Definitions

  • the present invention relates to the cleaning of surfaces, particularly of textiles, as well as to the provision of liquid compositions for this purpose.
  • detergents compositions usually contain a wide variety of active ingredients.
  • a person skilled in the art is familiar with contaminants, for example, that can be better removed through the use of enzymes - so-called enzyme- sensitive contaminants. Therefore, in addition to the surfactants that are commonly used for soil removal of enzyme-sensitive contaminants, enzymes, for example selected from protease, lipase, amylase, and/or mannanase, are additionally added to detergents compositions.
  • the activity of the enzymes during the washing or cleaning process depends on various factors. Besides the temperature and the pH value of the detergent or cleaning agent, the storage stability of the enzyme in the detergent composition is a crucial factor. A high degree of enzyme activity should also be ensured for the entire period of time from the production of the detergent composition through the last use by the consumer.

  • these effects are to be achieved at application temperatures that are as low as possible, particularly between 10 °C and 40 °C.
  • the washing performance provided by the enzyme should be sustained to the greatest possible extent over the storage period of the detergent or cleaning agent.
  • the foam level of a liquid detergent formulation during the use in an automatic washing machine is typically controlled by the addition of soap.
  • High soap levels of 3 wt.% or more are frequently used to reduce the foaming power of the wash liquor.

  • Higher soap levels lead to formula instabilities upon storage especially at lower temperatures (e.g. 0°C).
  • a reduction of the foam level by reducing the overall surfactant level of the formula leads to a general reduction of the stain removal performance, which is not desired. It was therefore another objective of the invention to combine an outstanding washing performance with a low foam level of the wash liquor and a good stability of the overall liquid detergent composition upon storage at low temperatures.
