Definitions

• detergent compositions in tablet form are known in the art. It is understood that detergent compositions in tablet form hold several advantages over detergent compositions in paniculate form, such as ease of dosing, handling, transportation and storage.
• the first, second and/or optional subsequent phases can additionally comprise a non-disintegrant binder, i.e., a material that increases tablet strength without increasing tablet dissolution rate.
• a non-disintegrant binder i.e., a material that increases tablet strength without increasing tablet dissolution rate.
• Preferred non-disintegrant binders are selected from polyethylene and/or polypropylene glycols, for example polyethylene and/or polypropylene glycols having an average molecular weight of from about 1000 to about 12000, especially those of molecular weight 4000, 6000 and 9000.
• the polyethyleneglycol non- disintegrant binders are highly preferred herein.
• a preferred machine dishwashing method comprises treating soiled articles selected from crockery, glassware, silverware, metallic items, cutlery and mixtures thereof, with an aqueous liquid having dissolved or dispensed therein an effective amount of a the herein described compositions.
• an effective amount is meant from 8g to 60g of product dissolved or dispersed in a wash solution of volume from 3 to 10 litres, as are typical product dosages and wash solution volumes commonly employed in conventional machine dishwashing methods.
• the detergent tablets are from 15g to 40g in weight, more preferably from 20g to 35g in weight.
• the parent acids of the monomeric or oligomeric polycarboxylate chelating agents or mixtures thereof with their salts e.g. citric acid or citrate/citric acid mixtures are also contemplated as useful builder components.
• Borate builders, as well as builders containing borate-forming materials that can produce borate under detergent storage or wash conditions can also be used but are not preferred at wash conditions less that 50°C, especially less than 40°C.
• Crystalline layered sodium silicates of this type preferably have a two dimensional 'sheet' structure, such as the so called ⁇ -layered structure, as described in EP-A-0164514 and EP-A-0293640. Methods for preparation of crystalline layered silicates of this type are disclosed in DE-A-3417649 and DE-A-3742043.
• x in the general formula above has a value of 2,3 or 4 and is preferably 2.
• Examples of largely water insoluble builders include the sodium aluminosilicates.
• Suitable aluminosilicates include the alummosilicate zeolites having the unit cell formula Na z [(AlO2) 2; (SiO2)y]. XH2O wherein z and y are at least 6; the molar ratio of z to y is from 1.0 to 0.5 and x is at least 5, preferably from 7.5 to 276, more preferably from 10 to 264.
• the aluminosilicate material are in hydrated form and are preferably crystalline, containing from 10%. to 28%., more preferably from 18% to 22%o water in bound form.
• Nonionic surfactants Nonionic ethoxylated alcohol surfactants
• the high cloud point nonionic surfactant further have a hydrophile-lipophile balance ("HLB"; see Kirk Othmer hereinbefore) value within the range of from 9 to 15, preferably 11 to 15.
• HLB hydrophile-lipophile balance
• Such materials include, for example, Tergitol 15S9 (supplied by Union Carbide), Rhodasurf TMD 8.5 (supplied by Rhone Poulenc), and Neodol 91 -8 (supplied by Shell).
• Another suitable high cloud point nonionic surfactant is derived from a straight or preferably branched chain or secondary fatty alcohol containing from 6 to 20 carbon atoms (C6-C20 alcohol), including secondary alcohols and branched chain primary alcohols.
• Preferred enzymes include protease, amylase, lipase, peroxidases, cutinase and/or cellulase in conjunction with one or more plant cell wall degrading enzymes.
• the cellulases usable in the present invention include both bacterial or fungal cellulase. Preferably, they will have a pH optimum of between 5 and 12 and an activity above 50 CEVU (Cellulose Viscosity Unit). Suitable cellulases are disclosed in US-A-4,435,307, J61078384 and WO-A-96/02653 which disclose fungal cellulases produced respectively from Humicola insolens, Trichoderma, Thielavia and Sporotrichum.
• EP-A-0739982 describes cellulases isolated from novel Bacillus species. Suitable cellulases are also disclosed in GB-A-2075028; GB-A-2095275, DE-A-2.247.832 and WO-A-95/26398.
• L group The leaving group, hereinafter L group, must be sufficiently reactive for the perhydrolysis reaction to occur within the optimum time frame (e.g., a wash cycle). However, if L is too reactive, this activator will be difficult to stabilise for use in a bleaching composition.
• Suitable controlled release means can include confining the bleach to one portion of the composition.
• Another mechanism for controlling the rate of release of bleach may be by coating the bleach with a coating designed to provide the controlled release.
• the coating may therefore, for example, comprise a poorly water soluble material, or be a coating of sufficient thickness that the kinetics of dissolution of the thick coating provide the controlled rate of release.
• Additional protocols for providing the means of controlled release include the suitable choice of any other components of the composition such that when the composition is introduced to the wash solution the ionic strength environment therein provided enables the required controlled release kinetics to be achieved.
• Prefe ⁇ ed ligands include pyridine, pyridazine, pyrimidine, pyrazine, imidazole, pyrazole, and triazole rings.
• the prefe ⁇ ed cobalt catalyst of this type useful herein are cobalt pentaamine chloride salts having the formula [Co(NH 3 ) 5 Cl] Y y , and especially [Co(NH3) 5 Cl]Ci2.
• polyamine and modified polyamine compounds are useful herein including those derived from aspartic acid such as those disclosed in EP-A-0305282, EP-A-0305283 and EP-A-0351629.
• Prefe ⁇ ed dyes include SANDOLAN E-HRL 180% (tradename), SANDOLAN MILLING BLUE (tradename), TURQUOISE ACID BLUE (tradename) and SANDOLAN BRILLIANT GREEN (tradename) all available from Clariant UK, HEXACOL QUINOLINE YELLOW (tradename) and HEXACOL BRILLIANT BLUE (tradename) both available from Pointings, UK, ULTRA MARINE BLUE (tradename) available from Holliday or LEVAFIX TURQUISE BLUE EBA (tradename) available from Bayer, USA.
• the functional role of the silver coating agent is to form 'in use' a protective coating layer on any silverware components of the washload to which the compositions of the invention are being applied.
• the silver coating agent should hence have a high affinity for attachment to solid silver surfaces, particularly when present in as a component of an aqueous washing and bleaching solution with which the solid silver surfaces are being treated.
• the Mn (II) compound may be an inorganic salt in anhydrous, or any hydrated forms. Suitable salts include manganese sulphate, manganese carbonate, manganese phosphate, manganese nitrate, manganese acetate and manganese chloride.
• the Mn(II) compound may be a salt or complex of an organic fatty acid such as manganese acetate or manganese stearate.
