Additional information

Overall, it was noted that the LogKow values predicted for the four IPOX constituents are very closed, ranging from 0.35 to 0.55. The LogKow prediction for the UVCB substance IPOX EH 2240 was computed as a weighted mean among the four predictions for IPOX constituents A, B, C and D; the weights were defined by the different percentages of the constituents in the UVCB composition. Thus, for the UVCB substance IPOX EH 2240 it was derived a representative LogKow prediction equal to 0.43
