- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)

- Specific details on test material used for the study:
- - Name of test material (as cited in study report): PURASAL S
- Appearance: colourless liquid
- Lot/batch No.: 1208001453
- Expiry date: 13 August 2014
- Storage condition: at room temperature - Key result
- Surface tension:
- 71.8 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1.07 g/L
- Conclusions:
- The surface tension of an aqeous test solution of Sodium (S)-lactate at a concentration of 1.07 g/L at 20 °C was 71.8 mN/m.
- Executive summary:
In a GLP study conducted according to OECD 115 and EU Method A.5, the OECD harmonized ring method was used for the determination of the surface tension of Sodium (S)-lactate. The surface tension of a test solution at a concentration of 1.07 g/L was 71.8 mN/m at 20.0 °C. According to this, the test substance is considered not to be surface active (< 60 mN/m).
Reference
The measured surface tension was multiplied by the calibration factor (0.9992), resulting in a corrected surface tension of 71.8 mN/m.
Description of key information
In a GLP study conducted according to OECD 115 and EU Method A.5, the OECD harmonized ring method was used for the determination of the surface tension of Sodium (S)-lactate. The surface tension of a test solution at a concentration of 1.07 g/L was 71.8 mN/m at 20.0 °C. According to this, the test substance is considered not to be surface active (< 60 mN/m).
Key value for chemical safety assessment
- Surface tension:
- 71.8
- in mN/m at 20°C and concentration in mg/L:
- 1 070
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.
