experimental study
Adequacy of study:
key study
Study period:
2009-11-12
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Determination has been run accordingly to standardized method but without GLP compliance.
Qualifier:
according to
Guideline:
OECD Guideline 115 (Surface Tension of Aqueous Solutions)
Deviations:
no
GLP compliance:
no
Other quality assurance:
ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
Type of method:
OECD harmonised ring method
Surface tension:
29 mN/m
Temp.:
23 °C
Conc.:
1 g/L

The CMC is determined to 73 mg/L at pH 7. Also, the surface tension at 1 g/L has been determined to 29 mN/m.

Conclusions:
The CMC is determined to 73 mg/L at pH 7. Also, the surface tension at 1 g/L has been determined to 29 mN/m.
