Alkanolamides are the condensation products of Fatty Acids with primary or secondary Alkanolamines to yield, among other products, compounds of the structure: where RCO is a fatty acid radical; where X represents the radical -CHR'CH2OH, in which R' may be H or lower alkyl; and where Y may be H (in the case of primary alkanolamines) or an alkyl group, alkanol group, or the same as X. Alkoxylated Amides are closely related to alkanolamides and may be viewed as ethoxylation products of the alkanolamides. The condensation reaction usually yields some amine soaps, i.e., Soaps, as well as amine esters, i.e., Esters, between the fatty acid and the alcoholic group(s) of the starting alkanolamine. Finally, the commercial alkanolamides may contain ester amides, in which the alcohol group(s) of the alkanolamide depicted in the above structure is esterified with the fatty acid. Some commonly-used alkanolamines in this synthesis include diethanolamine (DEA), monoethanolamine (MEA), and monoisopropanolamine (MIPA). The condensation reaction may be carried out with free fatty acids or with all types of esters of the fatty acids, such as Fats and Oils, and particularly methyl esters. The reaction conditions and the raw material sources determine the blend of materials in the end product and the nature of other by-products. Alkanolamides are used as surfactants and occasionally as emulsifiers. In shampoos they are employed to boost foam and to enhance viscosity. |
