Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Solubility in organic solvents / fat solubility
Administrative data
Link to relevant study record(s)
- Endpoint:
- solubility in organic solvents / fat solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2012
- Reliability:
- 1 (reliable without restriction)
- Qualifier:
- according to guideline
- Guideline:
- other: OECD 105
- GLP compliance:
- no
- Medium:
- n-octanol
- Solubility:
- < 1 mg/L
- Temp.:
- 20 °C
- Test substance stable:
- yes
- Executive summary:
In the non-GLP Kllimisch 1 study from Frischmann (2012) the octanol solubility of Aspartic acid, N-(3-carboxy-1-oxo-sulfopropyl)-N-(C16-C18 (even numbered), C18 unsaturated alkyl) tetrasodium salts 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 < 1 mg/L.
This value is considered relevant an reliable for the risk assessment.
Reference
Following results were obtained:
Incubation time [h] |
Weighted sample [mg] |
Measured concentration [mg/L] |
24 |
30.42 |
< 1 |
48 |
30.53 |
<1 |
72 |
30.12 |
<1 |
Hence the octanol solublity of the test item in n-octanol is < 1 mg/L.
The n-Octanol solubility was determined at 20 °C. pH value cannot be indicated, as pH is only defined for aqueous solutions, not for octanol solutions.
Description of key information
octanol solubility (20°C): < 1 mg/L.
Key value for chemical safety assessment
