Conclusion on classification
Classification and labelling acc. to GHS / CLP
- Acute aquatic toxicity: Classification of methyl-10 -undecenoate is "acute aquatic toxicity category 1", since LC-50 fish acute test and EC-50 algae acute test both are < 1.0 mg/L. Shall apply: hazard statement H400 "very toxic to aquatic life", pictogram GHS09 "environment", signal word "warning".
- Chronic aquatic toxicity: Classification of methyl-10 -undecenoate is "chronic aquatic toxicity category 3", since the substance is readily biodegradable and the lowest NOEC is comprised between 0.1 and 1 mg/L. A hazard statement H412 "Harmful to aquatic life with long lasting effects" shall apply.
Classification and labelling acc. to 67/548/EEC:
- Acute aquatic toxicity: Classification of methyl-10 -undecenoate is "dangerous for the environment, N; R50", since LC-50 fish acute test and EC-50 acute Daphnia test both are < 1.0 mg/l. it applies R50 "very toxic to aquatic organisms", pictogram "dangerous for the environment", code letter "N".
- Chronic aquatic toxicity: Classification of methyl-10 -undecenoate is "dangerous for the environment, N; R50 -53", since LC-50 fish acute test and EC-50 acute algae test both are < 1.0 mg/l plus the substance has a log Kow superior to 3. It applies R50 -53 "Very toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment", pictogram "dangerous for the environment", code letter "N".
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
