Definitions

  • the invention relates to a washing or cleaning agent which contains at least one rinse aid substance and at least one sulfur-containing amino acid, a process for the preparation of this detergent or cleaning agent and the use of the washing or cleaning agent as a machine for dishwashing.
  • Silverware corrodes on its surface as a result of reaction with constituents of the air and forms thin layers of the corrosion products. These layers cause interference colors or reduce the gloss of the silver surfaces.
  • the formation of the blackish, iridescent layers also takes place when the silverware is not in use and is usually referred to as "tarnishing" of the silver.
  • Silver can react here on substances containing sulfur, which are dissolved or dispersed in the rinsing water, because during cleaning of dishes in household dishwashers, food particles and thus u. a. Mustard, peas, egg and other sulfur-containing compounds introduced into the rinsing liquor. Also, the much higher temperatures during the mechanical rinsing and the longer contact times with the sulfur-containing food residues favor the tarnishing of silver in comparison to manual rinsing. The intensive cleaning process in the dishwasher also completely degreases the silver surface and makes it more sensitive to chemical influences.
  • active oxygen compounds such as sodium perborate or sodium percarbonate have been used as an alternative to the active chlorine compounds which serve to eliminate bleachable soils such as tea stains / tea stains, coffee stains, vegetable dyes, lipstick residues and the like.
  • active oxygen compounds are used together with bleach activators, especially in modern low-alkaline machine dishwashing detergents of the new generation of cleaners.
  • These modern compositions generally consist of the following functional components: builder component (complexing agent / disperging agent), alkali carrier, lead acid system (bleach + bleach activator), enzymes and wetting agents (surfactants).
  • the silver surfaces are fundamentally more sensitive to the changed formulation parameters of the new active chlorine-free cleaner generation with lowered pH values and activated oxygen bleaching. During the mechanical rinsing, these agents release the actually bleaching agent hydrogen peroxide or active oxygen during the cleaning cycle.
  • the bleaching effect of the active oxygen-containing cleaners is reinforced by bleach activators, so that a good bleaching effect is achieved even at low temperatures. In the presence of these bleach activators, peracetic acid forms as a reactive intermediate. Under these changed rinsing conditions, in the presence of silver, not only sulfide but also oxidic deposits on the silver surfaces are formed by the oxidative attack of the intermediately formed peroxides or of the active oxygen. Under high salt load additionally chloridic deposits can arise. The tarnishing of the silver is also reinforced by higher residual water hardness during the cleaning cycle.
  • British patent specification GB 1 131 738 discloses alkaline dishwashing detergents which contain benzotriazoles as corrosion inhibitors for silver.
  • US Pat. No. 3,549,539 describes highly alkaline, machine-usable dishwashing detergents which, as oxidizing agents, may contain, inter alia, perborate with an organic bleach activator. Additives of benzotriazole and iron (III) chloride are also recommended as anti-tarnish agents.
  • European patents EP 135 226 and EP 135 227 describe weakly alkaline machine dishwashing detergents containing peroxy compounds and activators which may contain benzotriazoles and fatty acids as silver protectants.
  • the application GB 1 400 444 describes granules which can be incorporated into surfactant powders and contain inter alia benzotriazoles as corrosion inhibitors.
  • benzotriazoles At higher water hardnesses (eg 21 ° dH), however, the anticorrosive effect of benzotriazoles is no longer sufficient. It comes to discoloration of the dishes and the formation of unsightly coverings. In addition, benzotriazoles tend to oxidize in the solid phase of detergent tablets and cause yellowing.
  • WO 96/41860 describes the preparation of an enzyme-containing granulate in which cystine is present as silver protection agent.
  • the enzyme granules can be used for the production of solid, in particular particulate cleaning agents.
  • WO 96/37596 discloses a dishwashing composition containing cystine as a silver protective agent.
  • WO 94/07891 describes the use of cysteine as a corrosion inhibitor in a mildly alkaline machine for dishwashing.
  • the agent should possess optimum washing and rinsing properties and should surpass the prior art agents in both washing and cleaning and silver corrosion protection.
