> 64.883 - < 64.98 N/m
Temp.:
21 °C
Conc.:
0 other: as from sample preparation
Conclusions:
The average surface tension of RD14156 was determined to be 64.92 [mN/m].
Executive summary:

A Kruss Processor Tensiometer K100 was used to determine the surface tension of RD14156 using test method guidelines as set forth under OECD 115. For the test, an appropriate amount of RD14156 was dispersed in distilled water and shaken for 120hrs at 30°C to establish solution equilibrium, before equilibrating the solution at 24°C for 24 hrs. The samples were centrifuged at 5000rpm for 15min and the supernatant was passed through a 0.45μm filter before further diluting to 90% of its former concentration with distilled water.

The average surface tension of RD14156 was determined to be 64.92 [mN/m].

Description of key information

A surface tension measurement was carried out using methods as set forth under OECD 115 test guidelines when using a Kruss Processor Tensiometer K100. The average surface tension of RD14156 was determined to be 64.92 [mN/m].

Key value for chemical safety assessment

Surface tension:
64.92
