Description of key information

The surface tension of a 90% (21.5 mg/L) saturated solution of Piperonyl butoxide (Purity: 95.71%) was found to be 52.0 mN/m.
As the result was less than 60 mN/m, Piperonyl butoxide was considered to be surface active.

Key value for chemical safety assessment

Surface tension:
52
in mN/m at 20°C and concentration in mg/L:
21.5
