A multi-phase detergent tablet for use in a washing machine, the tablet comprising a first phase in adhesive contact with one or more second phases, and wherein at least the first phase is in the form of a compressed particulate solid incorporating a cogranulated detergency additive composition comprising polymeric polycarboxylate and inorganic carrier. The multi-phase tablets provide improved interphase adhesivity, robustness and strength together with excellent dissolution and cleaning characteristics.

Detergent tablet

A process for preparing a detergent tablet comprises the steps of compressing a composition comprising an active detergent component to form a compressed portion and delivering a composition comprising an active detergent component in the form of a solid, liquid or gel to the compressed portion to form a non-compressed, non-encapsulating portion.

Process for preparing detergent tablet

A process for making a detergent composition comprising solid components which form a total particulate base detergent matrix and a liquid hydrocarbon component, the process comprises the steps of applying liquid hydrocarbon onto a high porosity fraction selected from the total particulate base detergent matrix.

Process for making tabletted detergent compositions

A process for making a detergent tablet suitable for use in laundry or automatic dishwashing by tabletting a detergent composition comprising solid components which form a total particulate base detergent matrix and non-aqueous liquid components having viscosity of 1000 cp or less is disclosed. The process involves the steps of applying the non-aqueous liquid components having viscosity of 1000 cp or less onto a low porosity fraction selected from the total particulate base detergent matrix.
