Any other information on results incl. tables
In order to calculate the surface tension, the values read on the apparatus were multiplied by the calibration factor Φb. This yields a value, which is only approximate and requires additional correction. The additional correction was made using the factor for correction Fc compiled on the basis of Harkins-Jordan correction (W. D. Harkins, H. F. Jordan, J. Amer. Chem. Soc. 52, 1751, 1930).
The calibration factor Φb was determined to be 1.0195 for double distilled water.
Applicant's summary and conclusion
- Conclusions:
- According to the criteria as mentioned in the directive, substances showing a surface tension lower than 60 mN/m under the conditions of this method, should be regarded as being surface active material. Thus the test item has to be considered as a not surface active substance.
- Executive summary:
The determination of the surface tension of an aqueous solution of the test item was based on the OECD Guideline No. 115: “Surface Tension of Aqueous Solutions” (1995) and on the EEC Directive 92/69, EEC Publication No. L383, December 1992 and the Council Regulation (EC) No. 440/2008, 30 May 2008, Part A, Methods for the determination of physico-chemical properties, A.5 “Surface tension”.
The surface tension of the test item in water (at a concentration of about 1 g/L) was determined to be 72.7 mN/m at 19.5 °C ± 0.1 °C. Based on the criteria as outlined in the EEC Guideline and the results of this study, the test item has to be considered as a not surface active substance.
