Description: Bleaching Compositions Technical field The present invention relates to bleach-containing compositions, suitable for use in laundry washing methods. Background to the Invention In the past decades research efforts have been directed towards the development of bleaching systems, based on organic peroxyacids, which can provide effective stain and/or soil removal from fabrics at lower wash temperatures. The organic peroxyacids are often obtained by the in situ perhydrolysis of organic peroxyacid bleach precursor compounds (bleach activators). A commonly employed precursor compound is tetraacetyl ethylene diamine (TAED) which provides effective hydrophilic cleaning especially on beverage stains. To achieve effective bleaching of a detergent, both hydrophobic and hydrophilic stains need to be bleached by the bleach system. Further organic peroxyacid precursors have thus been developed to deal with hydrophobic stains and soils. Various documents disclose the use of mixtures of hydrophobic and hydrophilic bleaches in detergents, for example JP 7-238298 DE 196,16, 782, WO94/28103. However, the inventors have found that most prior art bleaching compositions do not always perform satisfactory when used under stressed conditions, such as low temperature washing, washing with limited agitation, use of low quantities of detergent actives, highly soiled fabrics, presence of high levels of metal ions, or after storage under humid or high temperature. These problems occur in particular in low density detergents, in particular when the overall level of the bleach system in the detergent composition is low, and also in detergents which contain high levels of phosphate-builder, which may introduce metal ions to the wash. Furthermore, to achieve an efficient bleach system, the system should provide excellent bleaching at low levels, thereby minimizing the chance of damage to the fabrics. Thus, there is a need to provide detergent compositions which comprise low levels of a bleaching system, which has a very effective bleaching performance under stressed conditions, on both hydrophobic soils and hydrophilic soils. The inventors have now surprisingly found that improved bleaching under stressed conditions can be achieved by use of a bleaching-composition containing a low level of bleach activators and peroxide source, namely having an available oxygen (AvO) derived from hydrophobic and hydrophilic bleach activators of less than 5000 ppm, and having a specific ratio of AvO of the hydrophobic activator to the AvO of the hydrophilic activator, namely from 3:1 to 1:50, and a specific ratio of the total AvO to the AvO of the activators, namely more than 2:1. The bleach system has been found to be particularly useful in low density detergents, in hand washing detergents, in phosphate-containing compositions, and also in washing processes where a low concentration of detergent is used. In general, bleach and in particular hypochlorite bleach is known to kill bacteria. High levels of bleach are normally required to provide a sufficient reduction of the bacteria's or to eliminate the bacteria's. Therefore, most detergents which comprise bleach systems known in the art, which only comprise low levels of bleach, are not effective as biocide agents for sanitization. The inventors have found that mixed bleach systems, comprising specific levels and ratios of hydrophobic, hydrophilic bleach additives and peroxide sources are very useful as biocide agents. They have found that even the use of low levels of specific bleach compositions in wash solutions or in detergents or cleaning agents, provides effective sanitization of the washed fabrics or surfaces, or effective reduction of the bacterias when the bleaching components are used in the specific ratios, mentioned herein. All documents cited in the present description are, in relevant part, incorporated herein by reference.

SRA's also include: simple copolymeric blocks of ethylene terephthalate or propylene terephthalate with polyethylene oxide or polypropylene oxide terephthalate, see U.S. 3,959,230 to Hays, May 25, 1976 and U.S. 3,893,929 to Basadur, July 8, 1975; cellulosic derivatives such as the hydroxyether cellulosic polymers available as METHOCEL from Dow; the C1 -C4 alkyl celluloses and C4 hydroxyalkyl celluloses, see U.S. 4,000,093, December 28, 1976 to Nicol, et al.; and the methyl cellulose ethers having an average degree of substitution (methyl) per anhydroglucose unit from about 1.6 to about 2.3 and a solution viscosity of from about 80 to about 120 centipoise measured at 20°C as a 2% aqueous solution. Such materials are available as METOLOSE SMI 00 and METOLOSE SM200, which are the trade names of methyl cellulose ethers manufactured by Shin-etsu Kagaku Kogyo KK. Additional classes of SRA's include: (I) nonionic terephthalates using diisocyanate coupling agents to link polymeric ester structures, see U.S. 4,201,824, Violland et al. and U.S. 4,240,918 Lagasse et al.; and (II) SRA's with carboxylate terminal groups made by adding trimellitic anhydride to known SRA's to convert terminal hydroxyl groups to trimellitate esters. With the proper selection of catalyst, the trimellitic anhydride forms linkages to the terminals of the polymer through an ester of the isolated carboxylic acid of trimellitic anhydride rather than by opening of the anhydride linkage. Either nonionic or anionic SRA's may be used as starting materials as long as they have hydroxyl terminal groups which may be esterified. See U.S. 4,525,524 Tung et al.. Other classes include: (III) anionic terephthalate-based SRA's of the urethane-linked variety, see U.S. 4,201,824, Violland et al.; Other Optional Ingredients Other optional ingredients suitable for inclusion in the compositions of the invention include perfumes, colours and filler salts, with sodium sulfate being a preferred filler salt. Highly preferred may be the inclusion of speckle particles. The following speckle particle is a preferred speckle particle: Sodium carbonate particles, having 75 % of particles having a particle size of from 600 microns to 850 microns and 25% of particles having a particle size of from 425 microns to 600 microns are obtained by agglomerating and sieving sodium carbonate powder. The thus obtained particles are sprayed with a Monastral blue BV paste solution and subsequently dried, obtaining speckle particles comprising about lOOOppm of dye. Highly preferred compositions contain from about 2% to about 10% by weight of an organic acid, preferably citric acid. Also, preferably combined with a carbonate salt, minor amounts (e.g., less than about 20% by weight) of neutralizing agents, buffering agents, phase regulants, hydrotropes, enzyme stabilizing agents, polyacids, suds regulants, opacifiers, anti-oxidants, bactericides and dyes, such as those described in US Patent 4,285,841 to Barrat et al., issued August 25, 1981 (herein incoφorated by reference), can be present. Form of the Compositions The detergent composition of the invention can be made via a variety of methods, including dry-mixing and agglomerating and/ or spray-drying of the various compounds comprised in the detergent component. The compositions in accordance with the invention can take a variety of physical forms including liquid and solid forms such as tablet, flake, pastille and bar, and preferably granular forms. The compositions in accord with the present invention can also be used in or in combination with bleach additive compositions, for example comprising chlorine bleach. Chlorine-Based Bleach The detergent compositions can include as an additional component a chlorine-based bleach. However, since preferred detergent compositions of the invention are solid, most liquid chlorine-based bleaching will not be suitable for these detergent compositions and only granular or powder chlorine-based bleaches will be suitable. Alternatively, the detergent compositions can be formulated such that they are chlorine-based bleach-compatible, thus ensuring that a chlorine based bleach can be added to the detergent composition by the user at the beginning or during the washing process. The chlorine-based bleachis such that a hypochlorite species is formed in aqueous solution. The hypochlorite ion is chemically represented by the formula OCT. Those bleaching agents which yield a hypochlorite species in aqueous solution include alkali metal and alkaline earth metal hypochlorites, hypochlorite addition products, chloramines, chlorimines, chloramides, and chlorimides. Specific examples of compounds of this type include sodium hypochlorite, potassium hypochlorite, monobasic calcium hypochlorite, dibasic magnesium hypochlorite, chlorinated trisodium phosphate dodecahydrate, potassium dichloroisocyanurate, sodium dichloroisocyanurate sodium dichloroisocyanurate dihydrate, trichlorocyanuric acid, l,3-dichloro-5,5-dimethylhydantoin, N-chlorosulfamide, Chloramine T, Dichloramine T, chloramine B and Dichloramine B. A preferred bleaching agent for use in the compositions of the instant invention is sodium hypochlorite, potassium hypochlorite, or a mixture thereof. A preferred chlorine-based bleach can be Triclosan (trade name). Most of the above-described hypochlorite-yielding bleaching agents are available in solid or concentrated form and are dissolved in water during preparation of the compositions of the instant invention. Some of the above materials are available as aqueous solutions. The mean particle size of the components of the granular compositions in accordance with the invention, should preferably be such that no more that 25% of the particles are greater than 1.8mm in diameter and not more than 25% of the particles are less than 0.25mm in diameter. Preferably the mean particle size is such that from 10% to 50% of the particles has a particle size of from 0.2mm to 0.7mm in diameter. The term mean particle size as defined herein is calculated by sieving a sample of the composition into a number of fractions (typically 5 fractions) on a series of sieves, preferably Tyler sieves. The weight fractions thereby obtained are plotted against the aperture size of the sieves. The mean particle size is taken to be the aperture size through which 50% by weight of the sample would pass. Laundry Washing Method Machine laundry methods herein typically comprise treating soiled laundry with an aqueous wash solution in a washing machine having dissolved or dispensed therein an effective amount of a machine laundry detergent composition in accord with the invention. By an effective amount of the detergent composition it is meant from lOg to 300g of product dissolved or dispersed in a wash solution of volume from 5 to 65 litres, as are typical product dosages and wash solution volumes commonly employed in conventional machine laundry methods. In a preferred use aspect the detergent composition is formulated such that it is suitable for hand washing. In another preferred aspect the detergent composition is a pre-treatment or soaking composition, to be used to pre-treat or soak soiled and stained fabrics.
