Table 4 shows the results of the main test for the determination of the partition coefficient.
The values represented in the table are rounded values. The calculation was carried out with the original not rounded values.

The partition coefficient at 20 °C of test item 7-Aminocephalosporanic acid was determined by the shake flask method, according to OECD Test Guideline 107 and EC No. 440/2008 Part A. Method A.8.
log Pow < -3.4
Pow < 0.0004
The log Pow is not -3.4, as one is forced to enter in the field above, but the log Pow is <-3.4.
