Additional information

A single study to investigate the potential of the substance to undergo hydrolysis was conducted in accordance with the standardised guidelines OECD 111 and EU Method C.7 under GLP conditions. And awarded a reliability score of 1 in accordance with the criteria for assessing data quality set forth by Klimisch et al. (1997).

The hydrolytic stability of the test material was investigated in a preliminary study for 5 days at pH 5, 7 and 9. The concentration of the sample solution was determined by ion chromatography (IC). As less than 10 percent of hydrolysis was observed after 5 days, the test material is considered to be hydrolytically stable and as such no additional testing was required.

The estimated half-life at 25 °C is greater than 1 year at pH 4, 7 and 9.
