  • the present invention relates to an aqueous bleaching agent concentrate based on hydrogen peroxide, which in water-diluted form is particularly suitable for use as a laundry pretreatment agent, but also as a detergent or detergent additive in conventional washing processes, its use as a laundry pretreatment or laundry detergent, and a washing process using such Means.
  • liquid detergents and cleaning agents are very popular with consumers. These advantages are also offset by technical difficulties that have to be overcome in the manufacture and storage of the agents. In particular, the formulation of a storage-stable aqueous detergent preparation containing bleach is not trivial.
  • liquid concentrates that are diluted down to their dosing concentration with water before use. This offers advantages in particular when transporting the agent, but places increased demands on the production, since correspondingly larger active substance concentrations have to be incorporated into the liquid formulation.
  • pre-treatment 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. Through intensive and longer exposure time of the peroxide-containing agent, an improved removal of the bleachable stains from the textile is achieved if the textile is subsequently subjected to a household washing process, in addition to machine washing processes, so-called hand washing can also be used.
