Definitions

  • Additive includes.
  • the invention relates to a mixture comprising two components I and II, an emulsion which are prepared from the mixture and may also be present as a microemulsion, in particular a bicontinuous microemulsion, and a cleaner, a cosmetic article and a foodstuff which comprise the emulsion and a use of the cleaner.
  • Surfactants are detergent substances (detergents) that are contained in detergents, dishwashing detergents, and shampoos. They have a characteristic structure and have at least one hydrophilic and one hydrophobic structural unit. They have an amphiphilic character. If the stabilizing character of water-oil mixtures is in the foreground, these amphiphilic substances are used as emulsifiers. Surfactants lower the interfacial tension between immiscible phases, a hydrophilic (water-soluble, lipophobic), mostly aqueous phase, and a hydrophobic (oil-soluble, lipophilic) phase. Such liquid two-phase mixtures are referred to as emulsions. Conventional emulsions may contain hydrophilic and hydrophobic phases in different volumes.
  • microemulsions are thermodynamically stable, emulsions disintegrate due to their instability. At the microscopic level, this difference is reflected in the fact that the emulsified liquids in microemulsions are enclosed in smaller volumes of liquid (eg 10 "15 ⁇ l_) as described in emulsions (eg 10 "12 ⁇ l_) as described in DE 10 2005 049 765 A. Thermodynamically unstable emulsions thus have larger structures.
  • Lamellar mesophases can occur in microemulsions. Lamellar mesophases lead to optical anisotropy and increased viscosity. These properties are for. B. undesirable for cleaners. In addition, phase separation often occurs when lamellar phases coexist with microemulsions.
  • Microemulsions consist of at least three components, namely oil, water and a surfactant [1-7]. Oil and water are immiscible and therefore form domains on the nanoscale. The surfactant mediates between these two components and allows a macroscopic-homogeneous mixture. On a microscopic scale, the surfactant forms a film between the oil and water domains. Microemulsions are macroscopically homogeneous, behave optically isotropically and are thermodynamically stable in contrast to emulsions. There are W / O and O / W droplet microemulsions in which water droplets from the oil or oil droplets are enclosed by the water. Approximately equal proportions of oil to water promote the formation of a bicontinuous microemulsion.
  • Characteristic of the efficiency of a surfactant is the minimum amount of surfactant required to stabilize emulsions over the desired period or to obtain a microemulsion.
  • Microemulsions have been extensively studied in the field of basic science [8, 9]. The knowledge gained is largely based on the use of pure, defined components: deionized water, chemically pure oils and pure surfactants. In technical microemulsions, the components usually consist of mixtures. As a result, the phase ratio changes considerably and the findings from basic research gained in simplified models can not be without further be transferred to technical applications. Another difficulty lies in the low temperature stability of microemulsions, since in practical formulations stability must be present over a wide temperature range. Particularly systems based on fatty alcohol ethoxylates frequently used are stable only in a very narrow temperature window of a few 0 C and extremely high levels of surfactant must be used.
  • microemulsions made with the aid of sugar surfactants can be stable over larger temperature ranges.
  • mixtures of nonionic and ionic surfactants can be used.
  • sugar surfactants and nonionic surfactant mixtures also have disadvantages.
  • Microemulsions of sugar surfactants can only be produced with the help of cosurfactants.
  • monohydric alcohols such as hexanol or octanol are used.
  • Microemulsions containing ionic surfactants are sensitive to changes in salt concentration.
  • Hazardous material potential They are particularly irritating to the skin and eyes.
  • alkyl polyglucosides which are produced from renewable raw materials and have only a moderate hazardous substance potential and are also relatively skin-friendly.
  • Sorbitan esters which have a very low hazard potential and are also largely produced from renewable raw materials, have been little explored in terms of their use in microemulsions so far.
  • DE-A-198 39 054 discloses a process for increasing the efficiency of surfactants with simultaneous suppression of lamellar mesophases, a process for stabilizing the temperature position of the single phase region for oil, water surfactant mixtures, a process for increasing the structure size of emulsified liquid particles in microemulsions and a A method for reducing the interfacial tension of oil-water mixtures to which AB block copolymers having a water-soluble block A and a water-insoluble block B are added.
  • the polymers consist of a water-soluble block A and a hydrophobic block.
  • the lower limits of the number average molecular weights for A and B are 500 g / mol. This method is suitable for the production of microemulsions.
  • DE-A-103 23 180 describes mixtures containing a surfactant and a cosurfactant which are characterized in that the cosurfactant used is an amphiphilic comb polymer comprising a backbone with two or more side chains attached to the backbone, the side chains being mutually interlinked and / or distinguish the side chains from the backbone in their amphiphilic character.
  • the cosurfactant is suitable for increasing the efficiency in microemulsions.
  • DE-A-4417476 discloses a microemulsion containing alkyl glycosides and fatty acid polyol partial esters.
  • the microemulsion should be present in a wide range of existence; however, a temperature range in which the microemulsion is stable is not disclosed.
  • DE-A-198 24 236 proposes a method for cleaning printing presses or printing plates, in which the contaminants are removed from the surfaces to be cleaned by washing with a microemulsion which Water, a surfactant and a water-immiscible organic solvent.
  • US-A-5719113 discloses detergents comprising an antibacterial substance, a nonionic surfactant and an amphoteric surfactant. In contrast to the mixture according to the invention, no second alcohol group-containing surfactant is disclosed.

  • This component II which is included as a polymeric additive in the mixture according to claim 1, seems to lead to an increase in the efficiency of the surfactants in component I.
  • surfactant saving is also advantageous for environmental or health reasons.
  • Surfactants are ecologically particularly relevant substances whose environmental compatibility must be ensured.
  • Another advantage of surfactant savings occurs when surfactants interfere with the application of the microemulsion.
  • cosmetics may be mentioned whose surfactant content should be as low as possible due to the skin-influencing effect possibly occurring in the case of sensitive skin or a potentially occurring eye-irritating effect of the surfactants. The same applies in particular to food. Consumer exposure to surfactants should be as low as possible. The present invention contributes to this.
