Viscosity

Administrative data

Endpoint:

viscosity

Type of information:

experimental study

Adequacy of study:

key study

Study period:

2002

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

Materials and methods

Principles of method if other than guideline:

Viscosity was taken from the safety data sheets of two manufacturers, Dow and BASF. Information about the testing method was not available.

GLP compliance:

not specified

Type of method:

other:

Test material

Test material information

Constituent 1

Reference substance name:

propylene oxide

IUPAC Name:

propylene oxide

Constituent 2

Reference substance name:

Methyloxirane

EC Number:

200-879-2

EC Name:

Methyloxirane

Cas Number:

75-56-9

IUPAC Name:

2-methyloxirane

Details on test material:

Test material was racemate from both R(+) and S(-) propylene oxide. This endpoint is not measured / determined with enantio-selective sensors.
Therefore the R(+) value is identical to the racemate endpoint.

Applicant's summary and conclusion

Conclusions:

A dynamic viscosity of 0.28 mPas at 25°C was reported as best estimate from a collection of reliable data which has been subject to peer-review and in which the original data sources are traceable. The result is considered to be reliable.
