Definitions

  • the present invention is in the field of cleaning floors using aqueous surfactant solutions.
  • Processes that primarily aim to care for and preserve the flooring use agents that, after being applied and distributed on the flooring surfaces, produce more or less hard, protective films.
  • the agents usually contain heavy metal salts, mostly in emulsified form, waxes or film-forming polymers and crosslinking agents, which together form self-glossy or polishable films on the treated surfaces after drying. In this way, long-lasting preservation of the surfaces can be achieved, with strong mechanical loads being well tolerated, depending on the quality of the film.
  • a disadvantage of these agents is that removal of the firmly adhering films, if it becomes necessary, for example because of dirt or damage, is only possible under extreme conditions.
  • agents which contain high amounts of surfactants, often together with alkaline substances, organic solvents or abrasives. In many cases, these agents can be used to thoroughly remove dirt and old coverings, but the surfaces cleaned in this way are usually exposed to re-soiling without protection, unless a preservation treatment is connected.
  • the present invention offers a solution to this problem in the form of a method for cleaning floors, in which an aqueous surfactant solution in an amount of 0.2 to 5 g per square meter is applied undiluted to the floor, preferably by spraying, and is distributed there by wiping , wherein this solution contains a surfactant combination of alkyl polyglycoside and alkyl ether sulfate.
  • the process of spraying and in particular the subsequent wiping of the floor results in a largely uniform distribution of the cleaning agent, so that its effect can develop evenly.
  • the portion of the surfactant solution remaining on the floor after wiping dries on the floor surface so uniformly in an unprecedented manner that no streaks can be seen and the surface gloss remains intact.
  • the high cleaning effect and the property of streak-free drying are decisively determined by the surfactant combination of alkyl polyglycoside and alkyl ether sulfate present in the solution.
  • the alkyl polyglycosides used according to the invention are surfactants of the general formula I. RO (-G) n I in which R is a long-chain alkyl radical having 8 to 22 carbon atoms, G is a glycosidically bonded radical of a monosaccharide and n is a value between 1 and 10.
  • Alkyl polyglycosides have been known as surface-active substances for more than 50 years and can be produced in various ways. In this context, reference should only be made to European patent application 362 671, which also cites literature on older processes.
  • a synthesis which is important on an industrial scale today consists essentially in the acid-catalyzed condensation of monosaccharides of the aldose type (HO-G) with long-chain alcohols (R-OH) which contain 8 to 22, preferably 8 to 18, C atoms.
  • alkyl glycosides of the formula I When water escapes, alkyl glycosides of the formula I are formed RO (-G) n the value of n can be varied within wide limits by the choice of reaction conditions.
  • alkyl glycosides In the production of the alkyl glycosides, one can also start from oligosaccharides or polysaccharides, which are then depolymerized to lower fragments in the course of the acid-catalyzed reaction by hydrolysis and / or alcoholysis before the alkyl glycosides of the formula I form. Mixtures of different reducing monosaccharides or polysaccharides which contain different monosaccharide units can also be used as starting materials, and if n is greater than 1, appropriately mixed alkylglycoside molecules can be formed.
  • the following monosaccharides are preferably suitable as starting materials: glucose, mannose, galactose, arabinose, apiose, lyxose, gallose, old rose, Idose, ribose, xylose and talose, and the oligosaccharides and polysaccharides composed of these monosaccharides, for example maltose, lactose, maltotriose, hemicellulose, starch, partial hydrolysates of starch and sugar syrup.
  • alkyl glycosides are preferred which are composed of the same monosaccharide units. Alkyl glycosides in which the rest (-G) is derived from glucose are particularly preferred.
  • glucose, maltose, starch and other oligomers of glucose are used accordingly as starting materials.
  • the alkyl part R is derived from long-chain, optionally unsaturated, preferably primary alcohols which can be branched, but are preferably not branched.
  • Examples are the synthetic oxo alcohols with 9 to 15 C atoms and the fatty alcohols obtained from natural fatty acids with 8 - 22 C atoms.
  • the fatty alcohols with 8 to 18 carbon atoms and the oxo alcohols with 11 to 15 carbon atoms are preferred, but in particular the fatty alcohols with 8 to 10 carbon atoms or with 12 to 14 carbon atoms.
  • alkyl glycosides of formula I In addition to the actual alkyl glycosides of formula I, technically manufactured products generally also contain certain proportions of free alcohol R-OH and non-acetalized saccharides, optionally in oligomerized form. In most cases, these technical impurities do not interfere with the intended use. If alcohol mixtures are used in the production of the alkyl glycosides, for example alcohols based on natural fats, the alkyl glycosides are of course also mixtures with a correspondingly larger meaning of R in formula I.
  • the second component used in the surfactant mixture according to the invention is alkyl ether sulfate.
  • alkyl ether sulfate are salts of sulfuric acid monoesters of ethoxylated long-chain alcohols with the general formula II R'-O (-CH 2 -CH 2 -O) m -SO 4 M II
  • Alkyl ether sulfates have long been in practical use as surfactants, so that the preparation need not be discussed in more detail here.
  • a common method is the ethoxylation of long-chain alcohols R-OH with m mol of ethylene oxide and subsequent sulfation and neutralization.
  • the radical R ' is derived from long-chain, optionally unsaturated, preferably primary alcohols which can be branched, but are preferably not branched.
  • examples are the synthetic oxo alcohols with 9 to 15 carbon atoms and the fatty alcohols with 8 to 22 carbon atoms obtained from natural fatty acids.
  • Preferred within the scope of the invention are ether sulfates in which R 'is derived from fatty alcohols with 10 to 18 C atoms or from oxo alcohols with 11 to 15 C atoms.
  • the index m indicates the number of moles of ethylene oxide (EO) that are bound in the molecule.
  • m in the ether sulfates which can be used according to the invention is between 1 and 6, preferably between 2 and 4.
  • M represents the cation of the base used to neutralize the sulfuric acid half-ester.
  • M is preferably alkali metal or ammonium, in particular sodium.
  • the particular advantages of the cleaning process according to the invention are based to a very large extent on the simultaneous use of the alkyl polyglycosides and alkyl ether sulfates in the aqueous cleaning liquor.
  • the weight ratio between alkyl polyglycosides and alkyl ether sulfates is usually between about 1:10 and 10: 1. Weight ratios between 4: 1 and 1: 4 and in particular between 2: 1 and 1: 2 are preferred. Due to the particular interaction of these surfactants, the Cleaning solution required only a low concentration of the surfactant mixture, which is preferably 0.2 to 4 percent by weight and in particular 0.5 to 2 percent by weight.
  • the cleaning solution usually does not contain any other surfactants, albeit their Presence is not excluded, provided that it does not interfere with the advantageous effect of the mixture of alkyl polyglycosides and alkyl ether sulfates.
  • other cleaning agents and care products can be useful.
  • water-miscible organic solvents, complexing agents for water hardness, waxes and film-forming polymers should be mentioned.
  • dyes, fragrances, foam inhibitors and antimicrobial agents as well as acids and bases for regulating the pH are mentioned. It goes without saying that only representatives of these substances are selected in the selection which do not impair the advantageous effects of the surfactant mixture of alkyl polyglycosides and alkyl ether sulfates.
  • the water-miscible organic solvents which can be used according to the invention are primarily volatile alcohols and ether alcohols. Examples are in particular the lower alcohols with 2 to 4 carbon atoms, of which ethanol is particularly preferred.
  • the content of organic solvents in the cleaning agent solution is generally not more than 20 percent by weight, preferably between 1 and 10 percent by weight.
  • waxes and / or film-forming polymers in the cleaning agent solution has the purpose of making the thin film remaining on the floor surface more dirt-repellent and, if necessary, to compensate for minor damage to the surface of the floor which impair the gloss.
  • Suitable waxes are both synthetic waxes, such as polyethylene waxes, partially synthetic waxes, such as montan ester waxes, and natural waxes, such as carnauba wax and candelilla wax. According to the invention, natural waxes, in particular carnauba wax, are preferred.
  • the concentration of the waxes in the cleaning solution is usually not more than about 0.3 percent by weight, preferably between 0.05 and 0.2 percent by weight.
  • Suitable polymers are generally all polymer compounds which are soluble in water in the weakly alkaline range and which dry out from solutions with the formation of a film.
  • these are copolymers with a certain proportion of monomers containing carboxylic acid groups, in particular acrylic acid or methacrylic acid, which also contain nonionic monomers, in particular from the group of acrylic acid or methacrylic acid esters with lower alcohols and styrene.
  • the content of polymers in the cleaning agent solutions is usually not more than 0.3 percent by weight, preferably between 0.05 and 0.2 percent by weight.
  • Polymeric film formers and waxes can also be present at the same time.
  • the cleaning agent solution described above is applied in as uniform a form as possible to the floor to be treated and is then immediately distributed by wiping on the floor.
  • the application takes place in a particularly advantageous manner by spraying either with the aid of small hand-held sprayers or, particularly in the commercial sector, with the aid of mechanical spraying devices.
  • the amount to be applied depends within certain limits on the degree of soiling of the floor and its surface roughness. According to the invention, it lies in the range between 0.2 g and 5 g / m 2 and in particular between approximately 0.3 and 2 g / m 2 .
  • the wiping is preferably carried out with a damp, absorbent soft object, in particular with a cloth, a sponge or a mop.
  • the method according to the invention is also distinguished by ecological advantages.
  • the detergent solution directly to the surface of the floor to be cleaned, only the minimum amount necessary for cleaning is used, whereas with conventional wiping cleaning, the detergent was diluted in the water bucket, so that a large proportion of the wiping water always reached the sewage system unused .
