Biodegradation
Readily biodegradable: 96.7% after 28 d (OECD 301 A)
Bioaccumulation
log Pow = -1.08 and -7.81 (EpiSuite v4.11, KOWWIN v1.68 QSAR caculation result for constituent 1 and 2,
no information of temperature and pH available)
Aquatic acute toxicity
Aquatic invertebrates
EC50 (48 h) > 110.82 mg/L (OECD 202, D. magna, mean measured concentrations based on constituent 1)
Algae
ErC50 (72 h): > 92.9 mg/L (OECD 201, P. subcapitata, mean measured concentrations based on active
ingredient)
Aquatic chronic toxicity
Aquatic algae
ErC10 (72 h) = 20.15 mg/L (OECD 201, P. subcapitata, mean measured concentrations based on active
ingredient)
Classification according to CLP
Based on the data above the substance is rapidly degradable and has a low potential for bioaccumulation. The effect concentrations for acute aquatic toxicity are above 1 mg/L for aquatic invertebrates and algae. Valid chronic toxicity data are available for algae only. The chronic effect concentration ErC10 (72 h) for algae was 20.15 mg/L. Based on the available data, the substance is not classified and labelled for environmental hazards, according to the consolidated version of Regulation (EC) No 1272/2008 and further amendments (ATPs).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
