The invention relates to the Quaternary ammonium salts of N-alkyl-N'-poly (oxyalkyl) hexahydropyrimidine of the formulas (Ia) - (Ic), and their mixtures, in which R is a CC-alkyl or CC-alkenyl, R is hydrogen, CC-alkyl, -COOH or a group selected from formulas (Id) - (Ig), in which binding occurs via valence bonds containing a residue B, where B is a single bond or a C1-C alkylene group, R 5 is CC-alkyl, vinyl, allyl or benzyl , X denotes methyl sulfate or iodide, A represents a 1,2-alkylene group having from 2 to 10 carbon atoms, and p significant number from 1 to 50. |
