Definitions

  • a main wash detergent composition A main wash detergent composition
  • the invention relates to a phosphate-free main wash detergent composition
  • a phosphate-free main wash detergent composition comprising
  • main wash detergent compositions are based on a builder system consisting of, e.g., sodium carbonate and/or sodium bicarbonate, optionally in combination with silicates.
  • silicates are mainly insoluble, poorly soluble or slowly soluble silicates such as sodium aluminosilicate and metasilicate. Since the combination of soda and silicate generally gave rise to incrustation, the content thereof was reduced, while furthermore the use of anionic polymers was introduced. The latter also had a positive effect on the reduction of incrustation.
  • German patent application 38 25 858 discloses a phosphate-containing detergent composition having incorparated therein a metasilicate and an acrylic acid (co)polymer.
  • the invention therefore relates to a main wash detergent composition
  • a main wash detergent composition comprising
  • An essential component of the detergent composition according to the invention is formed by the soluble silicate preferably having a solubility of at least 2 g/1 in demiwater. The amount thereof is preferably at least 25 wt.%.
  • the soluble silicate has an Na2O/SiO2 ratio less than or equal to 1/2 and is preferably selected from the group consisting of disilicate, trisilicate and laminar silicate.
  • the detergent composition according to the invention also contains a polymeric component.
  • This polymeric component consists of at least one anionic polymer and has, in combination with the builder system based on soda and soluble silicate, the surprising effect that the incrustation is optimally reduced.
  • the detergent composition may also contain a phosphonate in another embodiment of the invention.
  • This phosphonate may be present in amounts of 0.1 to 5 wt.%, based on the weight of the detergent composition. Preferably, the content is not more than 1 wt.%.
  • the effect of the phosphonate is that the incrustation is reduced even more strongly, while also a bleaching agent optionally present is stabilised.
  • the detergent composition may also contain other conventional components such as filler, bleach system, enzyme, dye, optical brightener, perfume, hydrotrope, fabric softener, soap, antiredeposition agent etc.
  • the amounts and exact nature of these components are not critical.
  • the components conventional in detergent compositions may be used in normal amounts. In general, the amount of these components, with the exception of the filler and the water, range from 0.5 to 10 wt.%. If a filler is used, the amount thereof preferably ranges from 1 to 50 wt.%. Preferably, however, no filler is used. The amount of free water in the system is preferably kept as low as possible. Conventional amounts range from 0.1 to 5 wt.%.
  • the anionic polymer is used in an amount of from 0.5 to 10 wt.%.
  • the anionic polymer preferably used is a polymer with sulphonate groups, more in particular a polymer or copolymer of styrene sulphonic acid and/or vinyl sulphonic acid.
  • a polymer selected from the group of polymers and copolymers of acrylate, methacrylate and/or maleate is used in an amount of from 0.5 to 10 wt.%.
  • the washing-active component is preferably a non-ionic surfactant, e.g., selected from the group consisting of ethylene oxide and/or propylene oxide adducts of fatty alcohols, in combination with an anionic surfactant such as dodecyl benzenesulphonate and/or a fatty acid soap.
  • the amount of washing-active substance, i.e. the amount of anionic and non-ionic surfactant together is most preferably at least 10 wt.%, based on the weight of the detergent composition.
  • the detergent composition is most preferably in powdered form and obtained by spray-drying all or a portion of the components to an average particle size of from 0.1 to 2.0 mm, preferably to particles having an average size of from 0.3 to 1.4 mm.
  • the rest of the components can be atomized onto the spray-dried granules. It is also possible, however, to mix the components in dry condition, or to spray-dry a portion and to mix the resulting granules with the rest of the components.
  • the overall makeup of the detergent composition according to the invention is preferably:
  • the pH of the detergent composition according to the invention is preferably 10-12, as 1 wt.% solution in water having a hardness of 14° DH, preferably 10 to 11.
  • a powdered detergent composition having an average particle size of about 1.0 mm was manufactured by spraying the major part of the components, with the exception of the enzyme, the perfume and the perborate. These were added later.
  • the resulting product had the following composition:
  • This product was tested on laundry soiled in the household in a bundle test in comparison with the same amount (180 g) of regular main wash detergent composition on the basis of SAS (sodium aluminosilicate) and with the same amount of main wash detergent composition on the basis of STP (phosphate).
  • SAS sodium aluminosilicate
  • STP phosphate
  • a compact powdered detergent composition was manufactured by mixing the components.
  • the resulting product had the composition given in Table 2.
  • This detergent composition was tested in order to determine the degree of incrustation. On cotton the product showed an ash residue after clay test of 1.0%. On polyester cotton this was 1.4%.
