Reference
The surface tension of an aqueous solution of Silicic acid Aluminium Magnesium Sodium Salt was determined as 72.22 +/- 0.07 mN/m at 20.0 °C.
One measurement was performed for verification (after 98 minutes). No significant changes and thus no significant depend-
ence on time was observed.
As these values were higher than 60 mN/m, Silicic acid Aluminium Magnesium Sodium Salt was classified as not surface active.
The surface tension of the negative control lay within the accepted range.
The aluminium concentration of the 90 % saturated test solution was determined by measurement via ICP-OES with 31.74 µg/L.
Description of key information
Silicic acid Aluminium Magnesium Sodium Salt was classified as not surface active.
Key value for chemical safety assessment
- Surface tension:
- 72.22
Additional information
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.
