Definitions

  • the invention relates to a detergent for washing laundry (textiles) with two separate phases (components) and a method for dosing a detergent by means of an automatic dosing device for separate dosing of various components of a detergent.
  • Liquid detergents do not achieve the cleaning performance of powder detergents when washing laundry. In essence, this is due to lack of bleaching power and a poorer builder system. If builders acting effectively in liquid detergents were integrated, the formulation would become unstable. If liquid bleaches were incorporated into liquid detergents, then enzymes would be damaged and the cleaning performance would decrease.
  • the maximum achievable cleaning performance with automatic liquid metering in the household sector is dictated by the liquid detergent.
  • effective complexing agents can not be integrated into liquid detergents, the cleaning performance compared to powdered detergents, which have a strong builder system, drops significantly.
  • the invention was thus based on the object of proposing a detergent with as few separate components as possible in order, on the one hand, to obtain an effectively acting, stably storable liquid detergent for washing laundry and, on the other hand, to minimize the amount of construction work required for dosing in a washing machine.
  • the detergent according to claim 1 contains only two components, on the one hand, the constructive and structural complexity (for example in washing machines) for metering these components is limited. On the other hand, already at the Using only two components a significantly better cleaning performance can be achieved compared to the use of a liquid detergent containing the ingredients in only one component.
  • component is used in the context of the present invention to describe the different, separate phases of the detergent, wherein each “component” contains at least one, preferably several ingredients, which serve the cleaning performance of the detergent.
  • the “components” of the detergent together provide the efficiently effective composition of the detergent.
  • the term “booster” describes the second component of the detergent which is added to enhance the cleaning performance of the detergent in the washing process.

  • incompatible components such as, for example, bleaches and enzymes, can also interact with one another during washing without first having to be mixed with one another during storage and transport.
  • liquid detergent as the first component and the booster as the second component

  • Amphoteric or ampholytic surfactants have several functional groups that can ionize in aqueous solution and thereby - depending on the conditions of the medium - give the compounds anionic or cationic character. Near the isoelectric point, the amphoteric surfactants form internal salts, rendering them difficult or insoluble in water. Amphoteric surfactants are subdivided into ampholytes and betaines, the latter being present in solution as zwitterions. Ampholytes are amphoteric electrolytes, ie, compounds that have both acidic and basic hydrophilic groups and thus behave acidic or basic depending on the condition. Betaines are compounds with the atomic group R 3 N + -CH 2 -COO - which show typical properties of zwitterions.
  • gemini surfactants are so-called gemini surfactants. These are generally understood as meaning those compounds which have two hydrophilic groups and two hydrophobic groups per molecule. These groups are usually separated by a so-called “spacer”. This spacer is usually a carbon chain that should be long enough for the hydrophilic groups to have have enough distance to act independently of each other. Such surfactants are generally characterized by an unusually low critical micelle concentration and the ability to greatly reduce the surface tension of the water. In exceptional cases, however, the term gemini surfactants is understood to mean not only dimeric but also trimeric surfactants.
  • Suitable gemini surfactants are, for example, sulfated hydroxy mixed ethers or dimer alcohol bis- and trimer tris sulfates and ether sulfates. End-capped dimeric and trimeric mixed ethers are characterized in particular by their bi- and multi-functionality. Thus, the end-capped surfactants mentioned have good wetting properties and are low foaming, so that they are particularly suitable for use in machine washing or cleaning processes.

  • As optical brighteners three different brighteners were tested: in a first batch FB-71 (from Aako), in a second batch leucophore BSB (from Clariant) and in a third batch Tinopal CBS-X (from BASF).
  • the dye transfer inhibitor not recognize the optical brightener as a "dye" and prevent it from being absorbed onto the fabric.
  • FIG. 4 It can be seen that in the separate use of color transfer inhibitor in component 1 of the detergent and optical brightener in component 2 of the detergent in each case a significant brightening of the laundry can be achieved.
  • the color transfer inhibitor does not appear to bind this brightener and the whiteness is not affected after 15 washes.
  • component 1 was used as described in Example 1, as a booster, a composition was used according to Example 3, which was also added as optical brightener Tinopal CBS-X in an amount such that 0.15% or 0.073% final concentration achieved in the total detergent were.
  • a commercially available heavy duty detergent was used. It was found that the component detergent does not adversely affect the colors of the laundry, it came to no further color damage or color shift of the coloreds, while the use of heavy duty detergent was a significant fading of the colors after 15 washes to recognize.
  • FIG. 5 It can be seen that the efficiency of the color transfer inhibitor is not affected in the presence of the optical brightener.
