Definitions

  • the invention relates to a process for the preparation of light-colored alkyl and / or Alkenyloligoglycosid mixtures and their use in detergents, dishwashing detergents and cleaners.
  • Alkyl oligoglucosides are important surfactants because as nonionic compounds they are compatible with a variety of other ingredients but exhibit foam and detergency much more similar to anionic surfactants. Due to their good biodegradability and skin compatibility, they are used in cosmetics and in detergents, dishwashing detergents and cleaning agents. Their preparation is based on glucose and branched, unbranched, and saturated and unsaturated alcohols, which are acetalized in the presence of acidic catalysts. To shift the reaction equilibrium of the alcohol is usually used in considerable excess.
  • reaction mixtures with 20 to 50% of alkyl and / or Alkenyloligoglycoside and 50 to 80% alcohol, which has the consequence that the resulting glucosides must then be removed with high technical complexity of unreacted alcohol before they are then water be pasted and bleached.
