Description of key information
The surface tension of 5 -methylhexan-2 -one was determined to be 25.5 +/- 1 mN/m at 22 °C.
Key value for chemical safety assessment
- Surface tension:
- 25.5
Additional information
The key value given above has not been determined at 20 °C but at 22 °C. However, this subtle distinction is not expected to have a significant impact and the value was therefore inserted above.
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).
