Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

EC number: 475-900-3 | CAS number: -
Density
Administrative data
Link to relevant study record(s)
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 30 May - 28 June 2005
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Remarks:
- The study was conducted according to an internationally recognised method, and under GLP. However, the test item identification is incomplete (unspecified cis-trans isomery, therefore identified under the generic CAS 17129-06-5). Therefore validation applies with restrictions.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.3 (Relative Density)
- Version / remarks:
- Directive 92/69/EEC
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- Certificate from 2004-12-22
- Type of method:
- pycnometer method
- Dynamic viscosity of test material:
- No data.
- Type:
- density
- Density:
- 1.215 g/cm³
- Temp.:
- 20 °C
- Key result
- Type:
- relative density
- Density:
- 1.216 other: relative density is dimensionless
- Temp.:
- 20 °C
- Conclusions:
- The substance is much denser than water.
- Executive summary:
The density of the test substance was measured, under GLP, according to EU A.3 guideline, pycnometer method. The pycnometer was calibrated with water. Two runs were performed with the test substance. The average density was calculated as 1.215 g/ml, and converted to relative density, towards water at 4°C, as D20/4=1.2155.
Reference
Determination of the volume of the pycnometer using water:
Temperature (°C) |
Filled (g) |
Empty (g) |
Mass of water (g) |
| 20.0 | 83.01 | 31.19 | 51.81 |
| 20.0 | 83.01 | 31.19 | 51.82 |
The average mass of water is 51.82 g.
The density of water at 20°C is 998.2063 kg/m3 = 0.998063 g/cm3.
The volume of the pycnometer is 51.82 / 0.998063 = 51.92 cm3.
Determination of the density of the test substance
Temperature (°C) |
Filled (g) |
Empty (g) |
Mass of test substance (g) |
| 20.0 | 94.31 | 31.19 | 63.12 |
| 20.0 | 94.26 | 31.19 | 63.07 |
The average mass of test substance is 63.09 g.
The density of the test substance is 63.09 / 51.92 = 1.215 g/ml = 1215 kg/m3.
The relative density D20/4 of the test substance is 1.2155.
Description of key information
The substance is much denser than water.
Key value for chemical safety assessment
- Relative density at 20C:
- 1.216
Additional information
An experimental study, conducted according to EU guideline and GLP, is available. Despite restrictions due to incomplete test item identification (i.e. unspecified cis-trans isomery), it is considered as reliable, and the result is retained as key data.
