Definitions

  • the present invention relates to a surfactant mixture consisting of at least one anionic and at least one amphoteric surfactant, a surfactant mixture consisting of isotridecanol which is alkoxylated with ethylene oxide and myristyl and / or lauryldimethylamine oxide, the use of appropriate surfactant mixtures for lowering the micelle concentration, increasing the wetting rate and Improvement of the adsorption at interfaces and cleaning agents containing the surfactant mixtures according to the invention.
  • Alcohols such as ethanol and isopropanol are often used to set the surface tension of the solvent water to low values and thus meet the requirements for rapid wetting.
  • the alcohols are a problem for people and the environment because of their volatility.
  • the very good wetting effect of hydrophobic alcohols which can be produced from acetylenes and aldehydes, is known.
  • These molecules do not form micelles and are therefore unable to detach, emulsify or solubilize hydrophobic substances from surfaces.
  • US 4,276,205 discloses a surfactant composition with improved cleaning power in cold water, comprising an amine oxide, an ethoxylated alcohol or an ethoxylated alkylphenol and a condensation product of C 2 -C 4 alkylene oxides with a molecular weight of 2,000 to 40,000 g / mol.
  • US 4,405,483 discloses a liquid cleaning composition comprising a surfactant, an aluminosilicate ion exchange material, a stabilizing agent and a polymeric compound which absorbs calcium and magnesium ions in water.
  • WO 99/19438 discloses an aqueous cleaning composition which is free from anionic surfactants and which contains linear ethoxylated alcohols and an amine oxide or a betaine.
  • the composition contains, for example, cationic ammonium compounds as an optional component.
  • Surfactant mixtures containing combinations of specified ethoxylated zwitterionic compounds with other cleaning agents, disclosed in US 3,929,678, are suitable for the removal of contaminants.
  • EP 0 347 199 A2 discloses aqueous shampoo compositions which contain sodium or ammonium dialkyl sulfosuccinates and antimicrobial compounds such as 1-hydroxy-2-pyrridone and 1-imidazoyl-2-butanone or derivatives thereof.
  • DE 199 18 267 A1 discloses a hand dishwashing detergent in which the sensitive ingredients are incorporated in an easily manageable form that is stable in temperature, storage and transportation. This is achieved by a thickened surfactant containing anionic and amphoteric surfactants, polymers and microcapsules.
  • Processes such as the application of crop protection agents, the coating of car bodies with aqueous pigment dispersions, metalworking, paper and textile manufacture, printing and dyeing are based on fast-running spraying and wetting processes.
  • highly dynamic surfactants are required, which can reduce the surface and interfacial tension within milliseconds.
  • These surfactants are usually amphiphiles with a short alkyl chain or branched structures; usually structures with a high micelle concentration and thus a high concentration of non-micellar bound molecules. This is associated with rapid diffusion to the interface, formation of an interface film and lowering of the interface energy as a prerequisite for effective wetting and the formation of small droplets when spraying. Since these structures generally have a high micelle formation concentration, the prerequisite for simultaneous emulsification and solubilization, for example in order to remove oily dirt in washing and cleaning processes, does not exist at low application concentrations.
  • Surfactants have the property of attaching to interfaces and reducing the interfacial energy between two phases. They consist of a hydrophilic and a hydrophobic part of the molecule, the surfactant molecules in aqueous solution attaching to the interfaces with increasing surfactant concentration until these are completely occupied. Above a certain concentration, the free surfactants remaining in the solution form agglomerates, which are called micelles. This Limit concentration is called critical micelle formation concentration (cmc), ie above this concentration the surfactants form micelles.
  • cmc critical micelle formation concentration
  • a problem with the surfactants and mixtures of surfactants known from the prior art is that they are either highly dynamic and thus rapidly absorb at interfaces, form an interface film and thereby reduce the interfacial energy, or that they have a low micelle formation concentration, so that the prerequisites for emulsifying, solubilizing or loosening dirt. Since these two requirements are not present at the same time, the known surfactants or surfactant mixtures can only be used in a limited range of applications.
  • the object of the present invention is to provide surfactant mixtures which are highly dynamic and thus adsorb rapidly at interfaces, form an interface film and thereby reduce the interface energy.
  • These surfactant mixtures should at the same time have a low micelle formation concentration, so that there is also the prerequisite for emulsification, solubilization or for removing dirt, and the surfactant systems can therefore be used over a broader range of applications.
