BPA & bisphenol substitutes
Hardening agents in polycarbonate plastic and can linings that leach more when heated or scratched.
Also listed as: bisphenol A, BPS, BPF, polycarbonate, epoxy lining
What it is
Bisphenol A gives rigid plastics clarity and strength and forms the epoxy resin lining most metal food cans. Regulatory pressure pushed manufacturers toward BPS and BPF, which are structurally similar.
Why it's worth avoiding
Bisphenols leach into food and drink, accelerating with heat, acidity and abrasion. 'BPA-free' often means a substitute with comparable hormonal activity was used instead.
What the evidence says
EFSA cut its tolerable daily intake for BPA by a factor of 20,000 in 2023, concluding that current dietary exposure is above the safe level for all age groups. In-vitro studies show BPS and BPF have oestrogenic activity of the same order as BPA.
How it's regulated
BPA is banned in the EU in infant bottles, sippy cups and thermal paper, and the EU adopted a broad food-contact ban in 2024. France restricts BPA in all food packaging.
Label clues
- Recycling code 7 or 'PC' / polycarbonate
- 'BPA-free' with no statement about BPS/BPF
- Canned food with no 'non-epoxy lining' or 'BPA-NI' note
- Glossy thermal receipts (a significant dermal source)
Safer swaps
- Borosilicate glass and 18/8 stainless-steel bottles and containers
- Cartons, jars or dried/frozen alternatives to canned goods
- Brands stating a specific alternative lining (acrylic, oleoresin, polyester)
- Digital receipts instead of thermal paper
Where it shows up
Frequently asked
Is BPA-free plastic safe?+
Not automatically. If the replacement is BPS or BPF, the hormonal activity is broadly similar. Glass and stainless steel avoid the question entirely.
Does dishwashing make it worse?+
Yes. Heat and abrasion accelerate leaching from polycarbonate. Hand-wash old plastic, and replace anything cloudy, scratched or crazed.

How to spot BPA & bisphenol substitutes on a label
BPA & bisphenol substitutes rarely appears under that exact name on packaging. Manufacturers use trade names, umbrella terms such as "fragrance" or "performance finish", or simply omit process chemicals that are not classed as intentional ingredients. That is why reading a claim ("free from", "non-toxic", "natural") tells you far less than reading the composition and the certifications behind it.
The practical approach is to work backwards from certifications that test finished products rather than from ingredient lists alone. A scheme with residue limits and third-party lab testing catches substances that a marketing claim will never mention, including contamination introduced during dyeing, coating or packaging.
Exposure also depends on use. The same substance matters much more in something worn against skin all day, heated, chewed, or used on broken skin than in a rigid object handled briefly. Judge risk by contact, duration and temperature, not by the scariness of the name.
Claim vs. verification
| What you see | What it proves | What to do |
|---|---|---|
| “Free from” on the front of pack | Nothing verifiable on its own — unregulated wording | Look for a named standard or test method |
| Full ingredient or fibre list | Intentional inputs only, not process residues | Cross-check against a residue-tested certification |
| Third-party certification | Audited limits, usually with lab testing | Confirm scope, product line and expiry date |
| Published test report | Strongest evidence available | Check the lab, the date and the method used |
Safer-swap checklist
- Prefer residue-tested schemesOEKO-TEX, GOTS and equivalents set limits and test finished goods.
- Cut the coatingsStain-, water- and wrinkle-resistant finishes are the most common carriers of unwanted chemistry.
- Mind the heatHeat and abrasion increase migration; choose plainer materials for anything hot or worn.
- Ask for the certificateA brand that holds one will send the number; a brand that does not will change the subject.
