Definitions

  • This invention relates to detergent cleaning compositions especially adapted for use in automatic dishwashing machines.
  • phosphate or phosphate-free compositions which contain an oxygen bleach and enzymes, especially amylolytic and proteolytic enzymes, such as amylases and proteases.
  • the oxygen bleach is typically sodium perborate or sodium percarbonate which advantageously may be used in conjunction with an organic activator or bleach precursor, e.g. N, N, N', N'-tetraacetylethylene diamine (TAED), which upon dissolution will react to form an organic peroxyacid, e.g. peracetic acid, as the bleaching species.
  • an organic activator or bleach precursor e.g. N, N, N', N'-tetraacetylethylene diamine (TAED)
  • the starch removal properties of an automatic machine dishwashing composition containing a peroxygen bleach can be improved by incorporation of a dinuclear manganese complex.
  • products of this kind ofter also contain nonionic surfactants. When the amount of nonionic surfactant is relatively high, particularly at or above 1% by weight of the composition, the manganese complex causes discolouration of the product.
  • a first aspect of the present invention now provides an automatic machine dishwashing composition
  • a peroxygen bleach compound and a dinuclear manganese-complex having the general formula: wherein Mn is manganese which can individually be in the III or IV oxidation state; each x represents a coordinating or bridging species selected from the group consisting of H 2 O, O 2 2- , O 2- , OH - , HO 2 - , SH - , S 2- , >SO, Cl - , N 3- , SCN - , RCOO - , NH 2 - and NR 3 , with R being H, alkyl or aryl, (optionally substituted); L is a ligand which is an organic molecule containing a number of nitrogen atoms which coordinates via all or some of its nitrogen atoms to the manganese centres; z denotes the charge of the complex and is an integer which can
  • a second aspect of the present invention provides use of one or more nonionic surfactant components (a) as defined in the first aspect of the present invention for reducing discolouration in a composition comprising a peroxygen bleach compound and a dinuclear manganese complex as defined in the first aspect of the present invention.
  • the machine dishwashing composition is a mildly alkaline product having a solution pH below 12, e.g. from 8-12, preferably from 9-11.
  • the solution pH as meant here is the pH as determined from a solution of 3g/l of the compositions in distilled water.
  • Preferred manganese-complexes are those wherein x is either CH 3 COO - or O 2 or mixtures thereof, most preferably wherein the manganese is in the IV oxidation state and x is O 2- .
  • Preferred ligands are those which coordinate via three nitrogen atoms to one of the manganese centres, preferably being of a macrocyclic nature. Particularly preferred ligands are:
  • the type of counter-ion Y for charge neutrality is not critical for the activity of the complex and can be selected from, for example, any of the following counter-ions: chloride; sulphate; nitrate; methylsulphate; surfanctant anions, such as the long-chain alkylsulphates, alkylsulphonates, alkylbenzenesulphonates, tosylate, trifluoromethylsulphonate, perchlorate (ClO 4 - ), BPh 4 - , and PF 6 - ' though some counter-ions are more preferred than others for reasons of product property and safety.
  • the preferred manganese complexes useable in the present invention are:
  • compositions of the invention must contain at least 1%, preferably at least 2% by weight of nonionic surfactant. At least 50%, preferably at least 65%, optionally up to 90% or up t 100% by weight of the total nonionc surfactant must be selected from
  • nonionic surfactants of group (a) are present in the composition of the invention.
  • Preferred nonionic surfactants of group (a) include hydroxyalkyl glycolether surfactants having a melting point above 35°C, preferably above 40°C.
  • a preferred class of such materials has from 6 to 20, preferably from 8 to 14 carbon atoms in the alkyl chain thereof and from 15 to 50, preferably from 20 to 40 glycol ether units.

  • nonionic surfactants of this group are high melting point polyalkoxylated alcohols, optionally with the -OH group endcapped such as with an alkyl group and typically having an average of 10 to 20 alkyl groups and more than 30 alkylene oxide groups, eg ethylene oxide and/or proplylene oxide groups.
  • one or more other nonionics may be present in the amounts indicated by the foregoing.
  • These may includes any alkoxylated nonionic surface-active agent wherein the alkoxy moiety is selected from the group consisting of ethylene oxide, propylene oxide and mixtures thereof, is preferably used to improve the detergency and to suppress excessive foaming due to some protein soil.
  • nonionic surfactants for use in the invention are the low- to non-foaming ethoxylated strraightchain alcohols of the Plurafac® RA and LF series, supplied by the BASF, including Plurafac SLF 18B45; of the Lutensol® LF series, supplied by the BASF; of the Tritons DF series, supplied by the Rohm & Hass Company, and of the Synperonic® LF and NCA series, supplied by the ICI, Uniqema company.

Mixtures or two or more of such compounds may also be suitable. Particularly preferred is sodium percarbonate. However, sodium perborate, eg in the form sodium perborate monohydrate may also be used. Sodium perborate monohydrate is preferred to tetrahydrate because of its better storage stability while also dissolving very quickly in aqueous solutions. These bleaching agents may be utilied alone or in conjunction with a peroxyacid bleach precursor, such as TAED or any other bleach precursors known in the art, so long as it does not affect the starch-removing properties of the catalyst.
  • a peroxyacid bleach precursor such as TAED or any other bleach precursors known in the art
