- Surface tension:
- 64.56 mN/m
- Temp.:
- 20 °C
- Conc.:
- 90 other: % saturated aqueous solution
- Remarks on result:
- other: standard deviation: 0.05 mN/m
- Conclusions:
- The surface tension of a 90 % saturated aqueous solution of ZINCUM SW/F was 64.56 mN/m (standard deviation 0.05 mN/m).
Due to the fact that the surface tension is > 60 mN/m, Zincum SW/F is classified as not surface-active substance.
Reference
Due to the fact that the surface tension is > 60mN/m, Zincum SW/F is classified not surface-active.
Description of key information
The surface tension of a 90% saturated aqueous solution at 20 °C is 64.56 mN/m . Fatty acids, C16 -18, zinc salts has no surface-active properties.
Key value for chemical safety assessment
Additional information
The surface tension of a 90 % saturated aqueous solution of Fatty acids, C16 -C18, zinc salts was determined to be 64.56 nM/m (standard deviation 0.05 mN/m). Due to the fact that the surface tension is > 60 mN/m, Fatty acids, C16 -18, zinc salts is classified as not surface-active substance.
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.
