Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The surface tension of a 90 % saturated aqueous solution of Fatty acids, C6-19-branched, zinc salts at 20 °C was determined to be 52.53 mN/m (standard deviation of 0.04 mN/m). Due to the fact that the surface tension is < 60 mN/m, the test item is classified as surface-active substance.
Key value for chemical safety assessment
- Surface tension:
- 52.53
- in mN/m at 20°C and concentration in mg/L:
- 19.8
Additional information
The water solubility was determined to be 22 mg/l (OECD 105, EU A.6).
A 90% saturated solution has a concentration of 22 mg/l * 0.9 = 19.8 mg/l
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.
