Detergent compositions and methods of making them |
(57) Zeolite detergent builders which are substantially free from water and which comprise
a polyether or polyalcohol enable improved non aqueous detergent compositions to be
made. They may be produced by contacting a corresponding zeolite which contains water
with the polyether or polyalcohol and evaporating the water.
