Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
A series of 10 measurements was performed to determine the surface tension of the pure test item . One further serie of 10 measurements was performed for verification on the same sample. The surface tension for the respective series of measurements were 64.27 and 64.99 mN/m. No significant changes and thus no significant dependence on time and temperature were observed. The surface tension of the negative control lay within the accepted range. The surface tension of the test item is 64.27 mN/m. As all measured values were higher than 60 mN/m, the reaction mass of DIPE and 2-methylpent-2-ene was classified as not surface active.
Key value for chemical safety assessment
- Surface tension:
- 64.27
- in mN/m at 20°C and concentration in mg/L:
- 1 000
Additional information
The surface tension of an aqueous solution of reaction mass of DIPE and 2-methylpent-2-ene was determined according to OECD 115 resp. EU A.5 guidelines under GLP. The surface tension was measured to be 64.27 ± 0.09 mN/m
at 20°C. One measurement was performed for verification . No significant changes and thus no significant dependence on time were observed.As all measured values were higher than 60 mN/m, the reaction mass of DIPE and 2-methylpent-2-ene was classified as not surface active.
The surface tension of the negative control lay within the accepted range.
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.
