- density
- Density:
- 0.935 g/cm³
- Temp.:
- 20 °C
- Key result
- Type:
- relative density
- Density:
- 935.5 other: dimensionless
- Temp.:
- 20 °C
- 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.
