Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information
Nickel hydrogencitrate was not surface active.
Key value for chemical safety assessment
Additional information
The surface tension of Nickel hydrogencitrate was determined within a GLP study according to OECD 115.
Since the determined surface tension of Nickel hydrogencitrate is located in the range of 60 ± 2 mN/m, the test item should be regarded as in the borderline area of surface activity.
As the second measurement with a mean value of 61.93 mN/m was performed at 20.0 °C whereas the first one with a mean value of 59.84 mN/m had been made at 20.2 °C, it is stated that the second value should be followed when assessing surface activity of Nickel hydrogencitrate: all measurements at 20.0 and 20.1 °C showed values above 60.0 mN/m. So Nickel hydrogencitrate was classified as not surface active.
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.
