Conclusions:
Relative Density of N,N'-[(methylimino)bis(trimethylene)]bis(stearamide) was determined to be 0.9797 ± 0.0363.
Executive summary:

Relative Density of N,N'-[(methylimino)bis(trimethylene)]bis(stearamide) was determined according to OECD Guideline 109 (27 July 1995), using the pycnometer method at 20 °C.

Relative Density of N,N'-[(methylimino)bis(trimethylene)]bis(stearamide) was determined to be 0.9797 ± 0.0363 (N = 3, P: 95 %).

Description of key information
