Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification

Classification related key information

Degradation

·       Biodegradation: readily biodegradable (O2 consumption, OECD 301 C) based on the RA from CAS 109-89-7

 

Bioaccumulation

·       Log Kow: -1.3 (at 20 °C, OECD 117, HPLC method)

 

Aquatic acute toxicity

·       Fish: LC50 (96 h) > 100 mg/L (nominal, OECD 203) based on RA from CAS 109-89-7

·       Aquatic invertebrates: EC50 (48 h) = 56 mg/L (OECD 202) based on RA from CAS 109-89-7

·       Algae: ErC50 (96 h) = 20 mg/L (meas., EPA algal assay as proposed by Chiaudani and Vighi, 1978) based on RA from CAS 109-89-7

 

Aquatic chronic toxicity

·       Aquatic invertebrates: NOEC (21 d) = 4.2 mg/L (meas. TWA, OECD 211) based on RA from CAS 109 -89 -7

·       Algae: ErC0 (96 h) = 2 mg/L (meas., EPA algal assay as proposed by Chiaudani and Vighi, 1978) based on RA from CAS 109-89-7

 

Classification according to CLP

Based on the result of the analogue substance, Diethylammonium chloride (CAS 660-68-4) is considered to be readily biodegradable and has a low potential for bioaccumulation. Acute toxicity data are available for an appropriate read across substance for all three trophic levels and chronic experimental data are available for aquatic invertebrates and algae. The lowest effect values were determined for algae and were > 1 mg/L (ErC50 (96 h) = 20 mg/L and ErC0 (96 h) = 2 mg/L). Therefore the substance is not classified and labeled according to the consolidated version of Regulation (EC) No 1272/2008 and further amendments (ATPs).
