Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
(96 h) LL50 >LoS S. gairdneri and C. auratus
Key value for chemical safety assessment
Additional information
The presence of branched structures does not appear confer aliphatic alcohols any different environmental properties compared to the Alcohols, C14 -15 linears only substance. Therefore the data is freely read-across between Alcohols C14 -15, Alcohols, C14 -15 -branched and linear and Alcohols, C14 -15 -branched substances.
A reliable 96 h LC50 value of >500 mg/L has been determined for the effects of Alcohols, C14 -15 on the mortality of the freshwater fish S. gairdneri (new name: Oncorhynchus mykiss). The concentrations tested were above the limit of solubility (>LoS) of the test substance, so the results should be treated with caution. However the study does indicate the LC50 is >LoS (Shell 1978)
The study from Birdie et al. (1973) tested Alcohols, C14 -15 close to the limit of solubility. Both of these studies are being used as weight of evidence that an LC50 was not achieved at the LoS of Alcohols, C14 -15-branched.
In some cases the CAS and chemical identity stated refer to SDA nomenclature for this substance. In REACH substance identification it is necessary to be more specific as to the chain lengths present. Full details may be found in the CSR.
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).
