Solubility in organic solvents / fat solubility
Administrative data
Link to relevant study record(s)
- Endpoint:
- solubility in organic solvents / fat solubility
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Study period:
- 2009-09-04 to 2009-10-08
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with generally accepted scientific standards and described in sufficient detail
- Reason / purpose for cross-reference:
- reference to same study
- Principles of method if other than guideline:
- In a guideline study with the aim to determine the particle size, a preliminary solubility test was conducted to choose a suitable dispersant.
- GLP compliance:
- yes (incl. QA statement)
- Specific details on test material used for the study:
- - Name of test material (as cited in study report): DD Lactide
- Batch no: 0809002497
- Purity: 100%
- Expiration date of the lot/batch: 2009-09-23
- Stability under storage conditions: stable
- Storage: at room temperature in the dark
- Sample density: 1.31 g/cm³ - Medium:
- other: sunflower oil
- Remarks on result:
- other: insoluble, particle disintegration observed under microscope
- Medium:
- other: silicone oil
- Remarks on result:
- other: insoluble, good dispersion
- Medium:
- other: kerosene
- Remarks on result:
- other: insoluble, but poor dispersion
- Medium:
- toluene
- Remarks on result:
- other: soluble
- Conclusions:
- DD-lactide was found to be insoluble in kerosene, silicone oil and sunflower oils, but soluble in toluene.
- Executive summary:
The solubility of the test item in organic solvents was assesed in a GLP non-guideline study. A small quantity of the test item sample was added to 25 mL of different solvents and the mixtures were vortexed for 10 seconds. DD-lactide is insoluble in kerosene, silicone oil and vegetable oils, but soluble in toluene.
