- Type of method:
- ring method
- Surface tension:
- 37.5 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1.117 g/L
- Conclusions:
- The surface tension of MDIPA Esterquat C18 unsatd. at 20°C was determined to be 37.5 mN/m (1.117 g/L).
- Executive summary:
The surface tension of MDIPA Esterquat C18 unsatd. was determined according to OECD Guideline 115 (27 July 1995) and EU Method A.5 (30 May 2008) using the ring tensiometer method. A surface tension of 37.5 mN/m at 20°C was determined at a test item concentration of 1.117 g/L. Based on the results, MDIPA Esterquat C18 unsatd. is considered to be surface-active. The measurement was performed at a concentration exceeding water solubility.
Reference
Little droplets could be observed at the rim of the measuring vessel. The test solution was slightly turbid.
Description of key information
