Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data
Link to relevant study record(s)
- Endpoint:
- viscosity
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- supporting study
- Justification for type of information:
- L-Limonene is the S-isomer of d-limonene. Therefore, data on l-limonene can be used for extrapolation to d-limonene. See read-across justification document in section 13.
- Reason / purpose for cross-reference:
- read-across source
- Key result
- Temp.:
- other: 298.15K
- Parameter:
- dynamic viscosity (in mPa s)
- Value:
- 0.846
- Conclusions:
- The dynamic viscosity of (-)-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).
The dynamic viscosity of (-)-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
Description of key information
The dynamic viscosity of d-limonene at 25°C is stated at 0.8462 mPa.s.
Key value for chemical safety assessment
- Viscosity:
- 0.846 mPa · s (dynamic)
- at the temperature of:
- 25 °C
Additional information
The viscosity of d-limonene was derived from a read across with l-limonene, one enantiomer of the regsitered substance having the same physico-chemical properties. The reported study is reliable with restrictions (2) having been conducted similarly to OECD 114 guideline with minor deviations.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
