Conclusions:
The surface tension was determined to be 27.7 mN/m at 24.5 ºC and 0.8475 mg/mL of sample concentration.
Executive summary:

A study was conducted to determine the surface tension of the read across substance, C8 -18 and C18 -unsatd. DEA, according to OECD Guideline 115.

The surface tension was determined to be 27.7 mN/m at 24.5 ºC and 0.8475 mg/mL of sample concentration (Carillo, 2009).

Description of key information

The surface tension of the read across substance, C8-18 and C18-unsatd. DEA, was determined according to OECD Guideline 115 (Carillo, 2009)

Key value for chemical safety assessment

Surface tension:
27.7
in mN/m at 20°C and concentration in mg/L:
