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.
