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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Applicant's summary and conclusion
- Conclusions:
- The substance has, based on QSAR, an extremely low water solubility well below 0.1mg/l, which is consistent with expectation based upon chemical structure. The substance therefore meets the criteria for data waiving and the study is considered not scientifically justified. The hydrophobic nature of the substance and the presence of the mineral oil is, however, likely to lead to micelle formation at the surface of water. It is hypothesised that the ionic sulphonate head will be attracted to water while the hydrophilic tail will tend to the oil, which may have the effect of forming an emulsion which may, in turn, lower the surface tension of the water phase.
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.
