Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Density
Administrative data
Link to relevant study record(s)
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- weight of evidence
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Qualifier:
- according to guideline
- Guideline:
- other: QC-AM- 0001
- Version / remarks:
- Internal analytical method to determine the relative density
- Principles of method if other than guideline:
- Anton PAAR Oscillating U-tube method: a hollow U-shaped tube is electromagnetically forced into harmonic oscillation. The period of oscillation is dependent on the density of the sample in the tube. Therefore, by measuring the period of oscillation, the density or density related values are automatically calculated.
- GLP compliance:
- no
- Type of method:
- oscillating densitimeter
- Key result
- Type:
- relative density
- Density:
- 0.869 other: compared to water at 4°C
- Temp.:
- 20 °C
- Remarks on result:
- other: The result is the average of 38 results. Each result was generated with a different batch.
- Conclusions:
- The average relative density of the test item was found to be 0.8689.
- Executive summary:
The density is determined in-house using a digital densitometer that operates according to the the Anton PAAR oscillating U-tube method. The average relative density of the test item was found to be 0.8689. The result is the average of 38 results recorded in a period from 09/03/2011 until 25/09/2015.

Description of key information
The relative density of the test item is 0.868.
Key value for chemical safety assessment
- Relative density at 20C:
- 0.868
Additional information
For the relative density, in-house density data is available as well as data from two renowned reference handbooks.
For the in-house determination of the density a digital densitometer is used, which operates according to the principles of the Anton PAAR oscillating U-tube method.
An average relative density was found to be 0.8689. This result is the average of 38 measurments recorded in a period from 09/03/2011 until 25/09/2015.
The results from the two renowned reference handbooks are a density of 0.868 g/mL and a relative density of 0.868.
The information obtained from the renowned handbooks is in line with the relative density found during in-house densitometer experiments. The relative density of the substance is found to be 0.868.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
