Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Key value for chemical safety assessment
Additional information
No studies on the chronic toxicity to fish is available for Fatty acids, C14-18 and C16-18-unsatd., mixed esters with castor oil, castor oil fatty acids, 2-ethylhexanoic acid and 2,2-bis(hydroxymethyl)-1-butanol (CAS No. 92113-48-9). Nevertheless, the acute aquatic toxicity tests of this ester clearly showed no effects occurred in the range of water solubility in fish, daphnia nor algae. Furthermore, only negligible releases into surface waters from sewage treatment plants are expected to take place due to: a) the rapid biodegradability and b) the high adsorption properties and low water solubility’s of this substance, resulting in an effective removal in sewage treatment plants. Therefore chronic exposure of aquatic organisms is unlikely. Furthermore, a chronic study towards Daphnia magna for the read across substance Fatty acids, C14-18 and C16-18 unsatd., triesters with trimethylolpropane (CAS No. 68002-79-9) revealed no effects up to the limit of water solubility. In addition, the ECHA Guidance on information requirements and chemical safety assessment, Chapter R.7b (ECHA, 2012b) states that “chronic fish toxicity testing is generally only necessary, when the P and B criteria are fulfilled” and this is clearly not the case. Hence due to animal welfare reasons and to avoid unnecessary vertebrate tests, no further long-term test with fish is required for this substance.
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.
