Surface tension
Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Data waiving:
- study scientifically not necessary / other information available
- 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

Description of key information
Not applicable.
Key value for chemical safety assessment
Additional information
In accordance with column 2 of REACH Regulation (EC) No 1907/2006, Annex VII, the determination of surface tension (required in section 7.6) only needs to be conducted if based on structure of the substance surface activity can be predicted. Based on the structure of 1,1'-(1,1,2,2-tetramethylethylene)dibenzene, no surface activity can be predicted and consequently no testing is required (Ref.: R.7a: Guidance on information requirements and chemical safety assessment, EU-Document (2012)). In addition, the substance is insoluble in water (water solubility = 0.08 mg/L). Thus, determination of the surface activity is technically not feasible.
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.
