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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Key result
- Type:
- relative density
- Density:
- 0.992 other: relative density is dimensionless
- Temp.:
- 20 °C
- Type:
- density
- Density:
- 0.992 g/cm³
- Temp.:
- 20 °C
- Conclusions:
- The test substance is slightly less dense than water.
- Executive summary:
The density of the test item was determined according to the OECD guideline No. 109 (oscillating densitymeter method), and under GLP.
The determination was made in duplicate, and results were found consistent.
The density of the test item is ρ = 0.992 g/mL at 20 °C or relative density D20/4 = 0.992.
Reference
Accuracy checking
The calibration of the instrument was verified at 20.0°C with cyclohexane as a reference substance just before the determinations. The results were: Cyclohexane: reference value: 0.779 g/ml instrument reading: 0.779 g/ml The results are within the precision of the instrument (± 0.001 g/ml).
Density determination
The results obtained with test item at 20.0°C were:
first sample: ρ = 0.992 g/ml
second sample: ρ = 0.992 g/ml
average (rounded off): ρ = 0.992 g/ml or D204= 0.992
The estimated precision is: ± 0.001 g/ml.
No deviations from guidelines, study plan and standard operating procedures.
Description of key information
Experimental density = 0.992 g/cm3 at 20°C. (OECD 109, GLP)
The substance is slightly less dense than water.
Key value for chemical safety assessment
- Relative density at 20C:
- 0.992
Additional information
A fully reliable experimental study, conducted according to a recognized OECD method and under GLP, is available.
It is considered as a key study; the result is retained as key data for CSA.
