Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment
- Log Kow (Log Pow):
- -0.27
- at the temperature of:
- 20 °C
Additional information
The test item is a surfactant product (surface tension = 52.2 mN/m ± 0.3 mN/m) so the shake flask and HPLC methods (E.U A8) couldn’t be used. In this case, the partition coefficient was calculated by the ratio of solubilities of test item in n-octanol and in water, determined with the flask method. The method used for the experimental determination was consistent to A.6: “Water solubility”, May 2008, the OECD Guidelines n° 105: “Water solubility”, adopted July, 27, 1995 and GLP. A deviation form the guidelines not affected the quality of the study was observed. Due to apparatus problem, the temperature was not recorded during the last 24 hours of the main test. It was checked and the value was stable during the first 48 hours
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.
