Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 Pseudokirchnerella subcapitata (OECD 201)
Key value for chemical safety assessment
Additional information
One study investigating the short-term toxicity of Mixed esters of fatty acid C16 and C16-C18-unsatd. with adipic acid and pentaerythritol to freshwater algae is available.The GLP study was performed under static conditions according to OECD guideline 201 using Pseudokirchnerella subcapitata as test organism (Bizzaro & Limiroli, 2012). A 100 mg/L test solution was used in a limit test. TOC analysis at 0 and 72 h revealed a stable test substance concentration (26.86 mg TOC/L, arith. mean). No effects were observed after 72 h. Hence the 72 h-EC 50 is determined to be >100 mg/L and the 72 h-NOEC is determined to be ≥ 100 mg/L based on 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 Mixed esters of fatty acid C16 and C16-C18-unsatd. with adipic acid and pentaerythritol.
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.
