Additional information
The key and the supporting study were performed according to Method 107 of the OECD Guidelines for Testing of Chemical and GLP. A deviation from this method was observed in the key study. Indeed, the shake flask method can't be used for surface active agents. But, with the adjustment of pH at 1, the test item was totally unionized and the surface active properties of the test item disappears so the shake flask method could be used to determined the partition coefficient of this test item.
The key study give an experimental value for Log Pow at 25°C and pH 1. The supporting study confirms the surface active properties of the test item at higher pH than 1.
In the key study, estimations of the partition coefficient on the ionized form of the test item were obtained from KOWWIN v1.68a (Sept 2010) © 2000 U.S. Environmental Protection Agency, by inputting the appropriate sodium salts of the acid, and resulted in logPowvalues of -0.45 and -2.29 for the single and double charged anions respectively.
