Conclusions:
Based on the results of the read across study, the density of the substance is considered 0.9355 g/cm3 (i.e., equivalent to 935.5 kg/m3) at 20 ± 0.1ºC.
Executive summary:

A study was conducted to determine the density of the read across substance, Coco TMAC (99.6% active) using the pycnometer method, according to OECD 109 and EU Method A.3 Guidelines, in compliance with GLP. The density of the substance was 0.9355 g/cm3 (i.e., equivalent to 935.5 kg/m3) at 20 ± 0.1ºC (Bodsch, 2008). Based on the results of the read across study, the density of the test substance is expected to be in similar range.

Description of key information

The relative density of the read across substance, Coco TMAC was determined using the pycnometer method, according to OECD Guideline 109 and EU Method A.3 (Bodsch, 2008).

Key value for chemical safety assessment

Relative density at 20C:
