EU Commission closes its proposal to nominate siloxanes D4, D5 and D6 under the Stockholm Convention

The European Commission’s international agreements page indicates the Commission decided to close its proposal to nominate octamethylcyclotetrasiloxane (D4), decamethylcyclopentasiloxane (D5), and dodecamethylcyclohexasiloxane (D6) for listing under the Stockholm Convention. For compliance and horizon-scanning teams, this signals that this specific EU-driven nomination pathway has been halted, potentially changing expectations/timelines for any future Stockholm Convention consideration of these substances via that route.
