Automatic dishwashing detergent compositions comprising certain cobalt catalysts are provided. More specifically, the invention relates to automatic dishwashing detergents which provide enhanced cleaning/bleaching benefits (especially tea stain removal) through the selection of cobalt catalysts having the formula: [Co(NH3)n(X)m] T y. Preferred automatic dishwashing compositions comprise amylase and/or protease enzymes. Included are methods for washing tableware in domestic automatic dishwashing appliances using the cobalt catalysts.
On décrit des compositions de détergent de lavage automatique de la vaisselle qui comprennent certains catalyseurs à base de cobalt. Plus particulièrement, l'invention se rapporte à des détergents de lavage automatique de la vaisselle qui offrent des propriétés avantageuses de nettoyage/blanchiment (notamment l'enlèvement des marques de thé) grâce à la sélection de catalyseurs à base de cobalt possédant la formule [Co(NH3)n(X)m]Ty. Des compositions préférées de lavage automatique de la vaisselle comprennent des enzymes amylases et/ou protéases. On décrit également des procédés de lavage de vaisselle de table dans des machines à laver la vaisselle, automatiques et domestiques, à l'aide de catalyseurs à base de cobalt.
