Data used for CLP conclusion:
Acute toxicity data:
Daphnid 48h EL50: 0.41 mg/L (OECD202: Vryenhoef, H., 2018)
Algae 72h EL50 (growth rate): 0.18 mg/L (OECD 201: Vryenhoef, H., 2018)

Environmental fate:
Ready biodegradable: Yes (OECD 301B: Best, N., 2018)
Additional information
All tests were conducted in accordance with International guidelines and GLP. In all cases the validity criteria were met, therefore the studies can be regarded as valid and reliable. The data is representative of the effects Test item has on respective aquatic endpoints.
