Description of key information

No study has been performed on tetrairon tris(pyrophosphate) for the endpoint 'surface tension'. An adaptation from the standard testing regime is justified on the following basis:
Based on the structure of tetrairon tris(pyrophosphate), the substance is not expected to present any surface activity. Therefore, and in accordance with Annex VII , section 7.6, column 2 of Regulation (EC) No. 1907/2006 (REACH) further testing for this endpoint is not scientifically justified.
