Applicant's summary and conclusion
- Conclusions:
- The water solubility of TETRAHYDRO CITRAL was determined to be: 24.4 mg/L (20 °C, pH 4.3)
- Executive summary:
The water solubility of TETRAHYDRO CITRAL (batch: SC00019145) was determined according to OECD guideline 105 (1995) and Council Regulation (EC) No. 260/2014, Method A.6 from 2017-08-28 to 2017-09-01 at Noack Laboratorien, 31157 Sarstedt, Germany.
The solubility of the test item TETRAHYDRO CITRAL was determined using the flask method at 20 ± 0.5 °C with pre-incubation at 30 ± 0.5 °C.
The analytical method (GC-MS, external standard with internal standard normalisation) for the determination of the test item TETRAHYDRO CITRAL was validated and tested with satisfactory results in regard to linearity, accuracy, precision and specificity.
The water solubility was calculated based on the results of the samples with the two longest incubation times (48 and 72 h).
The water solubility of TETRAHYDRO CITRAL was determined to be: 24.4 mg/L (20 °C, pH 4.3)
