EC number: 688-124-7 | CAS number: 152261-43-3
Water solubility
Administrative data
- Endpoint:
- water solubility
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is hydrolytically unstable at pH 4, 7 and 9 (half-life less than 12 hours)

Results and discussion
Applicant's summary and conclusion
- Conclusions:
- In accordance with REACH Annex VII, Section 7.7, this study does not need to be conducted if the substance is hydrolytically unstable.
As shown in GLP study 19-04258-2 {OECD 111, Hydrolysis as a function of pH) the test item Ethanol, 2,2'oxybis-, reaction products with 3-(triethoxysi/yl)-1-propanamine is hydrolytically unstable at pH 4, 7, and 9 with half-life periods <= 30 min.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
