Description of key information
The viscosity of Benzyltoluene was determined according to OECD guideline 114.
Using a rolling ball viscosimeter, a viscosity of
3.618 ± 0.018 mPa * s
at 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 of
2.301 ± 0.003 mPa * s at 40.00 ± 0.02 °C
was measured.
Key value for chemical safety assessment
- Viscosity:
- 3.618 mPa · s (dynamic)
- at the temperature of:
- 20 °C
Additional information
The conversion between dynamic and kinematic viscosity is described as follows:
dynamic viscosity (mPa*s) = kinematic viscosity (mm2/s) x density (g/cm3)
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
or
(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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
