Registry of SVHC intentions until outcome

The registry of SVHC intentions until outcome aims to make interested parties aware of the substances for which an SVHC dossier is planned to be submitted to ECHA.

Member States, or ECHA at the request of the European Commission, may propose a substance to be identified as a substance of very high concern (SVHC) by preparing a dossier in accordance with the requirements set out in Annex XV to REACH.

Interested parties can follow the progress of a proposal through the SVHC identification process, from the notification of the intention until the outcome. The advance notice gives interested parties time to prepare for commenting later in the process.

Interested parties with relevant information on the identity or hazard properties of the substance may submit such information during the consultation.

Perfluorobutane sulfonic acid (PFBS) and its salts

EC / List no: 799-977-0 CAS no: -

The combined intrinsic properties justifying the inclusion as a substance for which there is scientific evidence of probable serious effects to human health and the environment which give rise to an equivalent level of concern are the following: very high persistence, high mobility in water and soil, high potential for long-range transport, and difficulty of remediation and water purification as well as moderate bioaccumulation in humans. The observed probable serious effects for human health and the environment are thyroid hormonal disturbances and reproductive toxicity seen in rodents, and effects on liver, kidney and haematological system in rats, hormonal disturbances and effects on reproduction in marine medaka fish and effects on expression of hormone receptors in tadpoles. Together, these elements lead to a very high potential for irreversible effects.
