Definitions
- This invention relates to machine dishwashing compositions.
- the invention relates to improved phosphate-free machine dishwashing compositions comprising a polyamino acid.
- Scale formation on dishes and machine parts is thus an important problem with phosphate-free machine dishwashing products, especially if they are used in hard water areas and/or if the builder system comprises sodium carbonate and/or if the bleach system comprises sodium percarbonate.
- the invention provides a phosphate-free machine dishwashing composition
- a non-phosphate builder wherein the amount of carbonate and/or bicarbonate builder if present does not exceed 50% by weight of the composition, and containing at least more than 1%, preferably at least 2% up to 10% by weight of a poly-amino acid compound of the formula: poly (X) n wherein X is independently aspartic acid or salts thereof, glutamic acid or salts thereof, glutamine, asparagine, or mixtures thereof, and n is 3 to 1000, preferably from 3 to 500.
- the X amino acids may be entirely comprised of any one of the X group i.e. polyaspartates, polyglutamates, polyglutamines, polyasparagines, or they may be any combination of members of the group, e.g. poly (Asp)5(Glu)5.
- Builder materials are well-known in the art and many types of organic and inorganic compounds have been described in literature. They are normally used in all sorts of cleaning compositions to provide alkalinity and buffering capacity, prevent flocculation, maintain ionic strength, extract metals from soils and/or remove alkaline-earth metal ions from washing solutions.
- the builder material usable herein can be any one or mixture of the various non-phosphate builder materials, such as for example the alkalimetal citrates, carbonates and bicarbonates; nitrilotriacetic acid (NTA); dipicolinic acid (DPA); oxydisuccinic acid (ODS); alkenylsuccinates (AKS); and zeolites. They may be present in the composition of the invention in an amount as low as 5% up to about 90% by weight, preferably from 10% to 80% by weight.
- Particularly preferred builders are citrates, alkenylsuccinates, carbonates, bicarbonates, zeolites, and mixtures thereof.
- a carbonate and/or bicarbonate builder either alone or in admixture with other builders it should however be observed that the amounts thereof should not exceed 50% by weight of the composition, as explained above.
- compositions containing carbonate and/or bicarbonate builder in an amount of 0% up to 40% by weight are preferred.
- Surfactants though not strictly essential may also be present for detergency, soil removal, foam depression and/or as rinse aids. If present they can be used in an amount of up to about 60% by weight depending upon their type and properties. Normally in a properly built or highly built composition as is conventional, only small amounts of low-to non-foaming nonionic surfactant in the order of 0.1-5% by weight are preferably used, to aid detergency and particularly to suppress excessive foaming caused by some protein soil. Higher amounts i.e.
- highly detersive surfactants such as the high HLB nonionic surfactants, the anionic sulphate or sulphonate surfactants and the alkyl polyglycoside class of surfactants, may be used in normally lower builder containing active-based compositions.
- composition of the invention may and preferably further contains one or more of the following specialized components for specific purposes during the multi-step wash cycle typical for machine dishwashing compositions:
- Alkalimetal silicate preferably sodium silicate at a level of from about 1 to about 40% by weight, preferably from 5 to 35% by weight.
- This material is employed as a cleaning ingredient, source of alkalinity, metal corrosion inhibitor and protector of glaze on china tableware.
- sodium silicate having a mol ratio of SiO2:Na2O of from about 1.0 to about 3.3., preferably from about 1.8 to about 2.5, normally referred to as sodium disilicate.
- Bleach system If present the amount will preferably lie in a range from 1 to 30% by weight.
- Alkali metal hypochlorite may be incorporated in liquid compositions.
- Other chlorine bleaches which may be incorporated are alkali metal salts of di- and tri-chloro and di- and tri-bromo cyanuric acids.
- Preferred bleaches are the peroxygen bleaches, such as sodium perborate (tetra- or monohydrate) or sodium percarbonate. These are preferably used in conjunction with a bleach activator which allows the liberation of active oxygen species at a lower temperature. Numerous examples of activators of this type, often also referred to as bleach or peracid precursors, are known in the art.
- Preferred bleach activators are tetraacetyl ethylene diamine (TAED), glucose pentaacetate (GPA) and the mono-long chain acyl tetraacetyl glucoses as disclosed in WO 91/10719, but other activators such as choline sulphophenylcarbonate (CSPC) as disclosed in US Patents 4,751,015 and 4,818,426 can be used.
- TAED tetraacetyl ethylene diamine
- GPA glucose pentaacetate
- CSPC choline sulphophenylcarbonate
- the amounts of sodium perborate or percarbonate and bleach activator in the compositions preferably do not exceed 20% and 10% by weight respectively.
- peroxygen bleach is potassium monopersulphate.
- Further peroxygen bleaches which may be used are the organic peroxyacids and their metal salts. Typical peroxyacids include:
- Enzymes - Amylolytic and proteolytic enzymes are normally used.
- the amylolytic enzymes usable herein can be those derived from bacteria or fungi.
- Preferred amylolytic enzymes are those prepared and described in GB Patent No. 1,296,839, cultivated from the strains of Bacillus licheniformis NCIB 8061, NCIB 8059, ATCC 6334, ATCC 6598, ATCC 11945, ATCC 8480 and ATCC 9945 A.
- Examples of such amylolytic enzymes are those produced and distributed under the Trade-names of SP-95® and Termanyl® by Novo Industri A/S, Copenhagen, Denmark.
- amylolytic enzymes are generally presented as granules and may have enzyme activities of from about 2 to 10 Maltose units/milligram. They may be present in the composition of the invention in amounts such that the final composition has amylolytic enzyme activity of from 103 to 106 Maltose Units/Kilogram.
- amylolytic activity as referred to herein can be determined by the method as described by P. Bernfeld in "Method of Enzymology” Volume I (1955) page 149.
- the proteolytic enzymes usable herein are for example the subtilisins which are obtained from particular strains of B. Subtilis and B. licheniformis, such as the commercially available substilisins Maxatase® supplied by Gist-Brocades NV, Delft, Holland, and Alcalase®, supplied by NOVO Industri A/S Copenhagen, Denmark. Particularly suitable are proteases obtained from a strain of Bacillus having maximum activity throughout the pH range of 8-12, being commercially available from NOVO Industri A/S under the Trade names of Esperase® and Savinase®. The preparation of these and analogues enzymes is described in GB Patent No. 1,243,784.
- proteolytic enzymes may be present in amounts such that the final composition has proteolytic enzyme activity of from about 106 to 108 Glycine Units/Kilogram.
