Description of key information
No toxicity of the category members of the Long Chain Alcohol Esters to aquatic algae up to the limit of water solubility.
Key value for chemical safety assessment
Additional information
One study investigated the effects of the Long Chain Alcohol Esters towards algae. The effects of the analogue substance (2-ethylhexyl oleate, CAS: 26399-02-0) to the freshwater algae Scenedesmus subspicatus were investigated in a study by Rieche (1995). The study was performed according to the EU-method C.3 considering the VCI concept draft for the acute testing of poorly water soluble substances. Testing with a nominal concentration of 100 mg/L without the removal of insoluble particles resulted in a mean inhibition of algal growth of 75.1%. No effects were observed after the removal of the insoluble particles. It can be assumed that these particles inhibited the algal growth due to physical effects. Thus, no effects of the read-across substance below the limit of water solubility were observed, which resulted in an EC50 (72 h) of > 100 mg/L based on the growth rate. Considering the analogue approach it can be concluded, that the category members of the Long Chain Alcohol Esters will not produce toxic effects to aquatic algae and cyanobacteria.
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.
