Why the chemical composition of baby products deserves real attention
When choosing a playmat, a baby bath, or a training potty for their child, people often think first about dimensions, colors, or price. The question of chemical composition rarely comes first, even though it directly impacts the baby's daily safety. An infant spends hours lying on a mat, putting objects in their mouth, bathing in water that remains in contact with a plastic tub. The substances present in these materials are not harmless.
This article aims to demystify three families of substances often cited in technical data sheets and safety labels: formamide, BPA, and phthalates. Understanding what they are, why they pose a problem, and how to verify their absence will enable you to make informed choices, without getting lost in inaccessible technical jargon.
Formamide: primarily present in EVA foams
Formamide is an organic compound used as a blowing agent in the manufacture of ethylene-vinyl acetate foams, better known by the acronym EVA. This foam is widely used in childcare products: interlocking playmats, floor mats, bath toys, shoe soles. Its lightness and shock-absorbing capacity make it a material of choice for environments where babies crawl, fall, and explore.
The problem with formamide is twofold. First, it can evaporate at room temperature, especially in the first few weeks after purchase or in poorly ventilated rooms. Second, studies have shown potentially toxic effects on the reproductive system and development. The European Chemicals Agency (ECHA) has classified formamide as a substance of very high concern.
What regulations apply in Europe?
In France and the European Union, the REACH regulation governs the use of chemical substances in consumer products. Since 2012, France has banned the sale of EVA foam floor mats for children containing more than 200 mg/kg of formamide. The European Commission subsequently extended similar restrictions across Europe. Concretely, a product compliant with REACH regulations must certify that its formamide content is below this threshold. However, minimal regulatory compliance does not mean total absence: some labels go further by requiring an undetectable content.
How to check?
The mention 'Formamide-free' on a product sheet should ideally be accompanied by an independent laboratory test. OEKO-TEX STANDARD 100 certification, although primarily known for textiles, also applies to certain composite materials. For foams, look for chemical analysis reports (COA, Certificate of Analysis) or explicit mention in downloadable technical data sheets.
BPA: a known substance, still too present
Bisphenol A, or BPA, is a chemical compound used in the manufacture of many rigid polycarbonate plastics, as well as in the internal coatings of certain containers. It has historically been found in baby bottles, pacifiers, children's dinnerware, hard toys, and water tanks.
BPA is a recognized endocrine disruptor: it mimics the action of estrogens in the body and can interfere with hormonal development, especially in fetuses and very young children whose biological systems are under construction. Exposure occurs mainly through ingestion, when BPA migrates into food or liquids in contact with plastic, especially when heated.What European regulations say
BPA has been banned in polycarbonate baby bottles since 2011 in Europe. Since 2020, its use has been severely restricted in toys and childcare articles for children under 36 months. However, some products manufactured outside the EU and sold online do not always comply with these restrictions. The mention 'BPA-free' therefore remains a relevant selection criterion, provided it is supported by actual CE compliance and not merely declarative.
BPA substitutes: caution advised
Bisphenol S (BPS) and bisphenol F (BPF) are often presented as alternatives to BPA. Recent research suggests that they share some similar endocrine-disrupting properties. A product bearing only the mention 'BPA-free' without specifying the nature of the plastic used deserves further investigation. PP (polypropylene) and PETG plastics are generally considered safer alternatives for items in contact with liquids.
Phthalates: plasticizers to be closely monitored
Phthalates are a family of chemical compounds used as plasticizers, primarily in flexible PVC. They make plastic flexible, resistant, and easy to mold. They are found in many childcare items: teething rings, soft plastic toys, raincoats, bath accessories.
Several phthalates are recognized as endocrine disruptors and potential carcinogens. DEHP, DBP, and BBP are the three most concerning phthalates, classified as substances of very high concern by ECHA. Like BPA, they migrate into the body through prolonged skin contact or ingestion, two very common exposure routes for infants who put everything in their mouth and whose skin easily absorbs external substances.What REACH regulations cover
REACH regulations set strict limits on the concentration of phthalates in toys and childcare articles: less than 0.1% for DEHP, DBP, and BBP in any article that can be put in a child's mouth. These thresholds apply to products placed on the European market, but their verification relies on laboratory tests that not all manufacturers systematically perform, particularly for small players or unscrupulous importers.
Recognizing phthalate-free products
OEKO-TEX, Bluesign certifications, or REACH tests attested by accredited laboratories (SGS, Intertek, Bureau Veritas) offer a solid guarantee. For products in contact with water, such as a baby bath, check that the material is polypropylene or ABS rather than PVC, and that the technical sheet explicitly mentions the absence of phthalates. The Treelys foldable bathtub is designed with materials selected to meet these requirements and accompany baby's first years without compromising on chemical safety.
Reading certifications as a filter of trust
Faced with the proliferation of labels and marketing claims, it is useful to prioritize certifications according to their actual level of requirement.
CE marking
CE marking is mandatory for any product placed on the European market. It certifies that the manufacturer declares its conformity with applicable European directives. It is a minimum legal threshold, not a superior quality label. Its absence is prohibitive; its presence alone is not sufficient.
REACH compliance
REACH is the European reference regulation on chemical substances. A 'REACH compliant' product has been verified against the list of substances of very high concern. This is a more substantial guarantee than simple CE marking for everything related to chemical composition.
OEKO-TEX STANDARD 100
This independent label tests every component of an article (including threads, buttons, dyes) against a list of over 100 harmful substances. It applies primarily to textiles but extends to certain composite materials. For a playmat with a textile cover, this is a particularly relevant certification. Our Treelys playmat was developed taking into account these standards to guarantee a healthy play surface from the first months.
Some practical habits for everyday purchases
Here is a simple method to quickly assess the chemical safety of a baby product before buying it:
First, check that the product sheet explicitly mentions the materials used (PP, ABS, XPE, organic cotton, etc.) and not just vague terms like 'quality plastic' or 'safe materials'.
Second, look for precise mentions: 'BPA-free', 'phthalate-free', 'formamide-free', accompanied if possible by a link to a test report or third-party certification.
Third, be wary of very low prices on non-specialized marketplaces for items in prolonged contact with baby. The cost of a serious certification is reflected in the selling price.
Fourth, consult available public resources: the SCENIHR database of the European Commission and the opinions of the High Council for Public Health (HCSP) are accessible to all and provide updated scientific data.

Conclusion: chemical safety, a structuring and non-negotiable criterion
Formamide, BPA, phthalates: these technical names refer to concrete realities that concern the daily lives of every family with a young child. The good news is that tools exist — regulations, certifications, public databases — to distinguish serious products from those that merely use reassuring vocabulary without the technical content that should accompany it. Choosing products whose chemical safety is documented and verifiable is a decision that naturally fits into a more conscious and sustainable consumption approach.
