Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Water solubility
Administrative data
Link to relevant study record(s)
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 105 (Water Solubility)
- GLP compliance:
- yes
- Type of method:
- flask method
- Water solubility:
- ca. 1.2 g/L
- Conc. based on:
- test mat.
- Loading of aqueous phase:
- 10 g/L
- Incubation duration:
- 72 h
- Temp.:
- 20 °C
- pH:
- 6
- Water solubility:
- 0.343 g/L
- Conc. based on:
- test mat.
- Loading of aqueous phase:
- 1 g/L
- Incubation duration:
- 72 h
- Temp.:
- 20 °C
- pH:
- 7.3
- Water solubility:
- ca. 0.085 g/L
- Conc. based on:
- test mat.
- Loading of aqueous phase:
- 0.1 g/L
- Incubation duration:
- 72 h
- Temp.:
- 20 °C
- pH:
- 6.2
- Conclusions:
- The water solubility of the test item at 20.0 ± 0.5 °C has been demonstrated to be loading rate dependent, as shown in the following table:
Nominal Loading Rate (g/L) Concentration (g/L)
0.1 0.0853
1 0.343
10 1.20
As the solubility of the test item was loading rate dependent, a single definitive value was not possible.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
