Abstract

Cationic non-silicate layer compounds corresponding to general formula (I) EQU Mg.sub.x Al(OH).sub.y A.sub.z. NH.sub.2 O (I) in which A represents an equivalent of a non-silicate anion, x has a value of from 1 to 5, y>z and (y+Z)=2X+3 and n is a number of 0 to 10, are used in phosphate-reduced detergents for reducing fabric incrustation.
