Conclusion on classification

For the purpose of classification and labelling the substance was assessed as a whole. The substance does not meet the criteria for acute or chronic hazard classification toward the aquatic environment, in accordance with the criteria set in Regulation (EC) No 1272/2008 (CLP).

Endpoints used for hazard assessment:

Fish 96h LL50: 100 mg/L (Anon., 2018)

Daphnid 48h EL50: 53.2 mg/L (Kümmich, 2018)

Algae 72h EL50 (growth rate): 10 mg/L (Schuster, 2018)

Algae 72h EL10 (growth rate): 3.24 mg/L (Schuster, 2018)

The following are considered for classification & labelling (GHS Rev7 & CLP (1272/2008)):

Data used for assessment: Acute algae toxicity

72h EL50 (growth rate): 10 mg/L (Schuster, 2018)

72h EL10 (growth rate): 3.24 mg/L (Schuster, 2018)

Substance Rapidly Degradable: yes (28d biodegradation = 92.9 %, Brunswick-Titze, 2017)

Log Kow: <= 5.7 (Baer, 2018)

BCF <= 113 L/kg wet-wt. (Paul, 2018)
