Endpoint:
viscosity
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2017
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study without detailed documentation
Remarks:
The study was conducted according to a recognised guideline, but no experimental details are provided. The substance is considered to be adequately identified, with purity. Therefore validation applies with restrictions.

Applicant's summary and conclusion

Conclusions:
Viscous liquid. No potential for Aspiration hazard.
Executive summary:

The dynamic viscosity of the test substance was measured according to ISO3219/DIN53019 standards (listed in OECD 114 guideline), with a rotary viscometer. Measurements were recorded every 10°C between 30 and 60°C, and the regression parameters were determined.

The results, derived from the regression have been calculated to be 606 mPa.s at 40°C, and 9345 mPa.s at 20°C.
