Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
The water solubility of Epoxy half acrylate was determined according to OECD Guideline 105 and EU method A.6 using the flask method, as solubility, measured as DOC (dissolved organic carbon), was higher than 10 mg/L when employing the flask method. Six vessels were prepared, nominal concentrations ranged from 100 - 180 mg/L in order to detect dependency of the solubility on the nominal concentration (which is not unusual for mixtures). The replicates showed poor correspondence: standard deviation of all flasks was 5.87 mg/L, corresponding to a relative standard deviation of 39.7%. The concentration of the test item in water lay in the range of 10.13 and 25.99 mg/L for the nominal concentrations 100 - 180 mg/L. Strong dependency of solubility on the added amount of the test item was observed: plotting DOC against nominal concentration showed a coefficient of determination r² of 0.944. Therefore, the water solubility of the test item cannot be stated as fixed value. No observations arousing doubts concerning the accuracy of the results and the validity of the study were made.
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.
