Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information
Due to intrinsic properties of amine containing cationic surfactants river water ecotoxicity tests deliver reproducible test results with limited uncertainty. As river water has a mitigating effect on ecotoxicity due to sorption of the amines to and suspended matter a factor of 10 should be applied to the data obtained to correct for the lower ecotoxicity observed.
Conclusion on classification
Classification according to CLP regulation 1272/2008 EC
Aquatic acute category
96h-LC50 fish was 2.3 mg/L
48h-EC50 invertebrates was 0.88 mg/L (corrected by a factor 10 due to river water testing, that yields 0.088 mg/L)
72h-ErC50 algae was 0.44 mg/L (corrected by a factor 10 due to river water testing, that yields 0.044 mg/L)
The registered substance is therefore considered Aquatic Acute Category I, H400 M=10.
Aquatic chronic category
34d-NOEC fish was 5.75 µg/L
21d-NOEC for daphnia was 13 µg/L (corrected by a factor 10 due to river water testing, that yields 1.3 µg/L)
72h-EC10 for algae was 165 µg/L (corrected by a factor 10 due to river water testing, that yields 16.5 µg/L)
The registered substance is therefore considered Aquatic Chronic Category I, H400 M=1.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
