Definitions

  • Liquid detergents are known in the art and have become increasingly popular with consumers in recent years because they offer a number of advantages over solid detergents. These include the simpler dosing and the generally faster dissolution in the wash liquor. In addition, they are often perceived as safer and less aggressive towards textiles and the environment.
  • Liquid detergents however, have the disadvantage that not all of the ingredients that are established in solid detergents and cleaning agents and that the user trusts in their performance, can be easily incorporated in a stable manner.
  • an effective bleaching system which in solid agents usually consists of a peroxidic bleach and a bleach activator that forms a peroxocarboxylic acid under perhydrolysis conditions, is problematic in liquid agents, because the stability of the bleach activator against hydrolytic attack is usually not adequately guaranteed, especially in aqueous agents can be.
  • the presence of oxidative bleaching agents can adversely affect the stability of other detergent and cleaning agent ingredients, such as dyes or fragrances or enzymes.
  • a further known embodiment of the separation principle consists in enveloping at least one of the problematic ingredients with a protective layer which surrounds the ingredient during the production and storage of the liquid agent and prevents contact with the negatively interacting other ingredients, but breaks open under application conditions and releases the ingredient , so that he can contribute the desired amount to the washing or cleaning result of the agent.
  • concentration differences between the liquid agent and the washing or cleaning liquid are used to dissolve the coating layer only under the conditions in which the agent is used.
  • the present invention uses targeted energy input in order to produce a reactive active ingredient from an ingredient that is stable when the liquid agent is stored.
  • the invention relates to a water and surfactant-containing liquid washing or cleaning agent which contains a hydrophobic precursor compound in microemulsified form, from which a peroxocarboxylic acid or its salt can be released by UV radiation.
  • Such precursor compounds are contained in the agents according to the invention preferably in amounts from 0.1% by weight to 20% by weight, in particular from 1% by weight to 15% by weight.
  • Another object of the invention is the use of a combination of an aqueous microemulsion of a hydrophobic precursor compound, from which a peroxocarboxylic acid or its salt can be released by UV radiation, and UV radiation for removing stains when washing textiles or when cleaning hard surfaces.
  • the microemulsion mentioned here can be a washing or cleaning agent according to the invention, but conventional components of washing and cleaning agents can also be missing;
  • the microemulsion used according to the invention preferably contains from 2% by weight to 12% by weight, in particular from 4% by weight to 10% by weight of the hydrophobic precursor compound, from 2% by weight to 40% by weight, in particular from 4% by weight to 35% by weight of microemulsifier and to 100% by weight of water.
  • Another object of the invention is a washing or cleaning process in which a textile surface in need of washing or a hard surface in need of cleaning is brought into contact with a surfactant-containing aqueous washing or cleaning liquid which contains a hydrophobic precursor compound in microemulsified form, from which UV- Irradiation a peroxocarboxylic acid or its salt can be released, and UV radiation can act on the liquid.

  • UV radiation can act on the liquid shortly before it is brought into contact with the object to be cleaned. It is preferred if the action of UV radiation takes place during the contact of the washing or cleaning liquid with the textile to be washed or the hard surface to be cleaned, the UV radiation not during the entire contact period, which is generally 1 minute to 2 Hours, in particular 2 minutes to 1 hour, must act, but the action can, if desired, begin even before the contact.
  • UV radiation is electromagnetic radiation, which comprises the wavelengths from 100 nm to 380 nm in the spectrum.
  • UV radiation is preferably used which has wavelengths in the range from 100 nm to 300 nm, in particular from 240 nm to 270 nm, it being further preferred if the maximum intensity of the UV radiation is in the range mentioned.

  • Peroxoesters of this type are commercially available under the name Luperox®.
  • Another advantage of the invention is that when such microemulsified hydrophobic precursor compounds are used, the stability of enzymes, for example proteases, in liquid media during storage is just as high as if the precursor compound were dispensed with, whereas the same use of H2O2 or phthalimidoperoxohexanoic acid instead Precursor compound leads to significant decreases in enzyme activity.
