Description of key information
EC50 0.1-1 mg/L algae spp. (r-a)
Key value for chemical safety assessment
Additional information
An EC50 value in the range 0.1-1 mg/L has been estimated for the effects of the undecanol, linear and branched on algal growth. The estimate is based on expert judgement, which takes into consideration measured and predicted ecotoxicity values for other trophic levels and the relative susceptibility of algae compared to such trophic levels, in the same substance category. The estimation has been determined as a range due to the uncertainty associated with this kind of prediction.
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.
