Additional information
Conclusion on classification
Classification related key information
Not readily biodegradable: 1% (ThOD) in 28 days (OECD 301 D)
Inherently biodegradable: 84% (ThOD) in 28 days (OECD 302 C)
Log Kow = 2.72
Acute toxicity:
- to fish: LC50 (96h) = 6.7 mg/L for Danio rerio (OECD 203)
- to aquatic invertebrates: EC50 (48h) = 3.0 mg/L for Daphnia magna (OECD 202)
- to algae: ECr50 (72h) = 24 mg/L, for Desmodesmus subspicatus (OECD 201)
Chronic toxicity:
- to fish: NOEC (28d) = 0.15 mg/L for Oncorhynchus mykiss (OECD 204 and 215)
- to aquatic invertebrates: NOEC (21d) = 0.32 mg/L for Daphnia magna (OECD 211)
- to algae: NOEC (72h) = 3.2 mg/L for Desmodesmus subspicatus (OECD 201)
Classification justification according to CLP
Based on the data above, Preventol is considered not rapidly biodegradable. The acute aquatic toxicity EC/LC50 values are in the range from 1 to 10 mg/L for fish and invertebrates. Valid chronic toxicity data are available for fish, invertebrates and algae with the lowest NOEC for fish being 0.15 mg/L. Therefore, Preventol KMX needs to be classified and labelled as environmental hazard Chronic Cat. 2 according to the Regulation (EC) No. 1272/2008 (CLP) and the Regulation (EU) No. 286/2011 (2ndATP).
Classification justification according to DSD
Based on the data above, Preventol is considered to have a low potential for accumulation and is not rapidly degradable. The acute aquatic toxicity EC/LC50 values are in the range from 1 to 10 mg/L for fish and invertebrates. Therefore, Preventol KMX needs to be classified as environmental hazard R51/53 according to the Directive 67/548/EEC.
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.
