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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Additional information
Releases into the environment are efficiently prevented by technical and organizational measures during production of isophorone diisocyanate, formulation and use of formulations as well as from its use as a monomer for the production of polymers or other downstream products. Releases into the environment may occur accidentally or during professional applications of low concentrated products.
Distribution modelling according to Mackay Level I indicates that the main target compartments will be soil and sediment with approximately 43 % each, followed by water with about 10 %.The calculated Henry’s law constant of 0.941 Pa m3/mol (vapour pressure x molecular weight / water solubility) at 20-23 °C indicates low volatility from aqueous solution. Both Henry’s law constant and adsorption / desorption constant cannot be studied due to rapid hydrolysis of isophorone diisocyanate. Environmental distribution considerations for isophorone diisocyanate are of little relevance because the reaction with water is expected to eliminate the substance from the environment rapidly.
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.
