IP AUSTRALIA Zt., RECEIVED S2 7 NOV 1998
SMELBOURNE
Q:APER1MJC%773q7*94.331 2711/98 Multi-component Bleaching System This invention relates to a new multi-component bleaching system for use with detergent substances. Particularly in the low-temperature range the traditional bleaching systems in domestic detergents are unsatisfactory.
Below a washing temperature of 60 C the standard bleach H202/sodium perborate/sodium percarbonate has to be activated by the addition of chemical bleach S activators like TAED and SNOBS. There is also a quest for better biologically degradable, bio-compatible and low-dosage bleaching systems for low-temperature wash. Though enzymes are already in technical use for protein starch and dissolving 10 of grease as well as the treatment of fibres during the washing process, there is not yet any enzymic principle available for detergent bleach.
In WO 91/05839 the use of various oxidising enzymes (oxidases and peroxidases) to present dye transfer is described. Peroxidases are known to be able to "decolour" various pigments (3-hydroxy-flavour and betalain by menas of horse-radish peroxidase, carotene by means of peroxidase).
The Patent itself describes the decolouring (also termed bleaching) of the textile dyes in the liquor/bath and removed from the wash (conversion of a dyed substrate into an undyed, oxidised substance). The enzyme should possess the advantage of only decolouring dissolved dye in contrast with e.g. hypochlorite, which attacks the dye on or in the tissue with hydrogen peroxide or an appropriate precursor on hydrogen peroxide generated in situ being involved in the catalysis of the decolouring. The i P:AOPER\Mal\2M)I\94161-9r spe 1.doc-4/n2)2 -2enzyme reaction can be partly increased by additional oxidisable enzyme substrate e.g.
metallic ions like halogen ions like Cl- and Br- or organic phenols like p-hydroxycinnamic acid 2,4 dichlorophenol. This demands the formation of short-lived radicals or other oxidised conditions of the added substrate which are responsible for the bleach or another modification of the dyed substance.
In US 4 077 768 the use of iron phorphin, haemin chloride or iron phtalocyanines or derivatives together with hydrogen peroxide to prevent dye transfer is described. These substances are rapidly destroyed with a surplus of peroxide, and so care must be taken with the formation of hydrogen peroxide.
One of the aspects of this invention, therefore, is to make available a multi-component 0* bleaching system for use with detergent substances which stands out from the state of the art in terms of biological degradability, bio-compatibility, dosage and bleaching efficiency.
In order to overcome some of the problems faced in the prior art the present invention provides a multi-component bleaching system consisting of oxidation catalysts and suitable oxidising agents as well as aliphatic, cyclo-aliphatic, hetero-cyclic or aromatic compounds having NO, NOH or HNOH groups which even bleaches stubborn dirt such 20 as coffee and tea stains.
The special feature of the invention is the novel use of a mixture of enzyme and mediator to bleach dirt in tissue (comparable to conventional bleaching systems). The enzyme reaction from the mediator causes a "bleach active intermediate" able to attack dirt, even when it is not an enzyme substrate.
Apart from this "unspecific" attack an oxidation is probable, because of specific enzymes, of dirt generally regarded as problem stains from fruit, tannin from tea, coffee and red wine.
In another case a stabilised per-acid precursor can, through bonding to an enzyme substrate, be "activated" by means of the enzyme reaction, and so the bleaching effect ,A S/k can take place due to the high oxidation potential of the released per-acid.
P:\OPER\Mal\2001\94161-98 spc l.doc-(4)2A)2 -3- Oxidoreductases are used by preference as catalysts for the invention. The main ones are oxidases, peroxidases, lignin-peroxidases, manganese peroxidases, laccases.
Preferred are enzymes extracted from fungi, bacteria, animals and plants. Also usable are parts of plants and animals such as cell cultures.
White-rot fungi in particular have proved their worth as fungi for enzyme extraction.
Coriolus versicolor is the special one.
Also for use are modified enzymes, enzyme components, prosthetic groups or haem groups and compounds containing haem groups. The last-named are mimic compounds.
Mimic substances are those that, as in the case of laccase simulation, represent copper complexes, imitate the effect of catalytically active prosthetic groups and so can carry out oxidation with the usual laccase substrates.
The present invention also utilises aliphatic, cyclo-aliphatic, heterocyclic or aromatic compounds having NO, NOH and HNOH groups, which may include one or mixtures of Nhydroxy, oxime, N-oxide, N-dioxide, hydroxylamine and hydroxamic acid based compounds and their derivatives. Also the bleaching system may contain phenolic and/or 20 non-phenolic compounds with one or more benzene nuclei. All these compounds serve 0. as so-called mediators.
:.:oe The invention oxidising agents are air, oxygen, H 2 0 2 organic peroxides, sodium perborate and/or sodium percarbonate. Oxygen can also be generated in situ through H 2 0 2 catalase or similar systems, or H 2 0 2 may be generated in situ from GOD glucose or similar systems.
Also preferred is a cation-forming multi-component bleaching system containing metallic salts. Cations to be used are Fe2+, Fe3+, Mn2+, Mn3+, Mn4+, Cu+, Cu2+, Ti3+, Cr4+, Mg2+ and A13+.
The bleaching system can also contain polysaccharides and/or proteins. Polysaccharides T'S to look for are glucan, mannan, dextran, laevan, pectin, alginate, -4gum and/or a few of the polysaccharides formed from fungi or produced in mixed culture with yeasts. Proteins can be gelatine and albumin.
There may also be added simple sugar/monosaccharide, oligomer sugar, amino acids, PEG, polyethylene oxides, polyethylenimines and polydimethylsiloxanes.
The invention multi-component bleaching system may be used in combination with well-known active detergent additives.
The bleaching system shows its effect in a pH of 2-12 -preferably 4-10- and at temperatures of 10 60* C preferably 20 40" C.
Example 1: 10 Effect of laccase/mediator system on (BC2) coffee-stained standard cotton Cloth/rag Example: In 100 ml washing-solution (in 300 ml Erienmeyer flask) one cloth/rag each (5 x 5 cm) is incubated at 40" C for 40 min. with reciprocal agitation (120 cpm).
0 Before the start of incubation the washing solution is subjected to ten minutes of adjustment to temperature. The solution is prepared with STW (Standard Tap Water S 15 at 140 dH. The enzyme dosage is 200.000 IU laccase from coriolus versicolor/100 ml, the mediator dosage 200 mg hydroxybenzotriazole/100 ml).
After the "washing-lye/buck" has been poured off, it is filled up with a cold, strong jet of water 3 x and poured off.
Table 1 shows the results compared with a commercial liquid detergent (without bleaching system) and a heavy-duty detergent (with bleaching agent).
Example 2: Effect of laccase/mediator system on (BC3) tea-stained standard wool cloth/rag.
In 100 ml washing-solution (in 300 ml Erlenmeyer flask) one cloth/rag each (5 x 5 cm) is incubated at 40" C for 40 min. with reciprocal agitation (120 rpm).
Before the start of incubation the washing solution is subjected to ten minutes of adjustment to temperature. The solution is prepared with STW (Standard Tap Water at 140 dH. The enzyme dosage is 200.000 IU laccase from coriolus versicolor/100 ml, the mediator dosage 200 mg hydroxybenzotriazole/100 ml).
After the washing-lye/buck" has been poured off, it is filled up with a cold, strong jet of water 3 x and poured off.
The results are shown in Table 2.
10 Example 3: An experiment was carried out in accordance with Example 1. The mediator was acetoxybenzotriazole. The result is shown in Table 3.
