Additional information

The stability of sodium 3(2H-benzotriazol-2-yl)-5-sec-butyl-4-hydroxybenzenesulfonate in water was investigated according to OECD guideline 111. The hydrolysis of the test item was investigated at 50 °C and pH 4, 7 and 9 in the preliminary test. At 50°C the hydrolysis of test item was less than 10 % at pH 4, 7 and 9. The test item is thus considered stable at pH 4, 7 and 9 and 50°C with a half-life of more than 1 year at 25 °C and pH 4, 7 and 9.
