Description of key information
| Substance | Result of the water solubility (mg/l) | at a temperature of |
| Linoleic acid | 1.59 | 25°C |
| Oleic acid | 0.0115 | 25°C |
Key value for chemical safety assessment
Additional information
No study was conduted on the extract itself.
The water solubility of the test substance was estimated using the constituents approach.
This final extract is a natural complex substance. It is a mixture of several components, and two of them (oleic acid and linoleic acid) represent about 89% of the UVCB.
Literature provides data for oleic acid and linoleic acid as followed :
- linoleic acid at 60% in the extract : 1.59 mg/l at 25°C.
- oleic acid at at 29 % in the extract : 0.015 mg/l at 25°C.
