Additional information

Conclusion on classification

According to Regulation (EC) No 1272/2008 (CLP) The substance does not meet the criteria for acute hazard classification for the aquatic environment. The substance does, however, meet the criteria for chronic hazard classification to the environment. Based on the data presented below the substance is class in the hazard category Aquatic Chronic Category 3.

 

Endpoints used for CLP assessment:

 

Acute toxicity data:

 

Fish 96h LC50: > 47 mg/L (OECD 2023: Squance, D., 2019)

Daphnid 48h EC50: 41 mg/L (OECD202: Squance, D., 2019)

Algae 72h EC50 (growth rate): 30 mg/L (OECD 201: Vryenhoef, H., 2019)

 

Chronic toxicity data:

 

Algae 72h EC10 (growth rate): 7.9 mg/L (Vryenhoef, H., 2019)

Environmental fate:

Ready biodegradable: NO (OECD 301A: McLaughlin, S., 2018)

Physicochemical data:

LogKow = 1.89 (OECD 117: Butler, R.E., 2018)
