Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
