Description of key information
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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
