Conclusion on classification

Short-term toxicity results for Daphnia and algae are available for the substance. The 48h-EC50 for Daphnia magna was 5.43 mg/L. The 72h-ErC50 and 72h-ErC10 for algae are 21.7 mg/L and 11.4 mg/L, respectively.

 

Short-term (acute) aquatic hazard

Since the acute EC50 values are > 1 mg/L, the substance does not need to be classified according to the CLP Regulation.

 

Long-term (chronic) aquatic hazard

The only available chronic value is the 72h-ErC10 for algae. The chronic classification has to be determined based on this chronic value according to Table 4.1.0, (b) (ii) (as the substance is readily biodegradable) and based on the available EC50 value for Daphnia and environmental fate data according to Table 4.1.0, (b) (iii). The most stringent outcome is leading:

- As the chronic value is > 1 mg/L and the substance is readily degradable, it does not need to be classified based on this available chronic value.

- As the substance has a log Kow of => 4 (i.e. 4.2) and the EC50 value for the other trophic level is >1 but <= 10 mg/L, the substance needs to be classified as Chronic Cat. 2 based on this EC50 value.

 

It is therefore concluded that the substance needs to be classified as Chronic Cat. 2 (H411) according to the CLP Regulation.

GHS

As the 48h-EC50 for Daphnia magna is >1 but <= 10 mg/L, the substance additionally needs to be classified as Acute Cat. 2 (H401) according to GHS.
