    摘要: In one embodiment, the invention provides a stable peracid bleach composition comprising discrete granules which comprise peracid, namely, diperoxydodecanedioic acid. In another preferred embodiment, enzymes are present in the composition separate from the discrete peracid granules. In both the enzyme-containing and non-enzyme containing compositions, peracid and exotherm control agents are combined in a discrete granule in which the amount of water is carefully controlled to result in, respectively, maximum peracid and enzyme stability. Standard bleaching composition adjuncts such as fillers, brighteners, pH control agents and the like may be included in the compositions apart from the discrete peracid granules.

    摘要: Methods and compositions for increased stability of enzymes in oxidant dry bleach. Enzyme stability is adversely affected by increased temperature, humidity, and the presence of strong oxidants, such as peracids. The instant invention provides enzyme stability in the presence of oxidant bleaches by coating or encapsulating the enzyme, while providing enzyme solubility suitable for use in bleach mixtures upon introduction to an aqueous medium. Particularly, alkali and neutral materials act as protection agents, which neutralize oxidant species before the contact and denature the enzyme. Other standard bleaching composition adjuncts such as builders, fillers, buffers, brighteners, fragrances, and the like may be included in the enzyme-containing oxidant bleach composition in addition to the discrete coated enzyme granules.
