- Executive summary:
A study was performed to determine the density of the test item N,N-dimethyl dodec-9-enamide. The method followed was designed to be compliant with the OECD Guideline for Testing of Chemicals No. 109, "Density of Liquids and Solids"(2012) and the Method A.3 of Commission Regulation No. 440/2008, “Relative Density”.
In this method, the density is determined at a specific temperature using a pycnometer.
Density is calculated from the difference in weight between the full and the empty pycnometer and its volume. The pycnometer volume is determined by carrying out the experiment at the selected temperature with the quantity of ultrapure water required to fill the pycnometer.
The density of N,N-dimethyl dodec-9-enamide was determined to be 888.4 kg/m3 at 20.0 +/- 0.1°C (mean value of two independent determinations).
The relative density of N,N-dimethyl dodec-9-enamide was determined to be 0.888.

No additional determination was performed.
Description of key information
The relative density was determined to be 0.888 using a pycnometer in a study according to OECD TG 109.
Key value for chemical safety assessment
- Relative density at 20C:
- 0.888
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
