Definitions

  • the present invention is in the field of machine dishwashing. More specifically, the invention encompasses automatic dishwashing detergents and their use in a dish washing process.
  • a consumer would use three products to wash dishes in an automatic dishwashing machine.
  • Salt would be added to the salt compartment to soften water.
  • a dishwashing detergent composition would serve to clean the articles, and a rinse aid would be used in the final steps of the dishwashing process to avoid streaks and smears on the articles.
  • "4 in 1" products comprise, in addition to the ingredients of the "3 in 1" products, a glass protection agent.
  • a builder generally serves to improve and extend the action of surfactant.
  • a builder may provide this contribution in a number of ways, e.g. by binding of calcium and magnesium ions, binding of transition metal ions, peptisation and suspension of soil in solution, provision of alkalinity and structuring/solubilising powder. The binding of calcium and magnesium is the most relevant function among these.
  • Suitable replacers include carbonate, citrate, zeolite, silicate and amino polycarboxylic compounds such as methylglycine diacetic acid (MGDA) and variants thereof e.g. NTA (nitrile triacetic acid), GDA (glutamic diacetic acid), DPA (dipicolinic acid) and IDS (imino disuccinic acid).
  • MGDA methylglycine diacetic acid
  • NTA nitrile triacetic acid
  • GDA glutmic diacetic acid
  • DPA dipicolinic acid
  • IDS amino disuccinic acid
  • citrate The most common replacer of phosphate builder is citrate.
  • a drawback of the inclusion of citrate is that its functionality is not optimal in a hard water environment. Natural water contains calcium and magnesium ions which can act as counterion to carbonate. Under certain conditions this may lead to the precipitation of calcium/magnesium carbonate. This precipitate is white on glass and washware and is certainly not desired by consumers. The level of these cations is referred to as the total hardness of water which is expressed as milligrams of equivalent calcium carbonate (Mw 100) per liter (ppm).Reference is made to L.S. Clesceri et al, Standard methods for the examination of water and wastewater, 17th edition, American Public Health Association, Washington DC, 1989 . The hardness of natural waters can range from only a few ppm up to over 400 ppm in some areas.
  • the invention relates to a multifunctional dishwashing composition for use in an automatic dish washer, said composition containing less than 1% phosphates, wherein the composition comprises
  • the invention further relates to a method for washing articles in a mechanical dishwashing machine comprising treating the articles with a wash liquor comprising the composition according to the invention.
  • the invention relates to the use of a composition according to the invention in an automatic dishwashing machine so no salt is required for rejuvenation of ion exchange material within the machine.
  • citrate or aminocarboxylic compound or another acid this is intended to encompass the acid, a salt thereof or a combination.
  • compositions according to the invention comprise a builder.
  • the compositions are essentially free of phosphate and therefore another builder is included.
  • essentially free of phosphate is defined as containing less than 1 wt% phosphate-compound on total weight of the composition.
  • phosphate containing compounds are tripolyphosphates, polyphosphates, hexametaphosphate, orthophosphate, and the alkalimetal (preferably sodium) salts thereof.
  • the builder functionality in these compositions is found in the combination of the amino polycarboxylic compound and citrate.
  • the amount of citrate is from 30 to 70 wt% on the total weight of citrate and amino polycarboxylic compound.
  • the amount of citrate is from 40 to 60 wt% on the total weight of citrate and amino polycarboxylic compound.
  • the total level of citrate in the compositions is preferably from 10 to 30 wt%, more preferred from 10 to 25 wt%.
  • the total level of amino polycarboxylic compound is preferably from 10 to 40 wt%, more preferred from 20 to 30 wt% on total weight of the composition.
  • Citrate is preferably present in the form of its sodium salt.
  • the amino polycarboxylic compound is selected fom MGDA and IDS.
  • the most preferred type of amino polycarboxylic compound is MGDA.
  • the composition comprises a further builder which may be selected for example from the group comprising alkali metal carbonates, bicarbonates, borates and zeolites.
  • the composition comprises from 0 to 5 wt% of silicate.
  • silicate is present in amounts up to 30 wt% or even higher, around 50 wt%. Purpose of the silicate in those known compositions is often to prevent fading of colours on glaze porcelain and decorated glasses via corrosion, as well as on enamel and metal corrosion.
  • the amount of silicate present in the composition of the current invention should be far less than 30 wt%, most preferably even as low as possible, while use of the machine dishwash detergent composition of the invention does not lead to negative effects from the reduction or even omission of silicate compounds in said composition.

  • silicium compounds in the form of silicate there is a maximum amount of silicium compounds in the form of silicate to be present.
  • the total amount of silicate present is 5 wt%. If any silicate is present in the composition or the process of the current invention, it is preferred that the silicate is chosen from the group of alkali metal silicates.
  • the silicate may provide pH adjusting capability and protection against corrosion of metals and against attack on décor on dishware, including fine china and glassware benefits.
  • the alkali metal silicate is hydrous, having from 15% to 25% water, more preferably, from 17% to 20%.
  • the silicate levels indicated in the specification are calculated as SiO 2 .
  • the highly alkali metasilicates can in principle be employed, but in general, yield too high a pH to be suitable for application in the compositions of the current invention. Therefore, the less alkaline hydrous alkali metal silicates having a SiO 2 :M 2 O ratio of from 2.0 to 2.4 are, greatly preferred. Anhydrous forms of the alkali metal silicates with a SiO 2 :M 2 O ratio of 2.0 or more are less preferred because they tend to be significantly less soluble than the hydrous alkali metal silicates having the ratio of less than 2.
  • alkali metal silicates sodium and potassium, and especially sodium, silicates are preferred.

Most preferred is a granular hydrous sodium silicate having a SiO 2 :Na 2 O ratio of 2.0, in particular for application in machine dishwash detergent compositions applied in powder or tablet form. While typical forms, i.e.
  • silicate particles powder and granular, of hydrous silicate particles are suitable, preferred silicate particles having a mean particle size between 300 and 900 ⁇ m and less than 40% smaller than 150 ⁇ m and less than 5% larger than 1700 ⁇ m. Particularly preferred is a silicate particle with a mean particle size between 400 and 700 ⁇ m with less than 20% smaller than 150 ⁇ m and less than 1% larger then 1700 ⁇ m.
  • Machine dishwash compositions according to the invention comprise less than 5 wt.% of silicate.
  • a maximum amount of 4 wt.% silicate further preferred an amount of less than 3 wt.%, more preferred of less than 2 wt.% is present.
  • Even better visible glass corrosion inhibition results are observed at slicate levels of less than 1.5 wt.%, more desirably less than 0.8 wt.%. Therefore, it is preferred that the level of silicate in the dishwash composition, more particularly, in the water of the wash cycle, is as low as possible. Accordingly, in a specific embodiment of the invention, the machine dishwash detergent composition is substantially free of silicate.
  • composition of the invention comprises a water soluble salt of bismuth.

  • composition of the current invention in any embodiment thereof, is substantially free of, and further preferred, does not comprise any aluminum or aluminum compound.
  • Aluminum ions are multivalent, and presence thereof in the composition will result in precipitation of insoluble salts thereof. This is disadvantageous as it will result in deposits on the glasware.
  • suitable surfactant systems for use in the machine dishwash detergent compositions of the current invention comprise ethoxylated and/or propoxylated nonionic surfactants, more preferably selected from nonionic ethoxylated / propoxylated fatty alcohol surfactants having a cloud point in water of 14 °C or less, preferably of 10 °C or less when used in the so called multifunctional systems.
