Key value for chemical safety assessment

Additional information

In accordance with Regulation (EC) No 1907/2006, Annex IX, Section 9.2,, Column 2, soil simulation testing does not need to be conducted as the chemical safety assessment according to Annex I indicates that there is no need to investigate further the degradation of the substance and its degradation products. The risk characterization ratios (RCRs) of the chemical safety assessment are below 1, indicating that the risks are acceptable.  In addition, the substance does not have a high potential for adsorption to soil. The log Kow is low (-0.78, meas., see IUCLID Ch. 4.7). The estimated adsorption coefficients for the charged and the uncharged molecule is also low (charged molecule: log Koc = 1.59 at pH 7; uncharged molecule: -0.002 to -0.07; see IUCLID Ch. 5.4.1).  Therefore, it is not considered necessary to conduct a soil simulation test. and no biodegradation studies in soil will be provided.
