Conclusion on classification
The parameters for the toxicity (T) criterion are based on long-term chronic toxicity values for aquatic organisms including freshwater fish, invertebrates and algae. The lowest NOEC for the test substance dimethyldioctylammonium chloride (C8DAQ) was experimentally determined to be 0.01 mg/l (algal toxicity study). According to Annex XIII of Regulation (EC) No 1907/2006 and to the Guidance on information requirements and chemical safety assessment Chapter R.11 (PBT Assessment, ECHA (2017)), a substance does not fulfil the criteria for toxicity (T) if the NOEC for chronic testing on fish, daphnids, algae is ≥0.01 mg/L. It is concluded that the test substance does not fulfil the toxicity (T) criterion as laid down in Annex XIII of regulation (EC) No 1907/2006.
The test substance is classified for the environment as acute (short-term) hazard aquatic 1 based on acute toxicity data being below the criterion of 1 mg/l for fish, invertebrates and algae.
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.
