Table: Degradation rates

Degradation rate in water:

Predicted hydrolysis half-life approximately 630 h at 20-25°C and pH 7. No significant biodegradation.

Degradation rate in sediment:

OECD 308 study ongoing. This endpoint will be updated when the result of the study is available.

Degradation rate in soil:

Michigan Londo soil, half-lives (closed tubes) 3.7 d at 32% RH and at 22°C to 106.6 d at 100% RH and at 22°C (estimated to be 56 days when corrected for amount of L4 predicted to be in headspace at this RH) (read-across)

In exposure modelling (EUSES 2.1.2) a half-life value of 10 days at 20°C will be used.

Degradation rate in air:

Half-life for reaction with hydroxyl radicals in air: 10.7 days (calculated).
