Abstract (en)

[origin: WO9851772A1] The invention relates to an enzymatic bleaching system containing new compounds that intensify enzymatic action, to be used with detergent substances containing a) at least one oxidation catalyst, b) at least one oxidizing agent, c) at least one mediator from the amide group, for example hydrazide or 1, 2, 4-triazolidine-3, 5-dione (urazole), and/or from the imide group, for example hydantoins, and/or from the oxocarbon group. To intensify the reaction, at least one mediation booster can be added, chosen from the following groups: NO-, NOH-, HRN-OH-compounds, hydrazides, urazoles, hydantoins, oxo-carbons or cation-forming substances of phenothiazine type, of phenoxazine type, of (R=N-N=R) type (e.g. ABTS), aryl-substituted alcohols (non-phenols), e.g. veratryl alcohol, special cation radical-forming phenoic compounds, radical cations in accordance with "Wurster" and radical anions.
