Description of key information

The OECD harmonized ring method was used for the determination of the surface tension of propylene glycol methyl ether. The surface tension of a test solution at a concentration of 1 g/l in water and at 20 °C was 70.7 mN/m. According to this, propylene glycol methyl ether is considered to be not surface active.

Key value for chemical safety assessment

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