Sans BPA Pourquoi Ça Compte

Bisphenol A

Le bisphénol A (BPA) est un produit chimique controversé, qui se trouve dans le revêtement interne de boîtes alimentaires, de certaines bouteilles à eau et d'autres produits. Certains chercheurs ont établi un lien entre ce produit chimique considéré comme un perturbateur hormonal et une quantité de problèmes, notamment des effets sur le comportement et le développement chez les enfants. Thermos ne prend pas de risque et s'est engagé à produire exclusivement des produits sans BPA.
