Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

As indicated in the read-across justification, data from Amine oxide can be used for read-across to N,N-Dimethyl-1-octadecanamine-N-oxide (CAS 2571-88-2 / EINECS 219-919-5) mutagenic potential (Ames test). For the Amine Oxides group, considering all genotoxicity data, the conclusion is that there is not a concern for genotoxicity. On the basis of this data, there is no evidence of mutagenicity with or without S9 activation for N,N-Dimethyl-1-octadecanamine-N-oxide.
