Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

For classification purposes Ecotoxicity, Biodegradability and Bioconcentration have to be considered according the CLP regulation ((EC) No 1272/2008). 


 


Ecotoxicity dataset:


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 toand suspended matter a factor of 10 should be applied to the L(E)C50to correct for the lower ecotoxicity observed.


 


Acute Fish: LC50 = 0.148 mg/L (OECD 203)


Acute Daphnia: EC50 = 0.179 mg/L / factor of 10 --> 0.018 mg/L (OECD 202)


Chronic Daphnia: EC10 = 0.032 mg/L / factor of 10 --> 0.003 mg/L (OECD 211)


Algae: ErC10 = 0.080 mg/L / factor of 10 --> 0.008 mg/L (OECD 201)


ErC50 = 0.150 mg/L / factor of 10 --> 0.015 mg/L (OECD 201)


 


Biodegradability


Based on the available studies on biodegradation, the substances are estimated to be readily biodegradable. The 10-days-window criterion does not need to be evaluated for the cationic surfactants under consideration as they are UVCB substances.


 


Bioconcentration Factor


Despite the fact that the log Kow was measured for Amines, N-C16-22-alkyltrimethylenedi-applying the most appropriate method according to the REACH guidance i.e. the slow stirring method (OECD 123), there is unfortunately no reliable relationship between the measured log Kow and BCF for this type of substances. The calculated BCF value indicates that Amines, N-C16-22-alkyltrimethylenedi- have a low bioaccumulation potential.

Conclusion on classification

According the CLP regulation ((EC) No 1272/2008) the substance is classified for the aquatic environment:


Acute aquatic hazard Category 1 (H400) with M Factor of 10


Chronic aquatic hazard Category 1 (H410) with M Factor of 1
