Reference
Endpoint:
viscosity
Type of information:
experimental study
Adequacy of study:
key study
Study period:
Experimental date: 08 November 2018
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Remarks:
The study was conducted according to an internationally recognised method, and under GLP. The substance is considered to be adequately characterised with isomers composition. Therefore full validation applies.
Reason / purpose for cross-reference:
reference to other study
Qualifier:
according to guideline
Guideline:
OECD Test Guideline 114 (Viscosity of Liquids)
Version / remarks:
02 October 2012
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Remarks:
UK GLP Compliance Monitoring Programme (inspected on 21/08/2018 / issued on 19/11/2018)
Type of method:
capillary viscometer (static)
Specific details on test material used for the study:
Storage conditions: Approximately 4 °C, in the dark, under nitrogen
Temp.:
20°C
Parameter:
kinematic viscosity (in mm²/s)
Value:
7.63
Key result
Temp.:
40°C
Parameter:
kinematic viscosity (in mm²/s)
Value:
4.36

Sample measurements:

Determination Temperature (ºC) Time (s) Viscosity (mm2/s) Mean Viscosity (mm2/s)
A 20.0 ± 0.2 788 7,62 7,63
B 789 7,63
A 40.0 ± 0.2 451 4,36 4,36
B 451 4,36
Conclusions:
At 20°C, the substance is a fluid liquid. Viscosity decreases slightly with temperature.
It is relevant with regard to classification for Aspiration hazard (< 20.5 mm2/s at 40°C).
Executive summary:

The kinematic viscosity of the test item has been determined, under GLP, according to the OECD 114 guideline, capillary method.

Duplicate measurements were performed at 20 and 40°C, and the mean result was retained for each temperature.

The substance was found to have low viscosity, with 7.63 mm2/s at 20°C, and slight decrease to 4.36 mm2/s at 40°C.

Description of key information

At ambient temperature, the substance is a fluid liquid. Viscosity decreases slightly upon warming.

Key value for chemical safety assessment

Viscosity:
7.6 mm²/s (static)
at the temperature of:
20 °C

Additional information

A fully reliable experimental study, following guideline and GLP, is available. It is considered as a key study, and the result is retained for purpose of CSA.
