Physicochemical characteristics

The physicochemical characteristics whose order of magnitude is indicated hereafter, influence the risks of transfer of this active substance towards water, and risks it pollution the waters:

Hydrolysis with pH 7: stable,
Solubility: 1 000 000 mg/l,
Coefficient of division carbon organics-water: 112 cm ³ /g. This parameter, noted Koc, represents the potential of retention of this active substance on the Organic matter of the ground. The mobility of the active matter is reduced by its absorption on the particles of the ground.
Lasted of half-life: 10 days. This parameter, noted DT50, represents the potential of degradation this active substance, and its speed of degradation in the ground.
Coefficient of division octanol-water: -1,59. This parameter, noted Log Kow or Log P, measurement the Hydrophily (low values) or the Lipophilia (strong values) of the active substance.
