Results and discussion
Water solubility
- Temp.:
- 20 °C
- pH:
- 9.6 - 9.7
- Remarks on result:
- other: miscible in with water in any ratio
Any other information on results incl. tables
| ratio | mtest item | mwater | pH |
| [g] | [ml] | ||
| 1:9 | 1.02 | 9.01 | 9.7 |
| 1:1 | 5.00 | 5.00 | 9.6 |
| 9:1 | 9.98 | 1.01 | 9.6 |
Clear solutions were obtained with colours deepening from colourless (ratio 1:9) to slight yellow (ratio 9: 1).
The test item is miscible with water at T = 23°C and at T = 20°C in any ratio.
The test mixtures were stored for 24 h at 20°C. No change of the appearance at 23°C was observed.
Applicant's summary and conclusion
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.
