Description of key information
The test substance C12-18-DMA is miscible with n-octanol at every ratio.
Key value for chemical safety assessment
- Solubility in organic solvents at 20°C:
- 795.8 g/L
Additional information
Solubility in n-octanol was determined for C12-18-DMA and further members of the DMA category at ambient temperature (20-21 °C). C12-18-DMA was completely miscible with n-octanol, as was the case for the other DMAs tested. Accordingly, the limit value for n-octanol solubility is the density of the substance.
