Definitions

  • the present invention relates to an aqueous bleaching agent based on hydrogen peroxide, which is particularly suitable for use as a laundry pretreatment agent, but also as an additive in customary washing processes, its use as a laundry pretreatment agent and a washing process using such an agent.
  • stains In order to remove stubborn stains, so-called stains, from textiles, they are often treated with special pre-treatment agents before the actual washing process.
  • peroxide-containing pretreatment agents are generally used. Because of the then eased application conditions, such pretreatment agents are normally liquid and are poured onto the stain directly or, if appropriate, after dilution with water.
  • a household washing process which, in addition to machine washing processes, can also be used by hand washing.
  • Usual liquid peroxide-containing pretreatment agents are relatively low-viscosity, which means that they generally have viscosities not exceeding 200 mPa.s.
  • they usually contain water and surfactants, which are said to improve the wettability of the stains when the agent is applied.
  • the high wetting effect and the low viscosity of the agent cause the product to run strongly on the treated textile, so that even if the agent is applied carefully, a much larger area is usually wetted than the actual stain. This means that part of the peroxide applied to the textile is not available for bleaching the soiling, but is wasted, so to speak, because it is not in appropriate direct contact with the stain.
  • Structural viscosity is understood here to mean the effect that the liquid agent has a higher viscosity when exposed to low shear forces than when exposed to higher shear forces.
  • the change in viscosity is not directly proportional to the change in the shear forces, but the viscosity increases with shear forces. decreases in the low shear range more than in those in the high shear range. This property can be checked experimentally by measuring the viscosity under different shear conditions. One way of doing this is to use a conventional rotary viscometer at different speeds of rotation of the spindle.
