Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

- Qualifier:
- according to guideline
- Guideline:
- other: OECD 105

- Executive summary:
In the non-GLP Kllimisch 1 study from Frischmann (2012) the octanol solubility of Butanedioic acid, sulfo-, 1,4-bis(2-methylpropyl) ester, sodium salt was determined following the method as outlined in the OECD 105. Instead of water, octanol was used. The octanol solubility at 20°C was determined to be 236 mg/L.
This value is considered relevant an reliable for the risk assessment.
Reference
The concentrations of the different test solutions were calculated automatically using the equation of the calibration curve and considering the dilution factor of the test solutions. The results are listed in the following table:
Nominal saturation concentration (g/L) |
Water solubility, Results (g/L) |
1.011 |
0.247 |
3.086 |
0.219 |
4.017 |
0.226 |
5.011 |
0.255 |
Total average concentration over 4 saturation concentrations: 0.236 g/L (RSD 7.2 %). The n-Octanol solubility was determined at 20 °C.
