Definitions
- the present invention relates to an aqueous bleaching agent based on hydrogen peroxide, especially for use as laundry pretreatment agents, but also as Additive in conventional washing processes is suitable for its use as Laundry pretreatment agent and a washing method using such Agent.
- Common liquid peroxide-containing pretreatment agents are relatively low-viscosity means that they generally have viscosities not exceeding 200 mPa.s. They contain alongside the peroxide is usually water and surfactants, which improve wettability the stains should apply when applying the agent. Due to the high network effect and the low viscosity of the agent causes the product to run badly on the treated textile, so that even with careful application of the agent in all Usually a much larger area than the actual stain is wetted. this leads to that part of the peroxide applied to the textile does not bleach the Soiling is available, 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 applied higher shear forces.
- the change in viscosity is usually not directly proportional the change in acting shear forces, but the viscosity increases with decreases in shear force in the low shear range more than in the high Shear area. This property can be checked experimentally by: measures viscosity under various shear conditions. One way to do this offers a common rotary viscometer at different speeds the spindle.
