Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- August - October 2013
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: A modern study conducted in compliance with GLP standards and followed OECD Guidelines
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- GLP compliance:
- yes
- Type of method:
- ring method
- Specific details on test material used for the study:
- Identifier: EXP1200078
Appearance: Very dark brown (almost black) viscous liquid
Batch: E00275-350
Sample Expiration Date: end-2013
Purity:100% - Key result
- Surface tension:
- ca. 67.3 other: dynes/cm
- Temp.:
- 20 °C
- Conc.:
- 2.2 mg/L
- Remarks on result:
- other: Concentration based on Total Organic Carbon
- Conclusions:
- The mean surface tension for the test substance at 20.0 ± 0.5ºC was 67.3 ± 0.5 dynes/cm (N = 3, RSD
= 0.77%).
Tyndall effect was observed in the test substance aliquot used in the testing. The test
substance, classified by the Sponsor as a surfactant, may have produced micelles in the aqueous
medium. - Executive summary:
The mean surface tension for EXP1200078 at 20.0 ± 0.5ºC was 67.3 ± 0.5 dynes/cm.
