Definitions
- the present invention relates to a bleaching system comprising an enzyme producing hydrogen peroxide and a transition metal compound, and to the use of this system as a bleaching component in the detergents and cleaning agents.
- Enzymatic bleaching compositions containing a hydrogen peroxide generating system are well known in the art. For example, those are described in patent applications EP 553 608, EP 553 607, EP 538 228, EP 537 381 and DE 20 64 146.
- Such enzymatic bleaching compositions can be used, for example, in detergent formulations for washing textiles, in which the highest possible bleaching effect at a low temperature is desired.
- the enzymes catalyze the reaction between the dissolved oxygen and the substrate.
- a bleach activator is usually used.
- One of the most commonly used bleach activators is tetraacetylethylenediamine (TAED), which forms peracetic acid by reaction with the hydrogen peroxide, the peracetic acid being the actual bleaching agent.
- TAED tetraacetylethylenediamine
- Bleaching catalysts in the form of transition metal complexes for example manganese (Mn) and / or iron (Fe), are known from the prior art and are described, for example, in European patent applications EP 0 458 397, EP 0 458 398, EP 0 544 519 and EP 0 549 272. In combination with hydrogen peroxide, they form a very strong oxidation system.
- transition metal complexes for example manganese (Mn) and / or iron (Fe)
- Mn manganese
- Fe iron
- transition metal complexes have the disadvantage that they destroy not only the bleachable stains but also the dye which is on the fiber. In some cases, the fiber can be destroyed, known as pitting.
- the object of the present invention was to develop a catalyst system which is effective at low temperature without the external addition of oxygen carriers and which reacts with bleachable stains which are on the fiber or in the washing liquor and thus lead to the destruction of the stains.
- the bleaching system should also react with free dye molecules in the wash liquor, but the color on the textile should remain, i.e. a reaction with paint on the textile or with the textile fiber should be avoided.
- the bleaching system according to the invention gives very good bleaching performance at low washing temperatures, in particular between 15 and 55 ° C.
- the bleaching system continuously forms H 2 O 2 and thus achieves a uniform bleaching performance without causing fiber damage. Although it reacts with the bleachable stains on the fiber and in the wash liquor and also with free dye molecules in the wash liquor, it does not react with textile dyes on the textile.
- the system is essentially inactive due to the thermal enzyme instability. Because of the high solubility of the enzymatic system according to the invention, deposits on the fibers can be minimized. No deposits of the metal complex bound to the enzyme were found on a piece of laundry.
- transition metal compounds used in the form bound to the enzyme according to the invention are preferably copper, manganese, iron, cobalt, ruthenium and / or molybdenum compounds, since with these compounds the bleaching reaction can be controlled particularly well and within certain limits.
