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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Rationale for reliability incl. deficiencies:
- other: The result comes from internal company data
- 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.

- Remarks on result:
- other: The result is the average of 30 results. Each result was generated with a different batch.
- Conclusions:
- The average density of the test item was found to be 0.8666 g/mL.
- 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 density of the test item was found to be 0.8666 g/mL. The result is the average of 30 results. Each result was generated with a different batch.

Description of key information
For this endpoint a weight of evidence approach has been taken. The density reported in the CRC Handbook (1993) is 0.8693 g/mL at 20°C. Additionally, measurements performed at the industrial site are available. The average of 30 measurements, confirms that the density of the test substance is 0.8666 g/mL.
Key value for chemical safety assessment
- Relative density at 20C:
- 0.866
Additional information
The relative density reported here is the average value obtained from the company data.
