Detailed findings for duplicate determinations at both temperatures are provided in the experimental report.

Conclusions:

Fluid liquid. Viscosity decreases with temperature. Potential for Aspiration hazard (< 20.5 mm2/s at 40°C).

Executive summary:

The dynamic viscosity of the test substance was measured according to OECD 114/DIN 53015 guideline, rolling ball method.

Two triplicate determinations were performed at each temperature, and the mean result was retained, respectively 14.8 mPa.s at 20°C, and 6.77 mPa.s at 40°C.

Description of key information

Fluid liquid. Viscosity decreases with temperature.

Key value for chemical safety assessment

Viscosity:

at the temperature of:

20 °C

Additional information

A fully reliable experimental study, conducted according to a recognized OECD/DIN method and under GLP, is available. It is therefore considered as a key study. The result is retained as key data for purpose of CSA.

According to Regulation (EC) No.1272/2008 (CLP) criteria, the derived kinematic viscosity at 40°C is below the threshold value of 20.5 mm²/s, therefore the substance has potential for classification with Aspiration Hazard (to be assessed together with toxicological information).
