Definitions

  • the present disclosure relates to a dishwashing, preferably an automatic dishwashing, detergent composition.
  • the present disclosure also relates to the use of a dishwashing, preferably an automatic dishwashing, detergent composition for glass corrosion protection of glass dishwashing goods and/or for decor protection of glass and/or ceramic dishwashing goods.
  • the present disclosure further relates to the use of a quaternized hydroxy-Ci-C 8 -alkyl cellulose as a glass corrosion inhibitor for glass corrosion protection of glass dishwashing goods and/or for decor protection of glass and/or ceramic dishwashing goods.
  • a further solution has been to use zinc, either in metallic form or in the form of compounds.
  • the use of soluble zinc compounds can give rise to detrimental side effects, such as the development of a precipitate of insoluble zinc compounds formed by interaction with other species typically present in the dishwasher wash liquor.
  • Glassware and also other crockery such as plates may be decorated with a glaze to apply a pattern or design to the glassware I crockery.
  • the glaze typically comprises an admixture of materials, similar to the admixture used in glass preparation, usually further comprising a metal oxide (such as lead oxide) I other compound to give the glaze a colour.
  • the glaze is usually applied to the glass in a second annealing firing process, normally at a lower temperature than the glass firing process. It is recognised that the lower firing temperature provides the glaze with a lower resilience I higher sensitivity to, for example, dishwashing conditions.
  • the glaze of decorated glassware I crockery can still suffer from corrosion, even in the presence of a zinc compound. Glaze corrosion has the effect of removing a portion of the glaze from the glassware I crockery over a number of dishwasher cycles. The glaze removal has the effect that the applied patterns lose their shine and the pattern colours fade. As glazes are commonly used on premium glassware products, such as handmade items, consumers washing these products are wary of washing glazed items in a dishwasher. Glazed product manufacturers are also wary of recommending the use of automatic dishwashing for cleaning these products. This can mean that the consumer has no alternative but to wash such glazed glassware I crockery by hand.
  • Bismuth has been used as an additive to aid the prevention of corrosion of glazed glassware corrosion.
  • the value of bismuth in this purpose has been diminished by the detrimental effects that the use of bismuth compound has on other components of the washing process.
  • bismuth has been found to stain plastic materials.
  • Bismuth also causes the formation of a brown stain on non-decorated glassware and cutlery.
  • the glazed portion of the glassware may receive protection, bismuth has been found to stain the non-glazed portions. For these reasons the use of bismuth as a glaze protector has been avoided.
  • a dishwashing detergent composition preferably an automatic dishwashing detergent composition, characterized in that the detergent composition comprises at least a first glass corrosion inhibitor.

  • the present invention discloses a surprising technical advantage of quaternized hydroxy-Ci-C 8 -alkyl cellulose in a particular concentration window in dishwashing, preferably in automatic dishwashing (ADW), detergent compositions.
  • the quaternized hydroxy-Ci-C 8 - alkyl cellulose described herein is demonstrated to show surprising glass corrosion protection.
  • the quaternized hydroxy-C1-C8-alkyl cellulose is a quaternized hydroxy-ethyl cellulose or a quaternized hydroxy- propyl cellulose.
