Conclusions:
Under the conditions of the study, the density of the substance was 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 test 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).
