- Executive summary:
The density of Benzenesulfonic acid, mono-C10-13-alkyl derivs., compds. with N1,N1-dimethyl-1,3-propanediamine (ACAR 16015)has been determinedto be 1.05 x 103kg/m3at19.0 ± 1.0 ºC, using a gas comparison pycnometer, designed to be compatible with Method A3 Relative Density of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 109 of the OECD Guidelines for Testing of Chemicals, 02 October 2012. The corresponding relative density was calculated to be 1.05.
