Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Additional information
The short-term EC50/LC50 values for Daphnia and algae were 2.6 and 30 mg/L, respectively as derived from a read across source substance. Further studies are not needed for this tonnage band.
Since the read across source substance showed highest ecotxicity in fish (96h-LC50= 0.73 mg/L), the fish study for the read across source substance was considered as well for conservative reasons.
Read across is made from CAS 147993-66 -6 (source) to the target substance CAS 90268-39-6. Both substances have a similar C-chain distribution but CAS 147993-66-6 has a higher content of unsaturated C18 (C18´) when compared to the substance CAS 90268-39-6. For this sulfosuccinates group, higher degree of unsaturation was associated with higher ecotoxicity of CAS 147993-66-6. CAS 147993-66-6 is the substance showing highest ecotoxicity in the monoester group. For the sake of being conservative read across is made from the more unsaturated substance (CAS 147993-66-6) to the more saturated substance (CAS 90268-39-6). Since the read across is considered to be conservative, assessment factors are not needed.
Further information is provided in the read acorss documentation in IUCLID chapter 13..
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.
