Definitions

  • the present invention relates to the use of laundry detergent compositions suitable for washing both white and coloured fabrics.
  • the compositions which contain a sequestrant, iminodisuccinate or hydroxyiminodisuccinate, in controlled amounts, have been found to give improved maintenance and/or restoration of colour fidelity during the wash.

  • Liquid detergent compositions may be prepared by admixing the essential and optional ingredients in any desired order to provide compositions containing the ingredients in the the requisite concentrations.
  • the colour benefit associated with the compositions used in the invention is twofold: protection (maintenance) of the colour or whiteness of new fabrics, and restoration (recovery) of the colour or whiteness of previously washed fabrics.
  • New fabrics when washed with the compositions used the invention, show reduced colour degradation as compared with fabrics washed in control formulations without IDS.
  • the fabrics maintain a new appearance even after multiple washing. This protection or maintenance benefit has been found to apply both to white and to coloured fabrics.
  • a cause of the colour degradation resulting from the laundry process may be heavy metal ions, especially iron but also copper, zinc and manganese: these may originate from the water or water pipes, from washing machine parts, from the detergent composition used, or from the soil present on the fabric.
  • the colour care benefit obtained according to the present invention may be attributed to the sequestration by the IDS of any heavy metal ions present in the wash liquor.
  • IDS nitrilotriacetate
  • the composition has a 0.25% aqueous solution pH (in demineralised water at 30°C) not exceeding 10.5, preferably not exceeding 10.0.
  • the preferred pH range is from 8.0 to 10.5, more preferably from 8.5 to 10.0.
  • a further subject of the invention is a process in which white or coloured fabrics are laundered using the composition of the invention.
  • the process is carried out in a wash liquor having a pH not exceeding 10.5, more preferably not exceeding 10.0.
  • the two preferred conditions previously mentioned - very low pH, and low sequestrant level - have especial relevance to the handwash as carried out, for example, in South East Asia. In that region, it is a common habit to presoak or prerinse the fabrics in water, without detergent, to remove gross soiling.
  • the wash liquor pH may be as low as 6.0 to 7.0.
  • the wet fabrics are then immersed in the main wash liquor (detergent solution).
  • the additional water imported into the wash liquor from the wet fabrics has the dual effect of diluting the wash liquor (and thus lowering the sequestrant level) and lowering the pH.
  • IDS has also been found to reduce the fading upon laundering of chlorine-sensitive dyes. This fading occurs due to the presence of sodium hypochlorite, which is routinely put into supply water for hygiene purposes: levels of 0.5 ppm are typical. This causes fading of dyes of a wide range of colours.
  • the incorporation of IDS in accordance with the present invention can significantly reduce the amount of fading attributable to chlorine in the wash water.
  • the sequestrants used were as follows:
  • the fabrics were washed in demineralised water containing copper ions (0.5 ppm Cu 2+ ex CuCl 2 ) at a liquor to cloth ratio of 200:1 in tergotometers for 30 minutes at 30°C at 90 rpm.
  • Colour changes were monitored as reflectances differences at 620 nm. Two different effects are in operation here: dye fading, which leads to a generally small reflectance increase; and dye darkening (colour degradation) resulting from the presence of the copper ions, leading to a rather larger reflectance decrease. Both effects are undesirable and result in deterioration of the appearance of the fabric.
  • the reflectance difference observed should be close to zero or a small increase (not greater than 3 units, and preferably not greater than 2 units).
