2,3 -Epoxypropyl neodecanoate was demonstrated by both QSAR modeling and experimental results to have a relatively rapid rate of photodegradation in the atmosphere a half-life of 0.9 - 1.1 days. 2,3 -Epoxypropyl neodecanoate was biodegraded approximately 7 - 11% and is therefore, not readily biodegradable. However, when 2,3 -epoxypropyl neodecanoate was evaluated in an "Inherent Biodegradability: Modified SCAS Test" the level of biodegradation reached 68% +/- 5% over days 22 to 36 of the study. In an O.E.C.D. test guideline no. 302C Modified MITI (II) Test the test substance had a mean percent biodegradation of -1% after 28 days of sludge contact. The weight-of-evidence demonstrated that 2,3 -epoxypropyl neodecanoate does not biodegrade. 2,3 -epoxypropyl neodecanoate does not meet the criteria for PBT. The estimated Log Pow for 2,3 -epoxypropyl neodecanoate of 2.6 suggests a low potential for bioaccumulation. Furthermore, the experimentally determined Log Koc of 2.16 suggest that the test substance has a low potential to adsorp to sediment and soil. Abiotic hydrolysis studies have demonstrated that the test substance has a half-life of 8.8 to 9.9 days over a pH range of 4 to 9 at 25 degrees C. The Mackay Level I Fugasitiy 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.
