According to a Mackay Level I model calculation, the main target compartment for isophorone diamine will be the hydrosphere (99.8 %), followed by sediment and soil (0.08 % each). The calculated Henry’s law constant of 0.000446 Pa m3/mol (HenryWin v3.10) indicates very low volatility of isophorone diamine from surface waters. With a calculated log Koc of 2.97 at pH 7, the sorption potential of isophorone diamine to soil or sediment organic matter is expected to be moderate (Blume scale).
