Abstract

A multi-phase detergent tablet for use in a washing machine, the tablet comprising: a first phase comprising alkalising agent, and a second phase comprising acidifying agent, and wherein the multi-phase tablet has an initial pH of at least 9, preferably at least 9.5 and a pH rate change index (ΔpH) of no more than about 0.15 units/min. Preferred are multi-phase detergent tablets wherein the alkalising agent is a silicate or mixture of silicates, especially a sodium silicate of the crystalline layered variety; while the acidifying agent is part of a (bi)carbonate/acid effervescent couple which acts as disrupting agent for the tablet. The multi-phase detergent tablets have improved pH control, cleaning and enzyme performance together with excellent product strength, integrity and dissolution characteristics.
