Description of key information
The hydrolysis determination of FAT 40810/A, at different pH values was based on the OECD Guideline No. 111, "Hydrolysis as a Function of pH"; adopted May 12, 1981 and on the EEC Directive 92/69, Section C.7, "Abiotic Degradation: Hydrolysis as a Function of pH", L383 A, December 1992. The results of pH 4.0, showed no significant degradation of the test item at 50 °C. The degradation of the test item was less than 10 % after 5 days. According to the EEC Directive 92/69, Section C.7 it can be concluded, that the estimated half-life time is higher than one year under representative environmental conditions (25 °C). Therefore, the test item was considered to be hydrolytically stable at pH 4.0, and no further testing was necessary. The results of pH 7.0 and pH 9.0 showed significant degradation of the test item at 50 °C. The degradation of the test item was more than 50 % after 2.4 hours. According to the EEC Directive 92/69, Section C.7 it can be concluded, that the estimated half-life time is shorter than one day under representative environmental conditions (25 °C). Therefore, the test item was considered to be hydrolytically unstable at pH 7.0 and pH 9.0, and no further testing was necessary.
Additional information
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.
