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:
- 2nd November, 2016
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- other: OECD TG 105
- Deviations:
- yes
- Remarks:
- n-octanol used instead of water
- GLP compliance:
- no
- Other quality assurance:
- ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
- Specific details on test material used for the study:
- Batch # 7703200
- Medium:
- n-octanol
- Solubility:
- > 2 000 g/L
- Temp.:
- 20 °C
- Test substance stable:
- not determined
- Details on results:
- For raw data see Table 1
- Conclusions:
- The n-octanol solubility of the test item is > 2.0 kg/L, or rather unlimited.
- Executive summary:
The solubility of the test item in n-octanol was determined using OECD TG 105 (shake flask method). Increasing amounts of the test item were added to 1.64 g of n-octanol at room temperature and the mixtures shaken and allowed to stand for 24 hours. The mixture was visually checked for any undissolved parts of the sample. The solubilty of the test item at 20 °C was determined to be equivalent to 71.0 %w/w, or a concentration of > 2 kg/L (i.e. unlimited solubility).
Reference
Table 1: Results of solubility test
Experiment | n-octanol (g) | Weighed sample (g) | Result |
A | 1.64 | 0.1677 | clear liquid |
B | 1.64 | 1.0432 | clear liquid |
C | 1.64 | 4.0100 | clear liquid |
With 4.01 g of test item being mixed into 1.64 g of n-octanol, a clear liquid with a total weight of 5.65 g has been formed. This is equivalent to 71.0 %w/w of test item in solution or a concentration of 2.0 kg/L.
Description of key information
The test item is infinitely miscible with n-octanol.
Key value for chemical safety assessment
- Solubility in organic solvents at 20°C:
- 2 000 g/L
