Duplicate determinations are within accuracy; therefore the average value is retained.

Relative density D20/4 = 1.08 / 1.00 = 1.08

Conclusions:
The substance is hardly denser than water.
Executive summary:

The density of the test substance was measured under GLP according to OECD 109 / EU A3 guidelines, using oscillating densitometer method.

The determination was carried out in duplicate, and the average result was converted to relative density compared to water at 4°C.

The mean density was measured at 1.08 g/cm3, at 20°C, and the relative density D20/4 is 1.08.

Description of key information

The substance is hardly denser than water.

Key value for chemical safety assessment

Relative density at 20C:
1.08
