Abstract (en)
[origin: WO9963042A1] The invention aims at solving the problem of hydrogen peroxide wastage when the agent is poured on dirty textiles and the increased oxidative load on the textile when pretreatment agents containing peroxide are used in an aqueous bleaching agent serving as laundry pretreatment agent. This is substantially achieved by an agent containing 0.2 to 25 % by weight of hydrogen peroxide, complexing agents for heavy metals in a quantity of up to 5 % by weight, surfactants in a quantity of up to 15 % by weight, free-radical scavengers in a quantity of up to 0.1 % by weight and water in quantities ranging from 55 to 90 % by weight and a polysaccharide thickening active substance in quantities such that the substance has a viscosity in the range of from 200 mPa.s to 5,000 mPa.s at 20 DEG C and at rpm 20 (Brookfield rotational viscometer) and a viscosity at rpm 5 (Brookfield rotational viscometer) that is at least 1.5 higher than at rpm 50.
