BLEACH CATALYST PLUS ENZYME PARTICLES

Abstract: Composite particles comprise a bleach catalyst plus one or more detersive enzymes. The particles are especially useful in automatic dishwashing compositions. Thus, a cobalt (III) or manganese (III) bleach catalyst is combined with protease or amylase enzymes and a carrier. The resulting particles are used in combination with perborate or percarbonate bleach to clean dishware in an automatic machine.

Description: BLEACH CATALYST PLUS ENZYME PARTICLES TECHNICAL FIELD The present invention relates to particles which contain bleach catalysts and enzymes These particles are particularly useful components of detergent compositions, such as laundry detergent compositions, hard surface cleaners, and especially automatic dishwashing detergent compositions BACKGROUND OF THE INVENTION Automatic dishwashing, particularly in domestic appliances, is an art very different from fabric laundering Domestic fabric laundering is normally done in purpose-built machines having a tumbling action These are very different from spray-action domestic automatic dishwashing appliances The spray action in the latter tends to cause foam Foam can easily overflow the low sills of domestic dishwashers and slow down the spray action, which tn turn reduces the cleaning action Thus, in the distinct field of domestic machine dishwashing, the use of common foam- producing laundry detergent surfactants is normally restricted These restrictions represent but one illustration o the unique formulation constraints in the domestic dishwashing field Automatic dishwashing with bleaching chemicals is likewise different from fabric bleaching In automatic dishwashing, the use of bleaching chemicals mainly involves the promotion of soil removal from dishes, though some soil bleaching may also occur Additionally, soil antiredeposition and anti-sporting effects from bleaching chemicals sometimes desirably occur Some bleaching chemicals (such as a hydrogen peroxide source, alone or together with tetraacetylethylenediamine, TAED) can, in certain circumstances, be helpful for cleaning dishware, but this technology gives far from satisfactory results in a dishwashing context for example, the ability to remove tough tea stains is limited, especially in hard water, and requires rather large amounts of bleach Other bleach activators developed for laundry use can even cause negative effects, such as creating unsightly deposits, when used in an automatic dishwashing product, especially when such activators have low water solubility Other bleach systems can damage items unique to dishwashing, such as silverware, aluminum cookware or certain plastics In contrast with fabnc laundering, the incorporation of detersive enzymes tnto automatic dishwashing detergents (ADD's) is a relatively new concept However, it has been determined that the use of detergent protease, amylase, etc , enzymes in dishwashing compositions provides improved cleaning performance on a vanety of soils A recognized need in ADD compositions is to have present one or more ingredients which improve the removal of hot beverage stams (e g , tea, coffee, cocoa, etc ) from consumer articles Strong alkalis like sodium hydroxide, bleaches such as hypochlorite, builders such as phosphates and the like can help in varying degrees Moreover, improved ADD's make use of a source of hydrogen peroxide, optionally with a bleach activator such as TAED, as noted In addition enzymes such as commercial proteolytic and amylolytic enzymes (e g SAVINASE® TERMAMYL® and DURAMYL® available from Novo Nordisk S A) can be used The alpha-amylase :omponent provides at least some benefit with respect to the starchy soil removal properties of the ACD ADD s containing amylases typically can also deliver a somewhat more moderate wash pH in use, and can remove starchy soils while avoiding delivering large weight equivalents of sodium hydroxide on a per-gram-of-product basis It has been also discovered that certain bleach catalysts comprising cobalt or nanganese compounds are particularly effective for use in promoting the cleaning properties of ADD's However, the direct incoφoration of the small bleach catalyst particles at typically very low levels into a granular ADD composition can present problems Such granular compositions typically should be made up of particles having mean sizes which are all similar to each other in order to avoid segregation of components in the composition Such compositions often comprise panic les having mean particles size in a defined range of from about 400 to about 2400 microns, more usually from about 500 to about 2000 microns, to achieve good flow and absence of dustiness propelies Any fine or oversize particles outside these limits must generally be removed by sieving to avoid a particle segregation problem The addition of fine particle bleach catalysts into conventional granular detergent products thus potentially presents a component separation problem F ine bleach catalyst particles in a detergent composition matrix may also cause chemical stability problems caused by a tendency of the fine particles to interact with other components of the overall composition From the foregoing, it will be appreciated by those skilled in the art that the formulation of modern automatic dishwashing detergents is becoming increasingly complex The need to separately manufacture, store, ship and formulate a wide variety of ingredients adds to the cost of such products Therefore, it would be desirable to combine two or more of such ingredients irto discrete particles, thereby avoiding some of the costs associated with the manufacture and handling of individual ingredients Unfortunately, the intimate contact between many such ingredients that is necessarily occasioned by their combination mto discrete particles make such combinations unworkable For example, strong bleaches or strong alkalis can be destructive of enzymes, especially on prolonged storage It has now been determined that detersive enzymes are stable in the presence of bleach catalysts Accordingly, it has now been determined that particles compπsmg bleacn catalysts together with detersive enzymes can be formulated for use in detergent compositions, especially ADD's These and other objects and advantages of the present invention will be seen from the following

typically are 3 1 to 15 1 The additional ligand also serves to scavenge vagrant metal ions such as iron and copper, thereby protecting the bleach from decomposition One possible such system is described in European patent application, publication no 549,271 While the structures of the bleach-catalyzing manganese complexes of the present invention have not been elucidated, it may be

the oxidation state of the manganese cation during the catalytic process is not known with certainty, and may be the (+11), (+III), (+IV) or ( V) valence state Due to the ligands' possible six points of attachment to the manganese cation it may be reasonably speculated that multi-nuclear species and/or "cage" structures may exist in ihe aqueous bleaching media Whatever the form of the active Mn Iigand species which actually exists, it functions in an apparently catalytic manner to provide improved bleaching performances on stubborn stams such as tea, ketchup, coffee, wine, juice, and the

Oxidative stability- enhanced amylases vs. the above-identified reference amylase are preferred for use, especially in bleaching, more preferably oxygen bleaching, as distinct from chlorine bleaching, detergent compositions herein. Such preferred amylases mclude (a) an amylase according to the herembefore mcoφorated WO 9402597, Novo, Feb. 3, 1994, as further illustrated by a mutant m which substitution is made, using alanine or threonine, preferably threonine, of the methionine residue located in position 197 of the B. licheniformis alpha-amylase, known as TERMAMYL®, or the homologous position variation of a similar parent amylase, such as B amyloliquefaciens, B subtilis, or B. stearothermophilus; (b) stability-enhanced amylases as described by Genencor International in a paper entitled "Oxidatively Resistant alpha-Amylases" presented at the 207th American Chemical Society National Meeting, March 13-17 1994, by C.

The enzyme-containing composite particles and/or overall detergent compositions herein may comprise from about 0 001% to about 20%, preferably from about 0 005% to about 8%, most preferably from about 0 01% to about 6%, by weight of an enzyme stabilizing system The enzyme stabilizing system can be any stabilizing system which is compatible with the detersive enzyme Such a system may be inherently provided by other formulation actives, or be added separately, e g , by the formulator or by a manufacturer of detergent-ready enzymes Such stabilizing systems can, for example, compnse calcium ion, bone acid, propylene glycol, short chain carboxylic acids, boronic acids, and mixtures thereof, and are designed to address different stabilization problems depending on the type of enzyme and type of detergent composition One stabilizing approach is the use of water-soluble sources of calcium and/or magnesium ions in the composite particles or in the finished compositions which provide such ions to the enzymes Calcium ions are generally more effective than magnesium ions and are preferred herein if only one type of cation is bemg used Enzymatic detergent compositions may compnse from about 1 to about 30, preferably from about 2 to about 20, more preferably from about 8 to about 12 millimoles of calcium ion per kg of finished detergent composition, though vaπation is possible depending on factors mcludmg the multiplicity, type and levels of enzymes incoφorated Preferably water-soluble calcium or magnesium salts are employed, mcludmg for example calcium chlonde, calcium hydroxide, calcium formate, calcium malate, calcium maleate, calcium hydroxide and calcium acetate, more generally, calcium sulfate or magnesium salts correspondmg to the exemplified calcium salts may be used Further creased levels of calcium and/or magnesium may of course be useful, for example for promoting the grease-cutting action of certain types of surfactant Another stabilizing approach is by use of borate species See Severson, U S 4,537,706 Borate stabilizers, when used, may be at levels of up to 10% or more of the composite particles or the finished composition, though more typically levels of up to about 3% by weight of boric acid or other borate compounds such as borax or orthoborate are used Substituted boric acids such as phenylboronic acid, butaneboronic acid, p-bromophenylboronic acid or the like can be used in place of boric acid and reduced levels of total boron in detergent compositions may be possible though the use of such substituted boron derivatives Stabilizing systems of certain cleaning compositions, for example ADD's, may further comprise from 0 to about 10%, preferably from about 0 01% to about 6% by weight, of chlorine bleach scavengers, added to prevent chlorine bleach species present in many water supplies from attacking and inactivating the enzymes, especially under alkaline conditions While chlorine levels in water may be small, typically in the range from about 0 5 ppm to about 1 75 ppm, the available chlorine in the total volume of water that comes in contact with the enzyme, for example during dish- or fabric-washing, can be relatively large, accordingly, enzyme stability to chlorine -use is sometimes problematic Since perborate or percarbonate, which have the ability to react with chlorine bleach, may be present in certain of the instant compositions in amounts accounted for separately from the stabilizing system, the use of additional stabilizers against chlorine may, most generally, not be essential, though improved results may be obtainable from their us. Suitable chlorine scavenger anions are widely known and readily available, and, if used, can be saits containing ammonium cations with sulfite, bisulfite, thiosulfite, thiosulfate, iodide, etc Antioxidants such as carbamate, ascorbate, etc , organic amines such as ethylenediaminetetracetic acid (EDTA) or alkali metal salt thereof, monoethanolamine (MEA), and mixtures thereof can likewise be used Likewise, special enzyme inhibition systems can be mcoφorated such that different enzymes have maximum compatibility Other conventional scavengers such as bisulfate, nitrate, chloride, sources of hydrogen peroxide such as sodium perborate tetrahydrate, sodium perborate monohydrate and sodium percarbonate, as well as phosphate, condensed phosphate, acetate, benzoate, citrate, formate, lactate, malate, tartrate, salicylate, etc , and mixtures thereof can be used if desired In general, since the chlorine scavenger function can be performed by mgredients separately listed under better recognized functions, (e g., hydrogen peroxide sources), there is no absolute requirement to add a separate chlorine scavenger unless a compound performing that function to the desired extent is absent from an enzyme-containing embodiment of the mvention, even then, the scavenger is added only for optimum results Moreover, the formulator will exercise a chemist's normal skill in avoiding the use of any enzyme scavenger or stabilizer which is majorly incompatible, as formulated, with other reactive mgredients, if used. In relation to the use of ammonium salts, such salts can be simply admixed with the detergent composition but are prone to adsorb water and/or liberate ammonia durmg storage Accordingly, such mateπals, if present, are desirably protected in a particle such as that described US 4,652,392, Bagmski et al Carner mateπal The composite catalyst enzyme particles herein are manufactured using one or more "carrier" matenals which incoφorate the catalyst and enzyme in a atnx Since the catalyst and enzyme are intended for use in an aqueous medium, the carrier material should dissolve or readily disperse in water under the intended use conditions tn order to release these mateπals to perform their detersive functions The dual benefits of catalytic bleach cleaning and enzymatic cleaning are thereby secured The carrier material should be men to reaction with the bleach catalyst and enzyme components of the particle under processing conditions and after granulation Additionally, the earner material should preferably be substantially free of moisture present as unbound water, as noted hereinafter In one mode, the carrier for the soluble or dispersible composite bleach catalyst/enzyme

Although water insolubility is an essential characteristic of the diacyl peroxide used in the present invention, the size of the particles containing it is also important for controlling residue formation in the wash and maximizing stain removal performance. Preferred diacyl peroxides used in the present compositions are also formulated into a carrier material that melts within the range of from about 38°C to about 77°C, preferably selected from the group consisting of polyethylene glycols, paraffin waxes, and mixtures thereof, as taught in copending U.S. patent application Serial Number 08/424,132, filed April 17, 1995. pH-Adjusting Control/Detergeπcy Builder Components The detergent compositions herein will preferably provide wash solutions having a pH of at least 7; therefore die compositions will typically comprise a pH-adjusting detergency builder component selected from water-soluble alkaline inorganic salts and water-soluble organic or inorganic builders.

See also U S Patents 3,933,672 and 4, 136,045 Highly prefeπed silicone suds suppressors are the compounded types known for use in laundry detergents such as heavy-duty granules, although types hitherto used only in heavy-duty liquid detergents may also be ircoφorated in the instant compositions For example, polydimethylsiloxanes having trimethylsilyl or alternate endblocking units may be used as the silicone These may be compounded with silica Jind/or with surface-active nonsihcon components, as illustrated by a suds suppressor compnsing 12% silicone/ silica, 18% stearyl alcohol and 70% starch in granular form A suitable commercial source of the silicone active compounds is Dow Coming Coφ Levels of the suds suppressor depend to some extent on the sudsing tendency of the composition, for example, an detergent composition for use at 2000 ppm comprising 2% octadecyldimethylamine oxide may not require the presence of a suds suppressor Indeed, it is an advantage of the present mvention to select cleaning-effective amine oxides which are inherently much lower in foam-forming tendencies than the typical coco amine oxides In contrast, formulations in which amine oxide is combined with a high-foaming anionic cosurfactant, e g , alkyl ethoxy sulfate, benefit greatly from the presence of suds suppressors Phosphate esters have also been asserted to provide some protection of silver <md silver- plated utensil surfaces, however, the instant compositions can have excellent silvercare without a phosphate ester component Without bemg limited by theory, it is believed that lower pH formulations, e g , those having pH of 9 5 and below, plus the presence ofthe essential amine oxide, both contnbute to improved silver care If it is desired nonetheless to use a phosphate ester, suitable compounds are disclosed in U S Patent 3,314,891, issued April 18, 1967, to Schmolka et al, mcoφorated herem by reference Prefeπed alkyl phosphate esters contain from 16-20

preferable to avoid the use of simple calcium-precipitating soaps as antifoams in the present compositions as they tend to deposit on the dishware Indeed, phosphate esters are not entirely free of such problems and the formulator will generally choose to minimize the content of potentially depositing antifoams in the instant compositions Coπosion Inhibitor The detergent compositions may contain
