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 (.DELTA.pH) 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.

L'invention porte sur des pastilles détergentes pour machines à laver comportant une première phase d'un agent alcalinisant et une deuxième phase d'un agent acidifiant, et présentant un pH d'au moins 9 et de préférence de 9,5 et un indice de variation de pH ( DELTA pH) inférieur à 0,15 unités/minute. Les pastilles préférées sont celles dont l'agent alcalinisant est un silicate ou un mélange de silicates et en particulier un silicate de sodium de la variété cristalline stratifiée, tandis que l'agent acidifiant est une partie d'un couple effervescent bicarbonate /acide agissant comme désagrégateur de la pastille. Lesdites pastilles ont un effet régulateur sur le pH, un pouvoir détergent et des performances enzymatiques améliorés ainsi qu'une solidité, une intégrité et des caractéristiques de dissolution élevées.
