Definitions

  • the present invention relates to a washing, cleaning, aftertreatment or washing aid containing surfactant (s), silver and / or a silver compound and other conventional ingredients of detergents, cleaners, aftertreatment or washing aids. Furthermore, the invention relates to a process for the preparation of a washing, cleaning, aftertreatment or washing aid.
  • Antimicrobially active compositions and their use in washing, cleaning, aftertreatment or washing aids are known in the art.
  • the disinfectants used are halogen-containing substances or phenol derivatives or other aromatic hydrocarbons, which can be regarded as problematic for reasons of environmental compatibility.
  • Other, more compatible microbicides have only a limited spectrum of activity or are effective only under certain physical conditions.
  • Natural ingredients are also desirable.
  • Silver or silver ions have a blocking effect on thiol enzymes in microorganisms and thus have a high bactericidal and fungicidal action. In addition, silver has a germicidal effect.
  • washing, cleaning, aftertreatment or washing aids containing silver and / or silver ions are not stable, because the silver ions contained in the agents can be mixed with impurities, such as chloride ions to photosensitive silver chloride salts or sulfide to poorly soluble silver sulfide. Salts react. In a (strongly) alkaline medium, soluble silver ions can first react to AgOH and then further to sparingly soluble Ag 2 O. In addition to the poor solubility of these silver salts, in particular the silver oxides and silver sulfides cause considerable color changes despite small amounts, in particular a brown or black color, the liquid washing, cleaning, aftertreatment or washing aids.
  • the silver compound is selected from the group consisting of silver acetate, silver citrate, silver diamine chloride complex, silver cyclodextrin complex, silver dicyanokalium complex, silver phthalimide, silver phenylcyanamide, silver (ethylene thiourea) complex, silver imidazolate, transition metal NHC-calix [4] arene Complexes, silver crown ethers, silver nitrate and mixtures thereof.
  • the liquid washing, cleaning, after-treatment or washing aid particularly preferably contains silver nitrate.

  • the ratio of unneutralized fatty acid to elemental silver and / or the amount of silver cation is greater than or equal to 8 to 1. When setting this ratio, a particularly effective stabilization of the silver or the silver cation is achieved.
  • the amount of non-neutralized fatty acid is between 0.01 and 10 wt .-%, based on the total liquid washing, cleaning, aftertreatment or washing aid. This amount of unneutralized fatty acid achieves effective stabilization of the silver or silver cation. Excessive amounts of unneutralized fatty acid can result in undesirable clouding of the liquid agent since not all of the non-neutralized fatty acid in the agent can be dissolved.
  • the liquid washing, cleaning, aftertreatment or washing aid additionally contains 0.01 to 3 wt .-%, based on the total liquid washing, cleaning, aftertreatment or washing aid, ammonium hydroxide. Surprisingly, it has been found that particularly clear and thus aesthetically pleasing washing, cleaning, aftertreatment or washing aids are obtained by adding even small amounts of ammonium hydroxide.
  • Preferred liquid washing, cleaning, aftertreatment or washing aids contain the neutralized and unneutralized form of a fatty acid. With the help of the pH of the liquid washing, cleaning, aftertreatment or washing aid or by adding a pH adjuster can be prepared in a simple and fast way a stable, fatty acid soap and silver-containing washing, cleaning, aftertreatment or washing aid become.
  • liquid washing, cleaning, aftertreatment or washing aid is formulated as a fabric softener containing 0.5 to 50 wt .-% cationic surfactant.
  • Such fabric softeners according to the invention have the advantage that the items of laundry come into contact with the germ-reducing silver in a final treatment cycle of the washing machine, which further reduces the number of seeds on the surface of the items of laundry.
  • the agent itself reduces germs and prevents in this way the contamination of the fabric softener, which often manifests itself in unsightly black discoloration and deposit formation that arouses displeasure at the consumer.
  • the invention relates to the use of non-neutralized fatty acid for stabilizing silver-containing liquid washing, cleaning, aftertreatment or washing aids.
  • the liquid washing, cleaning, aftertreatment or washing aid contains silver and / or a silver compound.
  • silver is used either in elemental form or in the form of its compounds. If the silver used in elemental form, it preferably has particle sizes of 0.1 to 100 microns. Even finer particle sizes of silver can be achieved by using the elemental silver in colloidal form, wherein the silver has particle sizes of 0.001 to 0.1 microns.
  • the agent contains a silver compound and that silver compound is selected from the group consisting of silver acetate, silver citrate, silver diamine chloride complex, silver cyclodextrin complex, silver dicyanokalium complex, silver phthalimide, silver phenylcyanamide, silver (ethylene thiourea) complex, silver imidazolate, Transition metal NHC-calix [4] arene complexes, silver crown ethers, silver nitrate and mixtures thereof.

  • the liquid washing, cleaning, aftertreatment or washing aid contains non-neutralized fatty acid.
  • the amount of non-neutralized fatty acid in the washing, cleaning, aftertreatment or auxiliary washing agent also depends on the amount of silver or silver compound used. In general, the amount of non-neutralized fatty acid is in the range of 0.01% to 10%, preferably 0.1% to 5%, and more preferably 0.5 to 3% to obtain optimum stabilization at a minimum cost.
