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
