Definitions

  • R is preferably H or methyl.
  • R and R 5 should not contain more than 18 carbon atoms total. Amide substituted bleach activator compounds of this type are described in EP-A-0170386.
  • the bleaching compositions of the invention are used in an aqueous solution.
  • the most preferred peroxy compound for use in such processes is hydrogen peroxide.
  • the pH of the aqueous peroxy solution is often adjusted with inorganic alkali metal basic materials, such as sodium hydroxide, sodium carbonate, sodium silicate and mixtures thereof.
  • the optimum pH lies somewhere between 7.5 to 12.5.
  • the pH is higher than about 12.5 the peroxy-compounds rapidly decompose so that it is difficult to control a proper bleaching rate without undue damage to the fibres.
  • the rate of bleaching in most cases is slow to the extent of being uneconomical for bleaching.
  • the C ⁇ -C. ⁇ alkyl ethoxysulfate salt comprises a primary alkyl ethoxysulfate which is derived from the condensation product of a C ⁇ -C ⁇ alcohol condensed with an average of from one to seven ethylene oxide groups, per mole.
  • Preferred are the C 12 -C l5 alkyl ethoxysulfate salts with an average of from one to five ethoxy groups per mole, and most preferably with an average of from one to three ethoxy groups per mole.
  • the C ⁇ .C ⁇ alcohol itself can be obtained from natural or synthetic sources.
  • R can be, for example, N-methyl, N- ethyl, N-propyl, N-isopropyl, N-butyl, N-2-hydroxy ethyl, or N-2-hydroxy propyl.
  • R 2 -CO-N ⁇ can be, for example, cocamide, stearamide, oleamide, lauramide, myristamide, capricamide, palmitamide, tallowamide, etc.
  • low-foaming nonionic surfactants especially the water soluble ethoxylated C 6 -C 16 fatty alcohols and C 6 -C 16 mixed ethoxylated/propoxylated fatty alcohols and mixtures thereof.
  • the ethoxylated fatty alcohols are the C 10 -C 16 ethoxylated fatty alcohols with a degree of ethoxylation of from 5 to 50, most preferably these are the C 12 -C 16 ethoxylated fatty alcohols with a degree of ethoxylation from 8 to 40.
  • ingredients can also be incorporated in a total amount of up to 50% by weight of the particulate, subject to the same conditions set out above for the inclusion of surfactants.
  • optional ingredients should preferably be solid at normal (ambient) temperatures, and should contain no more than 5% by weight of free (unbound) moisture, preferably less than 1%.
  • the aluminosilicate ion exchange materials are further characterised by their calcium ion exchange capacity, which is at least 200 mg equivalent of CaC0 3 water hardness/g of aluminosilicate, calculated on an anhydrous basis, and which generally is in the range of from 300 mg eq./g to 352 mg eq./g.
  • Polycarboxylates containing four carboxy groups include oxydisu ⁇ cinates disclosed in British Patent No. 1,261,829, 1,1,2,2-ethane tetracarboxylates, 1,1,3,3- propane tetracarboxylates and 1,1,2,3-propane tetracarboxylates.
  • Polycarboxylates containing sulfo substituents include the sulfosuccinate derivatives disclosed in British Patent Nos. 1,398,421 and 1,398,422 and in U.S. Patent No. 3,936,448, and the sulfonated pyrolysed citrates described in British Patent No. 1,439,000.
  • Silicates are useful components of automatic dishwashing detergent compositions incorporating the bleaching compositions of the present invention.
  • Suitable silicates include the water soluble sodium silicates with an Si0 2 : Na 2 0 ratio of from 1.0 to 2.8.
  • the silicates may be in the form of either the anhydrous salt or a hydrated salt.
  • Sodium silicate with an Sio 2 : Na 2 0 ratio of 2.0 is most preferred.
  • Silicates are present in the machine dishwashing detergent compositions at a level of from 5% to 50% by weight of the composition, more preferably from 10% to 40% by weight.
  • soluble silicates serve a variety of purposes in conventional laundry detergent formulations, their presence may be unnecessary in detergent compositions incorporating crystalline layered silicate material. However as the crystalline layered silicate, which forms part of the builder system of the detergent composition, must be added as a dry mix ingredient, soluble silicates may still be useful as structurants in the spray dried granules that normally form part of a laundry detergent composition. This is particularly desirable if the spray dried granule does not incorporate an aluminosilicate builder and would otherwise comprise only organic materials. Suitable silicates are those having an Si0 2 :Na 2 0 ratio in the range from 1.6 to 3.4, ratios from 2.0 to 2.8 being preferred.
  • the detergent compositions incorporating the bleaching compositions of the present invention will generally include an inorganic perhydrate salt, normally in the form of the sodium salt. Suitable inorganic perhydrate salts have been described herein before.
  • the bleaching composition will usually be incorporated to give a perhydrate level of from 3% to 40% by weight, more preferably from 5% to 30% by weight and most preferably from 10% to 25% by weight of the detergent composition.
  • the detergent compositions incorporating the bleaching compositions of the present invention will also generally include peroxyacid bleach precursors (bleach activators) . Suitable peroxyacid bleach precursors have been described hereinbefore.
  • Preferred enzymatic materials include the commercially available amylases, neutral and alkaline proteases, lipases, esterases and cellulases conventionally incorporated into detergent compositions. Suitable enzymes are discussed in US Patents 3,519,570 and 3,533,139.
  • Products comprising a laundry detergent composition enclosed in a bag or container are usually designed in such a way that container integrity is maintained in the dry state to prevent egress of the contents when dry, but are adapted for release of the container contents on exposure to a washing environment, normally on immersion in an aqueous solution.

Abstract

Une composition de blanchiment comprend du percarbonate de métal alcalin comme composé libérateur d'oxygène et des particules de carbonate ou de bicarbonate de métal alcalin d'une grosseur définie (grosseur particulaire moyenne de 250 νm ou supérieure), de préférence moins de 20 % des particules ont une grosseur inférieure à 250 νm, et moins de 5 % des particules ont une grosseur inférieure à 150 νm. La composition de blanchiment particulaire peut être un composant d'une composition pour machine à laver la vaisselle, une composition renforçant le blanchiment ou notamment une composition détergente pour blanchisserie. Le percarbonate a une stabilité à la conservation accrue dans les compositions de l'invention.
