Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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 hazard classification toward the aquatic environment, in accordance with the criteria set in Regulation (EC) No 1272/2008 (CLP).


The substance meets the criteria for chronic hazard classification toward the aquatic environment, Aquatic Chronic Category 3, in accordance with the criteria set in CLP, as the lowest EC50 is > 10 and < 100 mg/L, the substance is readily biodegradable, experimental log Kow > 4 and a (Q)SAR exists for BCF exists indicting a BCF of < 113 L/kg wet wt. Therefore, as no experimental value has been derived for BCF, classification of Chronic 3 is appropriate. 


 


Endpoints used for hazard assessment:


Fish 96h LC50: 57.1 mg/L (Anon., 2023)


Daphnid 48h EC50: 72.28 mg/L (Delpit, 2023)


Algae 72h EC50 (growth rate):  13.943 mg/L (Delpit, 2023)


Algae 72h EC10 (growth rate):  4.191 mg/L (Delpit, 2023)


 


The following are considered for classification & labelling (CLP (Regulation (EC) No 1272/2008)):


Data used for assessment: Acute algae toxicity


72h EC50 (growth rate): 13.943 mg/L (Delpit, 2023)


72h EC10 (growth rate): 4.191 mg/L (Delpit, 2023)


 


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)
