- Key result
- Surface tension:
- ca. 69.7 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 000 mg/L
- Conclusions:
- Based on the criteria as outlined in the EEC Guideline, the test substance is a not surface active substance.
- Executive summary:
The determination of the surface tension of an aqueous solution of the test substance was based on the OECD Guideline No. 115: "Surface Tension of Aqueous Solutions" (1995) and on the EEC Directive 92/69, Part A, Methods for the determination of physico-chemical properties, A.5 “Surface tension”, EEC Publication No. L383, December 1992. In conclusion, the surface tension of the test substance in water (at a concentration of about 0.1 %) was determined to be 69.7 mN/m at 20.0 °C. Based on the criteria as outlined in the EEC Guideline, the test substance is a not surface active substance.
