Additional information
Conclusion on classification
Classification related key information
Biodegradation in water: screening tests: not readily biodegradable
The partition coefficient (n-octanol/water) log Pow is > 3. 78.
Acute toxicity
- to fish: LC50 (96 h) >1000 mg/L
- to aquatic invertebrates: LC50 (48 h) >1000 mg/L for Daphnia
- to aquatic algae: EC50 (96 h) =354.67 mg/L
Chronic toxicity not available
Classification according to CLP
Based on the data above, UV-1084 is considered to be not rapidly degradable. The acute aquatic toxicity L(E)C50 values are >1000 mg/L for fish and aquatic invertebrates and 354.67 mg/L for algae. No chronic data are available. Therefore, according to Regulation (EC) No. 1272/2008 (CLP), no aquatic toxicity classification is taken.
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.
