Additional information

A study was conducted in accordance with OECD Guideline 114 using a rotational viscosimeter, to measure the dynamic viscosity of (+)-alpha pinene at 20°C and at constant shear rate of 583 .1 s-1. In these conditions, the dynamic viscosity was determined to be 1.99 ± 0.02 mPa.s.

This result is supported by closed values from secondary literature and studies on (-)-alpha pinene and alpha pinene.
