Definitions

  • Enzyme-stabilizing surfactant mixture and liquid detergents and cleaning agents containing them The invention relates to a surfactant mixture which, in particular in liquid detergents or cleaning agents, has an enzyme-stabilizing effect.

  • enzymes or enzyme combinations to improve the cleaning effect of detergents and cleaning agents is generally known in the field of detergents and cleaning agents.
  • the enzymes most commonly used include proteases, amylases, cellulases, lipases and mannanases. These enzymes can each have different properties from one another and come from different sources.
  • Enzyme-containing detergents and cleaning agents often have the disadvantage that the enzymes contained therein have only a limited stability and the washing and cleaning properties deteriorate significantly even after short storage times. This also applies to agents to which enzyme stabilizers have been added. This problem occurs in particular with liquid formulations and there in particular with formulations with a higher water content. Surfactants can also have a negative influence on the enzyme stability, so that there is a need for enzyme-compatible, yet powerful surfactant systems.
