Results and discussion
Water solubility
- Key result
- Water solubility:
- ca. 3.2 mg/L
- Conc. based on:
- test mat. (dissolved fraction)
- Incubation duration:
- ca. 1 d
- Temp.:
- 20 °C
- pH:
- ca. 7
- Details on results:
- The result 3.2 mg/L for the water solubility of sample 2704905_002 is approx. a magnitude lower than the precalculated solubility for pure decanoic acid with 47.9 mg/L. The most probable reason is the disproportion between water and sample phase in the stored four individual flasks (see page 4). The upper organic layer might be much more attractive for the decanoic acid than the water phase.
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.
