Physico/Chemical Properties of DEGDB
Note that certain of the determined physico-chemical properties of DEGDB, specifically boiling point, vapour pressure and water solubility, may be influenced to some extent by the impurities present.
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.
