Surface tension
Administrative data

Description of key information
The surface tension of test substance was: s = 70.2 mN/m (at a concentration of about 0.1%).
Key value for chemical safety assessment
- Surface tension:
- 70.2
- in mN/m at 20°C and concentration in mg/L:
- 1 000
Additional information
The purpose of this study was to determine the surface tension of aqueous solutions of test item DL-Panthenol.
The determination of the surface tension was accomplished by means of a tensiometer, using the ring method. The force which was required to withdraw a horizontally suspended ring from the surface of the solution is measured.
The surface tension of test substance was: s = 70.2 mN/m (at a concentration of about 0.1%).
Based on the criteria as outlined in the EEC Guideline and on the results of this study, DL-Panthenol has to be considered as a not surface active 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.
