Key value for chemical safety assessment
Additional information
In a biomimetic extraction screening study conducted using WAFs at 100 mg/L loading rate a TDAE sample of solvent refined heavy paraffinic distillate solvent (CAS# 68783-04-0) did not have a positive BE result (i.e. non-detect)(ExxonMobil, 2010c). A subsequent key 72-hour algal study (OECD 201, KS=1) with Pseudokirchneriella subcapitata (formerly Selenastrum capricornutum) at 100 mg/L loading rate was carried out on this sample. The 72-hour EL50 was > 100 mg/L (ExxonMobil, 2010b).
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
