Key result
Temp.:
other: 298.15K
Parameter:
dynamic viscosity (in mPa s)
Value:
0.846

Literature data (Brown et al.,1988): dynamic viscosity of (S)-(-)-limonene = 0.846 mPa.s

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.

Description of key information
