Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No toxic effects up to the limit of water solubility (< 1 mg/L) for Desmodesmus subspicatus (OECD 201)
Key value for chemical safety assessment
Additional information
One study investigating the toxicity of Fatty acids, C16-18 and C18-unsatd., mixed esters with adipic acid and trimethylolpropane (CAS No. 91001-61-5) to freshwater algae is available. The static study was conducted according to OECD guideline 201 using Desmodesmus subspicatus as test organism (Häner, 2006). A 100 mg/L WAF was tested in a limit test. The 72 h-EL50 is determined to be > 100 mg/L and the 72 h-NOELR is determined to be ≥ 100 mg/L on the basis of the nominal test concentration.
Based on this result it can be concluded that no toxicological effects on algae are expected up to the limit of water solubility for Fatty acids, C16-18 and C18-unsatd., mixed esters with adipic acid and trimethylolpropane.
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).
