Definitions

  • the invention relates to a combination of fatty acid and or its salts and (meth) acrylic acid (co) polymer in detergents or cleaners containing surfactant (s) and other conventional ingredients of detergents or cleaners.
  • Liquid detergents or cleaners are often offered in thickened form and contain a thickener or a thickener system.
  • the thickening effect of known thickeners or thickener systems depends, on the one hand, on the other ingredients of the washing or cleaning agent to be thickened, such as, for example, the surfactants, electrolytes, solvents or perfume oils. Furthermore, the pH of the detergent or cleaning agent to be thickened can have a great influence on the thickening effect.
  • Frequently used thickeners are polyacrylate thickeners. These show in liquid detergents or cleaners at a pH in the range of 8 to 9, the best thickening effect. In this pH range, however, there are very large fluctuations in the viscosity of the liquid detergents or cleaners, which can be up to 1000 mPas. Such large fluctuations are extremely undesirable in terms of production technology.
  • the viscosity of detergents or cleaning agents containing fatty acid soap can be increased within certain limits by lowering the pH. However, larger amounts of unsaponified fatty acid can lead to cloudiness and instability.
