    摘要： The invention relates to a bleaching composition containing an oxidant bleach and enzyme granules, in which enzyme stability is prolonged without undue loss of solubility despite intimate contact of said enzyme granules and said oxidant bleach, comprising:an oxidant bleach, selected from the group consisting of alkali-metal peroborates, alkali metal percarbonates, hydrogen peroxide adducts, and mixtures thereof and hydrolase enzyme granules comprising a hydrolase enzyme core and a water soluble alkali metal silicate coating substantially encapsulating said core, said coating including at least one protective agent, said agent being selected from the group consisting of transition metals; reducing agents; and mixtures thereof. Sodium percarbonate is a preferred oxidant, while transition metals combined with a sodium silicate coating provide enhanced storage stability to the enzymes thereby coated.

    摘要： Bleaching compositions are provided that comprise peracid activators. The peracid activators are ester derivatives of a carboxylic acid where the oxygen is covalently bound through a polyhydroxy linking group to a leaving group that is displaceable in a peroxygen bleaching solution by perhydroxide anion. When the peracid activator is combined with a source of peroxygen in aqueous solution, then a stain removing peracid is formed. One embodiment of the peracid activator has the structure ##STR1## where R' is a branched or linear C.sub.4-12 alkyl, n is 1 to about 7, and L is a leaving group.

    摘要： A number of novel peracid precursors each have the general structure: ##STR1## wherein: Z is a leaving group, the conjugate acid of the leaving group being in the range of from about 4 to 15; R is a substituted or unsubstituted alkyl or alkenyl group having from about 1 to 18 carbon atoms; and M is hydrogen or an alkali or alkaline earth metal. A method is also disclosed for synthesizing a product as represented above wherein succinic anhydride, including an R constituent as defined above is dissolved in a water-miscible, non-nucleophilic solvent and an acid including a Z constituent as defined above is neutralized and deprotonated to form a nucleophile, the substituted anhydride and the nucleophile being combined to form the product. The product is a component in a dry bleach product, optionally including other adjuncts.

    摘要： A bleaching product and a method of removing soils from fabrics by contacting the fabrics in an aqueous wash solution with a product comprising a peracid precursor, a source of hydrogen peroxide and a source for delayed release of an acid into the wash solution to initially permit effective in situ formation of peracid, the acid thereafter reducing the pH of the wash solution for enhancing bleach performance of the peracid. The source of the acid may be included in the bleaching product, for example, as an acid of delayed solubility, an acid coated with a low solubility agent or an acid generating species, or independent of the bleaching product. The acid source is selected to be compatible with the peracid or precursor and adjuncts. The method for removing soils thus comprises contacting the fabrics in an aqeuous solution with a peracid precursor and a source of hydrogen peroxide, initially raising the pH of the solution for effective in situ formation of peracid and then reducing the pH for enhancing bleach performance of the peracid.

    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.
