What Does "BPA-Free" Mean? Why the Label Alone Isn't Enough

In short: "BPA-free" only means that no bisphenol A is present. Whether BPS, BPF or other substances were used instead is not stated on the label – and that is exactly the decisive question for parents.

What does BPA-free actually mean?

You buy a new water bottle, flip it over, see the "BPA-free" symbol – and think: good, that's settled. But the label only answers one of several relevant questions.

What "BPA-free" actually means

"BPA-free" means exactly that: no bisphenol A. It doesn't automatically mean a product is free of other bisphenols – such as BPS (bisphenol S) or BPF (bisphenol F), which some plastics use as substitutes. It also says nothing about overall material quality, durability or how the product behaves after extended use.

Why BPA became an issue in the first place

Bisphenol A was used for decades in the production of hard polycarbonate plastic. The concern: BPA can act like a hormone and transfer into the body – especially when plastic is heated or scratched. Since 2011, BPA has been banned in baby bottles in the EU, and most manufacturers have since removed it from kids' products.

The problem with the substitutes

When BPA is removed, it gets replaced with something else. Often BPS or BPF – structurally related compounds. Early studies suggest these substitutes may share similar properties with BPA. The research isn't conclusive yet.

"BPA-free" describes what isn't in the product. What is used instead isn't on the packaging.

What BPS and BPF are exactly and what the EU has banned in the meantime is explained in detail here: BPA-free and still a concern?

And then there's microplastics

Another point often overlooked when it comes to plastic and children's health: microplastics. Plastic products shed small particles during use – through mechanical wear from opening, cleaning and daily handling. The more intensively a product is used, the more wear can build up over time.

Kids' products get used especially intensively. A water bottle that is filled daily, thrown into a backpack and washed every evening experiences more mechanical stress than a comparable adult product.

Studies have found more microplastic particles in drinks from plastic bottles than in those from glass or stainless steel. The long-term health effects aren't fully researched yet – but less plastic contact at least reduces one avoidable source.

What offers more guidance

Plastic products that meet the requirements of the EU Plastics Regulation (EU) No 10/2011 have undergone broader material testing than those carrying only the "BPA-free" label. This regulation specifically governs plastics in contact with food and is part of the wider EU framework for all food-contact materials, Regulation (EC) No 1935/2004.

Materials that structurally contain no bisphenols and don't shed microplastics through wear are stainless steel and glass. With both, these questions simply don't come up.

When plastic is still a sensible choice

Especially for young children, where the weight of stainless steel can be a real obstacle, plastic is often the more practical choice. In that case: don't heat it in the microwave, treat scratches as a signal to replace it, and prefer plastic products that meet the EU Plastics Regulation (EU) No 10/2011.

What parents can watch for

Treat "BPA-free" as a minimum requirement, not a mark of quality.

For plastic, look for compliance with the EU Plastics Regulation (EU) No 10/2011.

Consider stainless steel or glass for products used daily.

Don't heat plastic products at high temperatures.

Visible scratches on the inside are a signal to replace the product.

Frequently asked questions

Does "BPA-free" mean safe for kids? "BPA-free" means no bisphenol A is present. Substitutes like BPS or BPF are often used instead, and their long-term effects are still being researched. For complete freedom from bisphenols, stainless steel or glass are the better choice.

What are microplastics, and why do they matter for kids' products? Microplastics form through mechanical wear during normal use of plastic products. Kids' products get used intensively, which increases wear. Stainless steel doesn't shed microplastics during normal use.

What's the difference between "BPA-free" and the EU Plastics Regulation? "BPA-free" is a single exclusion criterion. The EU Plastics Regulation (EU) No 10/2011 is a broader assessment of a material's suitability specifically for plastics in contact with food. The overarching framework for all material types – plastic, stainless steel, glass and more – is Regulation (EC) No 1935/2004.

Are stainless steel products free of bisphenols and microplastics? Food-safe 304 stainless steel contains no bisphenols and doesn't shed microplastics during normal use. It's considered a proven material for food contact.

Do I need to replace all my plastic products right away? No. Well-maintained, compliant plastic products are fine for everyday use. Once they show scratches, discolouration or a persistent smell, it's worth replacing them.

Quick summary for parents

• "BPA-free" only means: no bisphenol A – not: no bisphenols at all
• The substitutes BPS and BPF haven't been fully researched yet
• Microplastics can form through wear during normal use of plastic products
• Stainless steel contains no bisphenols and sheds no microplastics
• The EU Plastics Regulation (EU) No 10/2011 offers more guidance for plastics than the "BPA-free" label alone; the overarching Regulation (EC) No 1935/2004 covers all material types
