61.3-61.5mN/m at 20C (1g/l)

Key value for chemical safety assessment

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

Additional information

In a guideline study, the substance that was predominantly a mixture of triethylene glycol butyl ether and tetraethylene glycol butyl ether was not found to be surface active. A solution of 1g/l in water produced a surface tension of 61.4mN/m at 20C.
