Materials and methods
- Principles of method if other than guideline:
- The use of secondary sources of data is acceptable when they are based on a critical evaluation of peer-reviewed data and a consequent selection of a reliable and representative value for the property under investigation. The introduction to the Handbook of Aqueous Solubility Data states that it is an extensive compilation of published data. Each record is evaluated against a five point scheme based on the reporting of temperature, purity of the solute, equilibration time/agitiation, analysis and accuracy and/or precision, allowing the reader to select the most reliable and representative value. Therefore, although the method used is not known, the values presented here are acceptable as they are from a reliable secondary source of phys chem. data.

Results and discussion
Water solubility
- Water solubility:
- 48 - 78 mg/L
- Temp.:
- 25 °C
- pH:
- 7
- Details on results:
- pH not reported so assumed to be 7.
Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information): slightly soluble (0.1-100 mg/L)
The solubility of two branched C6H12 substances is 48-78mg/l at 25°C - Executive summary:
This information is taken from a peer reviewed handbook and so can be considered reliable and suitable for use in the assessment.
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.
