Description of key information

The OECD harmonized ring method was used for the determination of the surface tension of PURASOLV®EL (ethyl-(S)-lactate). The surface tension of a test solution at a ethyl-(S)-lactate concentration of 1 g/l in water at 20 °C was 70.5 mN/m. The test substance is considered not to be surface active.

Key value for chemical safety assessment

Surface tension:
70.5
in mN/m at 20°C and concentration in mg/L:
1 000
