Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

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.
