Qualifier:
according to guideline
Guideline:
OECD Guideline 115 (Surface Tension of Aqueous Solutions)
Deviations:
no
Remarks:
The study was conducted according to the guideline in effect at the time of study conduct.
GLP compliance:
yes
Type of method:
OECD harmonised ring method
Key result
Surface tension:
17 mN/m
Temp.:
20 °C
Conc.:
1 g/L
Conclusions:
This study and the conclusions which are drawn from it fulfil the quality criteria (validity, reliability, repeatability).
The surface tension was found to be 17.0 mN/m. As the result was less than 60 mN/m, the test substance was considered to be surface active.
Executive summary:

A study was performed to determine the surface tension of the test item in accordance with OECD guideline 115. The surface tension of a 1 g/L aqueous solution of the test item was found to be 17.0 mN/m. As the result was less than 60 mN/m, the test substance was considered to be surface active.
