Reference
Endpoint:
surface tension
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
Guideline:
OECD Guideline 115 (Surface Tension of Aqueous Solutions)
Qualifier:
according to guideline
Guideline:
EU Method A.5 (Surface Tension)
GLP compliance:
yes (incl. QA statement)
Type of method:
OECD harmonised ring method
Surface tension:
54.2 mN/m
Temp.:
20 °C
Conc.:
1 g/L
Conclusions:
The surface tension of the aqueous solution of the test substance, was determined as: 54.2 mN/m at 20°C.
Executive summary:

The surface tension of two aqueous solutions of the test substance, was determined using the OECD harmonized ring method according to the OECD Guideline 115 (dated 1995-07-27) and European Commission Council Regulation (EC) No 440/2008, Annex, Part A, method A.5.

The solubility of the test item in distilled water is above 1 g/L, (2.4 g/L at 20 °C).

According to the OECD and EEC guideline solutions of 1 g/L were prepared. The concentrations of the two solutions were determined by HPLC analyses (results: 995 mg/L for stocksolution 1 and 972 mg/L for stock solution 2).

The surface tension of the aqueous solution of the test substance, was determined as: 54.2 mN/m at 20°C.
