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:
0.716

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.
