Abstract

Silicate free detergent granules contain a seed crystal for calcium carbonate, such as calcite, a non-soap detergent active, especially an anionic active and a sugar such as sucrose to provide good mechanical strength, good dispersibility and other benefits. An alkali metal (e.g. sodium) carbonate may be present in the granules. The granules may be used as such to wash fabrics or may be added to a composition containing sodium carbonate and other conventional ingredients. The granules may be made by spray-drying or pan granulation.
