Definitions

• the invention relates to a concentrate of a liquid cleaner.
• Modern detergents of all kinds usually contain surfactants which lower the interfacial tension.
• surfactants emulsification of immiscible liquids, e.g. ⁇ 1 in water, the wetting of solid surfaces with water and / or the stability of foams are favored.
• a classification of the surfactants is carried out after the loading of their hydrophilic molecule portion in anionic surfactants having negatively charged carboxylate - (- COO - ), sulfate - (- OSO 3 - ) or sulfonate groups ( - SO 3 - ).
• anionic surfactants having negatively charged carboxylate - (- COO - ), sulfate - (- OSO 3 - ) or sulfonate groups ( - SO 3 - ).
• these include the alkylbenzenesulfonates, the alkanesulfonates, the alkyl sulfates and the alkyl ether sulfates.
• Cationic surfactants not playing a role here and only mentioned for completeness, usually contain a quaternary ammonium group. They have significance as fabric softeners, anticorrosives, disinfectants or in the preparation of Pethumenemolsionen.
• nonionic surfactants which carry as hydrophilic molecular constituents Polether phenomenon introduced by ethoxylation in fatty alcohols, fatty alcohol ethoxylates.
• the nonionic surfactants are less sensitive to water hardness and have a low tendency to foam. However, as the temperature increases, the hydration of the polyether group and thus the solubility of nonionic surfactants decreases.
• amphoteric surfactants which contain anionic and cationic groups should be mentioned. Due to their good skin tolerance and antimicrobial effect, they are often used in cosmetics.
• wetting agents are surfactants that improve the wettability of solids by, in particular, aqueous liquids. Wetting agents reduce the surface tension of water and the interfacial tension between water and solids. As a result, the aqueous phase does not form individual droplets, but spreads out as a thin film, displacing air bubbles over the solid surface. They are therefore often added to cleaners.
• Sodium hydroxide is one of the most important chemical intermediates today.
• Caustic soda solutions are used primarily for adjusting pH values, in the preparation of sodium salts or dehydrochlorinations.
• caustic soda has become important in the production of soaps, detergents, viscose, cellulose, paper, as well as in water treatment and decomposition.
• Tetrapotassium pyrophosphate may be in liquid form or as granules. Tetrapotassium pyrophosphate is used not only as a retarding agent for cement and concrete, but also as a dispersant and as a builder for industrial cleaners.
• Sodium fatty alcohol ether sulfates are strong cleaning and wetting agents widely used in the industrial sector. They can be used in machine degreaser, in car wash products or typically as garage floor cleaner.
• the concentrate of a liquid cleaner according to the invention is based on the claim 1 that this 3.0- 8.0 wt.% Of an alkaline solution, 1.5-3.5 wt.% Of a mixture of anionic and nonionic surfactants, 1.75-2.75% by weight of a low-foaming wetting agent, 1.0-2.0% by weight tetrapotassium pyrophosphate, 0.5-1.5% by weight sodium fatty alcohol ether sulfate, dyes and / or fragrances and ad 100% by weight Has water.
• alkalis in a broader sense substances whose aqueous solutions show an alkaline reaction in which the concentration of hydroxide ions exceeds that of the hydrogen ions.
• this includes the hydroxides of the alkali and alkaline earth metals, ammonia water and the carbonates of the alkali metals to understand.
• the concentrate has, as alkaline solution, a sodium hydroxide solution of 45% by weight of NaOH in an amount of 3.0-5.0% by weight.
• alkaline solutions the aqueous solutions of sodium and potassium hydroxide
• concentrated solutions can be the various etching alkalis have a strong destructive effect on organic substances and attack heat and glass and many metals. Therefore, alkali-containing cleaning concentrates are often classified as highly dangerous.
• the concentrate contains, as alkaline solution, a calcined, technical, anhydrous sodium carbonate in an amount of 3.0-8% by weight.
• Anhydrous soda or sodium carbonate, Na 2 CO 3 is a white, hygroscopic salt whose solubility in water increases with increasing temperature up to 33.2 g in 100 g of solution.
• carbonate ions containing in aqueous solution cause a basic reaction, with solutions of mass fractions between 0.5 and 20%, a pH between 11.2 to 11.7 regularly adjusted.
• caustic soda or soda provides a good cleaning, inexpensive basic basis for the cleaning concentrate.
• an intensive foaming mixture provided with very good cleaning properties is preferably used.
• Such a surfactant mixture can be used advantageously dissolved in water, wherein the water content of this mixture between 45 wt.% And 55 wt.% Can lie. Accordingly, then about twice the stated wt.% Of the mixture of dissolved in water anionic and nonionic surfactants to use.
• the surfactant-water mixture should still have a pH of about 6.5.
• a further addition of 1.75 to 2.75% by weight of a low-foaming wetting agent takes place. It is especially thought of a sodium 2-ethylhexylsulfat. This wetting agent is highly effective, but low foaming for strongly alkaline, acidic and electrolyte-containing media. The hydrotropic properties are especially pronounced over the nonionic surfactants. In particular, alkaline metal degreasing can be ensured by this wetting agent.
• the ionicity is anionic and it is preferably the proportion of anionic substances in a solution in water about 42%, preferably the water content about 55%.
• the sodium sulfate content is about 1%.
• the pH should be about 9.
• the tetrapotassium pyrophosphate may be added as granules having a concentration of nearly 100%.
• the preferred amount of total system is 2% tetrapotassium pyrophosphate.
• the sodium fatty alcohol ether sulfate is preferably added dissolved in water, the water content between 65% by weight and 75% by weight, in particular by 70% by weight.
• anionic base material With a content of an anionic substance of, for example, 27%, sodium fatty alcohol ether sulfates or sodium laureth sulfates as anionic base material can be combined with anionic and nonionic surfactants.
• sodium laureth sulfates have good foaming power and are resistant to hardness.
• Diluted solutions can be thickened with fatty acid alkanolamides, special fatty alcohol ethoxylates or with electrolytes such as ammonium chloride or sodium chloride.
