摘要： A composition and method for inhibiting the extraction of transition metals from tableware washed in automatic dishwashers is described. The composition contains an aluminum species in which substantially all of the aluminum (III) ions are present as aluminum tetrahydroxide. A bleaching agent, a builder and optionally a surfactant and a silicate are present. The composition has a pH of less than about 10. A process for preparing the composition is also described.
