Link to relevant study record(s)
- Endpoint:
- partition coefficient
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- From February 15, 2017 to March 02, 2017
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 107 (Partition Coefficient (n-octanol / water), Shake Flask Method)
- Version / remarks:
- The flask-shaking method was modified to be the stirring method.
- Type of method:
- other: Stirring method
- Partition coefficient type:
- octanol-water
- Analytical method:
- photometric method
- Type:
- log Pow
- Partition coefficient:
- <= -6.103
- Temp.:
- 20 °C
- pH:
- 7
- Conclusions:
- Equivalent or similar to OECD 107 test method, the log Pow of CR SB37 was ≤ -6.103.
- Executive summary:
This test using the procedures outlined in the ECIC Study Plan for 170215-04 and modified OECD 107. Since the solubility of the dye in octanol is very low, the flask-shaking method is not applicable. Based on this, it was modified to use the stirring method. The Pow, calculated as the quotient of the octanol and water solubility, is ≤ 7.891 × 10 -E7. Therefore, it corresponds with a log Pow value of ≤ -6.103.
Reference
The water solubility of CR SB37 was 261.059 g/l and the solubilityof CR SB37 in octanol was 2.06 × 10-4g/l. The Pow, calculated as the quotient of the octanol and water solubility, is ≤ 7.891 × 10-7.
Description of key information
The log Pow of CR SB37 was ≤ -6.103 (Modified OECD TG107).
Key value for chemical safety assessment
- Log Kow (Log Pow):
- -6.103
- at the temperature of:
- 20 °C
Additional information
The flask-shaking method was modified to be the stirring method.
