Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The QSAR calculated rate constant for the OH sensitized photodegradation of N1,N1,N4,N4-tetrakis(2-hydroxyethyl)1,4-cyclohexanedicarboxamide is approximately 87.8E-12 cm3/(molecule * s). At 500,000 OH radicals / cm3 (typical for Central Europe), this corresponds to a half-life of 4.4 hours (24 hour-days).

Key value for chemical safety assessment

Half-life in air:
4.4 h
