Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Method A.5 Surface tension, Directive 92/69/EEC, published in OJ No L 383A, December 1992, using the OECD harmonized ring method for the measurement (Part 1.6.4.).
GLP study.
Key value for chemical safety assessment
- Surface tension:
- 66.6
- in mN/m at 20°C and concentration in mg/L:
- 1
Additional information
The surface tension of the test substance was measured.
The test substance was dissolved to the concentration of 1 g/L and surface tension was measured by ring method with Surface tensiometer.
The test substance, Humic acids, sodium salts, at test concentration of 1 g/L shows corrected surface tension of 66.6 mN/m at 20 ºC (± 0.5ºC ).
As the surface tension is higher than 60 mN/m, test substance should not be regarded as a surface-active material.
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.
