Applicant's summary and conclusion
- Conclusions:
- The water solubility of fully hydrogenated high erucic acid rapeseed oil was estimated to be below the limit of quantification of the analytical method and was determined to be < 6.2 mg/L at 20 ± 2 °C.
- Executive summary:
The water solubility of fully hydrogenated high erucic acid rapeseed oil was determined using the coloumn elution method according to OECD Guideline 105 and EU Method A.6.
The test flasks, containing carrier material loaded with fully hydrogenated high erucic acid rapeseed oil + tetrahydrofuran (which was later removed by rotary evaporator) were stored in darkness for for 3 d until the test was started. the carrier material was later pourd into a coloumn (togeather with the distilled water) which was connected to a pump. In the first experiment the coloumn flow was adjusted to 0.4 mL/min and in asecond and third experiment the flow rate was adjusted to 0.2 and 0.1 mL/min, respectively.
The saturation concentration was estimated using the TOC-method.
The water solubility of fully hydrogenated high erucic acid rapeseed oil at 20 ± 2 °C was estimated to be < 6.2 mg/L.
