Abstract
POLYETHYLENE OXIDE derivatives of fatty amines, fatty amides and fatty acids are available in commercial quantities from the Armour Chemical Division under the trade names Ethomeens. Ethomids and Ethofats. Ethomeens are tertiary amines having one fatty alkyl group and two polyoxyethylene groups substituted on amino nitrogen : Ethomids are polyoxyethylene oxide substituted fatty amides having the general formula : Ethofats are polyoxyethylene oxide esters of fatty acids having the general formula: The Ethomeens, Ethomids and Ethofats are supplied with fatty chains of from 12 to 18 carbon atoms with polyethylene oxide chains of 220, 440, 660 and 2200 molecular weights. GENERAL PROPERTIES The Ethomeens, Ethomids and Ethofats are all surface-active agents. The Ethomeens are predominately non-ionic but exhibit mild cationic properties because they are tertiary amines. This cationic activity is more pronounced in the Ethorneen salts formed by neutralizing Ethomeens with acids. Ethomids and Ethofats are non-ioni...
