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:
- 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)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- GLP compliance:

- Specific details on test material used for the study:
- Substance identity: Javanol
Batch: 9000308048
Purity: 89.1% (sum of the 2 peaks)
Appereance: Liquid
Storage: Refrigerator (approx. 4°C)
Safety precautions: Routine hygienic procedures are sufficient to assure personnel health and safety - Key result
- Surface tension:
- 41.4 mN/m
- Temp.:
- 20 °C
- Conc.:
- 90 other: % of saturation concentration
- Conclusions:
- The surface tension of Javanol in water (90% of saturation concentration) was determined to be 41.4 mN/m at 20.0 ± 0.5 °C .
Based on the criteria as outlined in the OECD Guideline, Javanol should be regarded as a surface active substance. - Executive summary:
The determination of the surface tension of an aqueous solution of JAVANOL 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 calibration factor was determined to be 1.0325 for double distilled water (table 1). The data are part of RCC's instruments files and a copy is given in the raw data of the present project.
In conclusion, the surface tension of Javanol in water (90% of saturation concentration) was determined to be 41.4 mN/m at 20.0 ± 0.5 °C .
Based on the criteria as outlined in the OECD Guideline, Javanol should be regarded as a surface active substance.
