• German patent DE-C1 43 33 100 the applicant has already proposed stable and sufficiently viscous aqueous bleaching and cleaning agents based on hypochlorites, fatty alcohol ether sulfates and amine oxides, which contain amine oxide phosphonic acids as a mandatory component. Even if the preparations are not objectionable from an application point of view, the use of phosphonic acids is not without problems with regard to the introduction of phosphorus compounds into surface waters. Since the amine oxide phosphonic acids are also comparatively expensive ingredients, there continues to be a need on the market for simple, viscous formulations which are characterized by high storage stability, chlorine resistance and good dispersing properties with a low hypochlorite content. The object of the invention was therefore to provide new aqueous bleaching and disinfecting agents which are free from the disadvantages described.
