Abstract

Granular, phosphate-reduced, builder-containing detergent compositions containing a combination of natural layer silicates and fatty acid condensates. The fatty acid condensates are prepared by reaction of fatty acid triglycerides and hydroxyalkyl polyamines. The detergent compositions have an excellent softening effect both at low and high washing temperatures. The compositions provide synergistic softening effects, particularly at low temperatures.
