Key result

Type:

relative density

Density:

0.935 other: relative density has no dimension

Temp.:

20 °C

Determination 1: 0.935 at 20 °C

Determination 2: 0.934 at 20 °C

Determination 3: 0.935 at 20 °C

Conclusions:

The test substance is less dense than water.

Executive summary:

The relative density of the test substance was measured under GLP according OECD 109 / EU A3 guideline, oscillating densitimeter method.

After suitable calibration using two reference liquids, a sample was measured in triplicate at 20 °C, and the mean value was retained.

The relative density of the test substance has been determined to be 0.935 at 20 °C.

Description of key information

The substance is less dense than water.

Key value for chemical safety assessment

Relative density at 20C:

0.935

Additional information

A fully reliable experimental study, conducted according to a recognized OECD/EC method and under GLP, is available. It is considered as a key study. The result is retained as key data for purpose of CSA.
