19 Claims

1. Quaternary amidoamine obtained by

forming amidoamines by reacting one or more multifunctional fatty acids comprising from 8 to 26 carbon atoms per acid function of said multifunctional fatty acids with on average from 1.1 to 6.0 acid groups, with one or more amino amines of formula II)

(alkyl)₂N-(alkylene-NX)_nH II)

wherein each alkyl independently is selected from methyl, ethyl, propyl, and butyl, wherein each alkylene independently is selected from methylene, ethylene, propylene or (iso)butylene, and each X, independently, is H or C1-4 alkyl and n is 1, 2, 3, 4, 5, or 6,

followed by

quaternizing amine functions of the amidoamine with a quaternizing agent that is halogen-free, sulfur-free, and phosphate-free to form a quaternary ammonium compound, and

subsequently reacting the quaternary ammonium compound with one or more fatty acids comprising 8 to 26 carbon atoms to exchange an anion of the quaternizing agent by an anion of said fatty acid.
