Description of key information
According to “Endpoint specific guidance R.7.1.17.1” the dissociation constant does not have to be conducted for substances that lack ionisable functional groups.
The calculation program SPARC has been used for the prediction and it indicated that the largest component of the substance is not an ionisable compound since nochange in charge was obtained at different pH. The structure of the other components with a concentration > 1% has also been evaluated and do not contain any ionisable functional groups.
Components;
5,5-Bis(hydroxymetyl)-1,3dioxan, 71.2%,
2-(hydroximethyl)-2-(methoxymethoxy) methyl)-1,3- Propanediol 10.8 %,
Pentaerythritol 5.6 %,
2-(5-(hydroxymethyl)-1,3-dioxan-2-yl)propane-1,3-diol 1.6 %
According to “Endpoint specific guidance R.7.1.17.1” the dissociation constant does not have to be conducted for substances that lack ionisable functional groups.
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.
