Results and discussion
Solubility in organic solvents / fat solubility
- Medium:
- n-octanol
- Solubility:
- > 549 g/L
- Temp.:
- 20 °C
- Remarks on result:
- other: With increasing amount of test item (> 549 g/L) a gel is formed.
- Test substance stable:
- yes
Any other information on results incl. tables
Preliminary test:
To 1.64 g of n-octanol, the following aliquots of test item were added:
Experiment |
Weighed sample [g] |
Result |
A |
0.01 |
clear liquid |
B |
0.05 |
clear liquid |
C |
0.2 |
clear liquid |
D |
1.0 |
clear liquid, viscous |
E |
2.0 |
clear gel |
With 2.0 g of test item being mixed into 1.64 g of n-octanol, a clear gel with a total weight of 3.64 g has been formed. This is equivalent to 54.9% (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 549 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 > 549 g/L.
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
