Title
(EN) BLEACHING WITH POLYOXOMETALATES AND AIR OR MOLECULAR OXYGEN
(FR) BLANCHIMENT A L'AIDE DE POLYOXOMETALATES ET D'AIR OU D'OXYGENE MOLECULAIRE
Abstract
(EN)
A method for bleaching laundry and household surfaces is provided which includes preparing a wash medium with a bleaching composition incorporating polyoxometalates and being free of any effective amount of a bleaching agent such as hydrogen peroxide, organic peracids, inorganic peracids, organic persalts, inorganic persalts, Caro's acid, Caroates and mixtures thereof. A second step involves contacting a stained substrate such as a fabric, kitchenware or a household hard surface for a time and in an amount sufficient to remove the stains. Air is employed as a primary source of oxygen atoms for bleaching.
(FR)
Procédé de blanchiment de linge et de surfaces domestiques, consistant à préparer une substance de lavage à l'aide d'une composition de blanchiment qui contient des polyoxométalates et est exempte de toute quantité efficace d'un agent de blanchiment tel que du peroxyde d'hydrogène, des peracides organiques, des peracides inorganiques, des persels organiques, des persels inorganiques, de l'acide de Caro, des caroates et des mélanges desdites substances. Ledit procédé consiste ensuite à mettre en contact un substrat taché tel qu'un tissu, un ustensile de cuisine ou une surface domestique dure pendant un laps de temps suffisant et en quantité suffisante pour enlever les taches. De l'air est employé en tant que source primaire d'atomes d'oxygène pour le blanchiment.
