Description

Agent with deodorizing effect For the production of deodorizing active preparations and hygienic products, substances have already been used known as disinfectants. So far 2,2'-Dioxy-3,5,6,3 ', 5', 6'-hexachlorodiphenylmethane, quaternary ammonium compounds, organic mercury compounds, phenol derivatives with and without halogen substituents, bacterially effective derivatives of amino acids used for this purpose.

These substances have the disadvantage that their effect is in the presence of protein, e.g. B. of blood, is largely destroyed.

Furthermore, it is known to chlorophyll, but its effects are great is controversial, or purely absorptive agents such as gels made of aluminum or Silicon oxide hydrates, or salts of polyvalent metals such as aluminum, zinc, tin, Zircon can be used in both inorganic and organic bonds. Even Complex compounds of these metals, such as trisodium aluminum pentahydroxy chlorolactate and sodium zirconium lactate, have been used to produce a deodorant effect used. It was found, however, that the effect of these agents is through the penetration is reached in the fine sweat capillaries, with the colloid protein in the sweat ducts precipitated and coagulated into an insoluble hydrophobic substance. It deals So there is a protein precipitation that prevents secretion and damages the epithelium, whereby due to the clogging of the apocrine glands the further release of sweat is prevented. Obviously, this achieves that an excessive There is no perspiration, but at the same time there is also the risk of skin damage conjured up. So there have been used so far means by their sweat containment Effect deodorizing, or disinfectants, their deodorizing effect is based on the fact that they are the bacterial skin flora, which the decomposition of sweat caused, kill and thereby suppress body odor.

There were now in the compounds of metals, preferably polyvalent Metals, found with 1,3-diketones substances with deodorizing effects that the Do not have disadvantages of the previously known deodorants, d. H. in present of blood remain effective, the sweat capillaries do not clog, the skin flora do not kill and do not cause skin damage. The effect of the new Means is presumably based on the fact that they are only involved in the metabolism of bacteria and other microorganisms, e.g. B. mushrooms, intervene and thereby the formation prevent unwanted waste products. Even if with subliminal dosage the growth of bacteria is not or only incompletely suppressed, can but avoid the formation and excretion of undesirable odor-causing substances. It is therefore often only a small dose is sufficient. With a suitable dosage the symbiotic flora is fully preserved, which is very good for health reasons is desired, e.g. B. to maintain the mucosal flora.

The invention relates to new agents with deodorant effect that in various forms z. B. as fibers or fibrous materials, ointments, powders, liquids, Soaps can be present and which are characterized by the fact that they are compounds of metals, preferably polyvalent metals, with 1,3-diketones as an active ingredient contain.

The metal compounds according to the invention are probably complex compounds, that by bonding the metal atom to an enolic hydroxyl group of the 1,3-diketones have arisen. Suitable metals are, for example, copper, nickel, cobalt, calcium, Zircon, zinc, tin, aluminum, cadmium, cerium, beryllium, magnesium and mercury. The 1,3-diketones which can be used for the production of the metal compounds can be of any kind. They are based on the type of acetylacetone and can at the carbon atoms different radicals, such as substituted or unsubstituted alkyl, Aryl or acyl groups. The 1,3-position of the ketone groups is important since 1,2- or 1,4-diketones do not show the desired properties. For a good Effectiveness of the metal compounds is a prerequisite that they are in water, at least to a small extent, are soluble. The application of the active ingredients on or in the practical raw materials used, such as fibers or fibrous materials, ointments, powders, liquids, Soaps or the like. Can be used in any known manner, for. B. by flotation, Soaking, spraying, wetting or printing using a solution of the active ingredient in water or an organic solvent.

Example 1 500 g of isooctanedione zirconate available. through implementation of isooctanedione and zirconium acetate in well-known Way, be at the production of cellulose wadding in alcoholic solution in the liquor of 100 kg pulp incorporated. Sanitary napkins made from them also show practically complete deodorization after long periods of wear.

Example 2 1 part of heptanedione zirconate obtainable by reaction of heptanedione and zirconium acetate, is dissolved in 1000 parts of ethyl alcohol (6Q ° toig) and lightly perfumed at will. If the armpit is treated with this solution, there is no odor of sweat.

Example 3 10 parts of heptanedione zirconate are used in 1000 parts of powder base incorporated. This powder shows good deodorizing properties.

Example 4 Adeps lanae ................. 200 parts of beeswax .................... 25 parts of Oleum olivarum .................. 100 parts of distilled water. ...................... 100 parts alcohol ......................... 100 parts heptanedione zirconate .............. 2.5 parts are worked together.

The cream suppresses unpleasant body odor.

Example 5 500 g of the cadmium complex compound of hexanedione, obtainable by reacting hexanedione and cadmium acetate in a known manner, are in alcoholic Solution incorporated into the liquor of 100 kg of pulp. Sanitary napkins made therefrom show practically complete deodorization even after long periods of wear.

EXAMPLE 6 Textile wadding intended for the manufacture of tampons is before the Pressing with 0.2 0Jo, based on its dry weight, of the Cu complex compound of the Trimethylacetylacetones, obtainable by reacting trimethylacetylacetone with Cu acetate in a conventional manner, impregnated.

Example 7 Diapers are made from cellulose or textile fibers, those during or after production 201, the aluminum complex compound of acetylacetone, obtainable by reacting aluminum chloride with acetylacetone in conventional Way to be added, d. H. detected, printed, filmed, foamed or through Dive.

Example 8 Nonwoven fabric used for the production of shoe insoles is, is available with 201, the copper complex compound of p-amino-benzoylacetone by combining p-amino-benzoylacetone and copper acetate.

Example 9 Fleece is mixed with 20 gIm2 of a solution of the copper complex compound des a-acetoxy-eikandion, obtainable by combining a-acetoxy-eikandion and Copper- acetate, wetted, so that after evaporation of the solvent 0.4 g / m 2 What remains is fleece, which is processed for the production of welding reeds.

Example 10 50 parts of fine-capillary silica gel, 30 parts of coarse-capillary Silica gel, 7.5 parts Adeps lanae, 7.0 parts distilled water, 0.5 part calcium complex compound of 1,3-octanedione, obtainable by reacting calcium carbonate with 1,3-octanedione in water, are made into a powder.
