Executive summary:

A study was performed to determine some physicochemical properties of the test item, DNAN. The methods followed are amongst those described in Commission Regulation (EC) No. 440/2008 and the OECD Guidelines for the Testing of Chemicals. The physicochemical properties which have been determined in this study are detailed below, together with the result obtained for each test.

Key value for chemical safety assessment

Relative density at 20C:
1.53

Additional information

Relative density determination was conducted as a package of physicochemical testing on DNAN (Envigo CRS Limited, NC15WS, 2018). The study was performed according to EC Method A.3 and OECD Method 109 and in compliance with GLP. The relative density of DNAN was determined relative to purified water using a pyknometer at 20°C. Light distillate of petroleum was employed as the displacement liquid.

The relative density (D20,4 ) of DNAN was found to be 1.53.
