Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
The log Kow of partially unsaturated IQAC, DMS quaternised is 4.7 at 22 °C. The log Kow was calculated from experimentally derived solubility in water and in n-octanol.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 4.7
- at the temperature of:
- 22 °C
Additional information
The log Kow of partially unsaturated IQAC, DMS quaternised was calculated from experimentally derived solubility in water and in n-octanol. The log Kow is 4.7 at 22 °C.
The log Kow calculated by EPIWIN should not be used for the assessment, because partially unsaturated IQAC, DMS quaternised is ionic. EPIWIN does not take into account the ionic structure.
The log Kow deduced from the results of the HPLC Method according to EU Method A. is not regarded as valid, since the method is not suitable for surfactants as outlined in OECD Guideline 117 and EU Method A.8.
Deduced from the BCF value of 10.7 (see 4.3), the log Kow should be lower than 4.7. However correlation between log Kow and BCF is not linear for substances with high molecular weight and high log Kow.
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.
