Conclusions:
Using the pycnometer method, a density of 1.241 g/cm3 = 1241 kg/m3 (20°C) was measured. This value is the mean of two independent determinations.
Executive summary:

The density of 1,1 -Dimethylurea was determined according to the method Pycnometer (liquids and solids)” in OECD Guidelines for the Testing of chemicals 109 - “Density of Liquids and Solids”. The density of the test item was calculated based on the following values:

- mass ofthe pycnometer withn-hexanestandard;

- mass of the pycnometer with the test item andn-hexanestandard;

- mass of the test item added in the pycnometer.

Using this method, a density of 1.241 g/cm3= 1241 kg/m3 (20°C) was measured. This value is the mean of two independent determinations.
