Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
OECD Guideline 115 (Surface Tension of Aqueous Solutions)
GLP compliance:
yes
Type of method:
OECD harmonised ring method
Key result
Surface tension:
69.7 mN/m
Temp.:
20.8 °C
Conc.:
1 g/L
Conclusions:
The mean surface tension of test item in water has been determined to be 69.7 mN/m at 20.8 ± 0.5 °C. The test item was considered to be surface-active.
Executive summary:

The surface tension of 90 % saturated solutions of test item in water have been determined to be 69.7 mN/m at 20.0 ± 0.5 °C, using a ring method, designed to be compatible with Method A.5 Surface Tension of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 115 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.  The test item was considered to be not surface-active.

Description of key information

The mean surface tension of test item in water has been determined to be 69.7 mN/m at 20.8 ± 0.5 °C.  The test item was considered to be surface-active.

Key value for chemical safety assessment
