Results and discussion
Water solubility
- Remarks on result:
- other: The test item is miscible with water at room temperature (T = 23°C) and atl T = 20.0°C ± 0.5°C in any ratio.
Any other information on results incl. tables
Analytical Method:
The test item and water were mixed in three different ratios (1 :9, 1: 1, 9: 1) to cover the range of complete miscibility.
The mixtures were shortly shaken by hand at T = 23"C (see observation) and after that conditioned overnight at 20.0°C ± 0.5°C.
The following mixtures were prepared:
Weight of test item |
Amount of water added |
Ratio | Observation | pH |
1.03 g |
9.00 g |
1:9 |
slightly yellow, clear mixture, homogeneous, comoletely dissolved |
11.3 |
4.98 g |
5.04 g |
1:1 |
yellow, clear mixture, homogeneous, comoletely dissolved |
12.2 |
4.51 g |
0.51 g | 9:1 |
yellow-brown, clear mixture, homogeneous, comoletely dissolved |
12.2 |
| water used | 6.4 | |||
After conditioning overnight at 20.0°C ± O.5°C, no changes were observed.
The test item is miscible with water at room temperature (T = 23°C) and atl T = 20.0°C ± 0.5°C in any ratio.
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.
