Abstract

Una composición blanqueadora que comprende un ligando orgánico que forma un complejo con un metal de transición para blanquear un substrato con oxígeno atmosférico, la composición blanqueadora al ser agregado a un medio acuoso brinda un medio de blanqueo acuoso substancialmente desprovisto de blanqueador de peroxígeno o un sistema blanqueador a base de peroxi o generador de peroxilo, 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. La composición blanqueadora se la utiliza particularmente en un líquido comercial de "blanqueo con aire" y en un formato de blanqueo con peroxilo o "blanqueo con aire" granulado. Se divulga también un procedimiento para blanquear una mancha que emplea a la composición.A bleaching composition comprising an organic ligand that forms a complex with a transition metal for bleaching a substrate with atmospheric oxygen, the bleaching composition being added to an aqueous medium provides an aqueous bleaching medium substantially devoid of peroxygen bleach or a system peroxy bleach or peroxyl generator, together with an oxidizable precursor selected from 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. The bleaching composition is particularly used in a commercial "air bleach" liquid and in a peroxyl bleach or granulated "air bleach" format. A method for bleaching a stain that employs the composition is also disclosed.
