Additional information
Some of tests used to define the environmental hasard categories are based on alkylamines read-across performed with natural river water. Due to their intrinsic properties (cationic, surfactants), river water ecotoxicity test deliver reproducible results with limited uncertainty.
As river water has a mitigating effect on ecotoxicity due to sorption of the primary alkylamines to the suspended matter, a factor of 10 should be applied to the data obtained to correct for the lower ecotoxicity observed.
Conclusion on classification
The environmental fate and ecotoxicological properties of the registered salt are equivalent to the properties of Amines, C16-18-alkyl (CAS 90640-32-7). As the effect endpoints were related to only one of the ions, therefore the classification of the salt use the effect concentration multiplied by the molecular weight ratio of the substance (according REACH guidance document R7b v4, June 2017 p 81).
The classification of the registered substance according to CLP regulation 1272/2008 EC is defined by :
Aquatic acute category
96h-LC50 fish was 2.9 mg/L (corrected by a factor 10 due to river water testing, that yields 0.29 mg/L)
48h-EC50 invertebrates was 1,1 mg/L (corrected by a factor 10 due to river water testing, that yields 0.11 mg/L)
72h-ErC50 algae was 0.55 mg/L (corrected by a factor 10 due to river water testing, that yields 0.055 mg/L)
The registered substance is therefore considered Aquatic Acute Category I, H400 M=10.
Aquatic chronic category
Long-term test result for fish is not available.
21d-NOEC for daphnia was 0,034 mg/L (corrected by a factor 10 due to river water testing, that yields 0,0034 mg/L)
72h-EC10 for algae was 0,2 mg/L (corrected by a factor 10 due to river water testing, that yields 0,02 mg/L)
It has to be noted that the registered substance is not biodegradable. Therefore, it is classified Aquatic Chronic Category I, H410 M=10
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).
