The technical field to which the invention relates.

The present invention relates to absorbent articles intended to absorb body fluids, including the control system of the smell, which is activated only when needed by the moisture contained in the body fluids.

The level of technology

Absorbent articles for personal hygiene are known from the prior art. Typical examples include sanitary napkins, pads, tampons, interlabial products, gaskets for adults with incontinence and baby diapers. These products are traditionally used to absorb and retain body fluids and other exudates, which are secreted by the human body. Typically, these exudates are seen as smelly and unpleasant. Therefore, the developed methods and materials to control and reduce the stench in absorbent products. Fragrant substances were widely used for this purpose in absorbent products, as well as ingredients such as silica or zeolites, are able to capture some of the molecules, creating a stench.

Other materials that are useful to improve the perception of odor absorbent products are compounds that can have a pleasant smell themselves, and may not have it but the pic is service to improve the perception of the odor of a composition or product, with which they are associated. Such materials can act, for example, by modifying how certain nasal receptors perceive the stench, or by exposure to malodorous substance by a chemical reaction or complexation, or absorption/adsorption, for example.

In this application, the term "material, managing smell" includes any material, such as all of the above materials can improve the perception of the odor absorbent products before, during and/or after it is applied.

A large class of ingredients that it is desirable to use as material components, control odor, for use in absorbent products, is a class of organic compounds. In the context of this application under "organic compounds" refers to an organic molecule that, when introduced into an absorbent article capable of ensuring the improvement of the perception of the smell of the product. Unlike inorganic components such as silica, carbon black and zeolites that are physically trap odors, organic compounds that are active in the perception of odors user absorbent products are directly active in the modification of odor absorbent product at any stage of the application, for example by providing fragrance by direct or indirect reaction to the foul-smelling substances ("indirectly" is meant, for example, if the organic compound has antimicrobial effect against bacteria, generating malodorous substances) or by modifying the perception of odors nasal receptors.

Most of the organic compounds that can be used in materials, control odors, are volatile and tend to evaporate to some extent, so that their number in the commercial absorbent product difficult to manage. After the manufacture of absorbent products, organic compounds begin to evaporate and, depending on time and conditions of storage before use, a larger or a smaller part of the material, control odor, will be evaporated and therefore no longer effective.

Hermetic closing of products solves the problem only partially, because of the tight closing, consistent with the cost of such absorbent articles, typically is not perfect and in any case a large number of volatile materials, control odors, as is lost during use of the absorbent product when heated body.

Materials, control odors, instead, the most necessary at the time when the absorbent isdel the e load body fluids, i.e. in the final period of its application and during replacement.

Most vysokoletuchie materials, control odors, have a tendency to evaporation during the first minutes of applying the product, ensuring, for example, pleasant sensations during the process of wearing the product, but do not have other benefits, if later, the product load stinking body fluids.

To save volatile compounds over a longer time successful approach is the inclusion of volatile organic compounds in the inclusion complexes of cyclodextrins (alpha cyclodextrins and/or beta cyclodextrins are examples of cyclodextrins that can be used in this application). Examples of such complexes are described in the patent US 5580851 and in WO 2008/104960, but the present invention can be used any inclusion complex of cyclodextrin with an organic compound. Such complexes are very effective as they remain active control odor and release it if they moisten body fluids.

The inclusion complexes of cyclodextrin molecules are, in General, in the form of fine material, which, in General, produced by spray drying of a solution containing cyclodextrin and organic compounds. Believe that cyclodextrins form the idea is to enable with organic compounds and spray drying they prevent the evaporation of organic compounds through chemical bonds, educated linked in a complex compound. If the material is wetted, such ties weaken, and the organic compound is slowly released. Materials in the form of particles sometimes difficult to handle in certain industrial installations due to safety regulations, which require very careful handling of fine powders, in particular organic compounds, as in the case of inclusion complexes of beta-cyclodextrin.

Additionally, the natural humidity of the air and the moisture absorbent products can cause the release of bound in complex organic compounds before it is desired.

Therefore desired is to provide articles containing such inclusion complexes in a form that can be easily incorporated in such products and protected from moisture.

The invention

The present invention relates to an absorbent product containing material, managing smell, when it is specified material, managing odor, contains at least one inclusion complex of cyclodextrin with an organic molecule, which is dispersed in the matrix containing polysiloxane oil.

Detailed description of the invention

The term "absorbent article" is used in this application in a very broad sense, including any product, methods for the Noah to the intake and/or absorption and/or content and/or retaining liquids and/or exudates, in particular body fluids/exudates of the body. Illustrative absorbent products in the context of the present invention are disposable absorbent articles. The term "disposable" is used in this application to describe products that are not designed for washing or other recovery or reuse as a product (i.e., they are intended for disposal after a single use and, preferably to be used for other purposes, turning into compost, or other application method is harmless to the environment). Typical disposable absorbent articles in accordance with the present invention are diapers, surgical dressings and bandages on the wound and gaskets for perspiratio, gaskets for patients with incontinence, as well as absorbent articles for feminine hygiene products such as sanitary napkins, pads, tampons, interlabial devices, etc. Absorbent articles suitable for use in the present invention include any structure, from one absorbent layer to more complex multilayer structures. Some absorbent articles include permeable to liquids upper fabric, bottom fabric, which may be impermeable to liquids and/or may be pronice the output for water vapor and/or gas, and the absorbent element, placed between them, which is often called "primary absorbent element" or simply "basis.

The term "application"as used in this application refers to the period of time that begins when the absorbent product is actually brought into contact with the body of the user.

Under the "fluid body" in this application is meant any liquid that produces the human body, including but not limited to the above, sweating, urine, menstrual flow, vaginal secretions and so on

The present invention relates to an absorbent product containing material, managing smell, where specified material, managing smell contains at least one inclusion complex of cyclodextrin with an organic molecule, dispersed in the matrix containing polysiloxane oil.

The absorbent product in accordance with the present invention can be any kind of absorbent articles for personal hygiene, known from the prior art as described above, in particular an absorbent product for feminine hygiene, and typically contains permeable to liquid, the upper fabric, bottom fabric, and an absorbent element between them. Each of these elements, as well as any other optional layer is present in an absorption is the product has a side facing the body or the side facing the user, and the side facing to the garment, or the external front side corresponding to the side facing respectively to the body and the clothes of a user during use of the product. As is well known in the prior art, may also be present other additional layers of material, for example, the secondary top sheet and/or cumulative layers that may be present between the top sheet and the absorbent element, and in General used to improve the distribution and prevent the return of body fluids on the top of the canvas.

As is known from the prior art, the top cloth can be made from a wide range of materials, including, but not limited to the above, woven and nonwoven materials; polymeric materials, such as molded thermoplastic film with holes, plastic film with holes and hydroporinae thermoplastic films; porous foams; foam of low density; thermoplastic film of low density and thermoplastic mesh. The top canvas is typically a special individual element in an absorbent product in accordance with the present invention, containing one or more layers;

however, in the absorbent product in accordance with this izopet the top of the canvas involve as appropriate layer or element, which, when used in direct contact with the user's body, for example, the top sheet can be the top layer of the absorbent element being essentially a part of the absorbent element.

The absorbent element may be any absorbent element, which, in General, is compressible, pliable, not irritating the skin of the user, and is capable of absorbing and retaining liquids such as urine and other certain body exudates. The absorbent element can be manufactured in a wide range of sizes and shapes (e.g., rectangular, hourglass-shaped, T-shaped, asymmetric, etc) and from a wide variety of absorbent liquid materials that are traditionally used in disposable clothing without zippers or other absorbent articles such as comminuted wood pulp, which in General are called "airfelt". Examples of other acceptable absorbent materials include the packing of creped cellulose wadding; meltblown-polymers, including coform; chemically thickened, modified or cross crosslinked cellulosic fibers; tissue, including tissue wraps and tissue laminates; absorbent foams; absorbent sponges; super-absorbent polymers; absorbent, geleobrazuyuschie materials; or any equivalent is a material or combination of materials. The configuration and construction of the absorbent element can vary (for example, the absorbent element may have a different zone thickness, a hydrophilic gradient, superabsorbent gradient, or accumulation area with a lower average density and lower average primary mass; or can include one or more layers or structures). Additionally, the size and absorbent capacity of the absorbent element may also vary in order to accommodate users ranging from children to adults. However, the total absorbent capacity of the absorbent element must be compatible with the structural load and the target destination disposable products.

The absorbent element can include other optional components. One such optional component is the main wrapper, i.e. the material, which is typically, but not always, is a non-woven material which partially or as a whole covers the absorbent element. Acceptable materials of the main wrapper include, but are not limited to the above, cellulose, hydrophobically modified non-woven fabric, perforated film, and combinations thereof.

The bottom sheet can be impervious to liquids (e.g., urine or menstrual blood) and may be made of thin plastic the film. In an alternative implementation the bottom of the canvas allows the removal of vapors from disposable absorbent articles; for example, as the lower blade can be used microporous plastic film or non-woven fabric. One suitable material for the bottom cloth absorbent articles in accordance with the present invention can be liquid impermeable thermoplastic film having a thickness of from about 0.012 mm to about 0,051 mm, for example, including polyethylene or polypropylene. The lower canvas may be a basic weight of about 5 g/m to about 35 g/m2. However, it should be noted that other flexible liquid impervious materials may be used in alternative as the bottom of the canvas. In this application, "flexible" refers to materials that are pliable and can easily take the General shape and contours of the user's body. The bottom fabric is typically located adjacent to the outer face side of the primary absorbent member and may be attached thereto by any reasonable means for attaching known in the art. For example, the bottom sheet can be attached to the primary absorbent element using a uniform continuous layer of adhesive, figured layer of adhesive or n is boron separate lines, spirals, or spots of adhesive.

If the absorbent product in accordance with the present invention is a product for feminine hygiene, for example, sanitary pad, daily gasket or product for patients with mild incontinence, it is typically used when it is glued to part of the crotch of underwear using acceptable means of joining, typically, a layer of self-adhesive adhesive, which is usually referred to as the adhesive to attach to the cowards, provided on the side facing to the garment, the bottom of the canvas. Before use, the adhesive for attachment to the cowards protect with a layer of release, which is attached with the potential for subsequent removal, which removes the user, opening the adhesive, if the product is subject to attachment to the undergarment. As is known from the prior art, the release layer can be for example a canvas of siliconized paper or a cloth wrapper, typically made of a polymeric film, which may also provide a disposable single wrapper for a product.

Absorbent articles in accordance with the present invention contain material that controls odor, where specified material, managing odor, contains at least one inclusion complex of cyclodextrin with an organic compound, the dispersion is new in the matrix, containing polysiloxane oil.

Organic compounds

As mentioned in the section "prior art", and a high grade ingredients, which is preferably used as material components, control odor, for use in absorbent products are organic compounds. In particular, organic compounds that are active in the perception of odors user absorbent products.

Such compounds include all fragrant ingredients (as they are known to experts in the field of perfumes and also all such organic compounds that are not considered traditionally as "odoriferous substances", but which are directly active in the modification of odor absorbent product at any stage of the application, for example, by providing fragrance by direct or indirect reaction to the foul-smelling substances ("indirectly" is meant, for example, if the organic compound has antimicrobial effect against bacteria, generating malodorous substances) or by modifying the perception of odors nasal receptors. Lists of organic compounds suitable for use in this application, particularly non-traditional fragrances are listed in patent applications EP 1886698, EP 1842564 and WO 2008/104960, all p is given The Procter & Gamble Company.

In terms of reactive compounds that are very effective are those that react with ammonia. Ammonia, in fact, is one of the components of the stench of body fluids. For example, ammonia is present in large quantities in the products used to absorb urine, because urine is decomposed. Ammonia and its derivatives can react with aldehydes with the formation of Eminov (in accordance with the so-called reaction of Schiff bases).

This reaction catalyze enzymes and/or slightly acidic pH values from 4 to 5. Requirements for moderation acidity needed to allow protonation of the hydroxyl intermediate connections, to allow the removal of water.

Many aldehydes capable of imine reactions are unpleasant and/or too intense smell, which can disturb the human nose and/or they are very volatile and thus not stable product. Therefore, in most implementations use the selected aldehydes to control unpleasant odors. Examples of acceptable aldehydes to control unpleasant odours are aldehydes, capable of reaction with amino compounds in accordance with the reaction of Schiff bases and have no unpleasant smell. PR is integral aldehydes include exilarchy aldehyde, alpha imilarity aldehyde, p-anisaldehyde, 4-formyl-2-methoxyphenyl 2-methylpropanoate, benzaldehyde, cinnamic aldehyde, semenovii aldehyde, decanal, p-t-butyl-alpha-methyldihydromorphine aldehyde, 4-hydroxy-3-otoxicity aldehyde, 2-phenyl-3-(2-furyl)prop-2-enal, vanilla isobutyrate, ethylvanillin acetate, unilineatus, cyclomancy aldehyde, heptanal, laureldale, nonanal, octanal, phenylacetaldehyde, peripapillary, vanillin, salicylic aldehyde, citral, 2,4-dihydroxy-3-methylbenzaldehyde, 2-hydroxy-4-methylbenzaldehyde, 5-methylsalicylate aldehydes, 4-nitrobenzaldehyde o-nitrobenzaldehyde, 5-ethyl-2-thiophenecarbaldehyde, 5-methyl-2-thiophenecarboxaldehyde, 2-thiophenecarbaldehyde, asianlineid, 5-(hydroxymethyl)-2-furaldehyde, 2-benzofurazanyl, 2,3,4-trimethoxybenzaldehyde, protocatechualdehyde, heliotropin, 4-ethoxy-3-methoxybenzaldehyde, 3,4,5-trimethoxybenzaldehyde, 3-hydroxybenzaldehyde, o-methoxycinnamaldehyde, 3,5-dimethoxy-4-hydroxycinnamic, 2,8-dithianon-4-3n-4-carboxaldehyde, aldehyde sorbic acid, 2,4-heptadienal, 2,4-decadienal, 2,4-nonadienal, 2,4-nonadienal, (e,E)-,2,4-octadien-1-al, 2,4-octadienal, 2,4-dodecadienal, 2,4-undecadienal, 2,4-tridecoder-1-al, 2-TRANS-4-CIS-7-CIS-tradictional, piperidinophenyl, 2-methyl-3-(2-furyl)acrolein, 2,4-pentadienyl, 2-furfari debuteerisid, 3-(2-furyl)acrolein, an aldehyde grape acid, ethandiol and mixtures thereof.

In another implementation, the aldehydes can be selected from mexikoring aldehyde, 4-hydroxy-3-methoxycinnamaldehyde, decanal and mixtures thereof.

Other organic compounds that are acceptable in this application are compounds acting on the nasal receptors. The materials listed in this application, inhibit nasal receptors in the application entitled "blocking the nose. When using such materials can significantly reduce the ability of the nose to detect odors. Blockage of the nose perhaps due to the volatile nature of the selected material which evaporates from the absorbent product and then inhaled by the nose individuals, in General, in a narrow range of products, for example in the range of about from 0 to 10 meters products (although this should in no way be intended to limit the scope of the present invention) by a normal breath is. Blocking the nasal receptors is, of course, only temporary. Acceptable blocking the nose materials include menthol, methylacetate, (5R)-2-methyl-5-prop-1-EN-2-icicles-2-EN-1-it, 3-methyl-4-(2,6,6-trimethyl-2-cyclohexen-1-yl)-3-butene-2-it, methyldihydromorphine, hexyl-2-methyl butyrate, 4-(2,6,6-trimethylcyclohex-1-EN-1-yl)but-3-EN-2-it, 4-(2,6,6-trimethyl-1-cyclohexen-1-yl)-3-butene-2-it, 3-butene-2-it,4-(2,6,6-trimethyl-2-cyclohexen-1-yl)-, (E)-, Mantellate, isomertieite, isopentylamine, sometimesesoteric, isoantibodies, camphor, p-Menten. The materials also include their isomeric forms, diastereoisomers and enantiomers. Mainly, in General, the above materials have only a very weak inherent smell, but show a high degree of blocking of the nasal receptors.

All the organic compounds listed above can be included in the material, managing smell, either individually or, more often, in the form of their mixtures.

The inclusion complex of cyclodextrin

As used in this application, the term "cyclodextrin" includes any of the known teledensities, for example, substituted and unsubstituted cyclodextrins containing from about six to about twelve links of glucose, such as alpha-cyclodextrin, beta-cyclodextrin, gamma-cyclodextrin and/or their derivatives and/or mixtures thereof. For example, the present invention can be used cyclodextrins selected from the group consisting of beta-cyclodextrin, alpha-cyclodextrin, hydroxypropyl alpha-cyclodextrin, hydroxypropyl beta-cyclodextrin, methylated alpha-cyclodextrin, methylated-beta-cyclodextrin and mixtures thereof.

Particle cyclodextrin and the inclusion complexes of cyclodextrin organic compounds can be formed by various the different ways which are well known in the art. An early reference is the European patent EP 392608 B1 from The Procter & Gamble Company, describing the inclusion complexes of cyclodextrin organic compounds and their use in disposable absorbent products.

For example, the solvent (e.g., water or an organic solvent suitable for complexing organic compounds), the unloaded particles cyclodextrin and organic compound, which is necessary to bind to the complex can be placed in the container and then mixed for a period of time to ensure the loading of organic molecules in the "cavity" cyclodextrins molecules. The mixture may or may not be additionally processed; for example, processed through a colloid mill and/or homogenizer. The solvent then being removed from the resulting mixture or suspension to obtain particles of a complex of cyclodextrin, for example by spray drying. Various manufacturing techniques can, however, give different characteristics of the particles/complexes, which may or may not be desirable in absorbent products, depending on the particular application and conditions. In some implementations, the particles of the inclusion complexes of cyclodextrin have a low level of moisture lane is on their inclusion in the polysiloxane carrier, typically less than about 20% by weight of the particles, or less than about 10% by weight of the particles, or less than about 6% by weight of the particles. The spray drying of the suspension of the inclusion complexes of cyclodextrin and organic compounds is one of the manufacturing techniques capable of obtaining particles of cyclodextrin and cyclodextrin complexes with the above levels of moisture. The cyclodextrin complexes can also be obtained by means of known technologies and extrusion process (mixing), but the resulting material is, in General, contain higher levels of moisture and have less complexing efficiency. WO 2008/104960 from The Procter & Gamble Company provides a detailed overview of the most appropriate technologies for inclusion complexes of cyclodextrin.

Polysiloxane oil.

In accordance with the present invention, the inclusion complex of cyclodextrin dispersed in the matrix containing polysiloxane oil. In some cases, the inclusion complex of cyclodextrin dispersed in the matrix, containing more than 50% or more than 70%, or more than 90% wt. polysiloxane oil (with the exception of the inclusion complex of cyclodextrin) or dispersed in a matrix consisting of polysiloxane oil. All implementations polysiloxane m the words may be a polydimethylsiloxane (PDMS) or polysiloxane polymer, grafted on a polyester (typically, polietilenoksidnoy and/or polypropyleneoxide) circuit, such, as well as having the name "siliconvalley copolymers or poly(oksietilenom, oxypropylene) methylpolysiloxanes copolymer". Such materials are commercially available from Dow Corning and one of the acceptable examples is DC 190. The presence of polyether chains grafted on to a polysiloxane skeleton may increase the hydrophilicity of the main polymer without affecting the release of organic material from the inclusion complex, thus more hydrophilic matrix allows the best flow of fluid and the rate of accumulation in absorbent products even in the presence of relatively large quantities of material, control odor.

The dispersion of the polysiloxane oil complex of cyclodextrin is in the form of a liquid with low viscosity, which can easily handle during the manufacture of absorbent products and which can be applied to the absorbent article at any stage of the manufacturing process.

An additional advantage of using the dispersion of polysiloxane oil complex of cyclodextrin is that the material can be easily applied figural image on the desired surface, as will be described below in the description of the sample application.

In General, the mass with the compared matrix, containing polysiloxane oil and inclusion complex of cyclodextrin is from 10:1 to 1:2. In some cases, it may range from 5:1 to 1:1. In other cases, it may vary from 2:1 to 1:1. A large amount of inclusion complex of cyclodextrin can give to the material too much pastorates to make it easy to handle, while a small number may require too many matrix to deliver the proper amount of inclusion complex of cyclodextrin in an absorbent product.

As noted above, most of the organic compounds that can be used in materials, control odors, are volatile and tend to evaporate to some extent so that their number in the commercial absorbent product difficult to manage. To save volatile compounds one of the successful approaches is the inclusion of volatile organic compounds in the inclusion complexes of cyclodextrins. Such complexes release associated in the complex connection when activated by contact with moisture, such as may be contained in body fluids. Having no desire to be bound by theory, believe that the presence of water can weaken the chemical bond between the cyclodextrin and the organic compound of pedemontana hydrogen bonds within it. In some cases, therefore, the inclusion complex of cyclodextrin must be protected from moisture which may be present in the air or may contact the absorbent product during its storage. The present invention provides a solution to protect from moisture complex of cyclodextrin organic compounds, at the same time, allowing easy and complete release if necessary.

As it has been unexpectedly discovered that a particular selection polysiloxane oil provides a significant advantage because the more hydrophobic matrices (such as mineral oil or petrolatum) is used, the less chance the body fluids to contact the inclusion complex of cyclodextrin, while the more hydrophilic matrices are used (such as PEG or glycerol), such matrices can cause the release of bound in the complex connection earlier than is desirable. Matrix-based polysiloxane oil effectively protects the complex from moisture and at the same time allows a quick release if necessary.

The advantages provided by the present invention, will be present for any organic compounds, as well as all organic compounds that are acceptable in this application have a certain volatility, however, the benefits will be more pronounced is passed for organic compounds, with higher volatility, so that the present invention is particularly appropriate when the organic compound selected from organic compounds having at least medium to high volatility.

In the present invention, the volatile organic compounds was measured by their index Kovacs. Index Kovacs is a standard measure that is produced in the perfume industry for aromatic raw materials and which, in this case, has been applied to all organic compounds in accordance with the present invention.

Index Kovacs organic compounds is determined by the selective retention of organic compounds on chromatographic columns. Index values Kovacs in this application get chromatographic column DB-5 (or equivalent), 30 m, 0.25 mm, 1.00 micron, which operates under the following conditions: 50-300°C, 4°C/min, to 12.0 lb/square inch, constant flow; DB-5 column, for example, available from Agilent Technologies Inc. (formerly J&W Scientific), equivalent column can be easily determined by a person skilled in the technical field of using public equivalence tables. The value of the index Kovacs for organic compounds is determined by its polarity, molecular weight, vapor pressure, boiling point and the stationary property is the basics, and considered as a good measure of its volatility.

For the purposes of the present invention consider organic compounds with medium to high volatility, where such compounds have the index Kovacs 500-2000.

Absorbent articles, which are provided with a material, managing odour in this application can be any type of absorbent articles for personal hygiene, known from the prior art. Material, managing smell, in accordance with the present invention, may be present in any part of the absorbent product. In some implementations, the system control odor can be applied on the user side of the upper blade, or on the side of the garment top of the canvas, or inside the top of the canvas, or on the user side of the absorbent element, or on the side of the garment, the absorbent element, or within the absorbent element, or on the user side of the lower blade, or (in the case of the presence of the secondary top sheet) on the user side of the secondary of the upper blade, or on the side of service secondary upper cloth, or within upper secondary paintings, or (in the case of the presence of cumulative layer) on the side of the user's cumulative layer, or on the side service cumulative layer, or within the cumulative layer, or on any side of any what about the other component of the absorbent product, if it is present, for example, the core wrap, plastic foam or non-woven layers, the secondary bottom of the canvas, or their mixture. Size of the host material, control odor, usually found in liquid communication with the space in which the fluid organism in the product.

In those implementations where the material that controls odor, put on the user side or the side of the garment, the absorbent element, or within the same absorbent element, or on the surface of another layer, forming the product, the surface is in direct contact with the surface facing to the garment, or the surface facing the body, the absorbent element, material, managing smell, may be more effective, since this configuration allows a closer and more continuous contact with body fluids.

As mentioned, the material that controls odor, can be ingested or applied on any of the layers of absorbent products. If it is applied to the surface layer, it can be evenly sprayed, but in General, it is preferable application of the material, control odor, in the form of patterns, such as spirals, snakes, strips, bars or any other patterned coating, known from the prior art. For example, the material, manage the s smell, can be applied using conventional equipment for applying adhesives, such as an applicator with a hole that can be applied to patterns-stripes, or pneumatic applicators for application in the form of patterns (for example, spraying, spirals, snakes, fibers. Omega®, Signature®, and the like), because it allows you to position the material, managing smell, in a way that does not affect the accumulation of fluid (i.e. the product for feminine hygiene material is not deposited in accordance with the vaginal opening) and in any case, the pattern having a big empty space allows the penetration of fluids on hand. Also patterned deposition are useful because they allow precise application in such a way that facilitates the avoidance of contact with the glue connecting the various layers of the product, and the operation of which may have a negative impact contact with Policia xanavi oil.

Figure 1 shows an absorbent product in accordance with the present invention. Fig.1b is a section of the same product along the line specified by using (i) in figure 1.
