Phototransformation in air

Stability of the substance in the atmosphere was calculated using the software AOPWIN (v 1.92). It is predicted that the substance will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals. The half-life for this reaction in air is estimated to be between 4.6 and 13.8 hours, at different test conditions. The most conservative value was selected.

Hydrolysis

In accordance with REACH Regulation 1907/2006, Annex VIII, Column 2 hydrolysis as a function of pH does not need to be determined as the substance is readily biodegradable.

Stability of the substance against hydrolysis was calculated using the computer program HYDROWIN (v 2.00). A base-catalysed second-order hydrolysis rate constant of 0.03486 L/mole-sec was estimated using a structure estimation method. This corresponds to half-lives of 6.3 years at pH 7 and 230.2 days at pH 8.
