Automatic dishwashing detergent compositions comprising a pH profile wherein the initial wash solution quickly rises to a high alkaline pH followed by a reduction in the pH to yield a final pH of less than 9.5 are disclosed. Compositions are substantially phosphate free and comprise a peroxygen bleach and activator. Particularly preferred compositions are granular and further comprise low levels of silicate for additional glasscare benefits.
L'invention se rapporte à des compositions détergentes pour lave-vaisselle comprenant un profil de pH tel qu'il se produit, dans la solution de lavage initial, une élévation rapide du pH jusqu'à un niveau alcalin élevé, puis une diminution de ce pH pour donner un pH final inférieur à 9,5. Ces compositions sont pratiquement exemptes de phosphates et comprennent un agent de blanchiment au peroxyde ainsi qu'un activateur de blanchiment. On préfère tout particulièrement des compositions granulaires qui comprennent en outre des faibles nivaux de silicate afin de prendre encore mieux soin de la verrerie.
