Definitions

  • the invention relates to aqueous cleaning agent concentrates for rough, in particular profiled, stoneware tiles and boards based on nonionic, anionic, or amphoteric surfactants which contain sorbitan esters as cleaning intensifiers.
  • stoneware stands for hard-fired tiles and slabs, which may be glazed or unglazed with or without a baked ceramic surface finish.
  • DIN standard a subdivision is made of water absorption capacity and type of production.
  • DIN EN 176 defines stoneware tiles and porcelain stoneware tiles.
  • the displacement space (V) according to DIN 51 130 is also specified for profiled slabs and tiles.
  • R 10 For areas with increased risk of slipping, areas in which floors and stairs are in contact with friction-reducing and / or sliding media such as water, waste residues, starchy residues, animal and vegetable fats or oils, mineral fats or oils, soaps, pigment soiling, rubber abrasion, silicones the evaluation groups> R 10, in particular R 12 and R 13 are appropriate.
  • Tiles and sheets are generally considered to be easy to clean and easy to clean. This applies unconditionally to flat, smooth and hard surfaces of R-Classes 9 to 11. With increasing R-Class, however, the surfaces become increasingly rougher. Problematic are fine-grained substrates of class R 12 and in particular profiled tiles and slabs of classes R 12 to 13 and V 8 to 10, so-called porcelain stoneware tiles / slabs.
  • the cleaning effort increases significantly with increasing roughness / unevenness of the substrate, especially if due to porosity additional surface enlargement is given.
  • cleaners for manual and machine cleaning are generally complex mixtures of anionic, nonionic and amphoteric / zwitterionic surfactants, which contain customary auxiliaries and additives such as alkalis, complexing agents, solubilizers, sodium hypochlorite and optionally mild abrasives. They are used in concentrations of about 0.5 to 10 wt .-% for use.
  • GB-A-2 334 723 describes cleaning compositions for glass, smooth, shiny and shiny surfaces consisting of one or more ethoxylated quaternary ammonium compounds, at least one glycol ether and / or C 1-22 alcohol and at least one anionic surfactant.
  • the cleaning agent should not stain or streak after cleaning, have anti-microbial and antistatic properties.
  • the special problem of cleaning rough, non-glossy profiled surfaces and the effect of spreading improvement by alkoxylated ammonium compounds is not mentioned here either.
  • ethoxylated quats which are no longer acceptable under ecological considerations, show good cleaning-enhancing properties, they no longer meet the requirements for surfactants in detergents. They do not reach the required biodegradation values according to OECD 301 A-F.
  • the cationic surfactants used in DE-A-100 38 198 or US Pat. No. 5,929,024 are ethoxylated alkylamidoalkyl-dialkylammonium salts which are known to be problematic and difficult to produce without serious side-effects and to have an increased aquatic toxicity as well Have worse total degradation than the commonly used nonionic or anionic surfactants.
  • Ethoxylated quats can be irritating to the skin and some of these compounds may even be toxic to aquatic organisms.
  • the material compatibility is not given on different surfaces. Here are mainly metallic surfaces to call on which cationic surfactants, even on stainless steel, lead to corrosion, especially to pitting. Essential for this are the counterions, mostly chloride ions.
  • the object of the present invention was therefore to overcome these disadvantages of the known commercially available cleaning agents and to provide improved cleaning agents which ensure reliable cleaning of rough and profiled tiles and panels, so-called porcelain stoneware, at the same or reduced application concentrations.
  • Another object of the invention is the use of the aqueous cleaning agent concentrates according to one or more of the claims for cleaning porcelain stoneware tiles.
  • aqueous detergent concentrates according to the present invention contain, based on the total mixture, water in the range of about 45 to about 95 parts by weight, preferably about 70 to about 90 parts by weight. In case of application, they can be diluted with additional water to the particular desired or usual or required application concentration of about 0.3 parts by weight to about 10 parts by weight.
  • Suitable sorbitan esters are the mono-, di- and. Triesters of sorbitans with fatty acids as well as sorbitan sesquiester or polysorbates. As Sorbitansesquiester called the mixture of mono- u. Diesters of fatty acids with sorbitan. The ethoxylated sorbitan esters are referred to as polysorbates. (J. Am., Oil Chem Soc 66, 1581 (1989) Surfactants Surf., Deterg., 27, 350 (1990).
  • Fatty acids which can be used according to the invention are those with R based on saturated or unsaturated monobasic or unsaturated natural or synthetic aliphatic fatty acids having 6 to 22 carbon atoms, preferably 6 to 18, in particular 6 to 10 carbon atoms which may optionally be branched, optionally substituted and or contain heteroatoms.
  • Suitable fatty acids are, in particular, fatty acids which have a chain distribution of about 6 to about 18, in particular about 6 to about 10 carbon atoms and are both branched, substituted, preferably -OH-substituted, saturated and also may be unsaturated, such as on known and conventional monobasic fatty acids based on natural vegetable or animal oils having 6 to 22 carbon atoms such as undecanoic, lauric, myristic, palmitic, palmitoleic, isostearic, stearic, oleic, linoleic, petroselic, elaidic, arachidic, behenic , Eurucic acid, gadoleic acid, rapeseed oil fatty acid, soybean oil fatty acid, sunflower oil fatty acid, tall oil fatty acid which can be used alone or mixed in the form of their glycerides, methyl or ethyl esters or as free acids, and the technical mixtures obtained in the pressure cracking.
  • fatty acids with a similar chain distribution are suitable.
  • Particularly preferred according to the invention are caproic acid, hydroxycaproic acid or caprolactone, sorbic acid, enanthic acid, caprylic acid, 2-ethylhexanoic acid, pelargonic acid, capric acid.
  • Suitable alkoxylating agents are ethylene oxide, propylene oxide or butylene oxide, alone or as copolymers with both random and blockwise distribution.
  • the degree of alkoxylation is determined by the desired hydrophilicity of the compound. It is on average between 1 to 25, especially 4 to 20.
  • These compounds are prepared by the known processes by chemical condensation processes in the desired molar ratio or by enzyme-catalyzed esterification or transesterification. While it is possible to prepare substantially pure mono- or diesters with the enzyme-catalyzed processes, the chemically catalyzed reaction products are present as technical mixtures which, in addition to the desired mono-, di- or triester, always also contain fractions of the other esters. These technical esters can be purified by the known methods, ie concentrated to the respective mono / di / tri portions, but are also readily usable.
  • cleaning formulations consisting of mixtures of one or more surfactants from the group of anionic, nonionic, amphoteric compounds and optionally conventional auxiliaries and additives such as alkalis, complexing agents, solubilizers, chlorine bleach and mild abrasives in amounts of about 0.1 to 5, especially 0 , 5 to 3 parts by weight added.
  • the surface-active compounds which can be used according to the invention are the anionic, nonionic, amphoteric / zwitterionic surfactants customary in this field for the preparation of household and industrial cleaners.
  • the compounds can be used individually or as mixtures and are, for example, anionic, nonionic and amphoteric surfactants such as alkali metal, ammonium or magnesium alkyl sulfates or alkyl ether sulfates, secondary alkanesulfonates, alkali ⁇ -olefin sulfonates, sulfosuccinates, acyl isethionates, sarcosides, taurides, ether citrates , Carboxylates, ether carboxylates, alkyl amide ether sulfates and amine oxides, alkyl betaines, alkyl amidobetaines, propionates, glycinates, acetates and sulfobetaines and sodium, potassium or triethanolamine soaps.
  • anionic, nonionic and amphoteric surfactants such as alkali metal, ammonium or magnesium alkyl sulfates or alkyl ether sul
  • secondary alkanesulfonates or alkyl sulfates or linear alkylbenzenesulfonates are used in the detergent formulation according to the invention; C 8-14- alkyl sulfates and C 8 -alkanesulfonates are particularly preferred.
  • Preferred nonionic surfactants are the fatty alcohol polyglycol ethers.
  • EO ethylene
  • PO propylene oxide
  • amphoteric surfactants are commonly used in such systems.
  • amphoglycinates in particular capryliminodipropionate and caprylamphopropionate, are preferred here, since both surfactants show good cleaning performance and good resistance at high pH values and introduce a low foam load into the system.
  • the builder system consists of alkali hydroxide, in which case the potassium hydroxide is preferred and a complexing agent which can be selected from the following group:
  • NTA nitrilotriacetic acid and its sodium salts
  • EDTA DTPA
  • diethylenetriaminepentaacetic acid PDTA
  • propylenediaminetetraacetic acid ADA
  • alaninediacetic acid Na salt
  • MGDA methylglycinediacetic acid

  • the cleaners prepared as shown in the table above were used at a 1.2% dilution and the contact angle on Villeroy & Boch tiles of the "ATHOS" brand was determined using the contact angle measuring device "Krüss DSA 10 HS".
  • the cleaners according to the invention were heated to 1.2% dilution to 20.0 ° C. and measured in a room conditioned at 20 ° C.
  • the contaminated tiles were first coarse with water and then with ethyl acetate p. A. of the evt1. leftover residues of the use dilution cleaned.
  • the tiles were stored in a box at 20 ° C in an air-conditioned room to protect them from environmental influences and dust and to ensure the measuring temperature of 20 ° C.
  • Test solution E contains only short-chain anionic surfactants, in such surfactant systems, a weakness in the emulsification behavior is known.
  • the emulsification behavior of low-emulsifying, short-chain anionic surfactant solutions is greatly optimized by adding the cleaning intensifiers according to the invention.
  • the emulsion breaks water now settles in place of the oil. This settling water does not affect the cleaning power or the dirt carrying capacity during cleaning.
  • the sorbitan esters show a significant gain in emulsifying power, i. translates for cleaning applications increased dirt carrying capacity.
  • the sunflower oil was aged under heat and then with an organic solvent in the Ratio 1: 1 added. This mixture was stirred for 24 hours and then the remaining components of the soiling were added. This soil suspension was then sprayed on pre-cleaned porcelain stoneware tiles and dried defined.
  • test products the following dilutions were made with city water (12 ° dH).
  • the soiled test surfaces were cleaned after drying with a wiper tester.
  • the wiper tester offers the possibility of testing up to four cleaners in parallel on a test surface. Care was taken to ensure that the position of the cleaners to be examined on the surface to be cleaned was randomized.
