After shaking, the test sample was clear and no undissolved test item was observed. It was concluded that the water solubility of N-ethylcaprolactam at 20°C was > 1 x 103 g/L.

The pH of the aqueous sample was 11.0.

Description of key information

> 1000 g/L at 20 °C and pH 11.0 (preliminary test, OECD 105)

Key value for chemical safety assessment
