Abstract Alkanolamides of this invention are made by condensing a dicarboxylic acid of the following formula: WHEREIN X AND Y ARE INTEGERS FROM 3 TO 9, X AND Y TOGETHER EQUAL 12, Z is a member of the group consisting of hydrogen and COOM1 with one Z of each moiety, and M and M1 are selected from the group consisting of hydrogen, sodium, potassium, lithium, and mixtures thereof, with either monoethanolamine, diethanolamine or isopropanolamine. The bisalkanolamides, dialkanolamides and monoalkanolamides formed at a ratio of 2:1 alkanolamine:carboxyl moiety are excellent detergents and wetting agents. The bisalkanolamides, dialkanolamides and monoalkanolamides of this invention made at a 1:1 ratio of alkanolamine-to-carboxyl moiety are used as foam, wetting and viscosity boosters. When small amounts of these alkanolamides are added to soaps, the formation of insoluble soaps in hard water is hindered and the resulting insoluble soaps are kept dispersed.
The bisalkanolamide according to claim 1 wherein the mole ratio of alkanolamine to dicarboxylic acid is 1:1.
