Abstract:
A method of increasing the viscosity of surfactant-containing compositions, where a thickening amount of at least one acylated polymeric polyamide is added to the composition, wherea) some of the polyamine nitrogen atoms of the acylated polymeric polyamine carry acyl radicals of the formula I R1â€”Câ€”â€ƒâ€ƒ(I) â€ƒin which R1 is selected from C7- to C27-alkyl, C7- to C27-alkenyl and C7- to C27-hydroxyalkyl, and b) some of the polyamine nitrogen atoms of the acylated polymeric polyamine carry acyl radicals of the formula II R2â€”Câ€”â€ƒâ€ƒ(II) â€ƒin which R2 is selected from hydrogen, C1- to C6-alkyl and C1- to C6-hydroxyalkyl where from 0.3 to 15% of the polyamide nitrogen atoms have an acyl radical of the formula I.
