Additional information
Conclusion on classification
The environmental classification of C12-18 AAAO is currently not harmonised according to the CLP Regulation (EC) 1272/2008.
Acute toxicity data is available for the three trophic levels (fish, invertebrates, and algae). The lowest valid effect concentration for freshwater aquatic organisms is 0.68 mg/L (96h-LC50 for fish). Based on the available acute data, the substance should be classified for acute toxicity (Aquatic Acute 1, M=1).
Chronic toxicity data is available for invertebrates and algae. The lowest valid effect concentration is 0.303 mg/L (72h-NOErC for algae). The substance is readily biodegradable; its log Kow is < 4. Based on this available data, the substance should be classified for chronic toxicity (Aquatic Chronic 3).
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.
