- Type of method:
- pycnometer method
- Type:
- relative density
- Density:
- 1.06 other: dimensionless
- Temp.:
- 20 °C
- Type:
- density
- Density:
- 1.06 g/cm³
- Temp.:
- 20 °C
- Conclusions:
- The density of partially unsaturated TEA-Esterquat was determined to be 1.059 g/cm³ at 20°C and the relative density (20/4) was determined to be 1.059 using a density of water at 4°C (0.999972 g/cm³).
- Executive summary:
The density and the relative density were determined using OECD Guideline 109 and EU-Method A.3 (air comparison pycnometer method). The density of partially unsaturated TEA-Esterquat was determined to be 1.059 g/cm³ at 20°C and the relative density (20/4) was determined to be 1.059 using a density of water at 4°C (0.999972 g/cm³).
