The results obtained at 20°C are given in
the following table "Viscosities of the test item measured at 20°C" :
The 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 2.11 ± 0.01 mPa.s.
is classified for aspiration toxicity Category 1 (may be fatal if
swallowed and enters airways) according to Regulation (EC) No 1272/2008
(CLP) criteria and harmful (R65: may cause lung damage if swallowed)
according to Directive 67/548/EEC.
The dynamic viscosity of (-)-alpha-pinene
was determined to be 2.11 ± 0.01 mPa.s at 20.0 ± 0.1 °C at a constant
shear rate of 583.1 s-1.
The test item was considered to be a
Therefore, (-)-alpha-pinene is classified
for aspiration toxicity Category 1 (may be fatal if swallowed and enters
airways) according to Regulation (EC) No 1272/2008 (CLP) and harmful
(R65: may cause lung damage if swallowed) according to Directive
Key study conducted according to the OECD
The result is scientifically acceptable but
not obtained under GLP. Therefore a reliability of 2 (reliable with
restrictions) is assigned.
The viscosity value is supported by
consistent experimental data obtained with alpha-pinene multiconstituent.
