- Key result
- Type:
- relative density
- Density:
- 0.89 other: Relative density is dimensionless
- Temp.:
- 20.2 °C
- Conclusions:
- A relative density of 0.89 at 20°C was determined in a reliable study conducted according to an appropriate test protocol, and in compliance with GLP.
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Qualifier:
- according to guideline
- Guideline:
- other: DIN 51757
- Deviations:
- not specified
- GLP compliance:
- not specified
- Type:
- relative density
- Density:
- 0.89 g/cm³
- Temp.:
- 25 °C
- Conclusions:
- A relative density of 0.89 g/cm³ at 25°C is reported in secondary literature (company product literature). The original reference was not available for review and no further information is available. The reliability of this result is not assignable.

Mass of empty pycnometer (g) | 24.7817 | 23.7390 |
Mass of pycnometer + test item (g) | 51.3986 | 50.3339 |
Mass of test item (g)1) | 26.6169 | 26.5949 |
Volume of pycnometer (cm3)2) | 29.9652 | 29.9431 |
Density (g/cm3)3) | 0.8883 | 0.8882 |
Mean value of density (g/cm3) | 0.8883 | |
1) Calculated from the masses (see above)
2) Known from calibration
3) Calculated from the mass of the test item and the volume of the pycnometer
The relative density D420 = 0.8883 g/cm3/ 0.99997 g/cm3= 0.8883
(density of water at 4 °C is 0.999972 g/cm3)
Description of key information
0.89 at 20.2 °C (OECD 109, pycnometer method)
Key value for chemical safety assessment
- Relative density at 20C:
- 0.89
Additional information
The key study is supported by a measured relative density value of 0.88 ( at 20 °C) determined by oscillating densitometer method according to OECD Guideline 109. A measured value of 0.89 g/cm3 (at 25 °C) was obtained from a secondary source (company data).
