Description of key information

Data from four guideline studies -

an individual company's substance may have viscosity results that are above or below the criterion for classification as an aspiration hazard.

Key value for chemical safety assessment

Viscosity:
19.5 mm²/s (static)
at the temperature of:
40 °C

Additional information

Viscosity was determined by capillary method in four guideline studies, with results ranging from 19.5-40.36 mm2/s at 40 degrees C, and 41.45-54.14 mm2/s at 20 degrees C. The key value was the lowest result obtained.
