Definitions

  • the present invention relates to a machine dishwash detergent composition
  • a machine dishwash detergent composition comprising aminopolycarboxylic acid coordination complexes comprising one or more coordinate covalent bound iron-, cobalt- and/or manganese-cations.
  • Machine dishwash detergent compositions typically contain several different active components, including builders, surfactants, enzymes and bleaching agents.
  • Surfactants are employed to remove stains and soil and to disperse the released components into the cleaning liquid.
  • Enzymes help to remove stubborn stains of proteins, starch and lipids by hydrolyzing these components.
  • Bleach is used to remove stains by oxidizing the components that make up these stains.
  • 'builders' complexing agents
  • a machine dishwash detergent composition comprising:
  • composition • from 0.002 to 20 wt. % of free acid equivalent of aminopolycarboxylate comprising one or more coordinate covalent bound iron- (Fe), Manganese- (Mn) and/or cobalt- (Co) cations; wherein the composition comprises at most 1 wt. % of phosphate; and wherein the pH of a solution of 1 wt.% of the detergent composition in water as measured at 25 degrees Celsius is from 6.0 to 10.8.
  • aminopolycarboxylate comprising coordinate covalent bound Fe, Mn and/or Co cations can be effective in promoting bleaching stains in solution and on surfaces by having bleach catalyst activity. This is quite relevant since aminopolycarboxylates tend to be biodegradable and some, such as GLDA, are even made from renewable sources.
  • the invention relates to the use of aminopolycarboxylate comprising one or more coordinate covalent bound Fe, Mn and/or Co cations to provide a machine dishwash detergent composition with a bleach system having improved biodegradability.
  • Weight percentage is based on the total weight of the detergent composition unless otherwise indicated or as made clear from the context. It will be appreciated that the total weight amount of ingredients will not exceed 100 wt. %. Whenever an amount or concentration of a component is quantified herein, unless indicated otherwise, the quantified amount or quantified concentration relates to said component per se, even though it may be common practice to add such a component in the form of a solution or of a blend with one or more other ingredients. It is furthermore to be understood that the verb "to comprise” and its conjugations is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded.
  • indefinite article “a” or “an” does not exclude the possibility that more than one of the elements is present, unless the context clearly requires that there be one and only one of the elements.
  • the indefinite article “a” or “an” thus usually means “at least one”. Unless otherwise specified all measurements are taken at standard conditions. Whenever a parameter, such as a concentration or a ratio, is said to be less than a certain upper limit it should be understood that in the absence of a specified lower limit the lower limit for said parameter is 0.
  • Concentrations expressed in wt. % of ‘free acid equivalent’ refer to the concentration of the compound expressed as wt. %, assuming it would be in fully protonated from.
  • the following table shows how the free acid equivalent concentrations can be calculated for some (anhydrous) aminopolycarboxylates and (anhydrous) acid salts.
  • Preferably low-foaming nonionic surfactants are used particularly from the group of alkoxylated alcohols.
  • EO ethylene oxide
  • alcohol ethoxylates with linear residues prepared from alcohols of natural origin with 12 to 18 C atoms for example from coconut, palm, tallow fat or oleyl alcohol, and on average 2 to 8 mol of EO per mol of alcohol are preferred.
  • the preferred ethoxylated alcohols include for example C12-14 alcohols with 3 EO to 4 EO, C9-12 alcohol with 7 EO, C13-15 alcohols with 3 EO, 5 EO, 7 EO or 8 EO, C12-18 alcohols with 3 EO, 5 EO or 7 EO and mixtures of these, such as mixtures of C12-14 alcohol with 3 EO and C12-19 alcohol with 5 EO.
  • Preferred tallow fatty alcohols with more than 12 EO have from 60 to 100 EO, and more preferably from 70 to 90 EO.
  • Particularly preferred tallow fatty alcohols with more than 12 EO are tallow fatty alcohols with 80 EO.
  • Nonionic surfactants from the group of alkoxylated alcohols are likewise particularly preferentially used.
  • Preferably used nonionic surfactants originate from the groups comprising alkoxylated nonionic surfactants, in particular ethoxylated primary alcohols and mixtures of these surfactants with structurally complex surfactants such as polyoxypropylene/ polyoxyethylene/ polyoxypropylene (PO/EO/PO).
  • Such (PO/EO/PO) nonionic surfactants are furthermore distinguished by good foam control.
  • Aminopolycarboxylates are well known in the detergent industry and sometimes referred to as aminopolycarboxylic acids chelants. They are generally appreciated as being strong builders. Suitable aminopolycarboxylic acids include glutamic acid N,N- diacetic acid (GLDA), methylglycinediacetic acid (MGDA), ethylenediaminedisuccinic acid (EDDS), iminodisuccinic acid (IDS), iminodimalic acid (IDM), nitrilotriacetic acid (NTA), iminodiacetic acid (IDA), hydroxyethyliminodiacetic acid (HEIDA) aspartic acid diethoxysuccinic acid (AES) aspartic acid-N,N-diacetic acid (ASDA) , hydroxyethylenediaminetetraacetic acid (HEDTA), hydroxyethylethylene-diaminetriacetic acid (HEEDTA) , iminodifumaric (IDF), iminod
  • Preferred aminopolycarboxylates are GLDA, MGDA, EDDS, IDS, IDM or a mixture thereof, more preferred are GLDA, MGDA, EDDS or a mixture thereof and even more preferred are GLDA and MGDA or a mixture thereof.
  • GLDA is especially preferred as it can be made from bio-based materials (e.g. monosodium glutamate, which itself can be made as by-product from corn fermentation).
  • GLDA itself is highly biodegradable.
  • MGDA is more preferred in view of it being somewhat less hygroscopic, which improves detergent stability during storage.
  • Preferred salts are alkali-based salts and more preferred are sodium-based salts.
  • a coordinate covalent bond also known as a dative bond, dipolar bond, or coordinate bond is a type of two-centre, two-electron covalent bond in which the two electrons derive from the same atom.
  • the bonding of metal ions to ligands generally involves this type of bond.
  • the preferred method of manufacture aminopolycarboxylate coordination complexes comprising one or more iron- (Fe), Manganese- (Mn) and/or cobalt- (Co) cations comprises the following steps: a) providing an aqueous solution comprising aminopolycarboxylate and Fe, Mn and/or Co cations, wherein the molar ratio of the aminopolycarboxylate and the cations is from 100:1 to 1 :3; and b) optionally adjusting the pH of the aqueous solution to the range of from 6 to 11 ; and c) removing water from the aqueous solution to provide a composition comprising aminopolycarboxylate with coordinate covalent bound Fe, Mn and/or Co cations and the composition having water content of at most 60 wt.% and/or precipitating the complexes from aqueous solution by adding a non-aqueous solvent (preferably an organic solvent such as ethanol).
  • a non-aqueous solvent preferably an organic solvent such
  • step c) water is removed until a solid is provided or a precipitated solid formed on addition of an organic solvent is separated from the supernatant solution by filtration and then air dried.

  • the molar ratio of aminopolycarboxylate and the cations can be from 100:1 to 1 :3. Lower ratios will lead to only a part of the aminopolycarboxyate comprising coordinate covalent bound Fe, Mn and/or Co ions. This can be beneficial since such an aminopolycarboxylate mixture can both contribute to effective bleaching as well as providing strong builder and chelating functionality in one go. Higher ratios are beneficial to provide a more targeted bleach catalyst activity and can allow for more than one Fe, Mn and/or Co cation to be coordinate covalent bound to the aminopolycarboxylate. In this respect it is noted that many aminopolycarboxylates are capable of coordinate covalent binding more than one Fe, Mn and/or Co cations.
  • Preferred coordination complexes include Mn" (GLDA) 2- , Mn” 2 (GLDA), Fe IH (GLDA)", Fe IH (GLDA) (OH) 2 ; Fe IH (GLDA) (OH) 2 3 Co” (GLDA) 2 ", Co” 2 (GLDA), Co 1 " (GLDA)", Co 1 " (GLDA) (OH) 2 ; Co 1 " (GLDA) (OH) 2 3 ’ Mn” (MGDA)", Fe 1 " (MGDA), Co” (MGDA)", Co 1 " (MGDA), Mn” (EDDS) 2 ; Fe 1 " (EDDS)”, Co” (EDDS) 2 ; Co 1 " (EDDS).
