Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Tripropylene glycol undergoes reactions with hydroxyl radicals in the atmosphere. The half life of tripropylene glycol due to this reaction, based on a 12-hr day with an OH radical concentration of 1.5E6 OH/cm3 is 0.19 days. The overall rate constant is 56.28 E-12 cm3/molecule-sec.
Key value for chemical safety assessment
Additional information
The calculated half life of tripropylene glycol is 0.19 days with an OH radical concentration of 1.5E6 OH/cm3 (Aopwin, 2000). No reaction of tripropylene glycol with ozone or other atoms were calculated. Overall, tripropylene glycol is rapidly degraded in the atmosphere.
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.
