1,3 -Dimethyl-2 -imidazolidine is an organic liquid with high boiling point and low volatility which solidifies at temperatures below 7.5 °C. It is highly soluble in water and a log Pow close to one indicates that it will be soluble in substances with a wide range of polarity. The substance has no surfactant properties and contains no ionising groups. It is not flammable, explosive or oxidising and presents no particular physical hazards.
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.
