The viscosity of Benzyltoluene was determined according to OECD guideline 114.Using a rolling ball viscosimeter, a viscosity of 3.618 ± 0.018 mPa * sat 20 °C was measured, this value is the mean of two independent triplicate determinations with their standard deviation. Good correlation of the two determinations was given (relative standard deviation was 0.50 %). All measurements were performed at 20.00 ± 0.04 °C. Additionally a viscosity of2.301 ± 0.003 mPa * s at 40.00 ± 0.02 °Cwas measured.
The conversion between dynamic and kinematic viscosity is
described as follows:
dynamic viscosity (mPa*s) = kinematic viscosity (mm2/s) x density
For Benzyltoluene the kinematic viscosity at 40 °C is 2.303 mm2/s.
A substance is classified in Category 1:
(a) based on reliable and good quality human evidence
(b) if it is a hydrocarbon and has a kinematic viscosity of 20.5
mm2/s or less, measured at 40 °C .
According to these criteria Benzyltoluene has to be classified
into Category 1 for aspiration hazard. No further testing is required.
