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
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Remarks:
- Test procedure according to method of Analytical Expert Group ETAD (Ecological and Toxicological Association of Dyes and Organic Pigment Manufacturer)
- Reason / purpose for cross-reference:
- reference to same study
- Reason / purpose for cross-reference:
- reference to same study
- Qualifier:
- according to guideline
- Guideline:
- other: Analytical Expert Group ETAD
- Principles of method if other than guideline:
- Determination of octanol solubility.
The method for the determination and analytical investigation is in agreement with the method that was agreed upon at the Analytical Experts Meeting of ETAD (Basel) on January 12, 2005. - Medium:
- n-octanol
- Solubility:
- 1.89 mg/L
- Temp.:
- 24 °C
- Remarks on result:
- other: The determination of octanol solubility was conducted at ambient temperature (24-25 °C).
- Details on results:
- The value above represents the mean from three determinations (sigma=0.10). See below for indidividual results.
- Endpoint:
- solubility in organic solvents / fat solubility

- Endpoint:
- solubility in organic solvents / fat solubility
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- supporting study
- Justification for type of information:
- In general the n-octanol solubility of organic pigments is within in the range of one to three digit µg/L. The particle size of the test material does not influence this intrinsic property significantly.
- Reason / purpose for cross-reference:
- read-across source
- Medium:
- n-octanol
- Solubility:
- 1.89 mg/L
- Temp.:
- 24 °C
- Remarks on result:
- other: The determination of octanol solubility was conducted at ambient temperature (24-25°C)
