Description of key information

The critical micelle concentration of the test item of CHIMEXANE NV in aqueous solutions was determined to be 7.55 mg/L. 

Key value for chemical safety assessment

Water solubility:
7.55 mg/L
at the temperature of:
20 °C

Additional information

The registered substance exhibits surface active properties which have been confirmed by experimental determination of surface tension. Thus, determination of true water solubility is considered as difficult. An unreliable experimental study on water solubility is available. Two QSAR predictions using Wskowwin and SPARC provide indication of slight solubility of substance main constituents in water. An experimental determination of the critical micelle concentration (CMC) of the registered substance was carried out. The critical micelle concentration was determined by measuring the surface tension of the test item in the concentration range between 0.1 µg/L to 300 µg/L. The critical micelle concentration of the test item of CHIMEXANE NV in aqueous solutions was determined to be 7.55 mg/L.

pH of the solution being not mentioned in the report, the study was considered as reliable with restriction.

This value was considered as the minimum Water Solubility of the Chimexane NV at 20.0°C.
