The conclusion was based on the findings of a study into feminine hygiene products by the French Chemicals Agency (see ANSES OPINION on the safety of feminine hygiene products & Feminine hygiene products: composition and toxic shock syndrome, our recommendations | Anses - Agence nationale de sécurité sanitaire de l’alimentation, de l’environnement et du travail ) which did not find any risk associated with the presence of the substances tested for, and a related study by the Swedish Chemicals Agency (see kemi.se/download/18.6df1d3df171c243fb2331064/1589120703821/report-8-18-survey-of-hazardous-chemical-substances-in-feminine-hygiene-products.pdf & New report: No reason for concern about chemicals in menstrual products - Kemikalieinspektionen ) that concluded that the risk to human health of the 61 substances that were identified was low (although investigated, no per- and polyfluoroalkyl substances, PFAS, were found).
