- Conclusions:
- The density of the substance is determined to be 0.8059 g/cm3 at 20 °C. The relative density at 20 °C is determined to be 0.8074 and at 4 °C 0.8060.
- Executive summary:
Density and relative density of CAS number 7396-58-9 have been measured according to OECD guideline 109. Measurements showed in test conditions a density of 0.8059g/cm3 at 20 °C, a relative density of 0.8074 at 20°C and a relative density of 0.8060 at 4°C. The study was performed according to OECD guidelines but without GLP compliance. Therefore this study is considered as reliable with restrictions.

Description of key information
No data is available for the substance itself. The value has been read across from structurally similar substances (C10 alkyl chain with CAS no. 7396-58-9 and C16-18 alkyl chain with CAS no. 1227096-04-9). The relative density of these structurally similar substances have been measured to be 0.807 at 20 °C for the C10 alkyl chain and 0.787 at 70 °C for the C16-18 alkyl chain. The conclusion is that the substance registered (C12-18 alkyl chain) has a relative density of ca. 0.80 at 20 °C.
