Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Surface tension
Administrative data
- 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
- the study does not need to be conducted because surface activity is not a desired property of the material
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
The surface tension of a substance is defined as a property of liquids arising from unbalanced molecular cohesive forces at or near the surface, as a result of which the surface tends to contract and has properties resembling those of a stretched elastic membrane. Upon contact with water, lead oxides are susceptible to a low degree to dissolution, yielding dissociated lead cations in aqueous solution which will be subject to subsequent precipitation to inorganic compounds such as hydroxides and carbonates under ambient conditions. Neither the dissolved cationic lead, nor any of the other precipitation products can reasonably be expected to exert any surface active properties, and those properties are also not desired.
In conclusion, in accordance with REACH Annex VII, Section 7.5, Column 2, testing is not required.

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.
