The term "disposable" as used herein in a general sense means a composition that is removed or discarded after a number of uses, preferably less than 25, more preferably less than 10, and most preferably less than 2 complete uses.

The term "nearly dry" means that the compositions of the present invention exhibit hydration of less than 0.95 g (0.95 gms), more preferably less than 0.75 g (0.75 gms), even more preferably less than 0.5 g (0 , 5 gms), even more preferably less than 0.25 g (0.25 gms), even more preferably less than 0.15 g (0.15 gms) and most preferably less than 0.1 g (0.1 gms). The determination of hydration is given below.

The personal care compositions of the present invention contain the following basic ingredients.

Water-insoluble substrate

The compositions of the present invention comprise a water-insoluble substrate which further comprises at least two layers, a nonwoven first layer and a second layer. In addition, the backing layers are preferably fine, which provides skin refreshment to the consumer when used. The layers are therefore "abrasion resistant". The term "abrasion resistant" means that it has an abrasion value greater than 15, preferably greater than 30, more preferably greater than 50, even more preferably greater than 70, and most preferably greater than 80, as described in the Abrasion Value Determination Methodology below. The nonwoven first layer and the second layer are in each case defined to have both an inner and an outer surface. In both cases, the inner surfaces of the layers are those that come into contact with the inner or innermost portion of the composition of the present invention, while the outer surfaces of the layers are those that come into contact with the outer or outermost portion of the composition. The orientation of the devices of the present invention can generally be defined such that any auxiliary layer is closer to the gripping side of the device (gripping side), while the layer

Rou • Φ · · 4 the fleece is to the side of the device which is to come into contact with the site to be cleaned and / or treated, for example the skin / site contact side. However, both sides of the composition are suitable for skin contact.

The water-insoluble substrate improves cleaning and / or medical treatment. This substrate has the same or different structure as the skin / site contact side. This substrate acts as an effective tool for foaming and peeling. When the substrate comes into physical contact with the skin or hair, cleansing and removal of dirt, make-up, dead skin and other damaged tissues helps significantly. In preferred embodiments, however, the substrate is not abrasive to the skin.

Non-woven beer layer

The water-insoluble substrate of the present invention further comprises a nonwoven first layer. This nonwoven first layer is preferably permeable to fluids. This nonwoven first layer is suitable for retaining the cleaning component within the composition. In addition, the nonwoven first layer is optionally suitable for contact with the skin, and therefore it is preferred that this layer be gentle on the skin.

Materials suitable for the nonwoven layer are selected from the group consisting of cellulosic nonwovens, bulk nonwovens, sponges (i.e., natural and synthetic), thin fibers, bulky webs, and combinations thereof. The nonwoven layer preferably comprises materials selected from the group consisting of cellulosic nonwovens, bulk nonwovens, thin fibers, bulky webs, foams, sponges, lattice foams, vacuum formed laminates, mules, polymeric webs, and combinations thereof. More preferably, the nonwoven layer comprises materials selected from the group consisting of cellulosic nonwovens, nonwoven nonwovens, thin fibers, nonwoven webs, and combinations thereof. The term 'nonwovens' means that the layer does not contain woven fibers, the layer possibly not containing fibers at all, such as thin fibers, foams, mules (thin cloths), etc. When the layer contains fibers, they are either irregular (i.e. randomly arranged) or carded ( that is, combed so that it is

oriented in one direction). In addition, the nonwoven layer is optionally a composite material which is composed of a combination of auxiliary layers, i.e. layers of irregular and carded fibers.

In preferred embodiments, the nonwoven first layer is apertured. The meshes of the nonwoven first layer of the water-insoluble substrate usually have a diameter of 0.5 mm to 5 mm. The meshes have a diameter of more preferably 1 mm to 4 mm. Less than 10% of the mesh of the nonwoven first backing layer is preferably outside said range. Preferably, less than 5% of the mesh of the nonwoven first backing layer is outside this range. For non-circular meshes, the term "diameter" means that their circumference is the same as the circumference of a circular mesh.

Inside the nonwoven first layer, the meshes typically occur at a frequency of 0.5 to 12 meshes per straight linear centimeter. The meshes on the cleaning surface are more preferably present at a frequency of 1.5 to 6 meshes per straight linear centimeter.

The meshes must be located at least inside the nonwoven first layer. It is not necessary for such meshes to protrude completely from one surface of the nonwoven first layer to the next. In addition, the meshes are optionally placed in auxiliary layers of the substrate so that the composition is apertured throughout its volume.

The meshes can be formed in a nonwoven first layer of a water-insoluble substrate, or a layer thereof that is woven. The meshes may optionally be formed in the nonwoven first layer only after the substrate containing the layer is completely woven.

The nonwoven first layer optionally contains a variety of natural and artificial fibers or materials. The term "natural" means that the materials are derived from plants, animals, insects or by-products of plants, animals and insects. The conventional starting material is usually a fibrous fabric which contains conventional synthetic or natural longitudinal textile fibers, or a combination thereof.

Each of said layers comprises at least two surfaces, namely an inner surface and an outer surface, each of which has the same or different texture and abrasion value. The compositions of the present invention preferably comprise substrates and thus layers that are gentle on the skin. The different textures of the substrates may result from the use of different combinations of materials or from the use of different production methods or combinations thereof. For example, a double textured water-insoluble substrate can be made which provides the personal care composition with the advantage of having a more abrasive side for peeling and a finer side for gentle cleansing and / or medical treatment. In addition, separate backing layers can be made to have different colors, helping the consumer to distinguish these surfaces.

In addition, each of the device layers as well as the devices themselves can be made in a wide variety of shapes and forms, including flat pads, thick pads, thin sheets, spherical tools, and irregularly shaped tools. The exact size of the layer depends on the desired use and properties of the composition, and the surface area ranges from 6,452 square centimeters (square inches) to hundreds of square centimeters (hundreds of square inches). Particularly suitable layer and composition shapes include, for example, a square shape, a circle shape, a rectangular shape, an hourglass shape, a glove shape or an oval shape having a surface area of 32.26 cm ² (5 in ² ) to 1290.4 cm ² ( 200 in ² ), more preferably 38.71 cm ² (6 in ² ) to 774.24 cm ² (120 in ² ) and more preferably 96.78 cm ² (15 in ² ) to 645.20 cm ² (100 in ² ) , and a thickness of 0.5 mm to 50 mm, preferably 1 mm to 25 mm and more preferably 2 mm to 20 mm.

The second layer

The compositions of the present invention further comprise a second layer. The second layer comprises materials selected from the group consisting of nonwoven materials, woven materials, sponges, and combinations thereof. This second layer is suitable for providing a differently textured side of the composition of the present invention and at the same time acts as an auxiliary carrier for the cleansing and therapeutically beneficial ingredient.

Nonwoven materials suitable for use in the second layer include, for example, those discussed in the Nonwoven First Layer section. In addition, suitable woven materials include, for example, polymeric meshes (mules). The mules contain fibers such as those mentioned as being suitable for the nonwoven first layer.

In preferred embodiments, the second layer comprises a woven material that comprises a synthetic material comprising nylon fibers. A more preferred synthetic material comprises nylon fibers that form a mule layer, wherein the auxiliary nylon fibers are further joined to form arcs on the mule layer.

Layer properties

Methodology for determining the value of abrasion

The abrasion value indicates the "abrasion resistance" property of the nonwoven first layer of the compositions of the present invention. The nonwoven first layer of the present invention is finely peeling, but not coarse to the skin. Determining the abrasion value therefore involves grinding the substrate along the test surface using mechanical equipment and then assessing the traces formed by grinding the test surface using various analytical techniques.

The following equipment is required for the determination methodology.

1. Martindale Model grinding and abrasion measuring device

103, serial nos. 103-1386 / 2 upwards. Martindale 07-01-88 manufactured by

James H. Heal and Co. Ltd. Textile Testing and QC Equipment. Area x 44 mm. Weight 1 kg.

2. Polystyrene cuttings coated with a size of 11x8 cm. The polystyrene layer on white High Impact Polystyrene, such as EMA Model Supplies SS-20201L, is cleaned.

3. Materials to be tested.

4. Gloss meter such as Sheem Tri-Microgloss 20-60-85.

Prior to sanding, polystyrene chips are prepared by removing the artificial protective coating from the side to be sanded and rinsing with ethanol (no cloth must be used). The cutting is placed on a non-abrasive surface and allowed to air dry. The polystyrene blank is then attached along the edges to the base of the Martindale wear gauge with tape. The chip is aligned to the center of the path of the grinding device so that the longer side of the chip is in the direction of movement. Substrate samples measuring 6.35 cm x 6.35 cm (2.5 χ 2.5) are cut. The substrate samples are attached to the brush leg of the Martindale wear meter with double-sided tape so that the direction of the instrument aligns with the direction of movement of the substrate. Mounting of the brush foot into the device is secured with screws. A weight of 1 kg is placed on top of the brush foot and the movement of the brush foot is ensured so that it runs only in one direction (forward and backward). The entire Martindale wear meter is covered with a protective screen. The instrument is set to 50 cycles per minute and started (frequency = 0.833 Hz). As soon as the device stops, the foot is removed and the polystyrene cutting is lifted from the base of the device. The polystyrene is marked with a label indicating the substrate used and placed in a plastic bag.

The cuttings are further analyzed. The sections are placed on a black structural paper background and at least 5 samples of the same substrate are analyzed to obtain a reproducible diameter. The gloss meter is placed orthogonally (so that the light beam is perpendicular to the grinding marks) and above the center of the side of the polystyrene blank that has been ground. An angle of 20 ° is selected and the sample is measured to give an abrasion value. The abrasion value decreases with increasing abrasive properties of the substrate.

Cleaning component

The compositions of the present invention comprise a cleaning component which further comprises one or more surfactants. The cleaning component is placed on a water-insoluble substrate, in certain embodiments the cleaning component is impregnated into a water-insoluble substrate, in another embodiment the cleaning component is applied to one or both surfaces of the water-insoluble substrate. The compositions of the present invention contain 10% to 1000%, preferably 50% to 600% and more preferably 100% to 250% of surfactant, based on the weight of the water-insoluble substrate. The compositions of the present invention also preferably contain at least 1 gram of surfactant, based on the weight of the water-insoluble substrate. Thus, the cleaning component can optionally be added to the substrate without requiring drying.

The surfactants of this cleaning component are preferably foaming surfactants. The term "foaming surfactants" means that when mixed with water and mechanically mixed, a foam is formed. Such surfactants are advantageous because more foam is important to consumers as an indicator of effective cleaning; in certain embodiments, the surfactants or combinations thereof are soft. The term "softness" means that the surfactants as well as the compositions of the present invention appear gentle on the skin, to the same extent as the fine synthetic alkyl glyceryl ether sulfonate (AGS) based on the surfactant, i.e. Synbar. Methods for measuring the softness, or conversely the irritancy, of surfactant-containing compositions are based on a skin barrier test. The finer the surfactant in this test, the less the protective layer of the skin is broken. The degree of disruption of the skin protective layer is determined by measuring the relative amount of radiolabeled water (3H-H ₂ O) (tritiated) that passes through the skin through the skin from the test solution into the physiological buffer contained in the diffusion chamber. This test is described by TJ Franz in J. Invest. Dermatol., 1975, 64, pp. 190-195, and further in U.S. Pat. No. 4,673,525 to Smali et al., Issued June 16, 1987, which are incorporated herein by reference in their entirety. Other test methodologies well known to those skilled in the art can also be used to determine the fineness of surfactants.

This therapeutically preferred component is placed on a water-insoluble substrate and contains 10% to 1000%, more preferably 10% to 500%, and most preferably 10% to 250% of a therapeutically preferred agent, based on the weight of the water-insoluble substrate. The therapeutically preferred agent is preferably selected from the group consisting of hydrophobic conditioning agents, hydrophilic conditioning agents, structured conditioning agents, and combinations thereof.

9% to 200%, and most preferably 10% to 100% of a therapeutically preferred agent, based on the weight of the water-insoluble substrate.

The hydrophobic conditioning agent is selected from one or more hydrophobic conditioning agents such that the weighted arithmetic mean of the solubility constant of the hydrophobic conditioning agent is less than or equal to 10.5. For example, it is known that based on the mathematical definition of a solubility constant, a desired weighted arithmetic average of the solubility constant, i.e. less than or equal to 10.5, can be obtained for a hydrophobic conditioning agent, provided that it contains two or more compounds and that one of the compounds has a solubility constant greater than 10.5.

Solubility constants are well known to those skilled in the art and are commonly used to aid in determining the compatibility and solubility of substances during their preparation.

The solubility constant of a chemical compound, δ, is defined as the square root of the cohesive energy density for that compound. The solubility constant of a compound is calculated from the tabulated values of heat of vaporization and molar volume of the individual components of that compound using the following equation,

and where ZjEj is equal to the sum of the heat of vaporization of the individual components, and

Zim, is equal to the sum of the molar volumes of the individual components.

Standard tables of evaporation heats and molar volumes of individual components are given for a wide range of atoms and groups of atoms in Bartoň, A. F. M. Handbook of Solubility Parameters, CRC Press, Chapter 6, Table 3, pp. 64-66 (1985), which is incorporated herein by reference

F., "A Method for Estimating Both the Solubility Parameters and Molar Volumes of Liquids", Polymer Engineering and Science, Vol. 14, no. 2, pp. 147-154 (February 1974), which is incorporated herein by reference in its entirety.

The solubility constants are governed by the mixing rule so that the solubility constant of a mixture of substances is given by the weighted arithmetic mean (i.e. the weighted average) of the solubility constants of the individual components of this mixture, cf. Handbook of Chemistry and Physics, 57th Edition, CRC Press, pp. C-726 (1976-1977), which is incorporated herein by reference in its entirety.

Solubility constants are expressed among the professional public in units (cal / cm ³ ) ¹ ' ² . The tabulated values of evaporating heats of individual components given in the Handbook of Solubility Parameters are given in units of kJ / mol. The tabulated heat of vaporization values are easily converted to cal / mol units using the following well known relationship,

J / mol = 0.239006 cal / mol and 1000 J = 1 kJ see. Gordon, A. J. et al., The Chemistry Companion, John Wiley & Sons, pp. 456-463, (1972), which is incorporated herein by reference in its entirety.

Methodology for determining the value of dynamic surface tension

The dynamic surface tension value is a measure of the amount of surfactant that is released from the composition when immersed in water.

Use a Sensadyne 9000 Surface Tensiometer (Series No. 0358, 4 mm large glass probe, 0.5 mm small glass probe) (or equivalent). The surface tension meter is calibrated with a sample of distilled water at room temperature and with a sample of ethyl alcohol at room temperature. Glass probes are placed in a sample of distilled water and the sample is analyzed. After stabilization, the surface tension value is recorded and this value is set on the device as the upper surface tension. The calibration is repeated for the ethyl alcohol sample and the recorded value is set on the instrument as the lower surface tension.

Prepare water with a ZCa + Mg concentration of 85.6 mg / l (5 gpg) and a temperature of 37 ° C ± 2 ° C and measure the surface tension. A 2000 ml beaker is then filled with this prepared water weighing 1000 g. The detergent is then lightly grasped by the corner, immersed in the beaker and pulled out of the water. This wetting is repeated four times, i.e. five wetings are performed in 10 seconds. It is important that the sample is not compressed or pinched, and it is important that the entire sample is immersed. After the fifth wetting, the sample is allowed to drip over the beaker for 15 seconds without shaking. Measure 140 g of water from a 2000 ml beaker into a 150 ml beaker and measure the value of the dynamic surface tension with a surface tension meter. This procedure is repeated each time with fresh batches of prepared water weighing 1000 g until the DSTV equals the surface tension of the prepared water from the initial measurement.

Methodology for determining the degree of surfactant dissolution

The rate of dissolution of the surfactant indicates the relative amount (ratio) of surfactant that is released from the composition upon contact with water, i.e. upon immersion, which is common in showering or bathing.

Fill ten 2000 ml beakers with tap water (ZCa + Mg 171.2 mg / l (10 grains per gallon)) and label one at a time. These beakers are placed in a 40 ° C (104 ° F) water bath and maintained until the water temperature in the beakers equalizes. The composition is then immersed six times and removed from beaker number 1, all for 5 seconds, and after the last removal, the sample is allowed to drip over the beaker for a further 15 seconds. It is important that the sample is not compressed or pinched, and it is important that the entire sample is immersed. The immersion / removal / drip cycle is repeated in sequence in each of the remaining beakers.

At the end of these cycles, 25 ml of the solution is dispensed from each beaker into a 100 ml graduated cylinder of the same marking, closable and graduated. Each cylinder is sealed with a parafilm and placed in the rotor by clamping it at a point where the cylinder scale shows 58 ml (or at a point relatively close to the center of the cylinder to ensure its balance during rotation). Each roller is rotated at 40 rpm for 1 minute. Each cylinder is allowed to stand for 2 minutes after removal from the rotor, and the volume of foam formed is measured in each cylinder. The degree of surfactant dissolution indicates the volume of foam in each beaker.

Methodology for determining the instantaneous volume of foam, foamability, foam dispersion time

The instantaneous foam volume (FLV) indicates the amount of foam produced by the compositions of the present invention in a one minute test. Foaming is a measure of the amount of foam created by the detergent under simulated showering conditions (i.e., under running water). The foam dispersion time indicates the time required to disperse the foam at a constant flow of water.

The test is performed with water with a ZCa + Mg concentration of 171.2 mg / l (10 grains per gallon) and a temperature of 40 ° C (104 ° F) at a water flow of 3.785 l / min (1.0 gallon per minute). The water is passed through a spray head from which 16 individual streams of water with a diameter of 5.08 cm (2 inches) flow. A plastic storage tank 58.42 cm (23 inches) long, 40.64 cm (16 inches) wide and 22.86 cm (9 inches) high is placed in a deep sink under running water (for example, a 55mm Rubbermaid plastic storage tray, 6 I (14.7 gallons)). Then one end of the storage tank is lifted so as to obtain an inclination of the longitudinal side of 30 to 45 degrees. Then one of the sides of the storage tank (longitudinal side measuring 58.42 cm (23 inches)) is cut to form a semicircular shape with a wall height of 10.16 cm (4) in the center, which allows easy access. A flexible bath mat equipped with suction cups, such as a Rubbeamaid Safti-Grip bath mat, is then placed in the storage tank and pressed against the bottom of the storage tank. The entire device is sprayed with hot water at a temperature of 40 ° C (104 ° F) before the actual measurement. As soon as the device gets wet, the water flow stops. The composition of the present invention, which contains a surfactant containing a cleaning component, is placed in the center of the bathing mat. If the device has a flat shape, its front edge is raised so as to allow the underside of the bottom. The composition is moistened by introducing a stream of water for 1 second and then sprayed with water while moving the composition in a circle. This showering and foaming of the composition lasts for another 4 seconds, which means that the total showering time is 5 seconds, and then the water flow is stopped. It is advisable to use a distribution valve because it maintains a constant flow, and through it the flow can be directed to the shower head or to the drain. After the initial 5 seconds of wetting and foaming of the composition, further foaming of the composition is initiated by abrupt movements with a frequency of 2 per second by soaking the composition in water at the bottom of the mat after each movement, which keeps the composition and the mat moist. Each movement covers the total distance of the bathing mat, from one end to the other, to the edges of the bathtub. After a total time of 30 seconds (5 seconds with water shower and 25 seconds without water shower), the 30 second foaming cycle is repeated. The product is then removed from the bath without · · ···· · · · · · · η • · · · · · · ···· · · · · • · · ··· ·· »·· ·· · · · ® · ··· <>

would be squeezed and placed in a beaker. The foam-filled tub is removed from the sink and its contents are poured through a strainer covered with a sieving cloth (100% cotton, high-performance sieving cloth, cut to a size of 40.64 cm x 58.42 cm (16 inches χ 13 inches)). All the foam is removed and transferred to a beaker suitable for measuring the volume of foam, while the water trapped in the container under the strainer is weighed to check the water flow. Carefully lift the strainer from the strainer and transfer the foam to the beaker previously filled with foam. Once all the foam has been transferred to the beaker, the level is equalized and its volume is read. This volume indicates the instantaneous volume of the foam.

Next, the foam is weighed and the density of the foam is calculated using its weight and volume.

Then the bath is returned to the spout and the steps described above are repeated with the previously used agent. The foamability of the composition corresponds to the total foam volume after two minutes of foaming. To ensure consistency, tests are performed with two standard products, at least once at the beginning and once at the end (daily) of the test group. Standard products are the compositions of Comparative Examples A and B. The standard product provides an average of 1250 ml of foam with a density of 0.058 g / ml.

In a foaming test lasting 2 minutes, the compositions of the present invention preferably provide 500 ml to 4000 ml, more preferably 750 ml to 3000 ml and most preferably 1000 ml to 2500 ml of foam.

After determining the foaming, the dispersion time of the foam can optionally be determined. All the foam is transferred back to a strainer covered with a sieving cloth (top diameter 29.21 cm (11.5), diameter at the base 11.43 cm (4.5), depth 9.40 cm (3.7), holes with a diameter 3 mm with spacings of 2.54 cm (one inch), the total number of holes: 120 holes are evenly distributed around the perimeter and 37 holes are evenly distributed along the bottom of the strainer) and this is placed in the sink. Once the foam-filled colander is placed under running water (at a flow rate of 3.785 L / min (1.0 gpm) at 40 ° C (104 ° F)), time measurement begins. The strainer rotates under a stream of water and the timing stops when the last part of the foam is lost. The time required to remove the foam indicates the time the foam dispersed.

Methodology for determining the power-to-fineness ratio

The thickness of the substrates and the fineness of the substrates are interdependent. Fineness has several independent components. One of the ingredients is a kind of "pillow" softness. This means that when the base is pressed by hand or finger, it behaves in much the same way as a pillow under body pressure, which thus contributes to rest. In this test, power parameters are measured using the following equipment:

1. Instron Model 1122 Compression and Tensile Tester (or equivalent);

2. Instron serial number 445 (range 200 grams) compression load cell (or equivalent),

3. flat cover plate, connectable to load cell,

4. flat base plate, under load cell,

5. 4.76 cm (1.875 inch) diameter punch, and

6. hammer.

Substrate samples are formed using a 4.76 cm (1.875 inch) diameter punch and hammer, and if the edges of the discs are compressed inelastically during the punching method, the edges are carefully fluffed to return to their original shape. The cover plate is set to the starting position, the Instron load cell is calibrated and the compression mode is started, in which the plate drops at a rate of 1.27 cm / min (0.50 inches / minute). The Instron is controlled manually or by a computer until a pressure greater than 4.650 g / cm ² (30 grams / in ² ) is reached, recording data quickly enough (computer recommended) that correspond to heights at different pressures during descent. The cover plate is then lowered to the base plate, which is the point that corresponds to zero height. It is important that the cover plate and the base plate are parallel, i.e. that the contact occurs at all points at once.

Once the instrument is zeroed, the cover plate returns to a position that provides sufficient space to insert the disk-shaped substrate sample. This disk is placed in the center of the system board. The Instron is then set up to perform complete compression of each substrate sample. The Instron turns on and the height and force exerted by the cover plate is continuously recorded throughout the mode. Once the sample compression is complete, repeat this procedure with new samples of the same substrate, until a reliable average is obtained. The average height above the base plate at compression values of 0.775 g / cm ² (5 gms / in ² ) and 4.650 g / cm ² (30 grams / in ² ) is equal to the thickness at 0.775 g / cm ² (5 gms / in ² ) and 4.650 g / cm ² (30 grams / in ² ). The density-fineness ratio is calculated as the thickness ratio at 0.775 g / cm ² (5 gms / in ² ) divided by the thickness at 4.650 g / cm ² (30 grams / in ² ).

Methodology for determining the crepe ratio

During creping, substrates are created that have patterns of peaks and dimples. Creping brings to the substrate properties such as bulk, softness, increased ability to remove impurities, improved air and water transfer necessary for foam, compressive flexibility and a visually pleasing appearance. The individual substrates can be creped and preferably combined with other substrates, creped or uncreped, and it is also possible to crepe multilayer compositions. This methodology can be used to determine the degree of creping for individual substrates or compositions. There are a number of different ways to measure the degree of creping. The aim of this methodology is to measure the thick dimension of the substrate, which is represented by the distance from the top of the peak to the bottom of the well, and to measure the thin dimension of the substrate, which is represented by the "wall thickness" of the substrate.

The first layer preferably has a crepe ratio of 3 to 45, more preferably the lower limit of the crepe ratio is 4.1, even more preferably 4.2 and most preferably 4.25. The upper limit of the crepe ratio is more preferably 20, even more preferably 15, and most preferably 12. These lower and upper limits may optionally be combined to provide an optimal range.

First, the thickness of the substrate to be tested is measured at a compression and relaxation hysteresis (CRHV) value of 0.775 g / cm ² (5 grams / in ² ) according to the Method for determining the power-to-fineness ratio, as discussed above. Thus, several sample pieces of the same substrate measuring a few square centimeters (square inches) are cut. Then, a feather knife-shaped probe (0.508 mm (0.02 inches) thick and 7 mm wide) is attached to the top of the Instron Model 1122 Compression and Tensile tester (or equivalent) in a vertical position. The blurred end of the knife is defined by a 0.508 mm x 7 mm (0.0200 inch x 7 mm) rectangular cross section that is parallel to the base plate. The Instron series number 445 load cell (range 100 g (100 gms)) with the cover plate in the starting position is calibrated. Compression mode starts, in which the board drops at a rate of 0.508 cm / min (0.20 inches / minute). The Instron is controlled manually or by a computer until a force greater than 25 grams is reached, recording data quickly enough (computer recommended) that corresponds to heights at different pressure values during descent. The cover plate is then allowed to lower until the end of the knife comes into contact with the base plate, a point which corresponds to zero height. It is important that the fuzzy end of the knife and the base plate are parallel, that is, that contact occurs at all points at once. The probe returns to a position that provides sufficient space to insert the substrate sample. The substrate is placed on the base plate so that the flat knife probe descends for the longest possible time without contact with any part of the substrate. The Instron is then lowered to compress this furrow portion of the sample with the knife blade. The specimen can be moved during the slow descent of the knife blade to ensure that the thinnest possible substrate size is measured. This is the wall thickness. The Instron is started and, until a force of 50 grams is reached, the height and force are continuously recorded, preferably by means of a computer output. This procedure is repeated with new substrate samples until a reliable average is obtained. The average height above the base plate at a thickness of 10 grams is then recorded. The crepe ratio is determined as the ratio of the thickness of the substrate at 0.775 g / cm ² (5 grams / in ² ) measured by the Method for determining the power-to-fineness ratio, divided by the thickness measured by a probe in the shape of a fuzzy knife at a thickness of 10 grams.

Methodology for determining the surface to saturation ratio

Compositions of the present invention that contain a therapeutically beneficial ingredient have a therapeutically beneficial ingredient applied mainly to the surface of the substrate. The term "mainly on the surface of the substrate" means that the surface to saturation ratio is greater than 1.25, preferably greater than 1.5, more preferably greater than 2.0, even more preferably greater than 2.25, and most preferably 2.5. The surface to saturation ratio is the ratio resulting from measuring the preferred agent on the surface of the substrate. These measurements are obtained by Attenuated Total Reflectance (ATR) Four-transform infrared spectroscopy (ATR) FT-IR Spectroscopy, which is well known to those skilled in the art of analytical chemistry.

Many conventional methods of applying conditioning agents to substrates utilize methods and / or articles unsuitable for the purposes of this invention. For example, a method in which a substrate fabric is immersed in a liquid bath of a treatment agent and then pressed on rollers, referred to as "dip and press" treatment, and which applies the treatment agent to the entire substrate and thus does not provide an opportunity for use during use. effective direct transfer of the composition off the fabric and to another surface. In addition, many compositions of the present invention utilize the application of a sufficient dose of conditioning agents to substrates to provide an effective whole body benefit, i.e., dose ratios of 100% to 200%, based on the weight of the dry substrate, are usually required. Known personal care tools that use these high doses substantially avoid the controversial aesthetic issues that arise from these high doses by evenly distributing the dose throughout the substrate, including the interior of the substrate. It has been found that high doses of conditioning agent can be maintained on the surface of the composition, which advantageously provides an opportunity for direct transfer of preferred agents from the substrate to the surface to be treated during use, thereby providing improved aesthetics.

The method of obtaining these measurements is as follows.

Instrument settings: Spectrometer type BioRad FTS-7, manufactured by Bio Rad

Labs, Digital Laboratory Division, Cambridge, MA, is used to record the infrared spectrum. These measurements usually involve 100 scans at a resolution of 4 cm ^-1 . The optics comprise a flat 1,047 radian (60deg) ZnSe ATR crystal, manufactured by Graseby Specac, Inc., Fairfield, CT. Data are measured at 25 ° C and analyzed using the Grams 386 program, which is distributed by Galactic Industries Corp.,

Salem, NH. Before starting the measurement, the crystal is purified with a suitable solvent. The sample is placed on an ATR crystal and loaded with a weight of 4 kilograms.

Experimental method:

(1) Measure the reference (background) spectrum of the cleaned, air-dried cuvette.

(2) First, a substrate is selected which does not contain the preferred agents and which contains the outer surface of the composition. The substrate is placed on top of the ATR crystal with the outer surface facing the crystal. First, the substrate is placed flat on the measuring point and then a weight of 4 kg is placed on top of the substrate. The spectrum is then measured (typically 100 scans at a resolution of 4 cm ^-1 ). The substrate behaves as an internal standard because it measures the absorbance of the substrate itself. The main peaks and wavelengths of the substrate are determined.

(3) The process is repeated for a substrate composition that contains preferred agents.

The heights of the primary peaks for the preferred reagent are determined, which are the highest peaks recorded which either do not correspond to the substrate peak recorded in the previous step or which correspond to the substrate peak recorded in the previous step but which show the largest percentage increase in absorbance due to the presence of conditioning agent. The wavelengths and absorbances of several peaks of the preferred reagent are recorded.

First, two paper towels are weighed separately and the weight of each is recorded. One paper towel is placed on a flat surface (such as a laboratory table). A sample of the composition is placed on top of this towel. A second paper towel is placed on top of the composition sample. Next, a Lexan and then a weight of 2000 g (or a combination of weights equal to 2000 g) is placed on top of a coated sample of the composition. Wait for 1 minute. After this time, the weights (or combination of weights) and Lexan are removed. Weigh the top and bottom paper towels and record their weight.

Hydration is calculated by subtracting the initial weight of the paper towel from the final weight (after 1 minute) for both the top and bottom paper towels. The weight differences calculated for the top and bottom paper towels are added. Assuming that mixed compositions are tested, hydration is obtained by averaging the total weight differences.

Method of preparing emulsions:

The hydrophobic phase is heated to 70 ° C, the hydrophobic active ingredients are added and the mixture is stirred until homogeneous. In addition, the hydrophilic phase is mixed with the hydrophilic active ingredients in a separate vessel and, if necessary for their dissolution, gently heated. The mixture is then slowly added to the hydrophobic phase with stirring. The mixture is homogenized (a high shear mixer, ultrasonic homogenizer, or high pressure homogenizer such as a Microfluidizer from Microfluidics Corp.). The mixture is immediately applied to the surface of the substrate or cooled rapidly to room temperature in ice or ice water. If it is necessary to maintain chemical stability, they are stored in a controlled environment in a nitrogen atmosphere.

Example 75

The skin cleanser is prepared as follows.

four grams of the cleaning component of Example 11 are applied to one side of a permeable, fusible fabric that contains low-melt, heat-sealable polyamide fibers. This is a permeable Wonder Under fabric manufactured by Pellon, available from H. Levinson & Co., Chicago, IL. The cleaning component is applied to an oval surface measuring 13 cmx 18 cm. The cleaning component is air dried. A layer of polyester fleece with a basis weight of 67.8 g / m ² (2 oz / sq yd) cut to the same size as the fabric is placed on the fusible fabric. Polyester fleece with basic weight

67.8 g / m ² (2 oz / yd ² ) contains a mixture of fibers with an average thickness of 23 μm (23 microns) and 40 μm (40 microns), at least some of which are crimped. The web thickness is 0.584 cm (0.23 in.) Measured at 0.775 g / cm ² (5 gsi). It is assumed that the fleece is thermally bonded without the use of glue. A layer of nonwoven material is placed under the fusible fabric to form the other side of the device. The nonwoven is a spun blend of 70% rayon and 30% PET fibers, bonded with a styrene-butadiene adhesive, which is entangled in a stream of water to form 2 mm diameter holes and which has a basis weight of 70 g / m ² (70 gsm). The device has the shape of an oval with a size of 122 mm χ 160 mm. The layers are bonded by spot bonding in a grid pattern by heat pressing using pressure plates of a Sentinel Model 808 type thermal bonding device available from Sencorp, Hyannis, MA. Each of the point links measures 4 mm in diameter and 51 separate point links are evenly spaced here. The product is edged and ready for use.

Example 76

The skin cleanser is prepared as follows.

The cleaning component of Example 11 is applied to one side of the first substrate by continuous extrusion through an applicator head in four lines spaced 20 mm, 40 mm and 20 mm apart, measured across the width of the fabric, resulting in a pair of parallel lines on each side of the fabric. The cleaning component is extruded at a rate yielding 4.4 grams of cleaning component per composition. The substrate is a spun blend of 70% rayon and 30% PET fibers, bonded with a styrene-butadiene adhesive, which is entangled in a stream of water to form 2 mm diameter holes and which has a basis weight of 70 g / m ² (70 gsm). The second fabric, i.e. the fleece layered in a stream of air, of massive, low density, is placed over the first substrate, which brings it into contact with the surfactant-containing layer. The web contains a mixture of 30% PET fibers weighing 1.67 mg / m (15 denier), 35% bicomponent fibers weighing 0.33 mg / m (3 denier) with a PET core and PE sheath, 35% bicomponent fibers weighing 1, 11 mg / m (10 denier) with the same core-shell composition, and has a basis weight of 100 g / m ² (100 gsm). The fabrics are continuously fed to an ultrasonic splicing machine, which forms a dot pattern comprising a grid formed by dot bonds with a diameter of 4 mm, which are evenly distributed throughout the fabric. The fabric is cut into individual devices, which measure 120 mm χ 160 mm and have the shape of a rectangle with rounded corners, and has a total of 51 point ties per device.

Example 77

The skin cleanser and composition is prepared as follows.

Three grams of the skin treatment component of Example 34 was applied to the composition of Example 75, half on each side. The component is applied in the form of a hot liquid (at a temperature of 60 ° C to 70 ° C) evenly by painting on the surfaces of the composition, half of the component on each side of the composition.
