Description of key information
The test substance C10-DMA is miscible with n-octanol at every ratio.
Key value for chemical safety assessment
- Solubility in organic solvents at 20°C:
- 778.3 g/L
Additional information
Solubility in n-octanol
Solubility in n-octanol was determined for C10-DMA and further members of the DMA category at ambient temperature (20-21 °C). C10-DMA was completely miscible with n-octanol, as was the case for the other DMAs tested. Accordingly, as the limit value, the respective density of the DMA was given as the solubility in n-octanol.
As supporting information, n-octanol solubility of the protonated form of C10-DMA (C10-DMA hydrochloride) as well as for other DMA hydrochlorides was determined. As could be expected, n-octanol solubility of the respective hydrochlorides is pronouncedly lower than neutral amine solubility. Full details are provided in the respective endpoint study records.
Solubility of DMAs and DMA hydrochlorides in n-octanol
| C10-DMA | C12-DMA | C14-DMA | C16-DMA | C18-DMA |
Octanol solubility* (g/L) – Amine | 778.3 | 784.6 | 793.0 | 800.9 | 806.0 |
Octanol solubility (g/L) – Hydrochloride | 159 | 114 | 89 | 60 | 22 |
* Completely miscible in n-octanol; value based on density of the substance
