Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
EC10 (16 h) > 10000 mg/L (nominal, WAF) for growth inhibition of Pseudomonas putida (ISO 10712)
Key value for chemical safety assessment
Additional information
One study investigating the toxicity of Fatty acids, C18-unsatd, dimers, hydrogenated, diisopropyl esters (CAS 103213-20-3) to microorganisms is available. The GLP study is performed under static conditions according to ISO 10712 investigating the growth inhibition of the substance to Pseudomonas putida (Bertens, 1998). Loading rate WAFs of 310 to 10000 mg/L are tested. No growth inhibition above 5% (compared to the control) was observed in any treatment over an exposure period of 16 h. Hence, the EC10 (16 h) was determined to be > 10000 mg/L based on the nominal concentration. No inhibition of the degradation process in sewage treatment plants is anticipated.
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.
