Abstract
The invention provides novel humic acid derivatives obtained by reacting humic acid-containing materials with a noval amide mixture comprising a polyamide and an amido-amine containing one free amino group per molecule. The novel amide mixture is obtained by reacting under amidation conditions a fatty acid containing 16 to 30 carbon atoms with an amine mixture comprising aminoethylethanolamine (AEEA) and one or more polyethylenepolyamines (PEPA) containing 3 or more amino groups per molecule, wherein the weight ratio of AEEA/PEPA is in the range from about 0.25/1 to about 3/1, and wherein the amount of fatty acid is less than the amount required to amidate all of the amino groups and greater than the amount required to amidate all but one amino group per molecule.
