Description of key information

Based on experimental studies on the registered substance, the key ecotoxicity values are as follow:

-         Aquatic Invertebrates: 48-h EL50 was higher than 100mg test material/L

-         Aquatic algae: 72-h ErL50 was 88.2 mg test material/L(acute E(L)C50 based on growth rate)

Based on these results, the lowest acute E(L)C50 is higher than 1 mg/L.

Therefore, the substance would not be classified as acute 1 to aquatic organisms in accordance with the classification of the CLP.

Additional information

Acute toxicity to aquatic invertebrates (Daphnia magna) and to algae have been determined in experimental studies using WAFs and performed under GLP compliance in accordance with OECD 202 and 201 guidelines respectively.

In the dataset, short-term toxicity to fish was not provided since the tonnage band (1 -10 tonnes/year) does not require that endpoint.

CLP Classification proposal

It is proposed to compare submission substance dataset to CLP environmental criteria laid down in CLP Regulation (including 2nd Adaptation to Technical Progress, Com Reg No 286/2011).

Acute aquatic hazard: not classified. Reasoning: lowest E(L)C50 higher than 1 mg/L.
