Description of key information

A GLP study according to EU Method C.19 revealed a low  dimensionless organic carbon-water partition coefficient of <18, indicating that the substance FAT 40841/A TE has a very low potential for adsorption.

Key value for chemical safety assessment

Additional information

The adsorption/desorption behaviour of the substance FAT 40841/A TE was tested in accordance with EU Method C.19 and GLP. The test made use of high pressure liquid chromatography and compared the test substance's retention time to that of a set of reference substances. The test item solution was injected three times and the combined reference solution was injected six times. In the available study, the reference items covered the range of log KOC 1.25 to log KOC 5.63. The retention time of both test item peaks was shorter than the reference item (acetanilide) with the lowest KOC (1.25, which is equal to a KOC value of 18). Therefore, the log KOC of the test item is < 1.25, which is equal to a KOC value of < 18. This value indicates that FAT 40841/A TE is very mobile..
