Definitions

  • the present invention relates to a liquid water-based cleaning agent of textile surfaces, which contains surfactants and organic solvents.
  • the emulsions stand out for their organic content with water immiscible solvents especially due to their cleaning effect lipophilic stains. An optimal cleaning effect of this However, medium can only be achieved if they are present as stable emulsions, what an exact match of the quantitative ratios of each Components required. Are the proportions such. B. by dilution changed with water, it breaks up into a 2-phase system.
  • the cleaning agents present as an emulsion are usually so-called stain removers or pre-treatment agents. Because of that contained in water-immiscible solvents, these agents stand out u. a. with a good cleaning effect on lipophilic soiling. However, as already described above, it is not possible to dilute these agents that they can also be used for large-scale carpet cleaning in conventional spray extraction processes or can be used in carpet pad processes because the Break up emulsions into 2-phase systems.
  • Another disadvantage of the commercially available emulsions is that for their preparation, the mixtures of the individual components that are used for the production of the emulsions are necessary to be warmed because of their phase inversion temperature are above room temperature. Warming is especially low boiling ingredients problematic because they can easily escape.
  • the present invention has for its object a cleaning agent for To provide textile surfaces that are available as an emulsion and any can be thinned without breaking the emulsion, in order to meet the requirements for universal use Carpet and upholstery cleaning. Another job is to provide a means that at the lowest possible temperatures can be produced so that even low-boiling ingredients without special precautions or safety measures can be incorporated.
  • the agent according to the invention is a forms stable microemulsion, which can be diluted with water as desired, without in one break up multi-phase system.
  • the agent according to the invention can be in concentrated form or in dilution as a stain remover, as a pretreatment agent for carpet cleaning, in the carpet pad process or use in the classic spray extraction process.
  • Another object of the present invention is the use of the above described after dilution with water in one Ratio of 1:10 to 1:50 for carpet cleaning using the Spray extraction process.
  • the diluted agent is spread over a large area cleaning substrate applied and after the exposure time again removed, the application and removal of the agent usually with the same device can be performed.
  • Yet another object of the present invention is the use of the Agent described above in concentrated form or after dilution with water in a ratio up to 1:10 when cleaning carpets using the Carpet pad process.
  • the agent is based on what is to be cleaned Substrate applied, usually sprayed on, and after an exposure time removed with a textile pad. To remove the agent, use usually uses a single-disc machine with a textile pad underneath is.
  • the agent according to the invention is in the form of a microemulsion.
  • the phase inversion temperature the agent is usually below room temperature, so that it can be produced at room temperature.
  • the invention Means by combining the individual components and stirring the obtained Mixture prepared at room temperature.
  • the agent so produced shows usually a transmission of 50 to 95%.

  • the C 12 -C 22 alcohol alkoxylates can be obtained by alkoxylation of the primary C 12 -C 22 alcohols, in particular fatty alcohols with ethylene oxide (EO) and propylene oxide (PO).
  • Suitable fatty alcohols are, for example, the native fatty alcohols based on plants, such as lauryl alcohol, myristyl alcohol, cetyl alcohol, stearyl alcohol, behenyl alcohol, oleyl alcohol, elaidyl alcohol, ricinol alcohol, linoleyl alcohol, linolenyl alcohol and mixtures thereof, such as coconut fatty alcohol, palm alcohol and palm kernel fat.
  • C 12 -C 16 fatty alcohol ethoxylates are particularly preferably used.
  • Oxoalcohol alkoxylates are also known compounds which can be obtained in a known manner by alkoxylating oxoalcohols.
  • the oxo alcohols used are compounds made from petrochemical raw materials, e.g. B. can be obtained by Roelen's oxosynthesis.
  • Particularly preferred oxo alcohol alkoxylates are the ethoxylates of C 11 -C 13 oxo alcohols with a degree of ethoxylation of more than 10.
  • the alcohol alkoxylates and oxo alcohol alkoxylates are preferably used in a ratio of 1: 1 to 20: 1, particularly preferably from 5: 1 to 15: 1. Particularly stable microemulsions can be obtained in these mixing ratios.
  • the agent according to the invention usually contains from 1 to 15% by weight, particularly preferably from 3 to 10% by weight, based in each case on the finished agent, of C 12 -C 22 fatty alcohol alkoxylates and from 0.5 to 5% by weight, preferably 0.1 to 1% by weight, in each case based on the finished agent, oxo alcohol alkoxylates.
  • the agent according to the invention may further contain anionic surfactants as cleaning-active constituents.
  • Suitable anionic surfactants are, for example, C 8 -C 18 alkyl sulfates, C 8 -C 18 alkyl ether sulfates, C 8 -C 18 alkane sulfates, C 8 -C 18 ⁇ -olefin sulfonates, sulfonated C 8 -C 18 fatty acids C 1 - C 4 alkyl esters, C 6 -C 18 alkylbenzenesulfonates, sulfosuccinic acid mono- and di-C 8 -C 12 alkyl esters, C 8 -C 18 alkyl polyglycol ether carboxylates, C 8 -C 18 -N-acyl taurides, C 8 -C 18 -N-Sarcosinate and C 8 -C 18 alkyl isethionates.
  • the anionic surfactants can be present in amounts of up to 25% by weight, preferably 2.0 to 8.0 % By weight, based on the total agent, may be present.
