Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification

Benzenediamine, ar-methyl-, polymer with 2-methyloxirane and oxirane shows no acute effects towards aquatic organisms of three trophic levels (algae, crustaceans and fish) up to concentrations of 100 mg/L. Long-term testing in Daphnia on a structural analogue (oTDA-PO) resulted an EC10 > 1. The registration item is neither readily biodegradable (27 % in 28 days), nor inherently biodegradable (42 % in 27 days) and the substance is hydrolytically stable at 50 °C at pH 4, 7 and 9. Benzenediamine, ar-methyl-, polymer with 2-methyloxirane and oxirane has a low potential to bioaccumulate. The information on the substance is reliable and sufficient for classification purposes.


Based on the available information on Benzenediamine, ar-methyl-, polymer with 2-methyloxirane and oxirane, there is no need to classify the registration item for environmental hazards according to Regulation (EC) 1272/2008 on Classification, Labelling and Packaging of Substances and Mixtures.
