The technical field to which the invention relates.

The composition is in the form of a lotion applied on the basis that constitutes, or forms, or used for the manufacture of absorbent products such as diapers, training pants, a product for adults with incontinence or feminine hygiene product that can be used to reduce the adherence of feces or menstrual discharge to human skin. The composition is in the form of a lotion applied on a basis which is, or forms, or used for the manufacture of absorbent products, such that there is a negative impact on the manufacturing process and gives the basis of the desired properties hold liquid. The composition in the form of lotion can also be preferably applied to the substrate, which is used as a napkin, or in it.

The level of technology

Known disposable absorbent products such as diapers and sanitary napkins having upper canvas containing lotion to provide beneficial effects to the skin of the user. Recently studied the delivery lotions to hygienic napkins and diapers, providing additional beneficial effects for the skin, for example, by adding herbal ingredients or pharmaceutical ingredients for lotions. As you know, lotions is hypoxia types provide various beneficial effects for the skin, such as prevention or treatment of diaper rash. These lotions can be applied on top of the canvas absorbent products, and can be transferred to the skin of the user during use. Adding lotion to the top cloth absorbent products also known as providing such beneficial effects as easier cleaning of the skin from faeces and menstrual blood. For example, US 5,968,025, issued to Roe et al., WO 97/05908, WO 97/05909 and US 2006/140924 describe absorbent articles having soaked in the lotion of the upper blade to reduce sticking of feces to the skin, the composition in the form of lotion are mainly hydrophobic. In the US 3,489,148, issued to Duncan et al., describes the diaper containing hydrophobic and oleophobic upper surface, in which the upper part of the canvas is covered with a continuous film of fat-containing material.

The lack of diapers described in the link Duncan et al., and other nappies treated hydrophobic lotions is the fact that hydrophobic and oleophobic upper blade slowly transfer the urine into the lower absorbent inner layers. Hydrophobic composition in the form of lotion also tend to leave undesirable feeling fat or stickiness on the skin. Hydrophilic compositions in the form of a lotion overcome many of these shortcomings. WO 05/035013, WO 00/64500, WO 00/64501, patent application U.S. 002-120241 and U.S. patent 6,756,520 describe absorbent articles with hydrophilic compositions in the form of a lotion for various applications, for example, increasing moisture or lubrication, to reduce mechanical damage to the skin, to improve the health of the skin, to enhance the barrier function of the skin and for the prevention and relief of skin irritations. EP 1992366 A1 and EP 1992367 A1 describe absorbent articles with hydrophilic lotion that is transferred to the skin and limits the adherence of feces or menstrual blood to the skin (properties anti-stickiness). However, applicants found that some of these hydrophilic compositions in the form of a lotion, limiting the adherence of feces or menstrual blood to the skin can have problems with processing, in particular, in high-speed processes. Applicants also found that some of these hydrophilic lotions are not always effectively delivered to the skin, thus, decreases their effectiveness. Applicants found that the treatment of the hydrophilic compositions known from the prior art, in the liquid state under conditions of high temperature process, such compositions can remain in a liquid state after application to the Foundation for a significant period of time, thus adversely affecting the manufacturing process. In addition to processing problems, the longer the composition in the form of lotion remains in the liquid state, the more pronounced her tendency to m who graces the inside of the product, and the less is available for transfer to the skin or remains between the skin and the surface, in contact with skin absorbent products that are used. Known issues processing associated with some hydrophilic compositions in the form of a lotion. US 6,515,029 describes the processing tools to reduce the time required for hardening compositions in the form of a lotion when applied to an absorbent product. However, applicants found that the proposed solutions are not satisfactory for hydrophilic compositions in the form of lotions, intended to reduce sticking of faeces and menstrual blood to the skin of the user; the applicants found that the proposed solutions known from the prior art, can degrade the properties of these specific hydrophilic compositions in the form of lotions.

Thus, there is still a need for absorbent articles for applying to the skin or worn by the user, such as wipes, diapers, sanitary napkins and the like, containing a base, for example, facing the body surface of the absorbent articles containing hydrophilic lotion that is easy to handle, even at high speed, and which is effectively transferred to the skin to effectively reduce the adherence of feces or menstrual discharge to the her.

Therefore, an object of the present invention is to provide the framework that constitutes, or forms, or used for the manufacture of absorbent products or wipes containing transmissible composition in the form of a lotion which is easily handled, even at high speed, when the effective reduction of the adhesion of faeces or menstrual blood to the skin.

For example, the applicator cushioning type may be part of the strip applicator having a surface coated with a composition in the form of a lotion for distribution, and the vertical part of the arm.

The base useful in the present invention

The term "basis" as used in this application, in General, refers to a material that constitutes, or forms, or is used to make the upper of canvas and/or cuffs for the legs and/or barrier cuffs and/or the side flaps and/or the side panels and/or wings absorbent products. The Foundation may also be a material suitable for manufacture or acceptable as a napkin, or in it.

Suitable materials include woven and nonwoven materials (typically materials fabrics, including woven or non-woven cloth made of fibers); polymeric materials fabric, such as formed with a hole) thermoplastic film (with a hole) plastic is the new film hydroformylating thermoplastic films, porous foams, reticulated foams, reticulated thermoplastic films and thermoplastic scrims; paper tissue or combinations thereof.

Other bases may include materials that are acceptable in order to be part of a strip applicator cushioning type, such as a flexible elastic polymer foam material that does not react with the composition in the form of lotion for distribution applicator. Illustrative elastic material includes urethane foam, polyethylene foam, etc.

"Nonwoven" as used in this application refers to a finished canvas designed or randomly oriented fibers bonded by friction and/or cohesion and/or adhesion, excluding paper and products which are woven, knitted, quilted, sewn, including the binding threads or fibers, or felted by wet milling, with additional flashing or without it.

Preferred bases in this application may be or may contain material non-woven cloth, but such non-woven fabric can be manufactured using a wide variety of known methods. Non-limiting examples of methods include spunbond method, itching, wet process, the process air, melting, piercing needle, mechanical pneumoslide the group thermomechanical pneumovagina, gidropnevmosistemy, calendering and their combination.

Acceptable bases include curtain material (for example, woven or non-woven fabric containing natural fibers or synthetic fibers, or combinations thereof. Examples of natural fibers can include natural cellulose fibers, such as fibers made of hard wood, soft wood, or other non-woody plants. Natural fibers may include cellulose, starch, and combinations thereof. Synthetic fibers can be any material, such as, but not limited to the above selected from the group consisting of polyesters (e.g. polyethylene terephthalate), polyolefins, polypropylene, polyethylene, polyesters, polyamides, polyetherimides, polyvinyl alcohols of polyhydroxyalkanoates, polysaccharides, and combinations thereof. Additionally, the synthetic fiber may be a single component (i.e., one synthetic material or a mixture comprising all the fiber), the two components (i.e., the fiber is divided into sections, the sections include two or more different synthetic materials or mixtures thereof and may include jointly extruded fiber and the core and covering fibers) and their combinations. Bicomponent fibers can be used as a component fiber material is and paintings, and/or they may be present to act as binders for other fibers present in the material fabric. Any or all of the synthetic fibers may be treated before, during or after manufacture to change any desired fiber properties.

The base useful in the present invention may be or may contain layered webs of two or more nonwoven webs. Layered canvas can contain a layer (layers) of spunbond (S)and/or layer (s) of meltblown (M), and/or carded layer (s) (S). Acceptable layered canvases include, but are not limited to the above, SS, SSS, SMS or SMMS. The base useful in the present invention may have a bulk of from about 5 to 100 g/m2. If the basis is, or forms, or used to manufacture top of the canvas, cuffs and/or barrier cuffs and/or the side flaps and/or wings absorbent products, it may be, for example, the bulk of from about 5 to 100 g/m2or from about 10 to 40 g/m2or from about 10 to 30 g/m2. If used as a napkin or in her, she may, for example, to have the bulk of from about 15 to 100 g/m2or from about 30 to 95 g/m2or from about 40 to 85 g/m2or from about 45 to 5 g/m

The base useful in the present invention, may comprise, or may form, or may be used to make the upper cloth absorbent products. The top fabric is oriented to and in contact with the user's body, allowing the rapid penetration of the secretions of the body through it, not allowing the fluid to flow back through the top fabric to the skin of the user. The top fabric is preferably made of a hydrophobic material to isolate the skin of the user from liquids which have passed through the top sheet and contained in the absorbent inner layer (i.e., to prevent re-hydration).

The Foundation, which is, or forms, or used to manufacture top cloth absorbent products, can alternatively or additionally be provided with a hole, i.e. the upper surface has a number of holes hole size of at least about 0.2 mm2. The upper surface has preferably an open area of at least approximately 10%, the open area is the sum of all the holes. The open area can be determined by the procedure described in WO 95/05139.

The basis may be, or may form, or may be used for the manufacture of the upper blade having one or more apertures. Typically, about what verste are large enough, to allow peculiar or menstrual discharge to take place in the empty space below the top of the canvas, also called anal or vaginal cuff cuff. For example, the patent application U.S. No. 2006/0058766 And filed September 13, 2005, describes an absorbent article in which the top cloth is provided with at least one aperture adapted to receive fecal material. These top panels can be made of or can contain a liquid impermeable material, and thus, the base may be liquid impermeable material.

Compositions in the form of a lotion, useful in the present invention

Compositions in the form of a lotion, useful in the present invention, reduces the adherence of feces or menstrual discharge to human skin. In one implementation, they can improve the ease of removal of faeces or menstrual discharge after using absorbent products containing specified composition in the form of lotion and removal by the user. Without being bound by theory, believe that the composition is in the form of a lotion can reduce the force of adhesion between pollution or exudates and the surface of the skin, since the strength of adhesion can be smaller than the force of cohesion in the dirt or exudates, thus allowing dirt or exsd there to separate from the skin surface after application of shear forces (for example, created by wiping).

When applied on a basis which is, or forms, or used for the manufacture of absorbent products, compositions in the form of a lotion can be transferred to the skin by normal contact, movement of the user (thus creating friction), and/or under the influence of heat of a body.

When applied on a basis, which is used in, or as a napkin, or when applied to the basis consisting of the part of the strip applicator cushioning type composition in the form of a lotion can be easily transferred from the Foundation to the skin by applying a relatively small force to the base (for example, by wiping the surface such as the skin of the perianal region, napkin, or wiping perianal region surface applied product, i.e. the cushioning part of the applicator gasket type).

The transfer or migration of the compositions in the form of a lotion on the skin for the introduction and/or coating compositions in the form of a lotion, causing a safe and effective amount of the compositions in the form of a lotion. Safe and effective amount of the composition in the form of a lotion, will be transferred or migrated to the body will depend on such factors as the type of composition in the form of a lotion, which is applied to the portion facing the body surface of the substrate, where the composition is applied in VI is e lotion and the type of absorbent products which are used for the introduction of the composition in the form of a lotion. In one implementation, the effective amount is the amount, contributing to decreased adherence of feces or menstrual discharge to the human skin of the user who wears the absorbent product, compared to the absorbing product without composition in the form of a lotion. The effective amount in accordance with the present invention may range from about 0.0015 mg/cm2(0.01 mg/inch2) to approximately 100,5 mg/cm2(100 mg/inch2), preferably from about 0.003 mg/cm2(0.02 mg/inch2) to approximately 12,4 mg/cm2(80 mg/inch2), more preferably from about 0.02 mg/cm2(0.15 mg/inch2) to approximately of 7.75 mg/cm2(50 mg/inch2), composition in the form of lotion on absorbent product. Typically, a safe and effective amount of the compositions in the form of lotion in accordance with the present invention is applied on the absorbent article in such a way that, at least from approximately 0,00015 mg/cm2(0.001 mg/inch2) to approximately 15.5 mg/cm2(100 mg/inch2), preferably from about 0,0006 mg/cm2(0.004 mg/inch2) to approximately 11 mg/cm2(72 mg/inch2), more preferably from is roughly 0.005 mg/cm 2(0.03 mg/inch2) to about 6.2 mg/cm2(40 mg/inch2), composition in the form of a lotion is transferred to the body during a single use absorbent products, which typically is approximately three-hour period. To determine the number of compositions in the form of a lotion, described in this application, which is transferred onto the user's body during use of the absorbent articles containing composition in the form of a lotion, can be used by any acceptable method. Examples of methods of calculating amounts of transfer compositions in the form of a lotion include gas chromatography and other quantitative analytical procedures, including the analysis of materials, similar to the skin, in vivo. An acceptable procedure for gas chromatography are described in more detail in WO 99/45973, Donald .Roe et al, published September 16, 1999

Compositions in the form of a lotion, useful in the present invention are fluid (e.g. liquid) in an acceptable process conditions, for example, above 50°C or above 60°C or above 80°C or optional above 100°C., but are typically stagnant, i.e. solid at 25°C., i.e. at ambient temperatures. Compositions in the form of a lotion preferably have a final melting point (100% liquid) above potential "stressful" storage conditions that can be 45°or more.

the AK is used in this application not fluid, i.e. solid, means that 1 gram of material, placed Seredina round glass plate with a diameter of 15 cm, does not follow from the glass plate within 1 minute, if the glass plate is tilted at 45°, under conditions of 25°C and 50% relative humidity. The homogeneity of the compositions in the form of a lotion can be measured in accordance with test method ASTM D5, using a penetrometer to measure uniformity.

Non-aqueous means that the composition in the form of lotion or does not contain water, or contain only minor amounts of water, e.g. less than 5 wt.% or even less than 1 wt.%. However, such amounts relate to compositions in the form of lotion while receiving absorbent products, i.e. at the time of application of the composition in the form of lotion on absorbent product. Compositions in the form of lotion in accordance with the present invention can be rather hygroscopic and, therefore, may be able to absorb significant amounts of water from the surrounding atmosphere, in particular, environment with high relative humidity. Thus, if the absorbent product is kept for a relatively long period, for example, a few months or a few years, it is possible that the amount of water is contained in the composition in the form of a lotion, will increase by more than 5 wt.%.

It has been unexpectedly found that compositions in the form of lotion in accordance with the present invention provide proper operation in terms of workability and anti-stickiness. Indeed, it has been unexpectedly found that a specific combination of one or more compounds as described above with one or more connected the s In, as described above, and one or more accelerators of crystallization, as described above, provided that the mass ratio of compound(s) and accelerator(s) of crystallization is from 3:2 to 10:1, provide compositions in the form of a lotion which is easy to handle, even at high speed (for example, more than 400 absorbent products per minute), and which, importantly, are effective in reducing the adherence of feces or menstrual blood to the skin (anti-stickiness). Compositions in the form of a lotion which does not satisfy such conditions, it has been found that do not exhibit the desirable properties of the anti-stickiness and/or harden quickly enough to be considered as acceptable for use in the manufacture of absorbent products.

Compositions in the form of a lotion, consider how easy it is processed at high speed, where they quickly harden after application in the molten state on the basis, thus enabling fast processing basics in the later stages of the manufacture of absorbent products or wipes. Determining the temperature of crystallization of the composition in the form of lotion in accordance with the method of differential scanning calorimetry, as described in the test methods, it has been found that ideally displays the behavior of the composition in the form of lotion in practice, so what. how quickly it solidifies after application to the base and thus provides an excellent indication of the acceptability of the composition in the form of a lotion for use in high-speed process. Compositions in the form of lotion in accordance with the present invention showing the temperature of crystallization, which are representative of the compositions in the form of lotions, easily processed at high speed.

As indicated above, the composition in the form of lotion in accordance with the present invention exhibit the desirable properties of the anti-stickiness. Typically, the more effective the composition is in the form of a lotion, the lower the percentage of residual AVM transparencies. The average residual AVM less than 10%, according to the measurement method described in the test methods, is illustrative of a particularly good property of anti-stickiness.

Due to the properties of anti-stickiness, compositions in the form of lotion in accordance with the present invention can be reasonably used in ways to reduce the adhesion of faeces or menstrual discharge to human skin. Thus, the adherence of feces or menstrual discharge to the human skin can be reduced by providing a composition in the form of a lotion as described above, applying an effective amount of the composition in the form of a lotion is and facing the body surface of the base, which is used in the manufacture of, or as, or in the absorbent article for wearing by a user, and contacting the skin of a user with absorbent product. Through regular contact, movements of the user and/or under the influence of body heat, the composition is in the form of a lotion is transferred to the skin and limits the adherence of feces or menstrual blood.

Additionally, as a further useful effect, it was also found that the composition in the form of a lotion, useful in the present invention, exhibits the desirable properties of wetting the basis for hydrophobic and hydrophilic bases. Indeed, the composition in the form of a lotion preferably wet/spread on the hydrophobic or hydrophilic bases after application and therefore less likely to fall or erased with the basics during additional processing.

Additionally, it should be noted that the composition in the form of a lotion, useful in the present invention, provide the desired wetting properties of the basics in mind their acceptable hydrophilic character. Providing moisturizing properties of the basics is important, especially if used in an absorbent product such as a diaper: composition in the form of a lotion applied to the substrate, which is used as the top of the canvas, or it may be preferably there is TSS wetted to ensure that what fluids (e.g. urine) just go through the top fabric. This reduces the likelihood that body exudates will wash away the covering lotion, and not be absorbed by an absorbent inner layer.

Absorbent articles containing a base containing composition in the form of a lotion, as described in this application can be packaged with one or more wipes. In one of the westline, one or more wipes can be packaged in a first package, and one or more absorbent articles can be packaged in a second package. The first and second packages may be Packed together or may be held in the Assembly by other means. In another implementation, one absorbent product may be Packed with one or more napkins as one single package, which is particularly convenient for users that are in the path, where it may be desirable to carry only absorbent product and one or more wipes. Absorbent articles and wipes can also be sold together, for example, developed and/or advertised for sale and/or use together.

The method of applying a composition in the form of lotion in accordance with the present invention on the basis of

Compositions in the form of lotion in accordance with the present invention can be applied on the basis of using any known or otherwise effective method of distribution of the composition in the form of a lotion on the canvas. The composition in the form of lotion is typically applied from a melt on the basis of making or forming the upper sheet and/or cuffs for the legs and/or barrier cuffs and/or wings and/or side flaps absorbent products, or on a basis, which is used as napkins or her. It can also be the caused on the part of the strip applicator cushioning type.

Because the composition in the form of lotion melts at temperatures above ambient temperature, it is usually applied as a heated composition in the form of lotion on the canvas. Typically, the composition is in the form of a lotion is heated to a temperature in the range from about 40°° to about 100°C., preferably from 50° or 60°or even 90°C to about 100°C., prior to application to the substrate. Then, after application of the composition in the form of a lotion on the basis of making or forming the upper sheet and/or cuffs for the legs and/or barrier cuffs and/or wings and/or side flaps or used as a napkin, or in her, she is allowed to cool and harden quickly (e.g. less than 1 or 2 or 5) with the formation of the hardened coating on the substrate surface. Re-hardening of the composition in the form of a lotion can occur almost instantaneously, without the need for external cooling devices such as cooling rollers. However, such external devices, such as cooling rollers, before or after application of the melt, can be used if desired for additional acceleration of re-solidification. Non-limiting examples of methods of applying compositions in the form of a lotion on the basis include spraying, printing (e.g., flexographic printing), coating (e.g., contact the slotted floor and the floor, done with the help of engraving cylinder, extrusion or a combination of such methods of application. The composition is in the form of a lotion can be applied directly on the canvas, which is, or forms, or is used to make the upper of canvas and/or manilow foot and/or barrier manilow and/or wings and/or side valves absorbent products, or it can be applied to another material or component, which is then glued to the desired part of the absorbent products (e.g., calender roller).

The composition is in the form of a lotion may be applied uniformly or heterogeneously on facing the body surface of the base. Under facing toward the body surface of the base, as used in this application involve the outer surface or the outer surface of the base, which is used in contact with skin of the user. Under heterogeneous in this application involve the amount, pattern of distribution of the composition in the form of a lotion, which can vary based; including, for example, an implementation in which one or more parts of the treated substrate surface in this application can have more compositions in the form of a lotion than one or more other parts (for example, some parts contain higher the bulk composition in the form of a lotion than other parts of the, for example, at least 10% or at least 20% higher), including part of the surface not having a composition in the form of lotion on them. Such parts may be of any size, as defined below. Because the composition in the form of lotion, useful in the present invention, limits the adhesion of body exudates such as feces or menstrual periods in one implementation, it may, for example, be contained in such parts of the framework that constitutes, or forms, or used to manufacture top of the canvas or cuffs that are adjacent to areas of the skin of the user, which is typically contaminated with faeces and menstrual secretions. Thus, the composition is in the form of a lotion may, for example, be contained in those portions that are adjacent to the buttocks and/or the entire length of the depressions of the user who uses them, preferably also in the genital area. The amount of the applied composition in the form of a lotion may be the same for the rear third of the product (i.e. one third of the longitudinal extension absorbent products, starting with the outer edges of the frame in the rear waist area), the Central third of the products and the anterior third of the product. Alternatively, the amount of the applied composition in the form of a lotion may be different for the rear, Central and front third of absorbent products.

If the composition is in the form of l is Sion is applied unevenly, it can be applied periodically, i.e. intermittently. Can be used in any pattern including the pattern parts as described in the application above containing composition in the form of a lotion, including, for example, application of a pattern (or pattern parts having the shape of small drops (obtained, for example, by sputtering), separate figures of any shape or size, such as round, oval, rectangular, triangular, star-shaped, heart-shaped or shaped in the form of an animal (obtained, for example, a method of gravure printing), intermittent strips, which run in the longitudinal or transverse direction of the product, and so Also, the base may include different shapes and/or different size. Under alternating stripes mean the part where the composition is in the form of a lotion is applied in bands, divided into parts that do not contain the applied composition in the form of lotion.

Part, bands and/or other individual figures and/or drops can have a width of from 0.1 mm to about 50 mm, from 0.1 to about 30 mm, from 0.5 mm to about 50 mm, from about 0.5 mm to about 40 mm, from 2 mm to about 40 mm, from 2 mm to about 20 mm, from 2 mm to approximately 15 mm, or from 5 mm to approximately 20 mm, the distance between the stripes, not caused containing composition in the form of a lotion, can the have a width of from 0.1 mm to approximately 100 mm, from about 0.1 mm to about 50 mm, from 0.1 to about 30 mm, from 0.5 mm to about 50 mm, from about 0.5 mm to about 40 mm, from 2 mm to about 40 mm, from 2 mm to about 20 mm, from 2 mm to approximately 15 mm, or from 5 mm to approximately 20 mm Part in the form of strips and/or shapes and/or drops can have a length of at least 0.5 mm, or at least 2 mm or at least 5 mm In one implementation, if the parts containing composition in the form of a lotion, are in the form of strips, they may extend from one edge of the base to the opposite edge. Preferably, the strip may extend into the rear waist area basis to the extent that they also cover the buttocks and/or the greater part of the length of the troughs. If the composition is in the form of a lotion is applied in the form of a pattern of shapes, density and/or size of figures and/or the bulk composition in the form of a lotion contained in the figures may be higher, for example, 10% or 20% higher in parts of the surrounding areas (e.g., Central-thirds and posterior third absorbent products), which typically affect the faeces, zapachkala skin.

Compositions in the form of lotions typically applied to the substrate to transfer an effective amount to the skin, i.e. give the desired beneficial effects of the composition in the form of a lotion. For example, com is azizia in the form of a lotion can be applied on the basis for example, facing the body surface of the base, which is used in the manufacture of, or as, or in the absorbent product, such as top canvas absorbent products, in amounts in the range of from about 0.0015 mg/cm2(0.01 mg/inch2) to approximately 100,5 mg/cm2(100 mg/inch2), or from about 0.003 mg/cm2(0.02 mg/inch2) to approximately 12,4 mg/cm2(80 mg/inch2), or from about 0.02 mg/cm2(0.15 mg/inch2) to approximately of 7.75 mg/cm2(50 mg/inch2).

TEST WAYS

The way anti-tack properties of the anti-stickiness)

This method can be used in the n to evaluate the adhesion of dirt or exudates to the base by quantification of the percentage of residual artificial pasty stool ("AVM"), which remain on the transparent film after application of treatments lotion on the transparent film. AVM similar valid VMS children, was no cohesion, leading to the fact that part of the AVM remains on the transparent film, and part of the AVM is removed. The more effective the composition is in the form of a lotion, the lower the percentage of residual AVM transparencies.

Transparent film, which was used, was part of transparencies for copiers No. SOWING 00559 that supplies Corporate Express (Broomfield, CO). A transparent sheet of film is placed on a flat horizontal surface such as a table or bench, and the film was attached on the top and bottom to a flat surface using adhesive tape.

The template and a marker with a thin end used for marking the twelve seats of size 3 cm by 3 cm on separate sheets transparencies, i.e. up to twelve seats on the film sheet. For each test composition in the form of a lotion three places on transparent film was treated with a composition in the form of lotion. Three places also did not receive anti-adhesive processing that served as a negative control. The locations of various treatments, including non-treated areas may be randomized in all places transparencies. For each treated area, a predetermined number of 200-400 g/cm2compositions in the de lotion is applied to the center of the place using a rubber fingertip, not containing powder, catalogue number 56613-413, available from VWR Scientific, West Chester, PA. The applied composition in the form of lotion then sprayed all over the place (the boundaries of which were determined with the aid of the markings produced by template) using a rubber fingertip without powder, by placing rubber fingertip on the upper part of the agent or composition in the form of lotion and easy pokropivny rubber fingertip on the surface of the skin with the use of several movements from side to side and up and down within a time duration of 10 seconds. Studying the place of the angle of inclination, the person conducting the test shall ensure the formation of a uniform film over the entire area. The film left on the air, untouched, for about 1 minute before you move on to the next stage.

The syringe 1 ml, such as a syringe with catalogue number BD-309628, available from VWR Scientific, West Chester, PA, filled with ABM at room temperature, from which you have removed the air bubbles were placed in a calibrated analytical balance with an accuracy of up to four characters. Weight was registered. Syringe with AVM kept above the centre of the designated testing transparencies, at approximately 2 mm from the surface of the transparent film and approximately 0.2 ml of AVM were distributed on the transparent film by exiting by the piston and observing the markings on the syringe. AVM must form a homogeneous compact mound in the center place of testing. The syringe was weighed again on an analytical balance and the weight was recorded. The number of AVM, delivered on a transparent film was calculated by animania the second weight from the first.

A piece of paper for weighing 4 cm × 4 cm catalogue number 12578-201, available from VWR Scientific, West Chester, PA, was trioval on an analytical balance with an accuracy of up to four characters, centered over the bulk of the AVM to the test site on a transparent film and carefully lowered to the AVM using tweezers. Paper for weighing cannot be touched by the tips of the fingers, as this can transfer the fat on its surface. Then 500 g mass in the form of bottles, for example, with catalogue number 12766-518, available from VWR Scientific, West Chester, PA, which gives approximately 0.5 psi gravity, was placed over the paper for weighing, so that an AVM under the paper for weighing approximately centered under the weight. After 30 seconds of passing the 500 g mass was slowly raised. By using a pair of tweezers, paper for weighing slowly and carefully removed from the place of testing. Tweezers were placed in the lower right corner of the paper for weighing, and paper for weighing carefully shot towards the top-left corner of the paper for weighing. Remove paper to weigh what it should take about 1-2 seconds. After removal, paper for weighing prevented again on analytical scales, which were bagged and weight recorded to determine the number of remote AVM.

Above the stage was repeated until you have tested all the places on the transparent film, i.e. stage consisted of applying a composition in the form of a lotion, applying the AVM, overlay paper for weighing, blending weight and remove the paper for weighing. To control without treatment, application of an agent or composition in the form of a lotion missed and AVM inflicted directly on the transparent film. Mass percentage (%) residual AVM, remaining on the transparent film after the treatment, was calculated from measurements of the mass according to the equation

((AVM put AVM remote)/AVM applied) × 100.

Expected average value for the residual AVM and the standard error of the mean for each composition in the form of a lotion. With proper implementation of the method, the control without treatment typically gives a value of from about 30% to 50% residual AVM. To ensure reproducible results, the method of screening anti-stickiness should be carried out at room temperature 21°C±2°C and at a relative humidity of 30-50%.
