Additional information

Delta-damascone was determined to be hydrolytically stable under acidic conditions, but to hydrolyse under neutral and basic conditions. At pH 7 and pH 9, respectively, DT50 values of 332 and 41 days were obtained. No tests on phototransformation in water, air and soil are available. The abiotic degradation rate constants used in the assessment of delta-damascone are:

 

Degradation rate constant for hydrolysis

7.38E-04 d-1

Degradation rate constant for photolysis

6.93E-07 d-1

Degradation rate constant in air

0 d-1
