Description of key information

72h EL50 (growth rate) 0.18 mg/L, 72h NOELR (growth rate) 0.11 mg/L (Pseudokirchnerella subcapitata); OECD 201, 2011; Vryenhoef H., 2018.

48h EL50 0.41 mg/L (CL: 0.35 - 0.48 mg/L); Daphnia magna; OECD 202, 2004; Vryenhoef, H., 2018.

Based on the current aquatic data set presented above, the Log Kow of 0.3 - 6.5, the BCF (< 500 L/kg wwt.) and the ready biodegradability result (ready biodegradable), under Regulation (EC) 1272/2008, the test item would be classified as follows:

Aquatic Acute Cat. 1

Aquatic Chronic Cat. 3

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)


Chronic toxicity data:


Algae 72h EL10 (growth rate): 0.11 mg/L (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.
