Additional information
Conclusion on classification
Degradation:
Not readily biodegradable (OECD 301F)
Bioaccumulation:
No potential for bioaccumulation (log Pow of 1.77 at 23 °C at pH 4, log Pow of -0.80 at 23 °C at pH 7 and a log Pow of -1.81 at 23 °C at pH 9).
Aquatic acute toxicity:
- For fish: 96 h LC50 (Cyprinodon variegatus) >106 mg/L (measured, OECD 203)
- For invertebrates: 48 h EC50 (Daphnia magna, immobilization) >102 mg/L (measured, OECD 202)
- For algae: 72 h ErC50 (Pseudokirchneriella subcapitata) >99.7 mg/L (measured, OECD 201)
Aquatic chronic toxicity:
- For fish: 35 d NOEC (Pimephales promelas) 4.67 mg/L (measured, OECD 210)
- For invertebrates: 21 d NOEC (Daphnia magna, immobilization) 57.2 mg/L (measured, OECD 211)
- For algae: 96 h NOErC (Pseudokirchneriella subcapitata)≥99.7 mg/L (measured, OECD 201)
- For plants other than algae: 7 d NOEC (Lemna gibba) 51.1 mg/L (measured, OECD 221)
CLP:
Based on the data above, the substance is not readily biodegradable and has a low potential for bioaccumulation. No acute or chronic effect concentrations <1 mg/L were determined. Therefore, the substance is not to be classified and labelled according to the consolidated version of Regulation (EC) No 1272/2008 and further amendments (ATPs).
M-factor for acute aquatic toxicity: none
M-factor for chronic aquatic toxicity: none
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
