Definitions

  • the present invention relates to detergent compositions comprising a pectate lyase and a bleach system selected from : a combination of a colour safe bleach booster and a peroxygen source, a metal bleach catalyst and/or a diacyl peroxide.
  • detergent compositions include nowadays a complex combination of active ingredients which fulfill certain specific needs.
  • current detergent formulations generally include surfactants and detergent enzymes providing cleaning and fabric care benefits.
  • stains stemming from plants, wood, mould-clay based soils, muddy soils, and fruits is one of today's toughest cleaning task; especially with the trend toward low wash temperatures.
  • These stains typically contain complex mixtures of fibrous material based mainly on carbohydrates and their derivatives : fibres and cell wall components.
  • Plant based soils are additionally accompanied with amylose, sugars and their derivatives.
  • Food soils are often difficult to remove effectively from a soiled substrate.
  • Highly coloured or "dried-on" soils derived from fruit and/or vegetable juices are particularly challenging to remove. Specific examples of such soils would include orange juice, tomato juice, banana, mango or broccoli soils.
  • pectin polymers are important constituents of plant cell walls.
  • Pectin is a hetero-poiysaccharide with a backbone composed of alternating homogalacturonan (smooth regions) and rhamnogalacturonan (hairy regions).
  • the smooth regions are linear polymers of 1 ,4-linked alpha-D-galacturonic acid.
  • the galacturonic acid residues can be methyl-esterified on the carboxyl group to a varying degree, usually in a non-random fashion with blocks of polygalacturonic acid being completely methyl-esterified.
  • the substrates on which pectin containing stains are commonly found can be fabrics, dishware or hard surfaces.
  • highly coloured or 'dried-on' soils derived for example, from fruit and/or vegetables are also particularly challenging soils to remove.
  • These coloured stains contain highly coloured compounds based on carotenoid compounds such as ⁇ -, ⁇ - and ⁇ -carotene and lycopene and xanthophyls (zeaxanthin or capsanthin), or porphyrins such as chlorophyll and flavonoid pigments and dye components.
  • This latter group of natural flavonoid based dye components comprises the highly coloured anthocyanins dyes and pigments based on pelargonidin, cyanidin, delphidin and their methyl esters and the antoxanthins.
  • Carotenoids soils are derived from carrots and tomatoes and in any processed products containing these components as well as certain tropical fruits and saffron. In particular in the dishwashing context, these coloured food soils may be removed from soiled articles into the wash solution, and then may be redeposited from the wash solution onto other articles in the wash or onto the interior of the dishwashing machine.
  • the problem is particularly noticeable when the wash load includes articles soiled by foods naturally containing significant levels of coloured dyestuff molecules, including for example tomato sauce and curry.
  • the Applicant has found that plastic articles in the wash, and especially areas of the interior of the dishwashing machine which are made of plastic material, are particularly susceptible to the staining/discoloration of the dishware by coloured food soils. Said soils can interact with the surface of such plastic substrates producing staining which can be very difficult to remove.
  • EP 692 947 provides an efficient dye transfer inhibiting composition for use in a machine dishwashing method.
  • the composition comprises an enzymatic system capable of generating hydrogen peroxide in combination with certain metallo catalysts.
  • EP 740 521 describes the use of diacyl and tetraacyl peroxide bleaching species for inhibiting the transfer of bleachable food soils and enhancing their removal from plastic substrates.
  • Bleaching compositions for the bleaching of such plant-, dirt based stains, highly coloured stains and soils and body soils have been extensively described in the art.
  • Suitable bleaching agents are usually percompounds which liberate hydrogen peroxide in aqueous solution, such as peroxyhydrates, perborate, percarbonate, perpyrophosphate, persilicate, urea peroxide and the like. It is know that the use of such percompounds can be improved by the use of organic bleach activators or peroxyacid precursors.
  • Such bleaching compositions are known to be effective in the removal of all sorts of stains. More recently, products containing bleach catalysts, particularly manganese bleach catalysts have become of interest.
  • oxygen bleaching agents have become increasingly popular in recent years in household and personal care products to facilitate stain and sou removal. Bleaches are particularly desirable for their stain-removing, dingy fabric cleanup, whitening and sanitization properties.
  • Oxygen bleaching agents have found particular acceptance in laundry products such as detergents, in automatic dishwashing products and in hard surface cleansers. Oxygen bleaching agents, however, are somewhat limited in their effectiveness. Some frequently encountered disadvantages include colour damage on fabrics and damage to laundry appliances, specifically rubber hoses these appliances may contain.
  • oxygen bleaching agents tend to be extremely temperature rate dependent. Thus, the colder the solution in which they are employed, the less effective the bleaching action. Temperatures in excess of 60°C are typically required for effectiveness of an oxygen bleaching agent in solution.
  • the need remains for a detergent compositions providing effective bleaching, especially of plant-, dirt based stains, highly coloured stains and soils and body soils.
  • Such need is even more accute in lower water temperatures and while providing improved colour-safety profiles and/or preventing the staining /discoloration of dishware by highly coloured components.
  • the detergent compositions of the present invention comprising a pectate lyase enzyme and a bleach system selected from : a combination of a bleach booster and a peroxygen source, a metal bleach catalyst and/or a diacyl peroxide. It has been surprisingly found that such selected bleach systems can maximise the pectate lyase enzyme cleaning efficiency.
  • detergent compositions comprising a pectate lyase and a such selected bleach system, provide superior cleaning due to the synergistic effect of the selected bleach system providing cleaning, stain removal and in a laundry context whiteness maintenance, and the pectate lyase degrading the pectin components of such soil and/or, in a laundry context, the pectin component of the fabrics that can bind such soils.
  • These selected bleach systems - enzyme mixed systems deliver an outstanding cleaning effect, especially on food coloured stains and body soils.
  • the compositions of the present invention provide synergistic whiteness maintenance.
  • the detergent compositions of the present invention comprising a diacyl peroxide, provide effective stain removal, especially on highly coloured stains and soils, especially on plasticware, and further prevent the staining / discoloration of the dishware by highly coloured components.
  • the combination of a pectate lyase with the bleach booster as the selected bleach system enhances cleaning by improving the overall efficiency of the bleach system, especially at low wash temperatures.
  • the addition of a bleach booster enables the oxygen- based bleaching system to more thoroughly bleach these exposed color bodies at low wash temperatures resulting in both improved stain removal and enhanced whiteness.
  • Pectin degrading enzymes are known to provide soil/stain removal benefits when used in washing and cleaning operations, specifically to provide the removal of a broad range of plant and fruit based stains and enhance the body soil cleaning profile of the detergent compositions.
  • pectin degrading enzyme it is meant herein any enzyme which acts to break down pectin substances and pectin related substances.
  • Pectin degrading enzymes can be classified according to their preferential substrate, highly methyl-esterified pectin or low methyl-esterified pectin and polygalacturonic acid (pectate), and their reaction mechanism, beta- elimination or hydrolysis.
  • Pectin degrading enzymes can be mainly endo-acting, cutting the polymer at random sites within the chain to give a mixture of oligomers, or they may be exo-acting, attacking from one end of the polymer and producing monomers or dimers.
  • pectinase activities acting on the smooth regions of pectin are included in the classification of enzymes provided by the Enzyme Nomenclature (1992) such as pectate lyase (EC 4.2.2.2), pectin lyase (EC 4.2.2.10), polygalacturonase (EC 3.2.1.15), exo-polygalacturonase (EC 3.2.1.67), exo-polygalacturonate lyase (EC 4.2.2.9) and exo-poly-alpha- galacturonosidase (EC 3.2.1.82).
  • the pectin degrading enzymes are natural mixtures of the above mentioned enzymatic activities.
  • pectin degrading enzyme has a unique profile of substrate specificity, activity and stability under different hardness, pH, temperature, surfactant and other detergent ingredient matrix conditions.
  • Pectin degrading enzymes are specifically directed to degrade pectin substances and in particular plant cell walls.
  • pectate lyase enzymes are directed to the cleavage of ⁇ -D-(1 ,4) glycosidic bonds in poly-D-galacturonans by the mechanism of ⁇ - elimination. These pectate lyase enzymes further help as well the removal of mixed stains / soils comprising pectin substances and other components.
