Description of key information
abiotic degradation hydrolysis is lower than 10% after 5 days at 50°C for the pH 4.0 and pH 7.0, but is significant at pH 9 ( > 10% in 5 days at 50°C in the preliminary test).
Key value for chemical safety assessment
Additional information
One key (Klimisch score=1) hydrolysis study (according to EU method C.7, OECD 111, Annex to Commission Directive 92/69/EEC to fulfil requirements of ltalian Legislative Decree No. 52 dated February 3, 1997 implementing Council Directive 92/32/EEC ) was identified for FEXO-07.

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.
