Description of key information

The partition coefficient (N-octanol/water) of ITACONIC ACID was determined in three ration of N-octanol/water:1:1,2:1 and 1:2(V/V). The test was carried out with two replicates by previous dissolution of the test substance in N-octanol saturated with water and the mixture prepared as cited above. The flasks were shaken, centrifuged and left to stand to separate the phases. The active ingredient Itaconic Acid was determined in both phases by liquid chromatography(HPLC/UV). The partition coefficient of ITACONIC ACID was tested at  temperature of 20℃.

Additional information

According to the test results (OECD 107), the partition coefficient of ITACONIC ACID expressed as LogKow is -0.301(pH 3.17)at average temperature of 20℃.
