Ecotoxicological information

Endpoint summary

Administrative data

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 7.851 mg test material/L (lowest acute E(L)C50)

-         Aquatic algae: 72-h ErL50 was 11.402 mg test material/L

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

The registered substance is a Natural Complex Substance (NCS).

Acute toxicity of the registered substance 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.

Chronic aquatic hazard: category 2. Reasoning: adequate chronic toxicity data are not available, lowest acute E(L)C50 value is between 1 and 10 mg/L, not rapidly degradable substance with Log Kow of at least one constituent > 4
