Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
EC50 (72 h) for growth rate > limit of solubility of test item under test conditions
NOEC (72 h) for growth rate > = limit of solubility of test item under test conditions
Test substance could not be detected in any of the test susbstance preparations with a limit of detection of 1 mg/L.
Key value for chemical safety assessment
Additional information
Isononyl benzoate was tested in growth inhibiton test with single cell green algae Desmodesmus subspicatus under static conditions according to the guidelines EU Method C.3 and OECD 201. 1 g / l isononyl benzoate was stirred for 18 h and undissolved test substance was then removed by filtration. All samples analysed (incl.the stock solution) were below the limit of quantification of the analytical method, i.e. < 1 mg TOC/l. Therefore, no analyses were performed on the test concentrations after 72 h. No negative effects on growth rate were recorded, thus the NOEC growth rate is > = the limit of solubility of test item under test conditions and the EC50 growth rate is > the limit of solubility (limit of detection of TOC analysis = 1 mg/L). In the concentration range tested, the test item had a positive effect on the growth of the algae.
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.
