Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The relative density of the substance is approximately 0.716, based on data from the C12-14 AO analogue.

Key value for chemical safety assessment

Relative density at 20C:

Additional information

The relative density of C12 -18 AO has not been measured directly due to the inability to produce a freeze-dried sample with less than approximately 23 %w/w residual water content. Measured data are available for the C12 -14 AO from a test conducted in accordance with the procedure described in EU Regulation (EC) 440/2008, Annex Part A test A3 under GLP [Younis S (2010)]. The measured density of the substance, 716 kg/m3 at 23 °C, was divided by the relative density of water at 4 °C to derive the relative density of 0.716. It is considered that read across to the C12 -18 amine oxide is valid due to the large overlap in chain length distribution between the two substances.
