Abstract:
This invention relates to N-alkyl-N′-poly(oxyalkyl)hexapyrimidine-quaternary ammonium salts of the formulae (Ia)-(Ic) and mixtures thereof in which R1 is C8-C30-alkyl or C8-C30-alkenyl, R2 is hydrogen, C1-C3-alkyl, —COOH or a group selected from the formulae wherein the bonding occurs via the valence containing the B residue, B is a single bond or a C1 to C3 alkylene group R3 is C1-C4-alkyl, vinyl or allyl, X− is methylsulfate or iodide, A is a 1,2-alkylene group having from 2 to 10 carbon atoms, and p is a number from 1 to 50.
