Abstract
Description
Technical Field
[0001] This invention relates to a detergent composition for washing dishes, preferably a detergent composition for automatic dishwashing.
[0002] The present invention also relates to the use of the dishwashing detergent composition of the present invention, preferably the automatic dishwashing detergent composition, in glass corrosion protection of glass dishwashing products. Background Technology
[0003] Glassware and baked glass cutlery are among the most frequently used items in a household, and therefore among the most frequently washed items in a dishwashing machine. Unfortunately, glassware sometimes doesn't get perfectly clean. Even with the best dishwashing machines, it's difficult to completely remove baking residue. Over time, the high temperatures of repeated washes in a dishwashing machine can cause hazy stains on delicate goblets and everyday glasses.
[0004] If consumers live in areas with hard water, deposits may gradually build up in their dishwashing machines. These mineral deposits, such as limescale, can adhere to glassware and tableware, causing them to appear cloudy.
[0005] However, even if consumers live in areas with soft water, glassware detergents still present problems. Soft water can corrode glassware over time, and this damage is irreversible. Glass corrosion can also be caused by long cycle times in the dishwasher, heat exposure, and poor glass quality. In short, the wear and tear of time will affect the glass surface of any glassware detergent.
[0006] Therefore, the problem of glassware corrosion during automatic dishwashing is well-known. It has been proposed that glassware corrosion is the result of two distinct phenomena.
[0007] First, corrosion is thought to be due to the leaching of minerals from the glass network, accompanied by the hydrolysis of the silicate network. Second, silicate materials are thought to be released from the glass.
[0008] These phenomena can damage glassware after multiple individual washing cycles. Damage may include haze, scratches, streaks, and other discoloration / harmful effects.
[0009] It has been proposed that silicate materials can effectively prevent the release of materials from glass compositions. However, the use of silicate compounds may have harmful side effects, such as a tendency to increase the separation of silicate materials from the glass surface.
[0010] A further solution is to use zinc, whether in metallic or compound form.
[0011] However, the use of soluble zinc compounds can cause harmful side effects, such as the development of precipitation of insoluble zinc compounds through interaction with other substances commonly present in dishwashing liquids.
[0012] This means that typically insoluble (or more precisely, slightly soluble) zinc compounds are preferred as zinc sources in dishwashing liquids. Because these zinc compounds have only low solubility in water, they are generally required to have relatively high surface areas (achieved through small particle sizes) in an attempt to achieve sufficient concentrations in water to obtain the desired glass corrosion prevention effect.
[0013] However, it has been found that using small particle sizes does not overcome the delivery problem, and the glass corrosion effect still exists even with these insoluble compounds.
[0014] It has been found that using zinc-containing glass and ceramics can solve the problem of glassware corrosion in dishwashing machines. Using zinc-containing ceramic / glass compositions overcomes the aforementioned problems of poor solubility / precipitation, while providing effective protection for the glassware.
[0015] However, the problem with zinc-containing ceramic / glass compositions (as well as water-soluble / insoluble zinc compounds) remains that these compositions do not perform satisfactorily in preventing corrosion of decorative glassware.
[0016] Glassware (and other ceramics, such as plates) can be decorated with glazes to apply patterns or designs to the glass / ceramic. Glazes typically contain a mixture of materials, similar to those used in glassmaking, and often also include metal oxides (such as lead oxide) / other compounds to give the glaze its color.
[0017] Glazes are typically applied to the glass during a second annealing firing, usually at a temperature lower than that used in glassmaking. It is generally accepted that lower firing temperatures result in glazes with lower resilience / higher sensitivity, such as to dishwashing conditions.
[0018] Even in the presence of zinc compounds, the glaze on decorative glassware / ceramic can still corrode. Glaze corrosion has the effect of removing some of the glaze from the glassware / ceramic after multiple dishwasher cycles. This glaze removal can cause the applied design to lose its luster and the colors to fade. Because glaze is typically used on high-quality glassware (such as handmade items), consumers who wash these products are reluctant to wash glazed items in a dishwasher. Manufacturers of glazed products are also reluctant to recommend using automatic dishwashers to clean these items. This may mean that consumers have no choice but to hand-wash such glazed glassware / ceramic.
[0019] Bismuth has been used as an additive to help prevent corrosion of glazed glassware.
[0020] However, the value of bismuth for this purpose is diminished by the detrimental effects of bismuth compounds on other components of the washing process. In this regard, bismuth has been found to discolor plastic materials. It also forms brown stains on unglazed glassware and cutlery. Furthermore, while the glazed portions of glassware may be protected, bismuth has been found to discolor the unglazed areas. For these reasons, the use of bismuth as a glaze protectant has been avoided.
[0021] Therefore, to date, there is still no ideal solution to provide glass corrosion protection for glass dishwashing products and / or decorative protection for glass and / or ceramic dishwashing products.
[0022] The purpose of this invention
[0023] In view of the prior art, one object of the present invention is to provide a dishwashing detergent composition, preferably an automatic dishwashing detergent composition, which should not exhibit any glass corrosion or any other optical defects, such as decorative damage, in the corresponding glassware. Summary of the Invention

Claim 15 relates to the use of such a dishwashing detergent composition of the invention, preferably an automatic dishwashing detergent composition, in glass corrosion protection of glassware and / or decorative protection of glass and / or ceramicware.
