Surface tension
Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Study period:
- August 24 - November 17, 2011
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- Refer chapter 13 for the detailed structural analogue justification.
- Reason / purpose for cross-reference:
- read-across: supporting information
- 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:
- yes (incl. QA statement)
- Type of method:
- ring method
- Surface tension:
- 73.6 mN/m
- Temp.:
- 20 °C
- Remarks on result:
- other: Solution prepared with 90% saturation solubility
- Conclusions:
- The surface tension of a test solution at 90% of the 3,3-DDS saturation solubility in water and at 20°C was 73.6 mN/m. According to this, the test substance is considered not to be surface active. The test substance can consider as not to be surface active.
- Executive summary:
A GLP compliant test was carried out with source substance 3,3 DDS according to OECD Guideline no. 115 and EU method A.5: The surface tension of a test solution at 90% of the test substance saturation solubility in water and at 20°C was 73.6 mN/m. According to this, the test substance is considered not to be surface active. Based on test results, we can consider 3,3-DDS as not to be surface active.

Description of key information
The surface tension of the read across substance (3,3-DDS), at 90% saturated solution in water and 20°C, was 73.6 mN/m. According to this, dapsone is not considered surface active.
Key value for chemical safety assessment
- Surface tension:
- 73.6
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.
