Definitions

  • the invention relates to new aqueous bleaching and disinfecting agents containing alkali metal hypochlorites, alkylene glycol ethers and selected surfactants in defined proportions.
  • EP-A 0274885 (ICI) recommends the use of mixtures of linear and branched amine oxides. According to the teaching of EP-A 0145084 (Unilever), mixtures of amine oxides with soaps, sarcosinates, thaws or sugar esters can also be used for this purpose.
  • EP-A 0079102, EP-A 0137551 and EP-A 0447261 disclose the use of amine oxides with soap or sarcosinate and other anionic surfactants, for example alkyl sulfates, alkyl ether sulfates, secondary alkane sulfonates or alkylbenzenesulfonates as a thickening component.
  • EP-A 0156438 reports on the use of alkylarylsulfonates as thickeners in aqueous bleaching agents which contain certain stilbene dyes as optical brighteners.
  • ES-A 8801389 (Henkel Iberica) relates to bleaching agents based on aqueous hypochlorite solutions which contain, as the surfactant component, predominantly alkyl ether sulfates and also small amounts of amine oxides. From EP-A1 0447261 aqueous bleaching agent compositions are also tongues containing sodium hypochlorite and anionic surfactants known. However, the hypochlorite concentration of these agents is 0.1 to 8 and preferably 0.5 to 5% by weight of active chlorine.
  • German Patent DE-C1 4333100 the applicant has already proposed stable and sufficiently viscous aqueous bleaching and cleaning agents based on hypochlorites, fatty alcohol ether sulfates and amine oxides, which contain amine oxide phosphonic acids as a mandatory component. Although these contribute significantly to the thickening of the agents, they cannot stabilize the active chlorine content.
  • US Pat. No. 4,588,514 discloses alkaline hypochlorite bleaches which contain amine oxides and small amounts of alkyl ether sulfates and soaps to adjust the viscosity. However, the preparations have a high hypochlorite content of 7% by weight. If the teaching is applied to modern bleaching agents with a low active chlorine content, neither sufficiently thickened nor storage-stable products are obtained.
  • the object of the invention was therefore to provide new aqueous bleaching and disinfecting agents which are characterized by a sufficiently high and stable viscosity at a low active chlorine content and which have excellent cleaning properties on hard surfaces, in particular with regard to greasy soiling.
  • the invention relates to bleaching and disinfecting agents containing - based on the agents -
  • R 1 and R 3 independently of one another represent linear or branched alkyl radicals having 1 to 8 carbon atoms
  • R 2 represents hydrogen or methyl
  • n represents numbers from 1 to 4
  • bleaching agents and disinfectants of the stated composition are not only chlorine-stable and sufficiently viscous, but also have improved cleaning properties, in particular with respect to greasy soiling.
  • Alkali metal hypochlorites are to be understood as meaning lithium, potassium and in particular sodium hypochlorite.
  • the hypochlorites can preferably be used in amounts of 2 to 4% by weight, based on the composition.
  • the alkylene glycol ethers to be used as component (b) in the context of the invention are known sales products. These are Ci-C ⁇ - and preferably C ⁇ -C -alkyl end group-blocked alkylene glycols, such as, for example, the dimethyl, diethyl, diisiopropyl, n -Butyl, tert-butyl, n-octyl and 2-ethylhexyl ether of ethylene glycol, diethylene glycol, triethylene glycols, propylene glycols, dipropylene glycols and tripropylene glycols. Dipropylene glycol dimethyl ether, which is commercially available under the Proglyde® DMM brand, is preferably used.
  • the alkylene glycol ethers can preferably be used in amounts of 1 to 3% by weight.
  • Alkyl ether sulfates are known anionic surfactants which are obtained by sulfation of nonionic surfactants of the alkylpolyglycol ether type and subsequent neutralization.
  • the alkyl ether sulfates which are suitable for the purposes of the agents according to the invention follow the formula (II),
  • R 4 represents an alkyl radical having 12 to 18 carbon atoms
  • n represents numbers 2 to 5
  • X represents sodium or potassium.
  • Typical examples are the sodium salts of sulfates of the Ci2 i4 coco alcohol 2, 2, 3, and 3 EO adduct.
  • the alkyl ether sulfates can have a conventional or narrow homolog distribution.
  • the alkyl ether sulfates are preferably used in amounts of 2 to 4% by weight, based on the composition.
  • Amine oxides are also known substances, which are occasionally attributed to the cationic, but usually the nonionic surfactants. They are prepared from tertiary fatty amines, which usually have either one long and two short or two long and one short alkyl radical, and are oxidized in the presence of hydrogen peroxide.
  • the amine oxides which are suitable for the purposes of the invention follow the formula (III)
  • R 5 represents a linear or branched alkyl radical having 12 to 18 carbon atoms
  • R 6 and R 7 independently of one another represent R 5 or an optionally hydroxy-substituted alkyl radical having 1 to 4 carbon atoms.
  • Amine oxides of the formula (III) are preferably used in which R 5 and R 6 are C-12/14 and C-12/18 cocoalkyl radicals and R 7 is a methyl or a hydroxyethyl radical.
  • amine oxides of the formula (III) in which R 5 is a C-12/14 or C1218 cocoalkyl radical and R 6 and R 7 have the meaning of a methyl or hydroxyethyl radical.
  • the amine oxides are preferably used in amounts of 1.5 to 3% by weight, based on the composition.
  • the agents according to the invention may contain fatty acid salts of the formula (IV) as further constituents,
  • R 8 CO represents an acyl radical having 12 to 22 carbon atoms and X represents an alkali metal.
  • Typical examples are the sodium and / or potassium salts of lauric acid, myristic acid, palmitic acid, palmoleic acid, stearic acid, isostearic acid, oleic acid, elaidic acid, petroselinic acid, linoleic acid, linolenic acid, elaeostearic acid, arachic acid, gadoleic acid, behenic acid and erucic acid and their mixtures they occur during the pressure splitting of technical fats and oils. Salts of technical coconut or tallow fatty acids are preferably used.
  • the fatty acids which are neutralized in situ when they are introduced into the mixture can also be used instead of the salts.
  • the fatty acid salts are preferably used in amounts of 1.5 to 2% by weight.
  • Suitable alkali metal hydroxides are potassium hydroxide and in particular sodium hydroxide, which are preferably used in amounts of 1.5 to 2% by weight and are used to adjust the pH of the compositions to an optimal value of 12.5 to 14.
  • the agents according to the invention with a content of cleaning-enhancing alkylene glycol ethers have a viscosity above 1000 mPas - measured at 20 ° C. in a Brookfield viscometer -, are stable in storage, resistant to chlorine consumption and, in addition to high cleaning properties, are also distinguished in particular by greasy soiling due to its excellent dispersibility for dye pigments.
  • Another object of the invention therefore relates to the use of alkylene glycol ethers of the formula (I) as cleaning enhancers for the production of hypochlorite-containing bleaching agents and disinfectants.
  • Auxiliaries and additives which the preparations may further contain include, for example, other chlorine-stable surfactants or hydrotropes, such as alkyl sulfates, alkyl sulfonates, alkyl benzenesulfonates, xylene sulfonates, sarcosinates, taurides, isethionates, sulfosuccinates, betaines, sugar esters, fatty alcohol polyglycol ethers and Alkyl oligoglycosides.
