Applicant's summary and conclusion
- Conclusions:
- The surface tension of 1 wt% BCZN in deionized water at 20.0 °C was determined to be 72.5 mN/m. This value is as expected very close to the value of pure water at 20.0 °C (72.8 mn/N) which is in accordance with the very low solubility of the substance.
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.
