Description of key information
Additional information
Diethanolamine acetate (DEA acetate; EC No: 245 -524 -2) is the manufacturing product of the mixture between diethanolamine and acetic acid. From the physico-chemical data acquired, it can be concluded that DEA acetate and triethanolamine acetate (TEA acetate; EC No: 238-874-2) are similar substances. They both have a low molecular weight, low vapour pressure and high water solubility. Both the density and surface tension values are very close for these two substances and they both decompose before boiling at 125ºC for TEA acetate and 150ºC for DEA acetate (Brekelmans, 2010a, b). In addition, supporting data from structurally-similar alkanolamine acetates, described as read-across (RA) substances RA1 and RA2, are used. The partition coefficient, water solubility and surface tension are similar for all four of these substances.
DEA acetate is a clear colourless viscous liquid (Brekelmans, 2010a) with a glass transition temperature between -64 and -56 °C, and a density of 1.18 g/cm3. The vapour pressure is low (1.68 Pa at 20ºC) and the water solubility is above 1000 g/L (Brekelmans, 2010a). Based on read-across data on TEA acetate (Brekelmans, 2010b), the substance is expected to have a log Pow of less than -1.31 (Brekelmans, 2010a). These properties indicate on a general level that DEA acetate is unlikely to be hazardous for the environment. Other properties of DEA acetate, such as flammability, explosiveness and oxidizing potential, further indicate that the substance is not likely to present a human hazard.
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.
