Definitions

  • This invention relates to fabric-washing detergent compositions which are especially designed for the washing of coloured or mixed coloured and white fabric loadings.
  • Hitherto fabric-washing detergent compositions of two types were available, i.e. (1) washing products of a non-bleaching type for coloured fabrics, which, although safe for the fabric dyes themselves, are not effective to prevent the tendency of some coloured fabrics to release into the wash liquor dyes which are then transferred during the washing process onto other fabrics being washed therewith; and (2) a bleach-containing fabric-washing product type which can inhibit dye transfer to a certain extent but at the same time will cause bleaching and fading of the colours of the fabrics.
  • washing products of a non-bleaching type for coloured fabrics which, although safe for the fabric dyes themselves, are not effective to prevent the tendency of some coloured fabrics to release into the wash liquor dyes which are then transferred during the washing process onto other fabrics being washed therewith
  • a bleach-containing fabric-washing product type which can inhibit dye transfer to a certain extent but at the same time will cause bleaching and fading of the colours of the fabrics.
  • dye-transfer-inhibiting compositions which comprise a peroxygen compound, e.g. an organic peroxyacid, combined with rather complex aldehyde or ketone compounds as bleach activator.
  • a peroxygen compound e.g. an organic peroxyacid
  • aldehyde or ketone compounds rather complex aldehyde or ketone compounds
  • compositions having dye-transfer inhibitory effects are disclosed in European Patent 0024367 (based on the activation of organic peracids with bromide ions) and European Patent Application 0024368 (based on a system comprising an organic peracid precursor and a bromide activator). Still, the main drawback of these compositions is that they too exert a rather strong direct fabric bleaching, tending to cause fading of the coloured fabrics.
  • European Patent Application 0058444 describes washing compositions useful for the reduction of dye transfer in fabric washing at lower temperatures, comprising a bleach system consisting essentially of an organic peracid or an organic peracid precursor in conjunction with a water-soluble iodide salt.
  • a bleach system consisting essentially of an organic peracid or an organic peracid precursor in conjunction with a water-soluble iodide salt.
  • iodide catalyst There are some snags in the use of iodide catalyst, i.e. 1) the risk of staining due to iodine formation and 2) the effect of direct fabric dye bleaching.
  • Heavy metals including copper have been proposed as catalyst for enhancing the decomposition or bleaching performance of peroxygen bleaching agents e.g. in EP-A-72166.
  • transition metal ions can catalyse dye bleaching in solution by oxygen bleaches. So hydrogen peroxide or hydrogen peroxide adducts, inorganic persalt/bleach activator systems and peroxyacids per se can all be activated by copper ions. However, it has been found that copper-catalysed peracid bleach systems were much more effective than copper-catalysed hydrogen peroxide systems (e.g. sodium perborate).
  • transition-metal-catalysed dye bleaching has only been achieved with transition metal ions which are easily capable of one-electron radox processes leading to the formation of reactive radicals.
  • transition metal ions which are easily capable of one-electron radox processes leading to the formation of reactive radicals.
  • Table I only copper and possibly cobalt gave catalysis of peracetic acid for dye bleaching, whereas all the other metals including chromium and zinc are inactive.
  • transition metal ions are well known to interact with peroxide compounds as in Route B above, thus inducing decomposition to radicals or radical species which are known to have high oxidation potential and are capable of oxidizing most unsaturated molecules, no other transition metals are as effective for dye transfer inhibition as copper.
  • Cupric ion being the smallest divalent transition metal ion, with the highest charge density, most readily forms stable complexes.
  • Cobalt III and chromium III complexes of dyes are also very stable, but apparently they are kinetically inert and, in contrast to copper, severe conditions are generally necessary to introduce cobalt III and chromium III into dye structures.
  • manganese which is known to be very useful for catalysing stain bleaching, especially with hydrogen peroxide bleaches in the presence of a carbonate, has proved to be ineffective for dye transfer inhibition. Experiments have even shown that under practical conditions manganese can inhibit the catalytic effect of copper, and so the presence of manganese ions in the system of the invention should preferably be avoided.
  • the invention provides a fabric washing detergent composition especially designed for washing mixed coloured fabrics comprising a surfactant, a detergency builder, a bleaching agent and a heavy metal compound, characterized in that it comprises as the bleaching agent an organic peracid or a peracid salt in an amount of 0.5 to 25% by weight and a hydrogen peroxide adduct in a molar ratio to said peracid or peracid salt of from 1:100 to 2:1, and as the heavy metal compound a Copper compound in an amount of from 0.002 to 2.5% by weight of Copper(11)-ion, said composition having a solution pH (5 g/I) of 7 to 11 and being free of a sequestrant which complexes more strongly with Copper than EDTA.
  • cupric ion concentration The influence of cupric ion concentration on an experiment of dye transfer inhibition is shown in the following Table 11 for the peracid bleaches monopersulphate, diperisophthalic acid and magnesium monoperphthalate, with and without sodium perborate.
  • the detergent base used in the experiments had the following composition:
  • CI Direct Red 81 (0.002 g/I), peracid (4.6x10 -4 g. atoms of active oxygen), pH stat. at 40°C.
  • the diperisophthalic acid used was a commercial product "Suprox®”; monopersulphate used was a commercial product "Oxone®”; and the peracetic acid used was pretreated with catalase to remove H 2 0 2 .
  • the apparatus consists of a Beckman @ DB spectrophotometer fitted with a 1 cm silica flow cell, a water bath to maintain the temperature of the bulk liquor and a pH stat to control the pH.
  • the cell is connected to the solution with small-bore silicon rubber tubing and the liquor is circulated by a Watson Marlow O flow inducer. This is fitted on the return tube from the cell to the bulk solution to prevent accidental flooding of the cell compartment.
  • the silicon rubber tubes enter the cell compartment of the spectrophotometer through small holes in the lid. The small amount of light which must enter here does not affect readings in the visible range.
  • the flow cell The flow cell
  • the silica flow cell has a path length of 1 cm. Its stopper has a glass entry tube almost reaching the bottom of the cell and set to one side out of the light path. A short exit tube takes the solution from the top of the cell through the pump and back to the bulk solution.
  • a 0.04% w/v stock solution of dye was diluted with demineralised water to give 250 ml of 0.004% solution. This was poured into a 600 ml beaker set in the water bath preheated to 40°C and the pH was adjusted. The solution was then pumped through the cell at a rate of 40 ml per minute. This gives a good flow through the cell without turbulence causing bubbles. The per cent transmission at ⁇ max for the dye was monitored on the recorder.
  • a further 250 ml of demineralised water containing 1.137x10- 4 moles of peracid was warmed to 40°C and the pH adjusted. This was added to the dye solution and the change in % transmission was recorded for one hour. During this time, the solution was stirred constantly and, at various time intervals, 50 ml aliquots were taken for titration with M/200 sodium thiosulphate.
  • Bleaches were compared at equal active oxygen concentrations.
  • the dye solution was scanned from 700 nm to 400 nm to find the maximum absorption wavelength. Then an absorption (at ⁇ max) vs concentration (% w/v) graph was plotted and the slope calculated.
  • Test fabrics with different dye types are used. One 17.5 cm x 17.5 cm square of dyed test cloth was used in each wash.
  • the sets of test cloths were washed in the Terg-0-Tometer for 30 minutes at a constant 40°C and 100 rpm.
  • the product concentration was 0.4% w/v in 18° hard water with a liquor to cloth ratio of 50: 1.
  • Each set of cloths was rinsed separately with three 600 ml portions of cold 18° hard water.
  • the sets of cloths from each pot were put into separate 600 ml portions of cold 18° hard water.
  • the rinses were then continued, each set of cloths being rinsed three times in 600 ml portions of cold 18° hard water.
  • the reflectance of the cloths was measured at the maximum absorbance wavelength of the dye using a Beckmann @ DB-GD grating spectrophotometer fitted with a diffuse reflectance attachment. Barium sulphate was used to standardise the instrument and as a reference when measuring the cloths.
  • composition of the invention should contain at least 0.002% by weight of copper, i.e. equivalent to about 0.1 ppm in solution, should have a 5 g/l solution pH of from 7 to 11, and should contain a hydrogen peroxide adduct at molar ratios to peracid which can be as low as 1:100 up to 2:1, most preferably from 1:25 to 1:1.
  • the upper limit of the copper concentration can be set at 2.5% by weight based on the total composition.
  • any copper(II) salt can be used in the practice of the invention, for example copper sulphate, copper carbonate, copper chloride, copper phosphate etc.
  • sequestration of copper by strong sequestrants should be minimized so as to favour dye/copper interaction and the production of radicals from the bleach, but on the other hand excessive bleach decomposition must be avoided during storage of the powder.
  • a relatively weak sequestrant such as ethylene diamine tetra-acetate (EDTA) can be tolerated in the present invention at levels usually below 0.2% by weight, preferably up to about 0.1% by weight, based on the total composition.
  • the level of sequestrant tolerated will depend on the level of copper added.
  • a higher level of copper in the formulation is required.
  • a preferred level of copper in such formulations will in general be at least about 0.02% by weight.
  • stain chromophores on fabrics which are generally quinonoid in character, are unlikely to behave very differently to dyes in bleaching reactions.
  • Dyes of different types e.g. azo, quinonoid and indigoid, have all been found to respond to transition metal ion catalysis in solution.
  • dyes can be bleached in solution (i.e. a homogeneous reaction)
  • the bleach in order to bleach dye on the cloth, the bleach must transfer from the solution phase into (or onto) the substrate phase.
  • a surprising feature of the present invention is that generally no positive catalysis of dye or stain bleaching on the fabric is observed from copper added to the wash solution.
  • the effect of copper in solution is likely to deplete the concentration of transferable bleach species (bleach anion ROO- and especially undissociated ROOH) in solution and thus to reduce the amount of bleach available to undergo phase transition into the dye or stain on the fabric, thus reducing direct fabric bleaching.
  • transferable bleach species bleach anion ROO- and especially undissociated ROOH
  • the organic peracids which can be used in the present invention are known in the art. They can be either aliphatic or aromatic and have the general formula: wherein R is an alkylene group containing from 1-16 carbon atoms or an arylene group containing from 6-8 carbon atoms and Y is hydrogen, halogen, alkyl, aryl or any group which provides an anionic moiety in aqueous solution, for example: wherein M is hydrogen or a water-soluble salt-forming cation.
