- Specific details on test material used for the study:
- Batch/Lot Number: 141016
Appearance: Blue powder
Purity: ≥85.5 %
Expiry date: 19 November 2018
Storage condition: Controlled room temperature (15-25 °C, below 70 RH%) - Key result
- Surface tension:
- 64.8 mN/m
- Temp.:
- 20 °C
- Conc.:
- 90 vol%
- Conclusions:
- The surface tension of the aqueous solution of the test item is 64.8 mN/m.
As the surface tension value is above 60 mN/m, the test item is classified as non-surface active substance.
Reference
Note that the tested solution was 90% of the saturation solubility. The achieved concentration was not reported. The loading of the saturated solution was 1000 mg/L (500 mg in 500 mL).
Description of key information
The surface tension of the aqueous solution of the test item is 64.8 mN/m.
Key value for chemical safety assessment
- Surface tension:
- 64.8
- in mN/m at 20°C and concentration in mg/L:
- 900
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.
