Applicant's summary and conclusion

Validity criteria fulfilled:
yes
Remarks:
The EPI (Estimation Programs Interface) Suite™ is a Windows®-based suite of physical/chemical property and environmental fate estimation programs developed by the EPA’s Office of Pollution Prevention Toxics and Syracuse Research Corporation (SRC).
Conclusions:
Due to the estimated Koc = 4.244 L/kg (estimated from Molecular Connectivity Index) and Koc = 2.376 L/kg (estimate from logKOW = -0.21), adsorption of the substance to soil is very low.
Executive summary:

The Koc of the substance was calculated by KOCWIN Program (v2.00).


Due to the estimated Koc = 4.244 L/kg (estimated from Molecular Connectivity Index) and Koc = 2.376 L/kg (estimate from logKOW = -0.21), adsorption of the substance to soil is very low.
