- Executive summary:
Neat P-tert-butylstyrene has a surface tension of 32.9 mN/m at 20 0C, rising to 67.6 mN/m when a 0.1% solution in water when measured using EEC A5
Reference
EEC A5 calls for a plot of Surface Tension v Time in order to show any trend in surface tension with time. However, from the results given below, no trend was observed as all the results obtained were randomly scattered around the mean.
Description of key information
The surface tension of neat substance was 32.9 mN/m at 20°C, rising to 67.6 mN/m for a 0.1% solution in water when measured using EEC Method A5.
Key value for chemical safety assessment
- Surface tension:
- 32.9
- in mN/m at 20°C and concentration in mg/L:
- 1 000
Additional information
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.
