ABSTRACT:
Timed-release bleaching compounds containing encapsulated hypochlorite bleaching agents are disclosed, along with a method for using the compounds. A preferred embodiment of the invention includes sodium silicate-coated lithium hypochlorite. One or more additional coatings to further delay timed release are optional. The novel bleach compounds are especially useful in reducing fabric and dye damage in fabric bleaching while facilitating the inclusion of optional laundry additives such a enzymes and brighteners. The encapsulates have good shelf stability and are effective over a wide range of temperatures and concentrations.
