Definitions

  • the present invention relates to an improvement in the rinse step of machine dishwashing operations.
  • the articles to be cleaned are first cleaned in a main wash step, and subsequently rinsed several times to rinse away any adhering main wash product and remaining soil. It is customary to add to the rinsing water a rinse aid composition which causes the articles to dry more evenly and improves the visual appearance of the articles when dry. Although such rinse aid compositions improve said visual appearance in comparison with articles which have not been rinsed with a rinse aid containing rinse liquor, said visual appearance may still need improvement, as, despite the use of a rinse aid, some film- and spot-formation may still occur.
  • the present invention therefore relates to an improved rinse step in a machine dishwashing operation, wherein the improvement comprises the use, in the rinse liquor, of an effective amount of a layered clay.
  • Rinsing of the cleaned articles with a rinse liquor which comprises such an effective am6unt of a layered clay reduces the formation of spots on the articles when dry.
  • the layered clay minerals suitable for use in the present invention belong to the geological classes of the smectites, the kaolins, the illites, the chlorites, the attapulgites and the mixed layer clays.
  • Typical examples of specific clays belonging to these classes are:
  • the layered clay minerals may be either naturally occurring or synthetic.
  • Preferred clay minerals for use in the present invention are natural or synthetic hectorites, montmorillonites and bentonites, and of these the hectorites are especially preferred.
  • Many of the above clays are commercially available, and typical examples of commercial hectorites are the Laponites ex Laporte Industries Ltd, England; Veegum Pro and Veegum F ex R. T. Vanderbilt, U.S.A.; the Barasyms, Macaloids and Propaloids ex Baroid Division, National Read Comp., U.S.A. (The above means are trade marks of the companies concerned).
  • Laponite S Laponite S
  • Laponite XLS Laponite RD
  • Laponite RDS Trade Mark
  • This is a synthetic hectorite having the following characteristics: analysis (dry basis) Si0 2 59.8%, MgO 27.2%, Na 2 0 4.4%, Li 2 0 0.8%, structural H 2 0 7.7%, with the addition of tetrasodium pyrophosphate (6%); specific gravity 2.53; bulk density 1.0.
  • the layered clay may be added to the rinse water as such, or it may be added thereto in the form of a liquid dispersion of the clay in water or in the form of a composition in any suitable physical form comprising the clay and other suitable or desirable ingredients.
  • Such other suitable ingredients may be low levels of wetting or detergent surfactants, organic acids, hydrotropes, alcohols, perfumes, germicides, anticorrosion agents, etc.
  • Suitable physical forms are powders, liquids, tablets, blocks, granulates, etc.
  • the level of the layered clay in the rinse liquor should be such that the rinse liquor contains from 0.001-1 g of the clay per litre.
  • the rinse liquor with the layered clay is effective at both higher and lower rinsing temperatures.
  • the normal programme was used, at a temperature of 65°C.
  • the water hardness was 9° German hardness.
  • a commercially available machine dishwashing product was used at a dosage of 3 g/I.
  • Example 1 The procedure of Example 1 was repeated, using another machine dishwashing product in the main wash step, and using in the rinse step either no rinse aid at all, or a commercially available rinse aid, or a rinse aid of the following formulation:
  • the dosage of the rinse aid was 2.5 ml in the rinse water (corresponding to 0.015 g/l of Laponite XLS).
  • the spot-formation results were as follows:
  • compositions according to the invention are suitable rinse aid compositions according to the invention:
