Mild detergent compositions which exhibit good cleaning performance comprise detergent surfactants and small amounts of protease. A preferred embodiment additionally contains suds boosters and divalent ions.

Light duty liquid or gel dishwashing detergent compositions containing

Automatic dishwashing detergent compositions comprising a certain combination of metasilicate with other silicate (polymeric) components are disclosed. Particularly preferred compositions also comprise low foaming surfactant and detergency builders.

Monomeric rich silicate system in automatic dishwashing composition with

A viscoelastic, thixotropic, liquid automatic dishwashing detergent composition which is substantially free of chlorine bleach and silicate and contains enzyme(s), an enzyme stabilizing system, and a detergent surfactant or detergent builder is provided. It has a product pH between about 7 and about 11.

Thixotropic liquid automatic dishwashing composition with enzyme

Disclosed is a process for making nonphosphated automatic dishwashing detergents which have granular form and comprise a conventional nonphosphorus builder system consisting essentially of an organic builder salt (such as citrate) and a dispersant (such as a polyacrylate); and an oxygen bleach system comprising a chelant (such as ethylenediamine disuccinate) and a bleach active (such as perborate or percarbonate) optionally with enzymes and/or dry-mixed hydrous silicates. The invention secures stable, free-flowing granules by a premix step in which the chelant and dispersant are brought together; a drying step using conventional equipment; and one or more admix steps in which the bleach active is mixed with the product of the drying step.
