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:
- From August 03, 2010 to July 29, 2011
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- Study conducted in compliance with agreed protocols, with no or minor deviations from standard test guidelines and/or minor methodological deficiencies, which do not affect the quality of the relevant results. The study report was conclusive, done to a valid guideline and the study was conducted under GLP conditions.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- OECD harmonised ring method
- Surface tension:
- 56.3 mN/m
- Temp.:
- 19.7 °C
- Conc.:
- 1 g/L
- Conclusions:
- The surface tension of MEXORYL SBU in water (at a concentration of about 1 g/L) was determined to be 56.3 mN/m at 19.7 °C ± 0.1 °C. Based on the criteria as outlined in the EEC Guideline and the results of this study, MEXORYL SBU has to be considered as a surface active substance.
- Executive summary:
- The surface tension of MEXORYL SBU in water (at a concentration of about 1 g/L) was determined to be
56.3mN/mat 19.7 °C ± 0.1 °C.
Based on the criteria as outlined in theGuideline and the results of this study, MEXORYL SBU has to be considered as a surface active substance.

Results and Discussoins
The calibration factorΦbwas determined to be 1.0176 for double distilled water. The data are part of Harlan Laboratories' instruments files and a copy is presented in the raw data of thepresent study.
From the individual measurements for the surface tension of the aqueous test item solution, the mean and the corrected value for the given solution were calculated.
Description of key information
The surface tension of MEXORYL SBU in water (at a concentration of about 1 g/L) was determined to be 56.3 mN/m at 19.7 °C ± 0.1 °C.
Key value for chemical safety assessment
- Surface tension:
- 56.3
- in mN/m at 20°C and concentration in mg/L:
- 1 000
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
