Definitions

  • the invention relates to detergents and cleaning agents based on alkyl glycosides and synthetic anionic surfactants.
  • alkyl glycosides which are acetals from sugars and fatty alcohols with at least 8 carbon atoms, can be produced entirely from renewable raw materials, namely fat on the one hand and sugars or starches on the other hand.
  • alkyl oligoglycoside, alkyl polyglycoside, alkyl oligosaccharide and alkyl polysaccharide refer to those alkylated glycoses in which 1 acetal-like alkyl radical is accounted for by more than one glycose radical, that is to say one poly or oligosaccharide radical. These terms are considered to be synonymous with each other.
  • alkyl monoglycoside means the acetal of a monosaccharide. Since the reaction products from the sugars and the alcohols are usually mixtures, the term alkyl glycoside means both alkyl monoglycosides and alkyl poly (oligo) glycosides, unless the structural differences are important.
  • Such ternary alkyl glycoside mixtures have already been used in combination with other known anionic or nonionic surfactants.
  • European patent application 75 995 describes mixtures of alkyl polysaccharides and other nonionic surfactants.
  • European patent application 105 556 discloses cleaning agents which contain alkyl polysaccharides, another nonionic surfactant and an anionic surfactant from the group consisting of glyceryl ether sulfonates, ethoxylated alkylphenol ether sulfates, alkyl sulfates and alkylbenzenesulfonates.
  • alkyl glycoside mixtures are combined with anionic surfactants and, if appropriate, other conventional detergent and cleaning agent components.
  • Preferred anionic surfactants are saturated or unsaturated soaps, which can be hydroxylated or sulfonated in the ⁇ -position, and in particular alkylbenzenesulfonates.
  • the alkyl poly (oligo) glycosides used contain about 1.5 to 10 glycose units per molecule. This value is an average value and also takes into account the presence of alkyl monoglycosides in a corresponding proportion. However, alkyl glucosides with a degree of oligomerization of 2 or higher are found to be particularly suitable.
  • the economically most important anion surfactant which is also used most frequently in combination with ternary alkyl glycoside mixtures, belongs to the surfactant class of alkyl benzene sulfonates.
  • the production of the alkylbenzenesulfonates from petrochemical raw materials must be regarded as a disadvantage.
  • the present invention has for its object to provide a detergent and cleaning agent which contains a combination of nonionic surfactants and an anionic surfactant from the group of sulfates and sulfonates, which are completely obtainable from native, that is, renewable oleochemical raw materials.
