Description of key information
The surafce tension of the test susbstance, disodium disilicate (delta-crystalline) powder (1g/L solution) was determined in a single study to be 69.9±0.1 mN/m at 20°C.
Key value for chemical safety assessment
- Surface tension:
- 69.9
- in mN/m at 20°C and concentration in mg/L:
- 1 000
Additional information
The surface tension of an aqueous solution of the test substance disodium disilicate (delta-crystalline) (Lot DEH9001216) was determined in a single study (09-59600) according to OECD Guideline 115. The surface tension was determined by measuring the force on a Pt plate. The obtained results showed that the surface tension of a 1g/L solution of disodium disilicate (delta-crystalline) is 69.9±0.1 mN/m at 20°C.
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.
