- Conc.:
- 1 000 mg/L
Applicant's summary and conclusion
- Conclusions:
- The surface tension of a solution containing 1 g Sodium-Sucroseoctasulfat in 1 litre water was determined as 75.1 mN/m. The test substance shows a surface tension nearly at the value of pure water, so that the test substance will be regarded to be not surface active at a concentration of 1 g/L.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
