Definitions

  • the present invention relates to detergent compositions comprising a pectate lyase and a colour safe bleach booster.
  • 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-polysaccharide 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.
  • Bleaching compositions for the bleaching of such plant-, dirt based stains, highly colored 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 peroxy hydrates, 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. Oxygen bleaching agents have become increasingly popular in recent years in household and personal care products to facilitate stain and soil removal.
  • 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 color damage on fabrics and damage to laundry appliances, specifically rubber hoses these appliances may contain. In addition, 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 positively charged quaternary imine salts disclosed in these references when combined with peroxygen compounds, cause an unacceptable level of color damage on fabrics. Accordingly, the need remains for a detergent compositions providing effective bleaching, especially of plant-, dirt based stains, highly colored stains and soils and body soils, in lower water temperatures and while providing improved color- safety profiles.
