A topic that has become central to family decisions
For several years, the issue of endocrine disruptors in products for infants and young children has played an increasingly important role in parents' concerns, as well as in the work of French and European health agencies. ANSES – the French Agency for Food, Environmental and Occupational Health & Safety – has published several expert reports on this topic, contributing to a better understanding of the risks associated with certain chemical substances present in babies' daily environment.
This article provides a factual overview: what available data confirms, what remains under debate, and how families can rely on trusted sources to make informed choices.
What is an endocrine disruptor?
An endocrine disruptor is a chemical substance that interferes with the hormonal system of living organisms. According to the definition adopted by the World Health Organization, it is an exogenous substance or mixture that alters the function of the endocrine system and consequently causes adverse health effects in an intact organism, its offspring, or sub-populations.
Infants and young children are considered particularly vulnerable to these substances for several documented reasons: their immature metabolism limits their ability to eliminate certain compounds, their body surface area is proportionally larger than that of adults, and certain developmental windows – particularly the first weeks and months of life – are periods during which hormonal disruptions can have lasting effects. These observations are widely accepted in international scientific literature.
The most documented substances in childcare products
Phthalates
Phthalates are plasticizers used in many flexible PVC-based materials. They have been identified as endocrine disruptors by several agencies, including ANSES and the European Chemicals Agency (ECHA). Several phthalates are now subject to strict restrictions in toys and childcare articles in Europe, via the REACH regulation and the Toy Safety Directive. These restrictions have led to a measurable reduction in children's exposure to these substances since their entry into force, although studies continue to monitor residual exposure levels.
Bisphenol A and its substitutes
Bisphenol A (BPA) has been banned in baby bottles in Europe since 2011, and its use in food containers for children has been progressively restricted. However, research – some of which is cited by ANSES – highlights that the substitutes used to replace it, particularly bisphenol S (BPS) and bisphenol F (BPF), raise similar scientific questions. To date, the level of evidence on the effects of these substitutes is less established than for BPA, and this area is the subject of active research. It is therefore an ongoing debate, and not a definitive consensus.
Brominated flame retardants
Certain brominated flame retardants, used in textiles and foams in childcare products, have also been evaluated by European health agencies. Several of them have been classified as substances of concern and are subject to progressive restrictions under European chemical regulations.
What ANSES recommends to families
In its communications to the general public, ANSES makes several practical recommendations to limit the exposure of infants and young children to endocrine disruptors. These recommendations are based on the precautionary principle, in areas where evidence is still being consolidated, and on established data for substances whose effects are better documented.
Among the guidelines adopted are: favoring materials with documented and certified composition, avoiding heating food in plastic containers, regularly ventilating young children's living spaces to reduce the concentration of volatile compounds, and choosing products with recognized certifications that attest to the absence of substances of concern. ANSES also provides accessible information sheets on its official website at www.anses.fr.
European regulation: real progress, identified gaps
The European Union has strengthened its regulatory framework on endocrine disruptors in recent years. The REACH regulation, the European Chemicals Strategy for Sustainability published in 2020, and the ongoing revisions of several sectoral directives demonstrate a political will to reduce the exposure of the population – and particularly children – to these substances.
Nevertheless, experts and health agencies, including ANSES, regularly point out that the evaluation of substances is often conducted substance by substance, whereas the actual exposure of individuals is the result of a combination of many compounds. The cocktail effect – i.e., the potential interaction between several substances present simultaneously – is recognized as a major scientific and regulatory issue, even if the methods for evaluating this effect are still the subject of research and methodological debates.
Choosing childcare products: reliable benchmarks
Certifications as a starting point
Given the complexity of the subject, independent certifications provide a useful benchmark for families. Labels such as Oeko-Tex Standard 100, the European Ecolabel, or FSC certifications for wood materials, ensure that a product has been tested according to documented criteria. These certifications do not guarantee the absolute absence of all chemical substances, but they attest to compliance with thresholds and exclusion lists defined by independent third-party organizations.
Durability as a lever for exposure reduction
A less often mentioned but consistent aspect with available data is the lifespan of products. A quality childcare item, designed to last and evolve with the child, mechanically reduces the number of products introduced into the baby's environment. This approach, central to the philosophy of slow parenting documented by research, is also consistent with precautionary recommendations: fewer, better-chosen products represent a strategy for reducing overall exposure.
It is in this logic that products designed to accompany the child for several years fit, such as an activity mat designed to last beyond the first few weeks, or an evolving 3-in-1 potty that follows the child through their developmental stages. Reducing product renewal also means reducing potential sources of exposure.
What parents can take away
Research on endocrine disruptors is an active field, where certainties still coexist with many gray areas. What is known with a good level of evidence: certain chemical substances present in common products can interfere with the hormonal development of infants, and European regulations are progressing to limit their use. What remains under debate: the exact extent of the risks associated with substitutes for banned substances, and the methods for evaluating combined effects.
In this context, the most coherent approach with available data is that of reasoned precaution: relying on recognized certifications, limiting the number of products introduced into the baby's environment, favoring documented materials, and consulting resources from official agencies such as ANSES or the Haute Autorité de Santé for up-to-date and verified information.
