Surface tension
Administrative data
- Endpoint:
- surface tension
- Data waiving:
- other justification
- Justification for data waiving:
- the study does not need to be conducted because based on structure, surface activity is not expected or cannot be predicted
- the study does not need to be conducted because surface activity is not a desired property of the material

Results and discussion
Any other information on results incl. tables
Due to the substance being a water reactive material the surface tension test cannot be conducted. This is due to the fact that test method EC A5 stipulates that the substance is tested as an aqueous solution. OECD test guideline 115 also uses the same procedure. Furthermore, based on the estimated water solubility, the aforementioned methods state that testing is not required when the water solubility is lower than 1 mg/l.
Applicant's summary and conclusion
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.
