Conclusion on classification
Tests on acute toxicity of the registered were performed for microorganisms and for three trophic levels of aquatic species: fish, algae and crustacea. All tests were conducted under GLP conditions and are considered as valid.
The substance has also been tested for Ready biodegradability during two GLP studies following the OECD 301F guideline. During these studies, the substance was found to be Readily biodegradable.
Acute hazard classification:
The registered substance would not be classified as acute 1 to aquatic organisms accordance with the classification of the CLP. Reasoning: all E(L)C50 values are > 1 mg/L.
Chronic hazard classification:
The registered substance would not be classified for chronic toxicity to aquatic organisms in accordance with the classification of the CLP. Reasoning: E(L)C50 values are comprised between 10 and 100 mg/L, the substance is readily biodegradable and has a log Kow < 4.
