Mackay, Level I Fugasitiy modeling was applied to predict the environmental distribution of the parent substance, 2,3 -epoxypropyl neodecanoate and the hydrolized diol form. The Mackay Level I model predicted that approximately 99.7% of 2,3-epoxypropyl neodecanoate would partition into the air compartment. Due to its lower volatility, the hydrolyzed diol form was predicited to partition approximately 74.4% to the water compartment and 25% to the soil compartment.

When using the worst case HPLC Kow (4.4) as the key study value for EPISUITE KOCWIN v2.00, the model yields a Log Koc of 2.404 with the MCI method and 3.203 using the Kow method. The O.E.C.D. test guideline 121 HPLC method experimentally determined Log Koc was 2.16 suggesting that the test substance, 2,3-epoxypropyl neodecanoate has a low potential to adsorp to sediment and soil.
