- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2014
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Test Guideline 114 (Viscosity of Liquids)
- Deviations:
- no

- Type of method:
- rotational viscometer (dynamic)
- Key result
- Temp.:
- 20°C
- Parameter:
- dynamic viscosity (in mPa s)
- Value:
- 5.1
- Temp.:
- 40°C
- Parameter:
- dynamic viscosity (in mPa s)
- Value:
- 3.3
- Conclusions:
- mmt had a viscosity of 5.1 mPas at 20°C and 3.3 mPas at 40°C (showing Newtonian behaviour across the measured shear rate 10 1/s to 311 1/s at 20°C and 10 1/s to 100 1/s at 40°C).
- Executive summary:
The test substance had a viscosity of 5.1 mPa s at 20°C and 3.3 mPa s at 40°C (showing Newtonian behaviour across the measured sheer rate 10 1/s to 311 1/s at 20°C and 10 1/s to 100 1/s at 40°C). The viscosity determination was carried out in accordance with OECD 114 guideline.
Reference
Viscosity at 20°C:
Reading 1: 5.125 mPas (showing newtonian behaviour across the measured sheer rate of 10 1/s to 311 1/s. The final sheer rate results were excluded as it did not show Newtonian behaviour.)
Reading 2: 5.055 mPas 9 (showing Newtonian behaviour behaviour across the measured shear rate of 10 1/s to 311 1/s. The final sheer rate results was excluded as it did not show Newtonian behaviour)
Mean: 5.1 mPas (showing Newtonian behaviour across the measured sheer rate of 10 1/s to 311 1/s.)
Viscosity at 40°C
Reading 1: 3.386 mPas (showing Newtonian behaviour across the measured sheer rate of 10 1/s to 100 1/s.)
Reading 2: 3.303 mPas (showing Newtonian behaviour across the measured sheer rate of 10 1/s to 100 1/s.)
Mean: 3.3 mPas (showing Newtonian behaviour across the measured sheer rate of 10 1/s to 100 1/s.)
Description of key information
The viscosity of mmt is 5.1 mPa s at 20°C and 3.3 mPa -s at 40°C (showing Newtonian behaviour across the measured sheer rate 10 1/s to 311 1/s at 20°C and 10 1/s to 100 1/s at 40°C).
Key value for chemical safety assessment
- Viscosity:
- 3.3 mPa · s (dynamic)
- at the temperature of:
- 20 °C
Additional information
As no reliable human evidence on the aspiration hazard of mmt is available and per the CLP Regulation (EC/1272/2008) the aspiration hazard is based on the kinematic viscosity (dynamic viscosity at 40C in mPa s /density of mmt in g/cm3). The kinematic viscosity is calculated for mmt is 3.7 mm2/s. Per section 3.10.1.6.3, a substance is classified as an aspiration hazard if it is a hydrocarbon and has a kinematic viscosity of 20,5 mm2/s or less, measured at 40C.
Based on CLP specifications the viscosity of mmt would result in a Category 1 Aspiration Classification
