Irritant dusty powdered detergent components can be worked into substantially non-dusting form from a pre-mix comprising : a) from 1-10% by weight of a binder; and b) up to 40% by weight of a dusty detergent component; c) the balance being granulising particles capable of granulising the dusty detergent component in the presence of a binder. This pre-mix is used to prepare a granular detergent material having a core of granulising particles coated with said detergent component and a binder, comprising up to 40% by weight of the detergent component and from 1 to 10% by weight of the binder. The dusty detergent component and the granulising particles are admixed intimately and the resultant product is then admixed with the binder to form said pre-mix. Mixing of the pre-mix then continues until the granular detergent material is formed. |
