EC number: 219-863-1 | CAS number: 2554-06-5
The chemical safety assessment according to REACH Annex I indicates that it is not necessary to conduct the simulation test on ultimate degradation in surface water and the sediment simulation test, or to identify degradation products. Simulation tests (water and sediments) are not considered necessary because the risk characterisation ratios (RCRs) for the aquatic and sediment compartment, even with the realistic assumption that the parent substance is not biodegradable, are <1.
The registration substance has an average purity of >80% Vi4-D4, with <15% 2,4,6,8,10-pentamethyl-2,4,6,8,10-pentavinylcyclopentasiloxane (Vi5-D5; CAS 17704-22-2; Impurity 1) and <10% 2,4,6-trimethyl-2,4,6-trivinylcyclotrisiloxane (Vi3-D3; CAS 3901-77-7; Impurity 2) present as impurities. The data waiver applies for both the main constituent and the impurities.Additional information is given in a supporting report (PFA, 2017) attached in Section 13 of the IUCLID 6 dossier.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
