Aquatic invertebrates: no data available
Algae: 72 h, ErC10 (Pseudokirchneriella subcapitata): 5.06 mg/L (nominal)
Classification according to CLP
Acute toxicity data are available for all three trophic levels whereas chronic data are only available for aquatic algae. The substance is considered to be rapidly degradable in the environment but a potential for bioaccumulation cannot be excluded based on the log Kow of 4.4. Fish was found to be the most sensitive species with a LC50 (96 h) of 8.43 mg/L. Thus, the test substance needs to be classified and labeled as “Aquatic Chronic 2” (H411) according to the 7th ATP of Regulation (EC) No 1272/2008 (CLP).
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.
