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 > 100 mg test material/L

-         Aquatic algae: 72-h ErL50 was > 100 mg test material/L

Based on these results, acute E(L)C50s are 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 (UVCB).

Acute toxicity to aquatic invertebrates (Daphnia magna) and to algae (Pseudokirchneriella subcapitata) have been determined in experimental studies using WAFs and performed under GLP compliance in accordance with OECD 202 and 201 guidelines respectively. Based on preliminary studies, limit tests at a loading rate of 100 mg/L have been performed.

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: not classified. Reasoning: Data do not allow classification because adequate chronic toxicity data are not available and the lowest acute E(L)C50 > 100 mg/L.
