Link to relevant study record(s)
- Endpoint:
- viscosity
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2001
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:

- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Test Guideline 114 (Viscosity of Liquids)
- Deviations:

- Key result
- Temp.:
- other: 298.15K
- Parameter:
- dynamic viscosity (in mPa s)
- Value:
- 0.846
- Conclusions:
- Under the test conditions, the dynamic viscosity of (S)-(-)-limonene at 298.15 K was determined to be 0.8462 mPa.s.
- Executive summary:
A study was conducted similarly to OECD Guideline 114 to determine the dynamic viscosity of (S)-(-)-limonene using Schott measuring system equipped with capillary viscometers. The kinematic viscosity was calculated from the average of six flow times using equation: ν = k (t – θ). The dynamic viscosity was calculated by the equation: η = ρν (ρ is density).
Under the test conditions, the dynamic viscosity of (S)-(-)-limonene at 298.15 K was determined to be 0.8462 mPa.s.
Reference
Literature data (Brown et al.,1988): dynamic viscosity of (S)-(-)-limonene = 0.846 mPa.s
