- Sample identification : 17.076961.0001
Batch Number:Lot 91602E004 20/06/17
Purity:70% w/w of CAS 7281-04-1 and 30% w/w of CAS 18773-88-1 (stated)

The sample is mixed and homogenized taking care to avoid the introduction of air bubbles. 1,0083g of test sample were accurately weighted and diluted to 100 mL in a volumetric flask with MilliQ water. The solution thus made is drawn using an appropriate pipette sampling it from the centre of the bulk of the solution and directly delivered to the glass cup and immediately analysed. - Key result

- Conclusions:
- The test substance is a surface active substance
- Executive summary:
In an OECD 115 study, mean surface tension is 28.26mM/m. Therefore, the test substance has a value of surface tension lower than 60 mN/m, and is
a surface active substance
Reference
Surface tension (mean, mM/m) : 28.26
Surface tension (SD, %) : 0.95
The test substance has a value of surface tension lower than 60 mN/m
