Endpoint:
viscosity
Type of information:
experimental study planned
Justification for type of information:
Experimental study planned:
Data on viscosity are an information requirement according to REACH Annex IX, section 7.17.
There are neither adaption rules according to column 2 nor are there any further adaptations of the standart testing regime forseen according to ECHA guidance document R.7a.

As such, a test according to OECD 114 is considered to be appropriate.
Qualifier:
according to
Guideline:
OECD Test Guideline 114 (Viscosity of Liquids)

Description of key information

Testing proposal - no experimental data on viscosity available.

Viscosity is given based on QSAR result (US EPA T.E.S.T)

Key value for chemical safety assessment

Viscosity:
1.34 mPa · s (dynamic)
at the temperature of:
25 °C

Additional information

Currently, no experimental data on viscosity are available for the submission substance. Result based on QSAR: 1.34 mPa*s at 25°C (predicted, US EPA T.E.S.T. v. 4.2; consensus model). The consensus model is based on the outcome of 5 different models (average), resulting in a range between 0.91 mPa*s and 2.04 mPa*s.

Experimental study planned (testing proposal):
