CAS number: 355-93-1
The adsorption/desorption screening study does not need to be
conducted because the substance has a low octanol water partition
coefficient and the adsorption potential of this substance is related to
this parameter. Also, the physicochemical properties of the substance
indicate that it can be expected to have a low potential for
adsorption. The regression method of Güsten and Sabljic (1995) has
predicted the log Koc value to be 2.60 (i.e., Koc = 394).
According to ECHA (2017), substances with log Koc greater than 4
are generally regarded as highly adsorptive and likely to distribute in
sediment and soil. As the predicted Log Koc is less than 4, it is
unlikely that OFPMA will distribute in sediment and soil.
