NITROGENOUS CONDENSATION PRODUCTS

摘要

Nitrogenous compounds are obtained by reacting(a) the amide, imidazoline or mixed amide/imidazoline condensate of an optionally ethylenically unsaturated carboxylic acid or 5 to 26 carbon atoms and an N-aminoethyl C2-C4 alkanolamine the condensate having its hydroxy group optionally oxyalkylated with up to 4 units of a C2-C4 alkylene oxide with (b) either (i) an .alpha.,.beta.-unsaturated dicarboxylic acid of 4 to 5 carbon atoms or a partial ester of such an acid or a salt of such an acid or partial ester or (ii) an .alpha.,.beta.-unsaturated monocarboxylic acid of 3 to 5 carbon atoms or a salt thereof to result in the saturation of the double bond thereby binding the acid residue through an ester linkage and in the case where said reactant (b) is a monocarboxylic acid subsequently reacting said reaction product with a halo alkanoic acid to introduce an -R3COOM group at the tertiary nitrogen of said first reaction product wherein R3 is an alkylene group of 1 to 5 carbon atoms and M is hydrogen or a cation. These compounds are useful as surfactants and detergents and are especially useful in shampoo preparations.
