     The invention relates to bleaching agents used for detergents and cleaning agents that are used at low temperatures, as well as for bleaching paper and textile fibers. Inorganic peroxide compounds, especially sodium borate and sodium carbonate peroxohydrate, are known to be an integral part of numerous bleaching agents. Such peroxides are used in standard detergents and cleaning agents, and these oxygen bleaching agents at temperatures below 80 ° C have a very weak whitening ability. Because of this, it is not enough to use only such means for bleaching heat sensitive fabrics from artificial fibers or fabrics with natural alloys and fibers. Best selection at 20s -. can be achieved, as is known, with the use of organic peroxides, especially organic peracids. The introduction of such compounds into powder-like cleaning and cleaning agents is very difficult. It is also known that inorganic peroxide compounds, due to the addition of activators, especially re-active organic N-acyl and O-acyl compounds, become effective means for bleaching — at temperatures as low as 80 ° C and have an antimicrobial effect. Suitable activators are, for example, tetraacetyl glycoluryl, tri-acetyl cyanurate, tetra-acetyl-ethylenediamine, pentaacetylglucose and acetylsalicylic acid. Such compounds react in aqueous solution with inorganic peroxides to form organic peracids, for example, peracetic acid, which already at low temperatures have a horse whitening ability. Activators for inorganic peroxides can be more easily incorporated into conventional detergents and cleaning agents. However, to obtain storage-stable detergents and cleaning agents or other products containing peroxides, it is necessary to create a shell around the activators with the help of suitable components to eliminate premature reaction with inorganic peroxide compounds, as well as hydrolysis due to the effect of moisture on powdered products. A significant enhancement of the bleaching effect at low temperatures can be achieved by using transitional salts of salts in combination with oxidation-resistant chelating compounds in bleaching agents containing activators. Mixtures of bleaching agents are known, which, in addition to inorganic peroxides and activators, contain water-soluble metal salts or oxides with the order number 24-29 in combination with a chelating agent that is stable under given oxidizing conditions, which has the first complex formation constant with a transition metal ion at 20 C, the decimal logarithm of which is 2-10 (US Patent 3,532,639). Pyridine-2-carboxylic acid, pyridine-2,6 dicarboxylic acid, picolinic acid, quinodic acid, 1,10-phenanthroline and 2,2-dipyridyl are used as suitable chelating compounds. Known oxidation-resistant complexing agents, for example ethylene diamine tetraacetic acid, the complexation constant of which with metal ions above 10, are unsuitable for this purpose. Preferred chelating compounds are 1,10-phenanthroline, picolinic acid and 2,2-pyridyl. Using the blends of bleaching agents described, especially when using soluble cobalt salts in combination with the preferred chelating compounds in a molar ratio of 1: 8 to 1:10, a significantly improved activator perborate is achieved at temperatures of about 50 ° C. . The uncontrolled and almost non-reproducible effect of the remaining components of the bleaching, respectively washing bath negatively affects the complexation of the given components and disrupts the catalytic process. Therefore, it is necessary to use the chelating compound in excess. In addition, it is necessary to use chelating compounds resistant to oxidation (which leads to higher prices for bleaching agents. The potential pollution of the environment with heavy metal containing wastewater prevents the widespread use of known bleaching agents. It is known to use combinations of water-soluble copper salts with chela-forming compounds, such as, for example, ethylenediaminetetraacetic diethylenetriamine pentaacetic, ethylaminodiacetic, aminotriucetic and hydroxyethylaminodiocetic acid (French patent 91876). These combinations enhance the whitening effect of activator perborate systems at low temperatures. The disadvantage of this method lies in the fact that the dosage of the components of the coke metal and chelate forming compound, especially in powdered products, is difficult, and the uncontrollable effect on the complexation in the bleaching liquid disrupts the catalytic process. In addition, uncomplexed honey ions catalyze the decomposition of peroxide compounds and reduce bleaching action. The aim of the invention is to create a bleaching agent for detergents and cleaning agents, which has, especially at low (20-40 ° C) washing temperatures, a strong bleaching effect with an antimicrobial effect, is much cheaper to obtain than conventional means, not causes twisted fiber damage compared to known peroxides. means for bleaching at approx nenii at reflux temperature, and both turns the fouling environment srbd This aim is achieved such that the bleaching composition comprising, sodium perborate and activator comprises an activator penta acetyl glucose or acetylsalicylic acid or tretraatsetiletilan diamine or tretraatsetilglikoluril further complex compound of the general formula Mjh.X, 5de Mj - Cu, Ni or Zn; L is ethylenediamine; X is a nitrate anion; n - 2 or 3, with the following ratio of components, May. %: Proposed ac28, 57-48.78 tivator Complex compound of general formula (i) 2.44-2.86 Sodium perborate Up to 100. Studies have shown that when using the described bleaching agents as compared with conventional peroxide bleaches, there is no increased damage to the fibers of the treated fabrics. Compared with the known bleaching systems, which consist of a single component activator, an inorganic peroxide compound, a transition metal salt, and an oxidation resistant chelating compound, the previous bleaching composition has several advantages. It is possible to use chelate forming components, which in the free state are not sufficiently stable to oxidation. Therefore, simple in their chemical structure and cheap compounds are also fundamentally suitable. When using the proposed bleaching agent, uncontrollable effects in the detergent bath, respectively bleaching, on the formation of chelates are excluded, which is a prerequisite for an optimal catalytic effect. Redox processes at the central atom of the complex are obviously only of secondary importance for the catalytic effect of the metal chelates used. For example, the complexes of ethylenediamine with nickel, copper and zinc do not show a significant difference in terms of catalytic activity. Thus, the choice of suitable metal compounds is not limited to metals with the serial number 24-29f. It is possible to use all metals capable of forming complexes with suitable ligands. The better dosing of certain metal chelates in the bleaching agents according to the invention also makes it possible to minimize the contamination of wastewater. The incorporation into detergents and cleaning agents can be carried out in a known manner: the metal chelate and the activator are coated in suitable form to avoid premature hydrolysis of the activator or reaction with the inorganic peroxide compound comprising ms of the substance during storage. It is also possible to coat the inorganic peroxide compound and metal chelate. The same effect during the washing process can be achieved if a mixture of metal activate and metal chelate is added to the washing bath, which already contains inorganic peroxide compounds. Example 1 Bleaching agent for the introduction into the cleaning media will be obtained, wt.%: Zn (en)} (N0) 2 2/44; enacetseglucose 48.76; perborate 48.78. To obtain a bleaching agent at low temperatures, 20.5 hours of bleaching medium and 79.5 hours of ordinary perawate detergent are mixed. Example 2 Bleaching medium containing, wt.%: (En) j (N0) 2 2.44; acetylsalicylic acid 48.78; perborate 48.78 / is mixed with perborate-free detergent in the same ratios as in example 1.
    Example 3. Bleaching agent contains, wt%: Ni {en) s (NO) 2, 86; tetraacetyl glycoluryl 28.57; perborate 68.57,
    To obtain a detergent with a high whitening effect at ny temperatures, 17.5 parts of bleaching agent and 82.5 parts of non-perborate detergent are mixed.
    Example 4. Bleaching agent contains, wt%: {N1 (en) j (KO) 2 2.86; tetraacetylethylenediamine 28.57; perborate 68.57, - is mixed with perforate-free detergent in the same ratios as in example 3.
    The effectiveness of the bleaching agents is determined under practical washing conditions using the formulations of examples 1-4.
    For testing, a Scorostaster type laboratory washing machine (washing time 30 min, concentration 5 g / l, bath module 1:80) is used.
    The fabric being tested is cotton fabric dyed with sulfurous green (B), which corresponds in its sensitivity to oxidizing agents with colored a1-media green BTN fabric,
    For the evaluation, the difference between the measured luminance factors (4R) before washing and after the 2nd washing is taken and the results are compared with the values obtained without adding cheats to metsplov.
