited exemptions remain for critical applications like polysulfone filtration membranes and large-volume epoxy linings, provided migration into food is non-detectable and capacity exceeds 1,000 litres.
