Definitions

• the present invention relates to a liquid water-containing agent for cleaning textile surfaces, which contains surfactants and organic solvents.
• carpets and upholstered furniture in particular are used as textile surfaces. These surfaces cannot, like other fabrics, e.g. Garments, soaked in washing baths or washed.
• cleaning agents are commercially available for cleaning them.
• stain removers which are applied in a highly concentrated form to the substrate to be cleaned in order to remove individual stains.
• carpet and upholstery cleaning agents which are applied in diluted form and removed again after a period of exposure.
• spray extraction process there are special devices with which the diluted agent can be applied over a large area to the substrate to be cleaned and can also be removed after the exposure time.
• the commercially available cleaning agents for cleaning textile surfaces are either aqueous solutions of surfactants and water-miscible organic solvents and, if appropriate, further constituents, or emulsions which, as essential constituents, are usually water, surfactants, water-miscible and water contain immiscible organic solvents.
• the emulsions are distinguished in particular by their cleaning action against lipophilic soiling.
• An optimal cleaning effect of these agents can, however, only be achieved if they are present as stable emulsions, which requires a precise coordination of the proportions of the individual components. Are the proportions such. B. changed by dilution with water, this breaks up into a 2-phase system.
• 1% dilutions of surfactant solutions in water are usually used. These agents usually do not contain any organic, water-immiscible solvents, since such large dilutions generally cannot give stable emulsions.
• the cleaning agents in the form of emulsions are usually so-called stain removers or pre-treatment agents. Due to the water-immiscible solvents contained therein, these agents are characterized u. a. with a good cleaning effect on lipophilic soiling. However, as already described above, it is not possible to dilute these agents in such a way that they can also be used for large-area carpet cleaning in conventional spray extraction processes or in carpet-pad processes, since the emulsions break up into two-phase systems.
• Another disadvantage of the commercially available agents as emulsions is that for their preparation the mixtures of the individual components for the preparation of the emulsions have to be heated because their phase inversion temperature is above room temperature. Heating is particularly problematic with low-boiling ingredients, since these can easily escape.
• a stain and stain remover contains water, liquid hydrocarbons, organic cosolvents, surfactants, and a non-sticky water-dispersible antisoiling agent.
• the agent described therein is preferably placed in an aerosol-type container using a conventional propellant, e.g. fluorinated hydrocarbon, bottled.
• the agent is used for the spot cleaning of stains from textile substrates.
• the agent described can not be used extensively in diluted form.
• the object of the present invention is to provide a cleaning agent for textile surfaces which is in the form of an emulsion and can be diluted as desired without the emulsion breaking, so as to meet the requirements for universal carpet and upholstery cleaning. Another object is to provide a means that can be produced at the lowest possible temperatures, so that even low-boiling ingredients without special precautions or safety measures can be incorporated.
• the agent according to the invention forms a stable microemulsion which can be diluted as desired with water without breaking into a multi-phase system.
• the agent according to the invention can be used in concentrated form or in dilution as a stain remover, as a pretreatment agent for carpet cleaning, in the carpet pad process or in the classic spray extraction process.
• Another object of the present invention is the use of the agent described above after dilution with water in a ratio of 1:10 to 1:50 in carpet cleaning using the spray extraction process.
• the diluted agent is applied over a large area to the substrate to be cleaned and also removed again after the exposure time, the application and removal of the agent usually being able to be carried out using the same device.
• Yet another object of the present invention is the use of the above-described agent in concentrated form or after dilution with water in a ratio of up to 1:10 for carpet cleaning using the carpet pad method.
• the agent is based on what is to be cleaned Substrate applied, usually sprayed on, and removed after an exposure time with a textile pad. A single-disc machine with a textile pad is usually used to remove the agent.
• the agent according to the invention is in the form of a microemulsion.
• the phase inversion temperature of the agent is usually below room temperature, so that it can be prepared at room temperature.
• the agent according to the invention is advantageously prepared by combining the individual components and stirring the mixture obtained at room temperature.
• the agent thus produced usually shows a transmission of 50 to 95%.
• the particle size is generally less than 120 nm.
• the agent obtained can be diluted as desired with water and used as a concentrate or diluted to a concentration of up to 0.5% by weight as a stable microemulsion.

• the C 12 -C 22 alcohol alkoxylates are nonionic surfactants with the formulas I or II R 1 O- (CH 2 CH 2 O) m -H (I), in which R 1 represents a saturated or unsaturated primary C 12 -C 22 alkyl group and m represents numbers from 1 to below 8, wherein R 2 and o can have the same meaning as R 1 and m in formula I and n stands for numbers from 0.5 to 2.
• 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 natural vegetable-based fatty alcohols 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 and palm kernel fatty alcohol or peanut fatty alcohol.
• C 12 -C 16 fatty alcohol ethoxylates are particularly preferably used.
• Oxo alcohol alkoxylates are also known compounds which can be obtained in a known manner by alkoxylation of oxo alcohols.

• 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 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.

• Suitable aliphatic hydrocarbons are, in particular, those with a chain length between 8 and 12 carbon atoms, with the isoaliphatic hydrocarbons being particularly preferred.
• Hydrocarbons with a chain length of less than 8 carbon atoms should not be used because they escape from the agent due to their low boiling point and are not available for the cleaning process.
• Hydrocarbons with chain lengths over 12 carbon atoms are also not particularly preferred, since they are solid at room temperature and are difficult to incorporate into the compositions.
• the agent according to the invention contains polymers which delay or prevent new contamination of the cleaned substrate, so-called antisoiling agents.
• Suitable polymers are (meth) acrylic acid and (meth) acrylate homo- and copolymers.

• the agents according to the invention can include ammonia or alkaline amines, e.g. Monoethanolamine. These compounds are added in particular to adjust the pH to a value between 8 and 10.
