- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- (Landesamt für Umwelt-, Wasserwirtschaft und Gewerbeaufsicht, Rheinland-Pfalz)
- Type of method:
- plate method
- Surface tension:
- 72.15 - 72.29 mN/m
- Temp.:
- 20 °C
- Conc.:
- 31.74 µg/L
- Conclusions:
- Silicic acid Aluminium Magnesium Sodium Salt was classified as not surface active.
- Endpoint:
- surface tension
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because based on structure, surface activity is not expected or cannot be predicted
- the study does not need to be conducted because surface activity is not a desired property of the material
Referenceopen allclose all
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 dependence 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 sodium salt is not surface active based on structure.
Also, the read-across substance Silicic acid, Aluminium Magnesium Sodium Salt was classified as not surface active.
Key value for chemical safety assessment
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.
