Administrative data
Link to relevant study record(s)
- Endpoint:
- viscosity
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- From 29 August 2012 to 02 October 2012
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- The study was conducted according to an internationally recognised method, and under GLP. No deviation was reported. Substance ID is adequately specified with purity and isomers composition. Therefore full validation applies.
- Reason / purpose for cross-reference:
- reference to other study
- Qualifier:
- according to guideline
- Guideline:
- OECD Test Guideline 114 (Viscosity of Liquids)
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- UK GLP Compliance Programme (inspected on 10 July 2012 / signed on 30 Nov. 2012)
- Type of method:
- capillary viscometer (static)
- Specific details on test material used for the study:
- - Storage condition of test material: room temperature, in the dark.
- Temp.:
- 20°C
- Parameter:
- kinematic viscosity (in mm²/s)
- Value:
- 8.37
- Remarks on result:
- other: +/- 0.02 mm2/s
- Temp.:
- 20°C
- Parameter:
- dynamic viscosity (in mPa s)
- Value:
- 7.83
- Temp.:
- 40°C
- Parameter:
- kinematic viscosity (in mm²/s)
- Value:
- 4.54
- Remarks on result:
- other: +/- 0.02 mm2/s
- Temp.:
- 40°C
- Parameter:
- dynamic viscosity (in mPa s)
- Value:
- 4.25
- Conclusions:
- At 20°C, the substance is a fluid liquid. Viscosity decreases slightly with temperature.
- Executive summary:
The kinematic viscosity of the test substance was measured according to the OECD 114 guideline, capillary method.
Duplicate measurements were performed at 20 and 40°C, and the mean result was retained for each temperature. Results were converted to dynamic viscosity from the density.
Reference
The results are shown in the following table:
| Determination | Temperature (ºC) | Time (s) | Viscosity (mm2/s) | Mean Viscosity (mm2/s) | Viscosity (mPa.s) |
| A | 20.0 ± 0.5 | 879 | 8.35 | 8.37 | 7.83 |
| B | 882 | 8.38 | |||
| A | 40.0 ± 0.5 | 477 | 4.53 | 4.54 | 4.25 |
| B | 478 | 4.54 |
Description of key information
At 20°C, the substance is a fluid liquid. Viscosity decreases slightly with temperature.
Key value for chemical safety assessment
- Viscosity:
- 8.37 mm²/s (static)
- at the temperature of:
- 20 °C
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, and the result is retained as key data for purpose of CSA.
