ANSES is proposing a harmonised classification for galaxolide, sometimes referred to as HHCB, as a Category 1B reproductive toxicant under the CLP Regulation (for Classification, Labelling and Packaging of products). This substance, which is widely used in everyday products such as perfumes, cosmetics and air fresheners, can cause damage to human fertility and development, according to the conclusions of ANSES’s expert appraisal work. Since 27 January 2025, the scientific dossier has been available for public consultation on the website of the European Chemicals Agency (ECHA), for comments or provision of additional information on this substance.
