The present invention discloses a method for manufacturing a laundry detergent, characterized by the following steps: (a) incorporating oxygen donors and their activators in a waxy matrix which is surrounded by an ionic polymer layer for providing a capsule system, (b) incorporating the capsule system into a liquid washing detergent. Furthermore, a liquid washing detergent is disclosed, characterized by a capsule system comprising a waxy matrix which is surrounded by an ionic polymer layer and into which oxygen donors and their activators are incorporated. Furthermore, a method for manufacturing a heavy-duty laundry detergent wipe is disclosed, characterized by the following steps: (a) incorporating oxygen donors and their activators in a waxy matrix which is surrounded by an ionic polymer layer for providing a capsule system, (b) incorporating the capsule system into a dispersion comprising a liquid washing detergent and a water insoluble functional additive, (c) applying the dispersion provided with the capsule system to a carrier material which is solid at ambient temperature. Furthermore, a method for manufacturing a heavy-duty laundry detergent wipe is disclosed, characterized by the following steps: (a) incorporating oxygen donors and their activators in a waxy matrix which is surrounded by an ionic polymer layer for providing a capsule system, (b) incorporating the capsule system into a carrier material which is solid at ambient temperature, (c) applying a dispersion comprising a liquid washing detergent and a water insoluble functional additive to the carrier material provided with the capsule system. Furthermore, a heavy-duty laundry detergent wipe is disclosed, comprising a carrier material which is solid at ambient temperature and a dispersion comprising a liquid washing detergent and a water insoluble functional additive and which has been applied to the carrier material, characterized in that the heavy-duty detergent wipe further comprises a capsule system which has been incorporated into the dispersion or directly into the carrier material and which comprises oxygen donors and their activators incorporated into a waxy matrix surrounded by an ionic polymer layer.
