Applicant's summary and conclusion
- Conclusions:
- The Surface Tension of Suberic Acid is determined as 64.9 mN/m ± 0.2 mN/m at test temperature (20 ± 0.5 °C).
- Executive summary:
The Surface Tension of Suberic Acid was determined by ring method at 20 ± 0.5 ºC. The solution thus formed was allowed to equilibrate at the test temperature (20 ± 0.5 ºC) using constant temperature water bath.
Three aliquots of the 1% w/v aqueous solution of Suberic Acid in analytical grade water were prepared. The average corrected surface tension value obtained from the three aliquots of the 1% w/v aqueous solution is reported as the surface tension of Suberic Acid.
The corrected surface tension of Suberic Acid is determined as 64.9 mN/m (± S.D. = 0.2) at test temperature (20 ± 0.5 °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.
