Results and discussion
Solubility in organic solvents / fat solubility
- Medium:
- other: Fat simulant HB 307
- Solubility:
- >= 0.1 - <= 0.9 other: weight fraction
- Temp.:
- 37 °C
- Test substance stable:
- yes
- Details on results:
- In the investigated concentration range (weight fraction ZK 119 649: 0.1-0.9) no phase separation was observed.
ZK 119 649 and fat simulant HB 307 are therefore imiscible in any ratio.

Applicant's summary and conclusion
- Conclusions:
- In the investigated concentration range (weight fraction ZK 119 64 9: 0.1-0.9) no phase separation was observed.
ZK 119 649 and fat simulant HB 307 are therefore miscible in any ratio. - Executive summary:
The solubility of the test substance in fat was determined at 37 degrees C in accordance with OECD Guideline 116.
In the investigated concentration range (weight fraction ZK 119 64 9: 0.1-0.9) no phase separation was observed.
It is concluded that ZK 119 649 and fat simulant HB 307 are therefore miscible in any ratio.
