Additional information
Conclusion on classification
Classification and labelling according to to DSD:
Justification for classification or non classification
Three acute tests have been performed with fish, daphnia and algae. No relevant effects have been observed.
The substance is not readily biodegradable and has a logPow of 5.4. Therefore, a classification related to risk phrase R53 is required.
Classification and labelling according to to CLP:
Justification for classification or non classification
Three acute tests have been performed with fish, daphnia and algae. No relevant effects have been observed. The lowest NOEC-value from a chronic study is 0.0172 mg/L leading to a classification H410 category chronic 1.
Summary for classification and labelling
DSD: R53 - may cause long-term adverse effects in the aquatic environment
CLP: H410 - Very toxic to aquatic life with long lasting effects.
