Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Analysis after hydrolysis revealed three products; two chemicals with moderate water solubility, crotononitrile (CAS# 4786-20-3) and tetrafluoroborate anion (tetrafluoroboric acid, CAS# 16872-11-0), along with the poorly soluble chemical, dodecyl ethyl sulfide (No CAS#). Because of the differential solubilities of the hydrolysis products and formation of an oily phase, it was determined that the aquatic toxicity tests could not be conducted on the parent material as the insoluble materials could not be removed while maintaining a consistent series of exposures. Test data on the hydrolysis products in pure form was collected instead. In the case of dodecyl ethyl sulfide, the pure material is not commercially available. Dodecyl methyl sulfide was substituted as the closest available surrogate. Short-term toxicity testing results for these hydrolysis products follow in subsequent sections.
Additional information
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.
