Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Reference
Sample Preparation and Analysis. Visual estimation of the water solubility indicated a solubility of 750 g/L therefore a 1g/L solution of the test item in water was prepared for analysis.
The age of the solution and the corresponding surface tension for both runs (after correction for water calibration):
Solution Age (minutes) | Surface Tension Reading (mN/m) |
Run 1 | |
0 | 27.7 |
30 | 27.5 |
60 | 27.6 |
90 | 27.5 |
120 | 27.6 |
Run 2 | |
0 | 28.5 |
30 | 28.2 |
60 | 28.3 |
90 | 28.3 |
120 | 28.4 |
The test material is considered to be surface-active.

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.
