Specific details on test material used for the study:
Commercial name: Dimetol (as reported in the report):
Chemical nature: 2,6-dimethylheptan-2-ol
Molecular weight: 144.2 g/mol
CAS number: 13254-34-7
Batch: PE00090447
Purity: 99.6 %
Expiry date: 28 May 2016
Key result
Surface tension:
37.4 mN/m
Temp.:
20 °C
Conc.:
90 other: % of saturation concentration
Remarks on result:
other: According to this, the test substance is considered to be surface active.
Conclusions:
The OECD harmonized ring method was applied for the determination of the surface tension of Dimetol.
The surface tension of a test solution at 90% of the test substance saturation solubility in water and at 20°C was 37.4 mN/m. According to this, the test substance is considered to be surface active.
