Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The harmonised ring method determined the surface tension of DEA acetate to be 73.0 mN/m at 20 °C.
Key value for chemical safety assessment
- Surface tension:
- 73
- in mN/m at 20°C and concentration in mg/L:
- 1 000
Additional information
A reliable OECD Guideline study, performed to GLP, used the harmonised ring method to determine the surface tension of DEA acetate. A 1000 mg/L solution of DEA acetate was tested. The surface tension was determined to be 73.0 mN/m at 20 °C. The test substance was not considered to be surface active (Brekelmans, 2010a).
The surface tension of TEA acetate, and related alkanolamine acetates - read-across (RA) surrogates RA1 and RA2 - was determined to be 73.0 mN/m at 20°C (Brekelmans, 2010b), 72.3 mN/m at 20.3°C (Tognucci, 2000c) and 74 mN/m at 20.5 °C (Schmiedel, 1997c), respectively.
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.
