Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 according to DSD (Dangerous Substance Directive 67/548/)

Etherdiamines will be classified R50/53 this is based on the following results;

Although Etherdiamine was found to degrade in a prolonged biodegradation test they could not be proved to be readily biodegradable therefore they are classified R 53.

In a test performed in river water the EC50 for algea was found to be 0.42 mg/L, taking into consideration the mitigation factor of 10 which is to be used when using river water test for classification the EC50 will be 0.042 mg/L. The etherdiamine should therefore be classified R50

Classification according to CLP (Classification, Labeling & Packaging Directive 1272/2008/EC)

Based on the corrected EC50 value for algea of 0.042 mg/L the following classification i relevant:

Acute (short-term) aquatic hazard Acute Category 1

The corresponding M-factor is 10 based on the EC50 of 0.042 mg/L (72h algae river water test of 0.42 mg/L corrected with factor of 10)

When chronic toxicity data are available these should be used for classification for chronic aquatic hazard.

Based on the not readily biodgradable property and corrected NOEC value for daphnia of 0.009 mg/L the following chronic classification is relevant:

Chronic(Long-term) aquatic hazard Chronic Category 1

The corresponding M-factor is 10 based on the NOEC of 0.009 mg/L (21d NOEC daphnia river water test of 0.09 mg/L corrected with factor of 10)
