Endpoint:
surface tension
Type of information:
experimental study
Adequacy of study:
key study
Study period:
16 April 2018 to 23 July 2018
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
OECD Guideline 115 (Surface Tension of Aqueous Solutions)
Version / remarks:
27 July 1995
Deviations:
no
GLP compliance:
yes (incl. certificate)
Other quality assurance:
ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
Surface tension:
64.5 mN/m
Temp.:
20 °C
Conc.:
90 vol%
Remarks on result:
not determinable
Conclusions:
The surface tension of a test solution at 90% of the test item saturation solubility in water and at 20°C was 64.5 mN/m. According to this, the test item is considered not to be surface active.


Executive summary:

In this guideline (OECD 115) study, [conducted with GLP certification], the substance was determined to be not surface active.

Description of key information
