Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Based on the prediction using AOPWIN v1.93 (EpiSuite 4.11), the OH radicals photodegradation rate of the substance is 1.458584E-10 cm³ molecule-1 s-1, and the related DT50 can then be estimated 0.88 hours (AOPWIN v1.93), or 2.64 hours (EUSES v2.1.2). All in being outside the EUSES boundaries (0.99-1.0E+40 d), this DT50 is a more realistic fate of fragrance substance in air, and thus will be used for the environmental CSA.

Key value for chemical safety assessment

Half-life in air:
2.64 h
Degradation rate constant with OH radicals:
0 cm³ molecule-1 s-1
