Description of key information

The surface tension of DPG (1,3-diphenylguanidine) was performed at 23°C as a concentration below 325 mg/l (ca 300 mg/l) using the ring method using an apparatus Lecomte/Nouy.
The surface tension was found equal to 58.8 mN/m

Key value for chemical safety assessment

Surface tension:
58.8
in mN/m at 20°C and concentration in mg/L:
300
