Stability in organic solvents and identity of relevant degradation products
Administrative data
Link to relevant study record(s)
- Endpoint:
- stability in organic solvents and identity of relevant degradation products
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 25th January to 2nd February 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- other: OECD Guideline 105
- Version / remarks:
- n-Octanol was used instead of water
- GLP compliance:
- no
- Test substance stable:
- not determined
- Transformation products:
- not specified
- Conclusions:
- Due to the formation of a gel, the investigation was stopped after the prelimary test, and the n-octanol solubility was approximated to >586 g/L.
- Executive summary:
The solubility of the test item, Imwitor 375, in n-octanol was determined using the OECD test guideline 105, with use of n-octanol instead of water.
Due to the formation of a gel, the investigation was stopped after the prelimary test, and the n-octanol solubility was approximated to >586 g/L.

Results:
| Experiment | n-Octanol (g) | Weighed sample (g) | Result |
| A | 1.64 | 0.1701 | Clear liquid |
| B | 1.64 | 0.2708 | Clear liquid |
| C | 1.64 | 0.7546 | Clear liquid |
| D | 1.64 | 1.4721 | Clear liquid |
| E | 1.64 | 2.6712 | Clear liquid, viscous |
| F | 1.64 | 2.2890 | Clear liquid, viscous |
| G | 1.64 | 2.3204 | Clear gel |
With 2.32 g of test item being mixed into 1.64 g of n-octanol, a clear gel with a total weight of 3.96 g has been formed. This is equivalent to 58.6% w/w of test item in solution/gel.
As the density of the n-octanol will significantly increase with addition of the test item, it can be concluded that n-octanol solubility is about 586 g/L, resulting in a gel.
Due to the fact that the formation of the gel is a continuous process and no discrete point can be identified at which dissolution in n-octanol switches to gelling, the n-octanol solubility can be approximated to >586 g/L at 20 °C.
