Definitions

  • the present invention relates to a method for cleaning solid surfaces, in particular fittings in bathrooms and similar rooms.
  • foam cleaners are increasingly used today.
  • the use of the cleaning agent in the form of a foam has the advantage that, due to the better adhesion of the foam to the surfaces, even vertical and sloping surfaces can be evenly provided with cleaning agent without the cleaning agent running off these surfaces immediately.
  • the foam is generally generated immediately when the cleaning liquid is sprayed onto the surfaces with the aid of suitable devices: in the case of hand-operated foam spray pumps, the liquid emerging from the spray nozzle is mixed with air in such a way that it hits the surface as foam; in aerosol products, the propellant gas is used to generate the foam.
  • foam preparations have already been proposed for this cleaning process, there are still a number of problems with this process that are still unsolved.
  • many preparations require a thorough rinsing with water and dry wiping to prevent residues of the cleaning agents from remaining visible on high-gloss surfaces, for example mirrors, tiled surfaces or chrome surfaces.
  • the causes are the lack of uniformity and the lack of transparency of the detergent residues.
  • Another problem in modern bathrooms is the cleaning of numerous plastic objects, such as bathtubs, shower cubicles or fittings.
  • the object of the present invention was therefore to develop an overall more suitable cleaning method which, in particular, does not have the disadvantages mentioned above.
  • the invention relates to a method for cleaning bathroom fittings and other solid surfaces with cleaning foam, in which the foam is generated from an aqueous liquid which contains an alkyl polyglycoside as an essential surfactant.
  • the aqueous solution preferably additionally contains small amounts of monohydric alcohols having 2 to 3 carbon atoms, in particular ethanol.
  • the new cleaning process is characterized by a good cleaning effect even on vertical surfaces and leaves even, if not rinsed or polished, even and completely transparent residues that are practically invisible even on high-gloss surfaces.
  • the aqueous surfactant solution used foams up easily and provides very stable foams which are practically non-flammable even when propane / butane is used as an aerosol propellant.
  • the alkyl polyglycosides used as surfactants in the aqueous liquid are compounds 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 EP-A-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 preparation of the alkyl glycosides, it is also possible to 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, altrose, idose, ribose, xylose and talose as well as the oligo- and polysaccharides composed of these monosaccharides, for example maltose, lactose, maltotriose, hemicellulose , Starch, partial hydrolyzates of starch and sugar syrup.
  • alkyl glycosides are preferred which are composed of the same monosaccharide units. Alkyl glycosides in which the rest (-G) from which glucose is derived.
  • 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, industrially 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 cleaning liquids used in the process according to the invention can contain further surfactants, provided that the advantageous effects of the process are not impaired thereby.
  • surfactants are, in particular, anionic surfactants, of which long-chain alkyl sulfates should be mentioned in particular. They are preferably used as sodium salts. Fatty alcohol sulfates with about 12 carbon atoms in the alkyl chain are particularly preferred.
  • the total content of surfactants in the aqueous liquid used according to the invention is preferably between approximately 1% and approximately 6% by weight, in particular between approximately 2 and approximately 4% by weight.
  • the aqueous liquids used according to the invention can contain monohydric alcohols with 2 to 3 carbon atoms, that is to say ethanol, n-propanol and isopropanol, of which in turn ethanol is particularly preferred.
  • the alcohol content in the aqueous liquid is preferably between 0.5 and 12% by weight and is in particular between about 1 and 5% by weight.
  • the addition of the alcohols improves the cleaning result on certain soils in the process according to the invention without promoting stress corrosion corrosion on plastic surfaces and without increasing the flammability of the foams.
  • An overall particularly favorable result is obtained when the weight ratio of surfactant to alcohol in the solution is between about 1: 1.5 and about 2: 1.
  • the aqueous liquids used according to the invention can contain small amounts of other active ingredients and additives, as are customary in sanitary cleaners of this type. If such auxiliary substances and additives are also used, it is of course a prerequisite that these substances do not impair the positive results obtained with the process according to the invention.
  • active ingredients are lime-dissolving organic acids, such as citric acid, acetic acid or lactic acid or their water-soluble salts, which are preferably present in amounts of 2 to 6% by weight, based on the total aqueous liquid.
  • the pH of the aqueous liquid can be slightly acidic to weakly alkaline and is preferably between about 4 and about 9.
  • auxiliaries and additives are dyes, corrosion inhibitors, antimicrobial agents or preservatives and perfume.
  • the aqueous liquids used according to the invention preferably contain no polyhydric alcohols and no nonionic surfactants of the alcohol ethoxylate type.
  • foam is preferably generated directly when the liquid emerges from the sprayers.
  • this is achieved by a special design of the spray head, which ensures that the aqueous liquid emerging from the spray nozzle is mixed with air to such an extent that the liquid already hits the surface as foam.
  • Appropriately designed spray pumps are commercially available.
  • suitable design of the spray mechanism taking into account the composition of the cleaning liquid, must ensure that together with sufficient quantities of propellant gas always escape from the liquid, which then lead to foaming of the liquid. If necessary, shake before use.
  • the appropriate design of the aerosol container, intake manifold and valve is part of the routine work of a person skilled in the art and is therefore not to be explained in more detail here.
  • the amount of liquid sprayed onto the surface to be cleaned in the course of the cleaning process is usually between about 10 g and about 60 g / m 2; in particular 20 g to 40 g / m2.
  • the foam is expediently distributed as evenly as possible over the surface to be cleaned and can then develop its cleaning action automatically.
  • the surfaces are preferably subsequently wiped with a damp cloth or sponge, with larger surfaces being rinsed out with clear water from time to time.
  • the treated surfaces can of course also be rinsed with water, but this is generally not necessary as the remaining cleaning agent residues dry completely transparent and remain practically invisible.
