- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 105 (Water Solubility)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.6 (Water Solubility)
- Deviations:
- no

- Type of method:
- flask method
- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material: SOAP012-2
- Purity: Minimum 95%
- Expiration date of the lot/batch: 01 November 2022
STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: Ambient - Water solubility:
- 0.24 g/L
- Conc. based on:
- test mat.
- Incubation duration:
- 72 h
- Temp.:
- 20 °C
- pH:
- >= 8.8 - <= 9.3
- Details on results:
- The detector calibration was found to be linear over the range of 140 to 700 mg/L in hexane with a correlation coefficient of 1.0000.
The water solubility was determined to be 0.24 ± 0.03 g/L. - Conclusions:
- The water solubility was determined to be 0.24 ± 0.03 g/L.
- Executive summary:
Water solubility of fatty acids lanolin lithium salts was tested according to OECD TG 105 using a flask method (Dunning 2018). The test solutions were analysed by gas chromatography following 72 hours shaking in a water bath at 30 +- 0.5°C. The water solubility of the test item was determined to be 0.24 ± 0.03 g/L at 20°C.
The study is GLP-compliant and was conducted according to the standard guideline, therefore is considered reliable without restrictions and suitable as a key study for this endpoint.
