Surface tension
Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- Experiment start and end date - 08 June 1999; Study completion date - 11 June 1999.
- 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)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- OECD harmonised ring method
- Specific details on test material used for the study:
- The test article had the following physico-chemical properties:
Name: 40574/B
Batch no: WP 23/PP
Expiry date: 08 February 2006
Storage: At room temperature about 20 °C - Surface tension:
- 70.2 mN/m
- Temp.:
- 20.2 °C
- Conc.:
- 1 000 mg/L
- Conclusions:
- The surface tension of FAT 40574/B was determined to be 70.02 nm at 20.2 °C
- Executive summary:
The determination of the surface tension of an aqueous solution of FAT 40'574/B 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. The determination of the surface tension was accomplished by means of a tensiometer, using the ring method. The force which was required to withdraw a horizontally suspended ring from the surface of the solution is measured. In conclusion, the surface tension of FAT 40'574/B in water (at a concentration of about 0.1 %) was determined to be 70.2 mN/m at 20.2 °C. Based on the criteria as outlined in the OECD Guideline, FAT 40574/B should not be regarded as a surface active substance.
