Abstract
Blanqueo catalítico de substratos, en especial de telas para lavar, con un catalizador de blanqueo y peróxido en presencia de un sistema mejorador de blanqueo enzimático. Reivindicación 1: Una composición blanqueadora que comprende un ligando orgánico que forma un complejo con un metal de transición para blanquear un substrato con un blanqueador de peroxígeno o fuente del mismo, y un blanqueador de peroxígeno o fuente del mismo, junto con un precursor oxidable seleccionado entre el grupo que comprende: (i) un ácido insaturado o sal de metal alcalino del mismo; y (ii) un sistema generador para producir un ácido insaturado in situ en un medio acuoso, junto con una enzima para oxidar el precursor oxidable para formar un hidroperóxido in situ. Reivindicación 20: Un procedimiento para blanquear una mancha, que comprende las etapas que consisten en tratar una tela con una composición blanqueadora que comprende un ligando orgánico que forma un complejo con un metal de transición para blanquear un substrato con un blanqueador de peroxígeno o fuente del mismo, junto con un precursor oxidable seleccionado entre el grupo que comprende: (i) un ácido insaturado o sal de metal alcalino del mismo; y (ii) un sistema generador para producir un ácido insaturado in situ en un medio acuoso, y una enzima para oxidar el precursor oxidable para formar un hidroperóxido in situ.Catalytic bleaching of substrates, especially fabrics for washing, with a bleaching catalyst and peroxide in the presence of an enzyme bleaching improver system. Claim 1: A bleaching composition comprising an organic ligand that complexes with a transition metal to bleach a substrate with a peroxygen bleach or source thereof, and a peroxygen bleach or source thereof, together with a selected oxidizable precursor among the group comprising: (i) an unsaturated acid or alkali metal salt thereof; and (ii) a generating system for producing an unsaturated acid in situ in an aqueous medium, together with an enzyme to oxidize the oxidizable precursor to form a hydroperoxide in situ. Claim 20: A method for bleaching a stain, comprising the steps of treating a fabric with a bleaching composition comprising an organic ligand that complexes with a transition metal to bleach a substrate with a peroxygen bleach or source of the same, together with an oxidizable precursor selected from the group comprising: (i) an unsaturated acid or alkali metal salt thereof; and (ii) a generating system to produce an unsaturated acid in situ in an aqueous medium, and an enzyme to oxidize the oxidizable precursor to form a hydroperoxide in situ.
