The present invention relates to improved bleaching compositions, which essentially does not contain the amounts of the components.

In recent years there has been an increasing development of bleaching catalysts for the removal of contaminants. Recently discovered ability of certain catalysts to effectively whiten in the absence of additives sources peroxido, was the subject of several studies, for example: WO9965905; WO0012667; WO0012808; WO0029537 and WO0060045.

The shelf life of the product can be interpreted as the period of time during which the product retains the desired quality. In many cases, long shelf life is the determining factor for the commercial success of the product. A product with a short shelf life have to produce in small batches and quickly sell to consumers. The owners of trademarks with a short lifespan you need to remember that the consumer uses the product within its lifetime, otherwise the consumer may be forced to replace this product with a product of a different brand. Similar product with a long lifetime can be produced in larger volumes, and to create reserves for a longer period, and therefore the owner of the brand may not care about the issue, how long the consumer keeps the product.

The aim of the present invention is costaricensis, whitening under the action of air, with improved storage properties.

Applicants have found that some of the perfume components are decomposed by themselves and, over time, reduce the activity of the bleaching catalysts. It was found that the stability of the whitening composition essentially containing no peroxide oxygen or bleach-based peroxy-groups or peroxyl-generating groups, can be improved by careful selection of some components of perfume compositions. The present invention is applicable to both granular and liquid formulations. However, the present invention is particularly applicable to liquid bleaching compositions.

The present invention offers a whitening composition comprising a perfume, which does not reduce the activity of the catalyst based on a transition metal and operates as described below.

The present invention provides a liquid whitening composition containing

liquid whitening composition, including:

(a) an organic substance which forms a complex with the transition metal, for bleaching of the substrate under the action of atmospheric oxygen, and whitening composition after adding to the water environment creates water whitening environment that does not contain bleach - percenage oxygen or system on the basis of p is maxigrip or generating peroxyl group;

(b) from 0.001 to 3 wt.% perfume compositions; and

(C) carriers for balance and additional ingredients to 100 wt.% from all of the whitening composition,

in which the whitening activity of the whitening composition more at least 10 times compared with the same bleaching composition, in which the perfume composition is present in a molar equivalent of citronellal, after a period of storage at 37°C for 14 days, and whitening activity was determined by bleaching activity of the catalyst based on transition metal with respect to the Acid Blue 45 in the presence of hydrogen peroxide.

Alternatively, as a means to measure the activity of the catalyst can be used in beta-carotene. In cases where the catalyst based on transition metal exhibits a measurable activity only in the bleaching under the action of air, but not added amounts of the components, in particular hydrogen peroxide, beta-carotene can be used to assess the relative activity of the catalyst based on a transition metal.

The ratio of activities is at least 12, most preferably 15.

Preferred perfume components can be selected from the group consisting of alpha-damascone, Delta damascone, Iso E super, cinnamic aldehyde, gexi the cinnamic aldehyde, butylcatechol aldehyde, benzaldehyde, anisic aldehyde, linalool, tetrahydroindole, undecalactone, geraniol, nerol, citronellol, citral, rose oxide, geranylacetone, citronellate, coumarin, minalrestat, geranylated, citronellal, cinnamic acid nitrile and citronella, amiloride aldehyde, methylanthranilate, diethylaniline, methyl-nacetylanthranilic, Difenoxin, Verdox, benzoylacetate, diol, Orange Cristals, Peonile, Clonal, limonene, camphor, anthranilate, diisobutylphthalate, Verdyl Acetate, pinane, Veloutone, alpha methylionone and damascenone.

The term "does not contain peroxide bleach or whitening systems on the basis of peroxyl groups or generating peroxyl group" should be understood in the sense of the present invention. Preferably, the composition contains less amounts of the components. Preferably, the bleaching composition contains less than 1 wt.% nagkalat or hydrogen peroxide, or its source, it is preferable that the bleaching composition contains less than 0.3 wt.% nagkalat or hydrogen peroxide, or its source, most preferably, the bleaching composition did not contain nagkalat or hydrogen peroxide, or its source. In addition, it is preferable that the content of alkylhydroperoxide in otbelivayushe composition is, containing a ligand or a complex of the present invention, was minimized.

The present invention covers a method of bleaching a fabric base using the compositions of the present invention. The method includes the stage of processing of the fabric bleaching composition in an aqueous medium, rinsing the cloth and drying.

The present invention also includes industrial packaging with instructions on its application.

Other carriers and additional ingredients

Catalyst air bleaching can be used in the detergent composition, specifically designed for whitening pollution that represents a second aspect of the invention. In this sense, the composition is a surfactant and, optionally, other conventional ingredients of detergents. The invention in its second aspect provides an enzymatic detergent composition which contains 0.1 to 50 wt.% one or more surfactants in the calculation on the entire detergent composition. This system of surface-active substances, in turn, contains 0-95 wt.% one or more anionic surfactants and 5-100 wt.% one or more nonionic surfactants. In addition, the system of surface-active substances may contain amphoteric or zwitterionic surface-active compounds, but this is usually undesirable because of their high cost. Enzymatic detergent composition of the present invention is usually used diluted in water with a concentration of 0.05-2%.

In General, non-ionic and is and anionic surfactants for the system of surfactants can be chosen from surface-active substances, described in “Surface Active Agents” vol. 1, Schwartz and Perry, Interscience 1949, vol. 2 Schwartz, Perry and Berch, Interscience 1958, in the current edition of “McCutcheon''s Emulsifiers and Detergents”published by Manufacturing Confectioners Company or in “Tenside-Taschenbuch”, H. Stache, 2ndEdn., Carl Hauser Verlag, 1981.

Suitable nonionic detergent compounds include in particular the reaction products of compounds containing a hydrophobic group and a reactive hydrogen atom, for example aliphatic alcohols, acids, amides or alkyl phenols with acceleratedly, including ethylene oxide, or pure, or mixed with propylene oxide. A particular case of a non-ionic detergent are condensates With6-C22alkylphenol with ethylene oxide composition 5-25 EO, i.e 5-25 units of ethylene oxide per molecule and the condensation products of aliphatic primary or secondary linear or branched alcohols With8-C18with ethylene oxide, generally composition 5-40 SW.

Suitable anionic detergent compounds are usually water-soluble alkali metal salts of organic sulfates or sulfonates containing alkyl radicals of from about 8-22 carbon atoms, the term "alkyl" includes alkyl portion of higher acyl radicals. Examples of suitable synthetic anionic detergents are alkyl sulphates of sodium and potassium, especially those produced by sulfonation of higher alcohols With8-C obtained, for example, from solid animal fats or coconut oil; C9-C20alkylbenzenesulfonate sodium and potassium, in particular linear secondary10-C15alkylbenzenesulfonate sodium; and sulfates simple alkylglycerol esters, in particular esters of higher alcohols derived from solid animal fats or coconut oil and synthetic alcohols derived from petroleum. The preferred anionic detergents are11-C15alkylbenzenesulfonate sodium and12-C18the sodium alkyl sulphates. You can also use a surfactant of the type described in EP-A-328177 (Unilever), which is resistant to salting out, surface-active alkylpolyglycoside described in EP-A-070074, and alkylhalogenide.

The preferred surfactant system is a mixture of anionic and nonionic detergent active compounds, in particular groups and examples of anionic and nonionic surfactants discussed in EP-A-346995 (Unilever). Particularly preferred system of surface-active substances, which is a mixture of salts of alkaline metal sulfate primary alcohol

With16-C18and ethoxylates, primary alcohol With12-C15containing 3-7 SW.

It is preferable to use nonionic surfactant in to the icestar more than 10, for example 25-90 wt.% surfactants. Anionic surfactants can be present in the surfactant system, for example, in amounts of about 5-40 wt.%.

Expert it is clear that some peroxyl connections may happen to be in the composition, but nevertheless most preferably, the bleach composition of the present invention contains less than 1%, preferably less than 0.1%, most preferably less than 0.01%, peroxyl compounds. Such random amounts of compounds are mainly hydroperoxides formed during avtookislenie surface-active substances.

The composition may further contain enzymes as found in WO 01/00768 A1, page 15, line 25 to page 19, line 29, and the contents of which are incorporated herein by reference.

Such optional ingredients such as fillers, polymers, and other enzymes may also be present in the composition as specified in WO0060045.

Can also have an optional ingredients in the form of suitable fillers detergents, as found in WO0034427.

The composition of the present invention can be used for washing Laundry, cleaning hard surfaces (including cleaning toilets, working surfaces, kitchens, floors, dishwashers and so on). It is to known to specialists, bleaching compositions are also used for wastewater treatment, for bleaching of pulp in paper production, in the leather industry, to prevent flow of ink, in the processing of food, for bleaching of starch, sterilization, as brighteners for oral hygiene and/or disinfecting contact lenses.

In the context of the present invention whitening should be understood mainly as discoloration spots or other substances attached to the substrate or related. Remember, however, that the present invention can be applied wherever it is necessary to remove and/or neutralize with the reaction of oxidative bleaching any smelly or other undesirable components attached to the substrate, or otherwise associated with it. Moreover, in the context of the present invention whitening should be understood as a process characterized by any mechanism that does not require lighting and activating the light.

The whitening composition

The present invention is particularly applicable to liquid compositions, as in the liquid composition in contrast to the solid heterogeneous mixture achieves a more intimate contact between the individual components and, therefore, it is more sensitive to degradation as a result of interaction of components.

There are many who promyshlennykh liquid formulations for detergents and conditioners for rinsing or other liquid products, which can be improved by giving them a bleaching ability. As will be obvious to the specialist, the present invention is applicable to known and emerging liquid compositions.

The concentration of catalyst in industrial bleaching composition is in the range of 0.0001 to 0.6 wt.%, preferably of 0.001 to 0.15 wt.%, most preferably 0.01 to 0.1 wt.%. The authors found that the optimum concentration of catalyst in industrial bleaching composition is 0.03-0.09 wt.%.

The present invention applies to both isotropic and complex liquid compositions and formulations, which will be briefly discussed below. Some isotropic compositions as "microemulsions", which are transparent and thermodynamically stable in a given temperature interval. "Microemulsion" can be emulsion-type water-in-oil or oil-in-water. Some liquid formulations are microemulsion that are not transparent and not isotropic. It is believed that the metastable emulsion. Concentrated transparent compositions containing substance for softening fabrics were disclosed in WO 98/08924 and WO 98/4799, both Procter & Gamble. These compositions contain conditioners for fabrics that are biodegradable. However, both disclosed compositions contain solvents, miscible with water, which do not form a microemulsion-type water wt is e". Transparent compositions with fabric conditioners were also disclosed in EP 730023 (Colgate Palmolive), WO 96/19552 (Colgate Palmolive), WO 96/33800 (Witco Co.), WO 97/03170 (Procter & Gamble), WO 97/03172 (Procter & Gamble), WO 97/03169 (Procter & Gamble, US 5492636 (Quest Int.) and US 5427697 (Procter & Gamble). The liquid compositions of the present invention may contain, for example, monoethoxylate Quaternary compounds; AQAs and bis-AQAs; cationic amides, cationic esters; amino/diamino Quaternary compounds; glutamine; aminoxide; the ethoxylated polyethylenimine; improving polymers in the form of polymers on the basis of linear amines, for example bis-hexamethylenediamine; polyamine, for example polymers THETA, TERA or RE.

The liquid may be contained in dry spirits, as shown in WO02/068577.
