Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Link to relevant study record(s)
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2021-02-02 (study initiation) to 2021-02-25 (experimental completion)
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.3 (Relative Density)
- Version / remarks:
- European Commission Regulation (EC) No. 440/2008
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- Version / remarks:
- 2012
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- oscillating densitimeter
- Dynamic viscosity of test material:
- The two measurement results, which correspond well, and also the visual appearance of the test item indicated that the viscosity of the test item was low enough for determination by means of an oscillating densitometer.

- Density:
- 1.28 other: unitless
- Temp.:
- 20 °C
- Remarks on result:
- other: Based on two replicate measurements yielding identical results
- Type:
- density
- Density:
- 1.28 g/cm³

- Remarks on result:
- other: Based on two replicate measurements yielding identical results
- Conclusions:
- Relative Density (D20/4; OECD 109; A.3) = 1.28
- Executive summary:
The relative density (D20/4) was determined compliant with GLP according to OECD TG 109 (2012) and EU method A.3 with the oscillating densitometer at 20 °C.
Two replicate determinations yielded identical results: density (20 °C) = 1.2837 g/cm^3.
The relative density (D20/4) of MAT-144 at 20 °C (compared to water at 4 °C) was determined to be 1.28.
Reference
Two tests were performed at 20 °C. The results are summarised in Table 1.
Table 1: Results of the two tests
Measurement | Density rP20 / g / cm3 |
1 | 1.2837 |
2 | 1.2837 |
Mean | 1.28 |
Mean density rP20 for the two tests: 1.28 g/cm3
The results were within the accuracy range of the test method ( ± 0.01 g/cm³).
The two measurement results, which correspond well, and also the visual appearance of the test item indicated that the viscosity of the test item was low enough for determination by means of an oscillating densitometer.
Description of key information
Relative Density (D20/4; OECD 109; A.3) = 1.28
Key value for chemical safety assessment
- Relative density at 20C:
- 1.28
Additional information
The relative density (D20/4) was determined compliant with GLP according to OECD TG 109 (2012) and EU method A.3 with the oscillating densitometer at 20 °C.
Two replicate determinations yielded identical results: density (20 °C) = 1.2837 g/cm^3.
The relative density (D20/4) of MAT-144 at 20 °C (compared to water at 4 °C) was determined to be 1.28.
