The present invention relates to the suppression of odors in disposable desiccant products which make use of phosphorus-containing compounds.

At the present time there and used a wide variety of additives used in disposable absorbent products to reduce or suppress unpleasant and bad smells caused by exudates of the human body. It is known that many bad smells associated with the fluids of the body, are caused by microbial decomposition of lipids, particularly triglycerides, and phospholipids, to the level of fatty acids. U.S. patent No. 4356190, for example, describes the use of compounds such as add (ethylenediaminetetraacetic acid) to inhibit the formation of these fatty acids. To suppress the bad smells in the absorbing products were also used other materials, such as zeolites, drinking soda, compounds containing activated carbon and charcoal (see, for example, U.S. patent No. 5306487).

U.S. patent No. 5567231 describes a deodorant containing 5-100 weight % of calcium phosphate at a molar ratio of CA/P, is equal to from 0.8 to 2.0. The specified patent reports that some products, such as filter strips containing calcium phosphate, have shown an increased adsorption capacity of many substances, such as oil-soluble substances, substances, East is committed to smells, viruses and other

The applicant has found that it is possible to reduce or eliminate the allocation of the bad odor associated with microbial decomposition of lipids contained in the fluids of the human body, taking in absorbent products, through the introduction of absorbing these products protivopavodkovoj additive containing at least one water-soluble salt having an anion selected from among,and. Alternatively, such protivoopujoleva additive may contain a water-soluble compound of the formula (ARO3)nin which a represents an element of group I of the periodic table, and n is from 4 to 50.

Thus, the present invention relates to disposable devouring product consisting of a coating permeable to moisture (liquid), and absorbing inner layer, and an absorbing product contains protivogradovoy additive containing at least one water-soluble salt comprising an anion selected from the group consisting of,and.

The present invention also relates to disposable devouring product consisting of a coating permeable to the liquid, will the replacement of the inner layer, moreover, the specified product contains protivogradovoy Supplement containing a water-soluble compound of the formula (ARO3)nin which a represents an element of group I of the periodic table, and n is 4-50.

The present invention also relates to methods of reducing the allocation of bad odors from the disposable absorbent product. According to the proposed methods in absorbing the product is injected protivogradovoy additive containing at least one water-soluble salt containing an anion selected from the group consisting of,andand also containing a water-soluble compound of the formula (ARO3)nin which a represents an element of group I of the periodic table, and n is 4-50.

Mentioned absorbing product may be sanitary (hygienic) cloth strip to panties, leggings or pantalettes, diaper, pad for persons suffering from incontinence of urine or faeces, with a gasket for female genitalia, swab or any other vnutrivlagalischnye device, an insole for shoes or any other similar product intended for the absorption of exudates from the human body, such as menses, urine, faeces and sweat. Preferably absorbing product which is a sanitary napkin or pad for cowards. For the purposes of the present invention such sanitary napkins or pads may be approximately rectangular, oval, or skeletal orechovitsa form. Depending on the nature of the absorbing product of its dimensions may be different. So, for example, sanitary napkins can have a thickness of about 1.4-5 mm, a length of about 3-16 inches (i.e. from 7.62 to 40,64 cm) and a width of the order of from about 2,54 up 12,70 cm). Strip to boxers and pantalettes usually have a thickness of less than about 5.08 cm, length less than 20.32 cm and a width of less than about 7,62 see

From a design standpoint, such absorbent articles typically consist of the following components (viewed from their side facing the body, in the direction of the side facing to the garment): cover, permeable to liquid, moisture-absorbing inner layer and - optional - lining. The coating of the specified products can be made from any moisture and gas permeable material, provided that it fits comfortably to the skin and allows moisture (gases) it is easy to pass to devouring the inner layer, which is water retention. Moreover, the coverage is almost not should or must hold a very small amount of moisture, so that its surface was relatively dry, since it is addressed to the body surface. Know many mothers who lov, suitable for making coatings, and they can all be used. For example, it can be fibrous non woven materials made from polymer filaments or fibers, such as polyethylene, polypropylene, polyester or cellulose. Alternatively, the coating can be made of perforated polymer film. Depending on the selected material, the coating thickness may be from about 0.001 to 0,062 inch (0,0254 mm to 1.57 mm).

Typically, the coating is a solid sheet of material, the width of which is sufficient to form a surface facing the body. Length of coverage can be equal to the length of the absorbing inner layer, or the coating may be longer than the inner layer, forming bulging outward transverse ends. These ends then you can tightly connect with other layers, thereby completely closing an absorbent inner layer.

Absorbent inner layer may consist of tightly adjacent to each other absorbent (absorbent) hydrophilic materials such as cellulose fibers (including wood pulp fibers, regenerated cellulose or cotton fibers, or any other commonly used absorbent materials, including acrylic fibers, fibers of polyvinyl alcohol, peat moss and super-absorbent polymers.

In addition, AB is orbicula item (product) may contain a lining, which substantially or completely impermeable to liquids and forms its outer side the other side of the absorbing product, which is turned into clothing. This lining may contain a film of any thin, flexible, non-permeable for liquids of the human body material, such as polymer film, for example polyethylene, polypropylene or cellophane film. Alternatively, the lining may be made of conventional material, permeable to liquids, but thus treated to be impervious to liquids. For example, it may be impregnated with water-repellent paper or non woven material, or a flexible synthetic foam material such as polyurethane or cross-linked polyethylene. The lining is made from a polymeric film typically has a thickness of approximately 0.001-0.002 inch (0.025 mm - 0,050 mm). For the manufacture of linings you can use a great variety of materials used in this technical field.

Generally speaking, the lining is made from a single sheet of material having a width sufficient to form a surface of the absorbing product, facing to the garment. The lining can be carried around absorbing inner layer, forming a C-shaped structure, and those parts of the pads that are on its longitudinal edge which, pass upwards from the surface of the absorbing product, facing the clothes in the direction of the surface of the same product, facing the body. Preferably the material for the lining should "breathe", i.e. the film is a barrier to liquids, but permeable gases. Materials suitable for this purpose are amongst the microporous film in which microporosity is achieved by pulling the oriented film. Breathable lining can also be created using one or more layers of permeable films, fabrics and combinations thereof, which are superimposed on each other so that they form a tortuous path for the passage of liquids and gases. Alternatively, you can use film and fabric, the surface which prevents the penetration of liquids, but which nevertheless "breathes".

Absorbing the product can be placed in the crotch shorts or pantalettes, attaching side of the item facing the clothing, to the inner surface of the crotch shorts. To secure items in place, you can use ribbon of adhesive tape, which responds to pressure, and to attach these straps to the side of the product facing the clothing. In the framework of the present invention, the term "adhesive that reacts to pressure" refers to any adhesive or retaining means, able to quickly come unstuck and free shipping is to be held item. As examples of such adhesives, reacting to pressure, you can call acrylate adhesive is water-based. Alternatively, you can call rubber adhesives of the "hot melt" or double-sided adhesive tape.

In addition, to protect the adhesive tape on one side can be applied bystrozagruzhaemaya paper strip. The coating, for example, its silicone coating reduces adhesion by covered parties bystrorasshiryayuscheysya strips to the adhesive tape. Such bystrozagruzhaemaya strip can be made of any suitable sheet-like material, which, being deposited in the form of a coating, is attached with sufficient strength to the adhesive (adhesive) tape and left in place until the moment of its use, when it can be easily removed using absorbent products.

The above-mentioned absorbing product may be composed of any other well-known materials, layers, layers, and additives, such as intermediate layers, "frothy" layers, layers with a mesh, aromatic substances, medicines, moisturizing agents, and others (all of them described in detail in this technical field). Moreover, by absorbing the product can be manufactured by stamping decorative patterns in the usual way.

In accordance with the proposed izaberete the receiving and absorbing product contains one or more protivopavodkovyh additives, containing one or more phosphorus containing compounds of the following types: 1) water-soluble salt containing an anion selected from the following group consisting of,andand 2) water-soluble compounds of the formula (ARO3)nin which a represents an element of group I of the periodic table, and n is 4-50. Preferably, these water-soluble salt containing an anion from the group consisting of,andwould be composed of a cation containing an element of group I or ammonium. Even more preferably, if a water-soluble salt containing a cation containing sodium. In this case, particularly preferred tetrasodium pyrophosphate and pentaceraster sodium.

As for the water soluble compounds of the formula (ARO3)nAnd is preferably sodium, and n is preferably from 4 to 50, even more preferably 15-20.

In addition to the above phosphorus-containing compounds protivoshumovye supplements may contain other components, such as ethylenediaminetetraacetic acid (edtc), zeolites, or any other known substances that suppress bad smells.

Protivogradovoy Supplement can is Nedret inside or on the surface of the upper cover, the inner layer of the antireflection coating in the lining of the coating or combinations thereof. Alternatively, if the absorbing product contains additional layers, such as a gear (intermediate) layers, protivogradovoy additive can be embedded on the surface or inside of such intermediate layers. For the purposes of the present invention it is preferable that the antireflection coating product would contain such protivoshumovye agent in the immediate vicinity of the body and from the body, from which there is direct selection of human body exudates.

The physical form in which you enter protivoopujoleva additive, is not essential for carrying out the purposes of the present invention. So, protivogradovoy additive can be introduced in the form of powder or liquid solution. It can also enter in part of one or more adhesive layers used in the absorbing product. An example is U.S. patent No. 4186743 describing the use of microcapsules with deodorant in the adhesive layer of the sanitary napkin.

The number protivopavodkovoj absorbing additive in the product depends on the size and nature of the layer into which it is introduced. As a rule, protivogradovoy additive used in such a quantity to provide a content of about 0.01 to 1.0 grams of phosphate-based connection is placed on the square inch (6.5 cm 2layer, preferably the content of phosphorus-containing compounds per square inch (6.5 cm2layer absorbing products must be in the range of 0.02 to 0.50, note, however, that even smaller amounts of protivopavodkovoj additives reduce the presence of bad smells in absorbing product.

It is believed that the presence protivopavodkovoj supplements can reduce the flow of bad smells due to the intervention of the additive decomposition of lipids bacteria into fatty acids in the exudates of the human body. In addition, protivoopujoleva additive has a basic pH and is therefore capable of neutralizing the formed fatty acids.

An advantageous feature of the present invention is the fact that phosphorus-containing compounds contained in protivopavodkovoj additive is safe for humans. Moreover, they are relatively less harmful to the environment than many other compounds. And finally, they are cheaper than, for example, etc.

The invention is illustrated in the following example:
