Definitions

  • Liquid cleaning agents usually consist of aqueous solutions of synthetic anionic and / or nonionic surfactants and conventional additives. They are particularly used for cleaning hard surfaces, for example glass, ceramic materials, plastics, painted and polished surfaces.
  • An important area of application for liquid detergents is the manual washing of dinnerware and cookware.
  • the dishes are usually cleaned in slightly diluted liquors at slightly elevated temperatures of around 35 to 45 ° C.
  • the cleaning power of an agent is generally assessed by the consumer the better and the longer the cleaning liquor foams. Because of the contact of the hands with the cleaning liquor over a longer period of time, the skin-friendliness of the agent is of particular importance when washing dishes.
  • agents are preferred which are free from the proportions of anionic surfactants based on petrochemicals, such as e.g. B. alkylbenzenesulfonates and alkanesulfonates.
  • alkyl sulfates and alkyl ether sulfates are not only degraded very well not only in the aerobic activation stage of the sewage treatment plants, but also under anaerobic conditions of sludge digestion (e.g. J. Steber, P. Code, W. Guhl: Fat. Sci. Technol. 90 (1) , 32 (1988)).
  • alkyl ether sulfates that is to say salts of sulfated adducts of about 2 to 5 moles of ethylene oxide with fatty alcohols having about 10 to 18, preferably 12 to 16, carbon atoms in the aliphatic radical have good foaming and cleaning power and skin-friendly properties.
  • the commercially available, manual dishwashing detergents are therefore generally aqueous solutions of such alkyl ether sulfates in conjunction with other surfactants, in particular alkylbenzenesulfonates and alkanesulfonates, and also solubilizers, colors and fragrances.
  • Swiss patent specification 354 195 discloses liquid detergents for manual dishwashing, which are a combination of an alkyl ether sulfate containing alkyl sulfate and a nonionic surfactant of the fatty acid alkanolamide type from mono- or dialkanolamides with no more than 3 carbon atoms in each alkanol residue of saturated fatty acids with 10 Contain up to 14 carbon atoms, together with water, solubilizers, colors and fragrances and, among other things, have a low solidification point.
  • nonionic alkyl monoglucosides not only develop stable foam themselves, but also act as foam stabilizers for other anionic and nonionic surfactants.
  • European patent application 70 074 discloses foaming liquid cleaning agents containing anionic surfactants, in particular alkylbenzenesulfonates, alkylglucosides and amine oxides or fatty acid alkanolamides, the alkylglucosides being alkyloligoglucosides which contain the glucose unit (GE) about 1.5 to 10 times, acts.
  • This value is an average value and also takes into account the presence of alkyl monoglucosides in a corresponding proportion.
  • Alkyl glucosides with a degree of oligomerization higher than 2 are found to be particularly suitable. Mixtures of such alkyl glucosides and alkyl ether sulfates in a ratio of 3: 2 are described as only slightly foaming.
  • liquid detergents for the manual cleaning of dishes containing synthetic anionic surfactants of the sulfonate and / or sulfate surfactant type, fatty alkyl glucosides and optionally fatty acid alkanolamides are described Fatty alkyl glucosides with an average of less than 2 GE per fatty alkyl radical, in particular 1 to 1.4 GE, contain.
  • European patent application 341 071 describes liquid detergents for manual dishwashing described with an active substance content of 5 to 60 wt .-%, 30 to 60 wt .-% of an alkyl glucoside with preferably 1 to 1.4 GE in the molecule, 12 to 30 wt .-% of a betaine and up to 1.5 times the amount, based on the betaine, can consist of alkyl sulfates and / or alkyl ether sulfates. These surfactant mixtures are said to be characterized by good foam stability and good cleaning performance.
  • the invention thus relates to aqueous liquid cleaning agents, in particular for manual dishwashing, with an active substance content of 10 to 60, preferably 15 to 40 percent by weight, consisting of alkyl sulfates, alkyl ether sulfates, betaines and fatty alkyl glucosides with less than 2, in particular 1 to 1, 4, glucose Units per fatty alkyl radical, which are characterized in that they contain more than 45% of the active substance of alkyl sulfates and alkyl ether sulfates, their content being greater than 1.5 times the betaine content and at least twice the alkyl glucoside content and a maximum of about 50 times the betaine and / or fatty alkyl glucoside content and the fatty alkyl radical of the fatty alkyl glucoside has 12 to 14 carbon atoms.
  • alkyl sulfates or alkyl ether sulfates used with preference are commercially available, they have a straight-chain, aliphatic C 12-18 , preferably C 12-14, alkyl radical.
  • the associated cation is preferably an alkali metal or ammonium ion.
  • the degree of ethoxylation is 1 to 5, preferably 2 to 4.
  • alkyl ether sulfate mixture consisting of 50% by weight of a C 12 alkyl ether sulfate and 50% by weight of a C 14 alkyl ether sulfate with 1 to 5, preferably 2 to 4, ethylene oxide groups instead of or together with the alkyl ether sulfate mixture (es) which is usually used and which contains the same components in a weight ratio of 70:30.
  • alkyl ether sulfate mixture es
  • Small amounts of shorter or longer alkyl chains in alkyl sulfates and / or alkyl ether sulfates change the results only insignificantly.
  • the known proportion of alkyl sulfate in industrially produced alkyl ether sulfates is included here.
  • the claimed alkyl sulfate content is added separately.
  • the quantitative ratio of alkyl sulfate to alkyl ether sulfate is preferably 4: 1 to 1: 5.
  • the alkyl glucosides are of the fatty alcohol glucoside type. Compounds with an average of less than 2 GE per fatty alkyl radical are understood here, in particular those with 1.0 to 1.4 GE.
  • the fatty alkyl group has 12 to 14 carbon atoms. “Fatty alkyl” is understood to mean the residues of the fatty alcohols produced by hydrogenation of natural fatty acids that are wholly or predominantly saturated.
  • agents according to the invention can preferably also contain solubilizers, solvents, colorants and fragrances.
  • Alkanolamines polyols, such as ethylene glycol, 1,2-propylene glycol or glycerol, for example, can serve as solubilizers, for example for small amounts of dye and perfume oil.
  • the amounts used are generally between 1 and 15 percent by weight, based on the total agent.
  • solvents such as low molecular weight alkanols with 1 to 4 carbon atoms in the molecule, preferably ethanol and isopropyl alcohol, are used.
  • the amounts used are up to 15 percent by weight, based on the total agent.
  • Viscosity regulators such as urea, sodium chloride, ammonium chloride, magnesium chloride and salts of mono-, di- and tricarboxylic acids and mixtures thereof can also be used individually or in combination in the required amounts.
  • Other common optional additives are corrosion inhibitors and preservatives.
  • a remainder, to be calculated for a total of 100 percent by weight, for the total composition consists of water.
  • liquid detergents according to the invention according to the following examples were obtained by stirring the individual constituents together and leaving the mixture to stand until there were no bubbles.
  • the neutral combinations listed were adjusted with sodium chloride and / or ethanol to viscosities between 300 and 400 mPas (according to Höppler, 20 ° C).
  • the samples were stored at -15 ° C for 24 hours.
  • the temperature at which the products became optically clear was determined as a clear point.
  • the saucers are each covered with 2 g of melted beef tallow (test soil A). Then 8 liters of tap water (16 ° d) at 50 ° C are placed in a bowl. To clean the plates soiled with (A), 4 g, i.e. 0.5 g / l of the detergent was added and the plates washed. The plates listed in Table 3 could be rinsed clean until the foam of the initially foaming solution disappeared.
  • the saucers are each covered with 2 g mixed soiling (test soiling B).
  • This soiling is obtained by mixing water, fat and carbohydrates (Mi No 1 from Henkel) with water. Then 8 liters of tap water (16 ° d) at 45 ° C are placed in a bowl. To clean the plates soiled with (B), 3.2 g, ie 0.4 g / l, of the cleaning agent prepared were added and the plates were washed. The plates that were rinsed clean until the foam disappeared are listed in Table 3.
