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.
