Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Hydrolysis
Administrative data
- Endpoint:
- hydrolysis
- Data waiving:
- study technically not feasible
- Justification for data waiving:
- the study does not need to be conducted because the substance is highly insoluble in water
- Justification for type of information:
- No determination of water solubility was feasible for the test item. This was due to the test item, representative of the chemical class of anionic surfactants, showing significant surface-active properties in an aqueous environment. When attempting to generate saturated solutions, a colloidal suspension (i.e. containing micelles < 0.2 µm) was formed. As this dispersed, excess, undissolved material could not be satisfactorily removed by either centrifugation of filtration techniques, it was not possible to isolate a genuine saturated aqueous solution of test item suitable for analysis and quantification.
In addition, hydrolysis is not expected to occur, as the metal salts of fatty acids do not contain functional groups that undergo hydrolysis.

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.
