ABSTRACT:
The invention relates to a composition suitable for cleaning disinfection and bleaching comprising an acidic aqueous solution of hydrogen peroxide, a surfactant, and a phosphonic acid based complexing agent selected from biodegradable 1-aminoalkane-1,1-diphosphonic acids, or salts thereof, of the formula: ##STR1## wherein R.sub.1 is selected from hydrogen, C.sub.1 -C.sub.4 alkyl and phenyl; R.sub.2 and R.sub.3, independently from each other, are selected from hydrogen, C.sub.1 -C.sub.22 alkyl, C.sub.5 -C.sub.6 cycloalkyl, phenyl, C.sub.7 -C.sub.18 alkylphenyl, C.sub.7 -C.sub.18 phenylalkyl, a C.sub.1 -C.sub.10 alkanol radical, a carboxy alkyl radical having up to 10 carbon atoms, wherein R.sub.2 and R.sub.3 together with the nitrogen atom can form a piperidino, pyrrolidino or a morpholino group; and X.sub.1 to X.sub.4, independently from each other, are selected from hydrogen, alkali metal and ammonium. The invention also relates to use of such a composition for disinfection, bleaching, removal of stains from textiles, or removal of lime deposits.
