Description of key information
No toxic effects up to the limit of water solubility for Scenedesmus subspicatus (Annex of EU guideline 92/69/EWG)
Key value for chemical safety assessment
Additional information
One study is available on the algal toxicity of Fatty acids, C16-18 and C18 unsaturated isobutyl esters (CAS No. 84988-79-4).
This key study conducted with Fatty acids, C16-18 and C18 unsaturated isobutyl esters (CAS No. 84988-79-4) was performed as a limit test according to the EU guideline 92/69/EWG and GLP (Berger, 1995). The test organism Scenedesmus subspicatus was exposed to the test substance in a static system for 72 hours, at the nominal test concentration 100 mg/L. The test was performed with and without separation of undissolved test material. With undissolved test substance present, algal growth was significantly inhibited. However, when the undissolved phase was separated, no effects on growth were observed. The inhibition can be thus regarded as associated physical effects caused by the undissolved material present. It can be concluded that the substance has no toxic effects on test organism up to the limit of water solubility.
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.
