Conclusion on classification

SUMMARY OF AVAILABLE DATA (key values)

Acute toxicity to aquatic organisms (pelagic):

- Freshwater fish (Danio rerio): 96h-LC50 > 100 mg active ingredients/L (limit test);

- Freshwater crustacean (Daphnia magna): 48h-EC50 > 100 mg active ingredients/L;

- Freswater algae (Raphidocelis subcapitata): 72h-ErC50 > 100 mg active ingredients/L.

Chronic toxicity to aquatic organisms (pelagic):

- Fish: no data;

- Crustaceans: no data;

- Freshwater algae: 72h-ErC10 = 1.13 mg active ingredients/L.

Other ecotoxicity data:

- Aquatic microorganisms (freshwater, activated sludge): 3h-EC50 > 1004 mg active ingredients/L.

Environmental fate:

- Readily biodegradable;

- Low bioaccumulation potential (based on log Kow < 4).

All effective concentration are expressed in active ingredients and are relevant for the REACh-registered substance. According to the CLP criteria for hazard classification, the substance does not have to be classified for acute and chronic environmental hazards.
