Definitions

  • the invention is in the detergent sector and relates to mixtures of alkyl glucosides of different chain lengths and their use for the production of detergents.
  • Alkyl oligoglucosides are nonionic surfactants that are produced by acidic acetalization of glucose or starch degradation products with primary alcohols. By choosing the process conditions, the average degree of polymerization, i.e. control the distribution of acetalized mono-, di-, tri- and oligoglucosides. If you also vary the chain length of the alcohol component or even use mixtures of different alcohols, countless types of alkyl oligoglucosides are available, which differ in their primary detergent properties - washing, emulsifying, foaming, wetting - more or less clearly.
  • Alkyl oligoglucosides are characterized by their foaming power, which clearly exceeds that of conventional nonionic surfactants and is more similar to anionic surfactants. This is undoubtedly an advantage for use in the area of manual dishwashing detergents or hair shampoos, whereas in the area of detergents, the opposite behavior, namely low foam, is desired in order to prevent the washing machine from overflowing or to keep the amount of defoamer required as low as possible .
  • Another problem is that the commercially available alkyl oligoglucosides, especially with regard to cosmetic soiling, show a rather average cleaning ability. This explains why alkyl oligoglucosides have so far only been used in modest amounts in detergent formulations. In this connection, reference is made to the two German patent applications DE-A1 4319699 and DE-A1 4319700, from which mild alkyl oligoglucoside mixtures with defined chain lengths and DP are known.
  • the complex object of the invention was therefore to provide new alkyl oligoglucosides which, with reduced foaming, should be distinguished by improved washability, in particular in relation to cosmetic soiling.
  • the invention relates to a nonionic surfactant mixture consisting of (a) alkyl oligoglucosides of the formula (I),
  • R 1 is a dodecyl / tetradecyl radical
  • G is a glucose radical
  • p1 is a number in the range from 1 to 3
  • R 2 is a hexadecyl radical

  • the mixtures compared to conventional commercial products with reduced foaming, are distinguished by improved washing performance, in particular by cosmetic soiling.
  • Alkyl oligoglucosides are known nonionic surfactants which are usually prepared by acid-catalyzed acetalization of glucose or degraded starch syrup with primary alcohols; the catalyst is then neutralized and excess alcohol is distilled off.
  • Representative of the extensive literature here is the review by Biermann et al. in Starch /force 45, 281 (1993), B.Salka in Cosm.Toil. 108, 89 (1993) and J.Kahre et al. in S ⁇ FW- Journal issue 8, 598 (1995).
  • the DP ie the average degree of polymerization
  • the index number p1 or p2 for the individual, to a certain extent, chain-pure alkyl glucosides can be in the range from 1 to 3, since in the sense of the invention it is only important that the mixture has a DP of 1.4 to 1.5 having. This can be important, for example, if the surfactant mixtures are produced by mixing the individual glucosides.
  • the surfactant mixtures preferably contain those alkyl oligoglucosides of the formula (I) which have the dodecyl and tetradecyl glucosides in a weight ratio of 25:75 to 75:25, preferably 40:60 to 60:40.
