Additional information
According to the Guidance on the Application of the CLP Criteria (ECHA Reference ECHA-09-G-02-EN), if the acute aquatic toxicity is >10 ≤100 mg/L (96h LC50 (fish) = 19.8 mg/L, 24h EC50 (daphnia) = 75 mg/L, and 72h ErL50 (algae) > 160 mg/L), and the substance is not rapidly degradable though there is a low potential for bioaccumulation (log Kow = -0.26), the substance should be classified as Chronic 3. As a result, the substance meets the criteria for category 3 classification according to Regulation (EC) No 1272/2008, Annex I section 4.1.

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).
