op-TSA is hydrolytically stable at pH 4, 7 and 9 at 50 °C for five days.

Key value for chemical safety assessment

Additional information

one study, valid without restrictions, is available with o-TSA. It is assumed that these results can be used for op-TSA as well. The study is performed according to OECD guideline 111 and shows that o-TSA is hydrolytically stable at all pHs at 50 °C for five days, therefore op-TSA is assumed to be hydrolytically stable as well.
