The first layer of non-woven fabric is made according to European patent application EP EP published 27 March 1996.
It may be a polymeric reticulated sponge as described in 702550A1, which is incorporated herein by reference in its entirety. Such polymeric reticulated sponges are made of a large number of extruded tubular reticulated meshes made of strong flexible polymers, such as nylon or addition polymers of olefin monomers and polyamides of polycarboxylic acids. Comprising layers. The first layer of nonwoven may be a composite material, such as a composite material containing a film and a formed film. Preferably, such molded film comprises a plastic that tends to be soft to the skin. Suitable soft plastic molded films include, but are not limited to, polyolefins such as low density polyethylene (LDPE). Where the first layer of non-woven fabric comprises a molded plastic film, in such cases the first layer of non-woven fabric is perforated such that the layer is liquid permeable, eg having large pores or microscopic. It is preferable to have holes. In one embodiment, the first layer of non-woven fabric comprises a film formed of plastic having only micropores. The surface modification of the micropores, ie the male side, is preferably located on the inner surface of the second layer and faces the inside of the substrate, ie the cleansing / therapeutic benefit component. In certain embodiments involving pores with petaloid edge surface deformations, without being limited by theory, manual pressure is applied to the article when the surface deformations of the pores face the surfactant-containing cleansing / therapeutic benefit component. When applied, the petaloid edges of the surface deformation fold inward to create multiple valves on the inner surface of the layer, where the effect is to actually deliver the cleansing / therapeutic benefit ingredients contained within the article. It is believed that it is applied to the inner surface of the article and thus prolongs the useful life of the article.

In another embodiment, the first layer of non-woven fabric comprises a plastic molded film having both micropores and large pores. In such an embodiment, the first layer of nonwoven is provided with the cloth-like feel of such a microporous film.
It is well suited to contact the area to be cleaned and / or therapeutically treated. Preferably, in such an embodiment, the surface deformation of the fine pores faces the opposite of the surface deformation of the large pores of the nonwoven layer. In such an example, due to the three-dimensional thickness formed from the surface deformation, the large holes maximize the wetness and bubbling of the entire article, and the surface deformation is constantly compressed and decompressed during use of the article. , It is thought that a whirlpool-like thing (bellows) is made. In any case, the first layer of nonwoven fabric comprising forming the film is preferably at least about 100 holes / cm ^2, more preferably at least 500 holes / cm ^2, even more preferably at least about 1000 holes / Cm ² , and most preferably at least about 1500 holes / cm ² of the substrate. Preferred embodiments of the present invention include about 5 cm ³ / cm ² · sec to about 70 cm ³ / cm ² · sec, more preferably about 10 cm ³ / cm ² · sec to about 50 cm ³ / cm ² · sec and most preferred. Is about 15
Mention may be made of a first layer of nonwoven having a water flow rate of from cm ³ / cm ² · sec to about 40 cm ³ / cm ² · sec.

Suitable examples of formed films and composites containing formed films useful in the first layer of the nonwoven fabric of the present invention include US Pat. No. 4,342,314 (August 1982).

All of which are incorporated herein by reference, but are not limited thereto. Further, the first layer of nonwoven may be a formed film composite material comprising at least one formed film and at least one non-woven fabric, the layer being formed in a vacuum. Suitable formed film composite materials include, but are not limited to, vacuum laminated composite formed film materials formed by combining a carded and fluffed polypropylene nonwoven having a basis weight of 30 gsm with the formed film. Moreover, the first and second layers of nonwoven fabric (as well as the additional layers) are preferably adhered to each other to maintain the integrity of the article. This bond may be a point bond (eg, hot point bond), a connection in a continuous (eg, laminating, etc.) or discontinuous pattern, or a bond at the outer edge (perimeter) of the layer and / or at a separate location or combinations thereof. May consist of Geometric shapes and patterns, such as diamonds, circles, squares, etc., may also be formed on the outer surface of the layer, arranging the bonds to result in an article. It is envisioned in the articles of the present invention that the first layer and any additional layers may be surface modified to form a single composite layer having two sides of different materials. Thus, in practice, a water-insoluble substrate can be construed to include a single composite layer having a surface or surfaces that have a dual texture. In any event, the adhesive area present between the first and second layers of the nonwoven does not exceed about 50% of the total surface area of the layer, preferably not above about 15%,
More preferably it does not exceed about 10%, and most preferably it does not exceed about 8%.

Each layer discussed herein comprises at least two sides, an inner side and an outer side,
Each surface may have the same or different texture and texture. Preferably, the article of the present invention comprises a substrate, and thereby a skin soft layer. However, different texture substrates can be made by using different material combinations or different manufacturing processes or combinations thereof. For example, a water-insoluble substrate woven with two components has the advantage of having a rougher side for exfoliation and a softer, absorbable side for gentle cleaning and / or therapeutic treatment. Can be created to provide a personal care article. In addition, each layer of the substrate can be manufactured to be different in color, which makes it easier for the user to identify the surface. Further, like the article itself, each layer of the article may be manufactured in a wide variety of shapes and shapes, including flat pads, thick pads, thin sheets, ball-shaped tools, irregular-shaped tools, and the like. The exact size of the layer depends on the desired application and the characteristics of the article and is about 1 surface area.
It may range from square inches to about several hundred square inches. Particularly advantageous layer and article geometries include surface areas of about 5 in ² to about 200 in ² , preferably about 6 in ² to about 120 in ² , and more preferably about 15 in ² to about 100 in ² , and about 0.5 mm ²

Examples include, but are not limited to, squares, circles, rectangles, stamped shapes, glove-shaped or oval-shaped shapes having a thickness of about 20 mm.

Second Layer The article of the present invention further comprises a second layer. The second layer comprises a material selected from the group consisting of non-woven fabrics, fabrics, sponges, and combinations thereof. This second layer is useful for providing an article of the present invention with a surface having a different texture, as well as acting as an additional carrier for cleansing and / or therapeutic benefit ingredients. Nonwovens suitable for use in the second layer include, but are not limited to, those previously discussed in the section Nonwoven first layer section. Further, suitable fabrics include, but are not limited to, polymeric nets (scrims). The scrim comprises fibers such as those mentioned as suitable for the first layer of nonwoven. In a preferred embodiment, the second layer comprises a fabric comprising a synthetic material including nylon fibers. More preferred synthetic materials include nylon fibers formed in a scrim layer having additional nylon fibers, the additional nylon fibers bonded to the scrim layer in an arc on the scrim layer.

Method of Measuring Characteristic Abrasivity Value of Layer The abrasivity value indicates the "non-abrasiveness" of the first layer of the nonwoven fabric in this article. The first layer of the nonwoven fabric of the present invention gently exfoliates the skin but is not rough. Therefore, determining the abradability value involves rubbing the substrate along the test surface using a mechanical device and examining the resulting scratch marks on the test surface using different analytical techniques. . The following equipment is required for the measurement method. 1. Martindale Toothbrush Wear and Abrasive Tester: Model 1

Supply 2020-1L. 3. The substrate to be examined. 4. Gloss meter, eg Sheen Tri-Microgloss 2
0-60-855

Remove the plastic protective coating from the surface to be scratched, rinse with ethanol (without tissue) and prepare the polystyrene pieces for scratching. Place the pieces on an unrubbed surface and allow the pieces to dry in air. The polystyrene pieces are then taped along the edges to the Martindale Wear Tester. Position the strip in the center of the path of the polishing device along the length of the strip in the direction of movement. Cut into 2.5 ″ × 2.5 ″ square substrate samples. Attach the base material sample to the polished base of Martindale Wear Tester with double-sided tape and align the machine direction of the base material with the moving direction. Secure the polishing base part in the device with the screws provided.
Make a groove with a weight of 1kg on the top of the polishing base part to ensure that the polishing base moves in one direction (forward and backward). Cover the entire Martindale Wear Tester with a safety screen. Set and run for 50 cycles per minute. (Frequency 0.833 Hz). Once the machine has stopped, remove the base piece and lift the polystyrene strip from the base of the machine. Label the polystyrene to indicate the substrate and store in a plastic bag. Then analyze the small pieces. Place the strip on a background of black machine paper and analyze at least 5 samples of the same substrate to obtain a reproducible average value. Center the gloss meter orthogonally (with the light beam at the right angle to the scratch) and on the scratched surface of the polystyrene strip. The angle of 20 ° is selected and the sample is measured to obtain the wear value. As the abradability value decreases, the scratch or polish properties of the substrate increase.

Therefore, the cleansing component may be added to the substrate without the need for a drying step. The cleansing component surfactant is preferably a foaming surfactant. As used herein, "foaming surfactant" means a surfactant that produces a foam or foam when mixed with water and mechanically agitated. Such surfactants are preferred because increased foam is important to the consumer as it exhibits a cleansing effect. In some embodiments, the surfactant or combination of surfactants is mild. As used herein, "mild" means that the surfactant is a synthetic bar soap based on mild alkyl glyceryl ether sulfonic acid (AGS) surfactants, similar to the articles of the invention, i.e. synbar. ) Is equivalent to a mildness to the skin. A method for measuring the mildness or conversely the irritation of articles containing surfactants is based on the skin barrier destruction test. In this test, the milder the surfactant, the less the skin barrier is destroyed. Skin barrier destruction is radiolabeled (tritiated) coming through the physiological buffer in the diffuser chamber through the epidermis of the skin from the test solution for measuring the water (3H-H ₂ O) relative amount.

Method of Measuring Dynamic Surface Tension Value Dynamic surface tension value measures the amount of surfactant released from an article when submerged in water. Sensadyne 9000 surface tensiometer (serial number 0358, 4 mm
A large glass probe, a small glass probe of 0.5) (or its equivalent). Calibrate using distilled water samples at room temperature and ethyl alcohol samples at room temperature. Insert a glass probe into the distilled water sample and let the tensiometer analyze the sample. Observe the surface tension value, and set the value as a high surface tension value as soon as it stabilizes. Repeat the scale setting for the ethyl alcohol sample and set the surface tension as a low surface tension. Surface tension is measured using 5 gpg and water set at 37 ° C ± 2 ° C. Then fill a 2000 ml beaker with 1000 g of prepared water. The cleansing article is then held loosely at the corners and the entire sample is submerged in water in a beaker and the sample is removed from the water. This submersion is repeated 4 more times, so as to complete 5 submersions in 10 seconds. It is important to soak the entire sample in water, being careful not to squeeze or fold it. After 5 submersions, lift the sample onto a beaker and drain excess water from the sample for 15 seconds, taking care not to shake the sample. Pour 140 g of water from a 2000 ml beaker into a 150 ml beaker,
The dynamic surface tension value is measured using a tensiometer. Continue submersion in a 1000 g batch of fresh water and obtain surface tension measurements (DSTV) for each sample until the initial surface tension measurement of the prepared water is equal to DSTV.

Determining Surfactant Solubility Surfactant solubility is the release of surfactant contained in an article into water when exposed to water, that is, when submerged as experienced in a shower or water bath. Measure the percentage that is given. Start by filling ten 2000 ml beakers with tap water (10 grains per gallon), followed by labeling them. Maintain the beaker temperature in a 104 ° F water bath until the temperature of the water in the beaker equilibrates. Next, the article is held on the beaker 1 and submerged, and the article is taken out 6 times in 5 seconds, and after 6 times submersion, the excess water is taken out and dropped into the beaker for another 15 seconds from the article. It is important to submerge the entire sample, being careful not to squeeze or fold it. Submersion / withdrawal cycle of the article in each of the remaining beakers /
The dropping cycle is repeated continuously. Once these cycles are complete, pour 25 ml of solution from each beaker into a cylinder that can be sealed with a correspondingly labeled 100 ml cap. Seal each cylinder with parafilm and place the cylinder on the rotator so that the cylinder grips the rotator at 58 ml (or relatively near the center of the cylinder) to help balance the cylinder during rotation. . Rotate each cylinder at a speed of 40 revolutions per minute. Remove each cylinder from the rotator and let stand for 2 minutes. Measure the volume of foam emerging in each cylinder. Surfactant solubility indicates the volume of foam in each beaker.

Method for Measuring Flash Foaming Capacity, Foaming Capacity, Foam Dissipation Time Flash Foaming Volume (FLV) refers to the amount of foam produced by an article of the present invention during 1 minute. Foaming capacity measures the amount of foam produced by a cleansing article under simulated shower conditions (ie, in the presence of running water). Bubble disappearance time (LDT
) Indicates the time required for the bubbles to disappear under constant water flow. The test is run at a water hardness of 10 grains per gallon, a temperature of 104 ° F. and a water flow rate of 1.0 gallons per minute. Water is flowed from the tip of a sprinkler which ejects 16 independent water streams within a range of 2 inches in diameter. Place a plastic storage box 23 inches long x 16 inches wide x 9 inches high in a deep sink close to running water (eg, 14.7 gallons of Rubbermaid plastic storage) box). Then, raise one end of the storage box to make a long vertical inclination at an angle of about 30 to 45 degrees. Cut out one side of the storage box (along the 23 inch side) in a semi-circular pattern leaving a wall height of only 4 inches in the center for easy access. A flexible bath mat having a suction cup, for example, a rubber maid safety grip (
Lay the Safti-Grip) bath mat face down on the bottom of the storage box. All units are continuously sprayed with 104 ° C. hot water before the actual measurement. Stop running water as soon as the unit gets wet. In the center of the bath mat is placed an article of the present invention containing a surfactant containing a cleansing ingredient. If the article is flat in shape, fold up the front edge of the article so that it is wet on the underside. After pouring water on the article for 1 second to wet it, the article is sprayed with water while reciprocating the article in a circular shape on the unit. Continue spraying for an additional 4 seconds and whipping the article so that the water is sprayed for a total of 5 seconds, then stop the water flow. A diverter lever that directs the flow towards the showerhead or drain while maintaining flow is convenient. The first 5 to wet and whip the item
After a second, the experimenter reciprocates the article once every 2 seconds to vigorously foam further, submerging the article into the water after each reciprocation to keep the article and mat completely wet. Each reciprocating motion spans the entire distance from the end of the bath mat to each end of the box. After a total elapsed time of 30 seconds (5 seconds spraying water and 25 seconds without spraying water), repeat the 30 seconds whipping cycle again. Next, the article is removed from the tub without squeezing and placed in a beaker. Remove the foamed box from the sink and pour the contents of the box into a cheesecloth-covered strainer (100% cotton, sturdy cheesecloth, cut into approximately 16 inches by 23 inches). Remove all foam while receiving water in the basin under the strainer, place in a beaker suitable for measuring foam volume, weigh the water and check the water flow rate. Carefully lift the cheesecloth off the strainer and transfer the foam to the pre-foamed beaker. As soon as all the foam has been transferred to the beaker, measure the foam height in the beaker and measure the foam volume. This volume is the flash foaming volume.

After that, the mass of the foam is measured, and the density of the foam is calculated using the mass and the volume of the foam. The box is then returned to the sink and the above steps are repeated with the previously used articles. Two
The total volume of foam during frothing for minutes is the foaming capacity of the article. To ensure consistency, at least two standard products are tested at the beginning and end of each (daily) group test. The standard product is the article of Comparative Examples A and B. Standard products typically make an average of about 1250 ml of foam at a foam density of about 0.058 g / ml. Articles of the invention are preferably about 500 ml per 2 minutes based on the foaming capacity test.
To about 4000 ml, more preferably about 750 ml to about 3000 ml, and most preferably about 1000 ml to about 2500 ml of foam. Once the foaming capacity is determined, the foam extinction time may be determined. Return the entire foam volume to the strainer covered with cheese cloth and stabilize the strainer in the sink (top opening: diameter 11.5 "; bottom circular diameter: 4.5"; 3.7 "). Depth, 3 mm holes 1 inch apart, total number of holes: 120 holes evenly distributed on the circumferential surface, and 37 holes evenly distributed on the bottom of the strainer) once filled with bubbles Start the time measurement by placing the strainer under running water (1.0 gpm at 104 ° F.) Rotate the strainer under running water and stop the time measurement as soon as the bubbles have completely disappeared. The time required for the bubbles to disappear is the bubble disappearance time.

Bulk-Flexibility Measurement Method The bulk of the substrate and the flexibility of the substrate are related. Flexibility has several independent,
It has a contributing element. One of the elements is the type of "pillow-like" flexibility. That is, when the force is applied by hand or finger pressure, the substrate is easily squeezed in much the same way that the pillow is squeezed to support placing a body part on it. This test measures the parameters related to bulkiness using the following equipment: Instron model 1122 compression and tension tester (or equivalent); 2. Instron serial number 445 (200 grams at maximum scale) compression load cell (or equivalent); 3. Flat top plate, attachable to load cell; 4. Flat bottom plate, below load cell; 6.875 inch diameter driller; and 6. Hammer A base material sample is cut using a punch with a diameter of 1.875 inches and a hammer. In the example where the drilling process presses the disc edge inelastically, the edge is carefully fluffed to restore the original dimensions. With the top plate in place, calibrate the Instron load cell and run in compression mode at a descent rate of 0.5 inch / min. If the final compression is at a pressure of 30 g / in ² , the Instron may be manually or computer controlled and, while descending, quickly enough to determine the height at various compression values. Collect data (recommend computer help). Then move the top plate down until it contacts the bottom plate at a point where the height was set to zero. It is important that the top and bottom plates are parallel and all points are in contact at the same time. Once the instrument is zeroed, the top plate is retracted over the bottom plate to allow sufficient space for the disc sample disk to be sandwiched therebetween. The disk of substrate is then placed in the center of the bottom plate. The Instron is then set to fully compress each substrate sample once. Then switch on the Instron and record the height and force of the upper plate continuously. Once the sample compression is complete, repeat compression of a new sample of the same substrate as needed to obtain a reliable average. Each average height above the lower plate in the compression value of 5 g / in ² and 30 g / in ^2, is equal to the thickness of 5 g / in ² and 30 g / in ^2. The bulk-flexibility ratio is calculated as the ratio of the thickness at 5 g / in ² divided by the thickness at 30 g / in ² .

Shrinkage Ratio Method Shrinkage results in a substrate having peaks and valleys. Shrinkage is valuable to the substrate by providing bulkiness, flexibility, enhanced debris removal capability, enhanced air and water movement necessary for foaming, compressible resilience, and visually pleasing appearance Can be added. The individual substrates can be crimped, optionally combined with other substrates that are crimped or uncontracted; and the multilayer article can also be crimped. This method can be used to define the amount of shrinkage for individual substrates or finished articles. There are many different ways to measure the amount of shrinkage. The purpose of this method is to measure the bulk, thickness dimension, which represents the peak-to-bottom dimension of the substrate; and the thin dimension, which represents the "wall thickness" of the substrate. The first layer preferably exhibits a shrinkage ratio of about 3-45, more preferably the lower limit of the shrinkage ratio is about 4.1, more preferably about 4.15, even more preferably about 4.2.
And most preferably about 4.25. The upper limit of the shrinkage ratio is more preferably 20.
, Even more preferably 15 and most preferably about 12. An optimum range may be given by combining such a lower limit and an upper limit.

First, the thickness of the substrate to be investigated is measured with a compression-relaxation histesis value (CRHV) of 5 g / in ² according to the bulk-flexibility method described above. A few inches square is then measured and several representative pieces of the same substrate are cut. Then, in the vertical position,
A flat tip knife probe (0.02 inch thick x 7 mm wide) is mounted on top of an Instron Model 1122 compression tension tester (or equivalent). A plane of the knife end is defined by a 0.0200 inch x 7 mm rectangular cross section parallel to the lower plate. Correct the Instron serial number 445 load cell (100 g maximum load setting) with the top plate intact. Operate the Instron tester in compression mode at a descent rate of 0.20 inch / min. The Instron may be manually controlled or computer controlled as long as the final compression reaches a force of at least 25 grams and is sufficient to determine the height at various compression values during descent. Recover data quickly (suggesting computer help). Then move the top plate down until the knife end contacts the bottom plate and the zero point height is set. The flat end of the knife and the bottom plate must be parallel and contact at all points simultaneously. Retract the knife probe over the bottom plate to allow enough space for inserting the substrate. The substrate is then placed on the bottom plate so that the descending flat-ended knife probe can descend for as long as possible without contacting any part of the substrate. The Instron is then actuated so that the blade of the knife can press against this recess of the sample. The sample may be manipulated while gently lowering the blade of the knife to ensure that the dimensions of the thinnest substrate possible are measured. This is the wall thickness. The Instron is then actuated, continuously recording height and force, preferably while printing on a computer, until a force of about 50 grams is reached. Additional substrate samples are similarly examined to obtain a reliable average. The average height above the lower plate at a compression value of 10 grams of force is then recorded. Then 5 g measured by the method of bulk-flexibility
The shrinkage percentage is determined as the ratio of the substrate thickness in / in ² divided by the thickness measured with a flat end knife probe at a force of 10 grams.

Surface-to-Saturation Ratio Methodology Articles of the invention that include a therapeutic benefit component have the therapeutic benefit component substantially on the surface of the substrate. By "substantially on the surface of the substrate", the ratio of surface saturation to saturation is about 1.25, preferably about 1.5, more preferably about 2.0, even more preferably about 2.25. , And most preferably greater than 2.5. The ratio of surface to saturation is the ratio of the measurement of benefit agent on the surface of the substrate. Such a measurement is an attenuated total reflectance (ATR) F well known to those skilled in the art of analytical chemistry.
Obtained from T-IR spectroscopy. Many conventional methods for applying conditioning agents to substrates employ process and / or product rheology that are not suitable for the purposes of the present invention.
For example, a step of immersing the base fabric in a liquid bath of a conditioning agent and then squeezing the base fabric via a squeezing roll, a so-called "immersion and squeeze" process, applies the conditioning agent through the entire base, Therefore, it does not provide the opportunity for the composition to drop off the fabric and be effectively transferred directly to another surface during use. Moreover, many of the articles of the present invention utilize sufficient loading of the conditioning agent on the substrate to provide effective systemic benefits, typically about 100 to about 100, based on the weight of dry substrate. 200%
Requires a loading rate of. Known personal care devices that use such high loading levels deal with aesthetic problems that can result in such high loading by evenly distributing the load through the substrate, including within the substrate. Is essentially avoided. Applicants have surprisingly found that a high loading of conditioning agent can be maintained at the surface of the article, and thus, advantageously, can be treated during use while delivering improved aesthetics with the compositions of the present invention. It has been found that there is an opportunity to transfer the beneficial agent directly from the substrate to the surface to be processed. The procedure for obtaining measurements is as follows:

Instrument Setup: Infrared spectra are collected using a Bio-Rad FTS-7 spectrometer (manufactured by Digital Laboratory Division of Bio-Rad Labs, Cambridge, Mass.). Generally, the measurements consisted of 100 scans at 4 cm ^-1 resolution. The collection optics

cac, Inc.) flat type 60 degree ZnSe ATR crystal. Data was collected at 25 ° C and used for Gram 386 software (Galactic Industries Co., Salem, NH).
rp)) was used for analysis. The crystals are washed with a suitable solvent prior to the measurement. The sample is placed on the ATR crystal and supported with a constant mass of 4 kilograms.

Experimental Procedure: (1) Measure the reference (background) spectrum of a clean, air-dried cell. (2) First, select a substrate to which the beneficial substance is not applied, a selected substrate including the outer surface of the article. Place the substrate on top of the ATR crystal with the outer surface facing the crystal.
First, the base material is laid flat on the measurement plate. Then a load of 4 kg is placed on the substrate. The spectrum is then measured (typically 100 scans at 4 cm ^-1 resolution).
. The substrate thus acts as an internal standard, as it confirms the absorption of only the substrate. Check the major peaks and wave numbers of the substrate. (3) Repeat the procedure for the substrate to which the benefit agent has been applied. Does not correspond to a previously observed substrate peak; or may correspond to a previously observed substrate peak,
Confirm the height of the major peak of the beneficial agent, which is the highest peak observed, which shows the greatest percentage increase in absorption due to the presence of the conditioning agent. The wavenumbers and absorptions of the peaks of several beneficial substances are recorded. (4) Select the spectrum of the substrate from the spectrum measured in step 3 that occurred at the wavenumber determined in step 2, but does not correspond to one of the major beneficial agent peaks selected in step 3. Record the absorption from the selected wavenumber and absorption spectrum in step 3. (5) The ratio of the peak height of each beneficial substance measured in step 3 to the peak height of the base material measured in step 4 is calculated. The highest number in the group represents the ratio of surface to saturation for the article. Here are some examples:
