Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Link to relevant study record(s)
- 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:
- The water solubility of C.I. Solvent Red was empirically determined to be less than 1.0E-4 g/L at 20.0 °C using the flask method (OECD 105). Furthermore, Quantitative Structure Activity Relationships for various representative structures of C. I. Solvent Red (i.e. varying the number of C12 alkyl groups 1-6) indicated that water solubility ranged from 9.43E-13 to 6.52E-44 mg/L at 25 °C (WSKOW v1.42). Thus, the test material is highly water insoluble, and hydrolysis testing is not technically feasible and is therefore waived.
Reference
Description of key information
Since the water solubility of the test material is so low (i.e. ranging from 9.43E-13 to 6.52E-44 mg/L), hydrolysis testing is not technically feasible and is waived.
Key value for chemical safety assessment
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.
