Description of key information

1-ETHYL-3-METHYL IMIDAZOLIUM ETHYLSULFATE is hydrolytically stable (halflife time at 25°C> 1 year) in aqueous solutions buffered at pH 4, pH 7 and pH 9 based on analysis of the 1- ETHYL-3-METHYL IMIDAZOLIUM part of the test substance.

Key value for chemical safety assessment

Additional information

The determination of the hydrolysis rate of 1-ETHYL-3-METHYL IMIDAZOLIUM ETHYLSULFATE as a function of pH was based on the EEC-Directive 92/69 EEC, Part C, Methods for the determination of Ecotoxicity, C.7: "Abiotic degradation: Hydrolysis as a function of pH", EEC Publication no. L383, December 1992. 1-ETHYL-3-METHYL IMIDAZOLIUM ETHYLSULFATE is hydrolytically stable (halflife time at 25°C > 1 year) in aqueous solutions buffered at pH 4, pH 7 and pH 9 based on analysis of the 1- ETHYL-3-METHYL IMIDAZOLIUM part of the test substance.
