Definitions

• the present invention relates to a water-based basic cleaner, which as an active Contains substances solvents and non-ionic surfactants.
• Basic cleaners are a special type of detergent that is one of a kind thorough cleaning of heavy soiling, e.g. in the industry, in the Kitchen and sanitary areas or for removing film layers on polymer and / or wax base is used.
• the basic cleaners are usually in a dilution of 1: 1 to 1:10.
• the basic cleaners also include the so-called universal basic cleaners, the have a pH value less than 10.5. They are due to their relatively low pH value also for use on more sensitive floor coverings, such as linoleum and rubber, suitable.
• These universal basic cleaners are a mixture of solvents, Surfactants, builders, solubilizers and volatile alkalis, either amines or ammonia.
• the builders are usually Phosphates, citrates, nitrilotriacetic acid (NTA), ethylenediaminetetraacetic acid (EDTA) and carbonates are used.
• NTA nitrilotriacetic acid
• EDTA ethylenediaminetetraacetic acid
• the known from the prior art Basic cleaners are available in a relatively large dilution because they are concentrated usually leads to separation of the solvents or salting out of the builders used fails. In U.S.
• Patent 5,342,551 describes a composition for removing film layers on floors, which contains monoethanolamine citrate, coupling agent and solvent, the pH between 8.0 and 10 by adding a sufficient amount of monoethanolamine or other alkaline agent.
• surfactants can the composition described e.g. Disodium isodecyl sulfosuccinate contain.
• the detergent composition described is only suitable for removing film layers on floors, thorough cleaning the removal of heavy soiling does not lead to satisfactory results.
• De DE-A-42 43 468 describes an aqueous cleaning agent which in undiluted state has a pH in the range between 5 and 9 and the 1 to 25 wt .-% of surfactant from the classes of nonionic and synthetic anionic surfactants and 0.1 to 12% by weight of alcohol from the Group benzyl alcohol, 2-phenoxyethanol, 2-phenylethanol and their mixtures contains.
• the detergent is used undiluted for cleaning hard Surfaces, after dilution with water in a weight ratio of 1: 3 to 1: 500 for cleaning textile coverings or hard surfaces.
• the usual universal basic cleaners usually have an active concentration of 20% by weight. These cleaners are, depending on the degree of contamination the surface to be cleaned, used in different dilutions. In the Development of new detergents is constantly striving to be means to develop, which have a higher performance and thus in lower Concentrations can be used.
• the object of the present invention was to provide a basic cleaner to provide its cleaning performance both at removal of old film layers on floors as well as when cleaning strong ones Soiling that exceeds that of conventional basic cleaners.
• the cleaning agent according to the invention a higher cleaning performance than that of conventional cleaners reached.
• the as Component A) solvent mixture called a significant improvement the cleaning performance as by the individual solvent components also as can be obtained by adding these individual effects.
• the basic cleaner contains a solvent mixture of a) phenoxy alcohol and b) a further alcohol selected from the group consisting of C 2 -C 4 alkyl glycols and ethers of C 1 -C 4 alcohols with (poly) glycols, in particular C 2 -C 4 glycols.
• Components a) and b) can be present in a ratio of 1: 0.5 to 1:10, preferably 1: 0.5 to 1: 2 and particularly preferably 0.9: 1 to 1: 0.9.

• the solvent components a) and b) can each be present in the inventive composition in amounts of 5 to 40% by weight, particularly preferably 5 to 30% by weight, based on the finished composition.
• the basic cleaner contains at least one nonionic surfactant from the group of the C 12 -C 22 alcohol alkoxylates, the end-capped C 12 -C 22 alcohol alkoxylates and the alkyl polyglycosides as further constituents.
• the C 12 -C 22 alcohol alkoxylates are nonionic surfactants of the formulas I or II R 1 O- (CH 2 CH 2 O) m -H wherein R 1 represents a saturated or unsaturated C 12 -C 22 alkyl group and m represents numbers from 1 to 20, 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.
