Description

Personal care article {PERSONAL CARE ARTICLES}

Personal care products, in particular cleansing and conditioning products, have been commercially available in many forms such as bar soaps, creams, lotions and gels. Typically, these products have been tried to satisfy many criteria for being recognized by consumers. Such criteria include cleansing effects, skin feel, mildness to the skin, hair and eye mucosa, and volume of foam. An ideal personal cleansing agent should gently cleanse the skin or hair, cause little or no irritation, and should not accumulate excessively or excessively dry on the skin or hair after frequent use.

It is also highly desirable to deliver such cleansing and conditioning benefits using disposable products. Disposable products are convenient as there is no need to carry or store cumbersome bottles, bars, tubs, tubes and other congested forms, including cleansing products and other products that can provide therapeutic or cosmetic benefits. In addition, sponges, washcloths, or widely reused cleansing tools may exhibit undesired characteristics due to bacterial propagation, unpleasant odors, and other repeated use, which may result in a disposable product compared to the use of such tools.

Detailed description of the invention

As used herein, the term “disposable” refers to an article that is disposed of or disposed of after a limited number of uses, preferably less than 25, more preferably less than about 10, and most preferably less than about 2 total uses. It is used in a general sense.

As used herein, the phrase "substantially dry" indicates that the article of the invention is less than about 0.95 gms, preferably less than about 0.75 gms, more preferably less than about 0.5 gms, even more preferably less than about 0.25 gms, more More preferably less than about 0.15 gms, most preferably less than 0.1 gms. Determination of water retention is discussed later.

The personal care article of the present invention includes the following essential ingredients.

Water Insoluble Substrate

The article of the present invention contains a water-insoluble substrate further containing at least two layers, namely a nonwoven first layer and a second layer. Preferably, the base layers are soft but, when used, are soft and refreshing to the skin of the consumer. Thus, the layers are "scouring". The term "non-peelable" as used herein means that the layers have a polishing value of greater than about 15, preferably greater than about 30, more preferably greater than about 50, even more defined by the polishing value methodology detailed above. Preferably greater than about 70, most preferably greater than about 80. In some cases, however, the first and second layers, which are nonwovens, are defined as having both inner and outer surfaces, respectively. In both cases, the inner surface of the layers is towards the inner or innermost portion of the article of the invention, while the outer surface of the layers is towards the outer or outermost portion of the article. In general, the orientation of the article of the invention is such that the second layer is closer to the gripping side of the article (i.e. the bag side) and the non-woven first layer is to be cleansed and / or therapeutically treated, eg skin It may be determined closer to the side of the article in contact with the / site contact surface. However, both sides of the article are suitable for contact with the skin.

Without being limited by theory, it is believed that such water-insoluble substrates enhance cleansing and / or therapeutic treatments. The substrate may be the same or different texture on each side such that the bag side of the article has the same or different texture as the skin / site contact surface. The substrate can serve as an efficient foaming and exfoliation tool. By being in physical contact with the skin or hair, the substrate significantly aids in cleansing and removing dirt, makeup, dead skin, and other residues. However, in a preferred embodiment the substrate does not exfoliate the skin and is not abrasive to the skin.

Nonwoven fabric first layer

The water-insoluble base material of this invention contains the 1st layer which is a nonwoven fabric further. This nonwoven first layer is preferably fluid-permeable. This nonwoven first layer is useful for drawing or retaining the cleansing component in the article. In addition, the first layer, which is a nonwoven fabric, may also be in contact with the skin when the layer is preferably soft to the skin.

Suitable materials for the nonwoven layer are selected from the group consisting of cellulosic nonwovens, non-lofty nonwovens, sponges (ie, both natural and synthetic), molded films, non-lofty batting, and combinations thereof. Preferably, the nonwoven layer is cellulosic nonwoven, non-lofty nonwoven, molded film, non-lofted batting, foam, sponge, net foam, vacuum-formed laminate, scrim, polymeric net, and It contains materials selected from the group consisting of combinations thereof. More preferably, the nonwoven layer contains materials selected from the group consisting of cellulosic nonwovens, non-locked nonwovens, molded films, non-lofted batts, and combinations thereof. "Means that the layer does not contain fibers woven into the fabric, but the layer need not contain any fibers, such as molded films, sponges, foams, scrims and the like. If the layer contains fibers, the fibers may be random (ie, randomly arranged) or carded (ie, combed to oriented in one major direction). The nonwoven layer can also be a composite material consisting of a combination of additional layers of random or carded fibers, ie several plies.

In a preferred embodiment, the nonwoven first layer is apertured. The openings of the first layer, which is a nonwoven of water insoluble substrate, will generally range from about 0.5 mm to 5 mm in average diameter. More preferably, the openings will range in size from about 1 mm to 4 mm in average diameter. Preferably, the openings outside this size range of the first layer of nonwoven of the substrate will be about 10% or less. More preferably, the openings outside this size range of the first layer of nonwoven will be about 5% or less. For openings whose shape is not circular, the "diameter" of the opening corresponds to the diameter of the circular open portion having the same surface area as the open portion of the non-circular opening.

In the first layer of nonwoven, the openings will generally be present at a frequency of about 0.5 to 12 openings per straight line of one centimeter. More preferably, the openings in the cleansing surface will be present at a frequency of about 1.5 to 6 openings per straight line of one centimeter.

The openings must be disposed in the first layer which is at least nonwoven. These openings need not be completely through from one surface of the first layer of nonwoven to another. However, such a case is also possible. In addition, the openings may or may not be disposed in additional layers of the substrate to open in the entire volume of the article.

Openings may be formed in a first layer that is a nonwoven of a water-insoluble substrate when such substrate or layer thereof is molded or processed. Alternatively, the openings may be formed in the first layer of nonwoven after the substrate containing the layer is fully molded.

The first layer, which is a nonwoven, may contain various natural and synthetic fibers or materials. The term "natural," as used herein, means that the substance is derived from a plant, animal, insect or by-product of a plant, animal, and insect. Typical base starting materials are generally fibrous webs containing any common synthetic or natural woven length fibers, or a combination thereof.

The first layer, which is a nonwoven, may also be the polymeric mesh sponge described in European Patent Application No. 702550 A1, published March 27, 1996, which is incorporated herein by reference in its entirety. Such polymeric mesh sponges comprise a large number of plies of extruded tubular mesh nets made from polymers with strong elasticity, such as additive polymers of olefin monomers and polyamides of polycarboxylic acids.

The first layer, which is a nonwoven, may also contain a molded film and a composite material, ie a composite material containing the molded film. Preferably, such shaped films contain plastics that tend to be soft on the skin. Suitable soft plastic molded films include, but are not limited to, polyolefins such as low density polyethylene (LDPE). When the nonwoven fabric first layer thus contains a plastic molding film, it is preferable that the nonwoven fabric first layer is opened by, for example, large opening or microopening so that the layer is fluid permeable. In one embodiment, the nonwoven first layer contains only microopened plastic molded film. The surface modifications of the microopenings, ie the male faces, are preferably located on the inner surface of the second layer, preferably towards the interior of the substrate, ie towards the cleansing and / or therapeutic benefit components. In certain embodiments involving openings in which the surface deformation edges are in the form of petals, without limitation, the application of pressure to the article by hand when the surface deformation of the openings is directed towards the surfactant containing cleansing component / therapeutic benefit component The petal-shaped edges of the silver surface deformations fold inward to create numerous valves on the inner surface of the layer, which has the effect of metering out the cleansing component / therapeutic benefit component contained within the article, thereby reducing the useful life of the article. It is thought to extend.

In another embodiment, the nonwoven first layer comprises microopenings and macroopened plastic molding films. In this embodiment, the nonwoven first layer is suitable for contacting the site to be cleansed to provide a texture similar to the fabric of such microopened film. Preferably, in this embodiment, the surface modifications of the micro openings face opposite surface modifications of the macro openings on the first layer which is a nonwoven fabric. In this case, the macro openings are believed to maximize the overall wetting / foaming of the article, resulting in rich foaming, by the three-dimensional thickness formed from the surface deformations under constant compression and decompression during use of the article.

In some cases, the first layer, which is a nonwoven fabric containing a molded film, is preferably at least about 100 openings / cm 2 substrate, more preferably at least 500 openings / cm 2 substrate, even more preferably at least about 1000 openings / cm 2 substrate, Most preferably it has at least about 1500 openings / cm 2. More preferred embodiments of the invention range from about 5 cm 3 / cm 2 -s to about 70 cm 3 / cm 2 -s, more preferably from about 10 cm 3 / cm 2 -s to about 50 cm 3 / cm 2 -s, most preferably about 15 And a first layer, which is a nonwoven, having a water flow rate of between cm 3 / cm 2 -s and about 40 cm 3 / cm 2 -s.

Suitable molded films and composite film-containing composite materials useful for the first layer of the nonwoven of the present invention are, but are not limited to, US Pat. No. 4,342,314, which is incorporated herein by reference in its entirety (Radel et al., Aug. 3, 1982). , And co-pending US application Ser. No. 08 / 326,571 and PCT application US95 / 07435, filed Jun. 12, 1995, published Jan. 11, 1996, and US Pat. No. 4,629,643. (Curro et al., Dec. 16, 1986). Further, the nonwoven first layer may be a molded film composite material comprising one or more molded films and one or more nonwovens, where the layer is vacuum formed. Suitable molded film composite materials include, but are not limited to, vacuum laminated composite molded film materials formed by combining carded polypropylene nonwovens having a basis weight of 30 gsm with a molded film.

In addition, the first layer and the second layer (and any optional additional layers) that are nonwoven are preferably bonded to each other to maintain the integrity of the article. Such bonding can be accomplished in spot patterns (eg, thermal point bonding), continuous bonding (eg, in discrete patterns or by bonding at the outer edges (or periphery) of the layers and / or at discrete locations or combinations thereof. , Laminated, etc.). The bond may also be arranged such that geometrical and pattern examples, such as diamonds, circles, squares, etc., are formed on the outer surface of the layers and the resulting article.

It is also conceivable that the first layer and any additional layers in the article of the invention can be surface modified to form a single composite layer having two sides of different textures. As a result, the water-insoluble substrate can be interpreted to contain a single composite layer having a double textured surface or surface.

In some cases, the combined area present between the first and second layers of nonwoven fabric is about 50% or less of the total surface area of the layer, preferably about 15% or less, more preferably about 10% or less, most Preferably it is about 8% or less.

Any of the layers discussed herein include two or more surfaces, i.e., inner and outer surfaces, each of which may have the same or different textures and abrasiveness. Preferably, the article of the invention comprises a substrate and its layers soft to the skin. However, the differentiation of the substrate texture can be achieved by the use of different combinations of materials or the use of different manufacturing methods or by combining them. By way of example, a water-insoluble substrate imparted with a double texture can be made to provide the advantage that a personal care article has a more abrasive face for exfoliation and / or a softer and adsorptive face for gentle cleansing and treatment treatments. . In addition, separate layers of the substrate can be made to have different colors, helping the user to distinguish the surface.

In addition, each layer of the article, as well as the article itself, can be made in a wide variety of shapes and forms, including flat pads, thick pads, thin sheets, ball shaped tools, and non-uniform shaped tools. The exact size of the layers will depend on the desired use and characteristics of the article, and the surface area size may range from about 1 square inch to about hundreds of square inches. Particularly convenient layers and article shapes include, but are not limited to, a surface area of about 5 in ² to about 200 in ² , preferably about 6 in ² to about 120 in ² , more preferably about 15 in ² to about 100 in. ² , about 0.5 mm to about 50 mm, preferably about 1 mm to about 25 mm, and more preferably about 2 mm to about 20 mm square, round, rectangular, hourglass, glove or egg-shaped Include.

Second layer

The article of the present invention further contains a second layer. The second layer contains a material selected from the group consisting of nonwovens, wovens, sponges, and combinations thereof. This second layer is useful for providing different textures to articles of the present invention as well as acting as additional carriers for cleansing ingredients and / or therapeutic benefit ingredients.

Nonwovens suitable for use in the second layer include, but are not limited to, those defined above in the first layer section which is a nonwoven. In addition, suitable nonwovens include, but are not limited to, polymeric nets (scrims). Scrims include fibers such as those mentioned as suitable for the first layer of nonwoven.

In a preferred embodiment, the second layer contains a woven fabric containing a synthetic material containing nylon fibers. More preferred synthetic materials contain nylon fibers molded into a scrim layer with additional nylon fibers, to which additional fibers are bonded to form an arc on the scrim layer.

The nature of the layer

Polishing value methodology

The polishing value indicates the "non-sticking" property of the first layer, which is a nonwoven of the article of the present invention. The first layer of nonwoven fabric of the present invention moderately exfoliates but is not rough to the skin. Thus, determining the degree of polishing value involves rubbing along the test surface of the substrate using a mechanical device, and then examining scratch marks of the results produced on the test surface using different analysis techniques.

The following apparatus is required for the methodology.

1. Martindale Toothbrush Wear and Abrasion Tester: Model 103, serial number 103-1386 / 2 and above. Martindale 07-01-88, James H. Heal and Co. Ltd. Produce. Textile testing and QC instruments. Foot area of the machine: 43 × 44 mm. 1 Kg weight.

2. 11 x 8 cm of capped polystyrene pieces. A clean general purpose polystyrene layer on white, high impact polystyrene, for example, EMA model no. SS-20201L.

3. The substrate to be tested.

4. Glossimeters, eg Sheen Tri-Microgloss 20-60-85.

By removing the plastic protective coating on the side to be scratched and rinsing with ethanol (no paper is used), a piece of polystyrene is prepared for scratching. The pieces are placed on a non-abrasive surface and the pieces are dried in air. Then, along the edge using tape, a piece of polystyrene is attached to the bottom of the Martindale Abrasion Tester. In the center under the path of the scrubbing device, the pieces are arranged with the length of the pieces in the direction of motion. Cut a 2.5 "x 2.5" substrate sample. The substrate sample is attached to the scrubbing foot of the Martindale abrasion tester, using double-sided tape, arranged in a reciprocating direction in the machine direction of the substrate. Secure the scrubbing foot assembly in the instrument with the provided screws. A 1 kg weight is applied to the top of the scrubbing foot assembly and ensures that the scrubbing foot only moves in one direction (front and rear). The entire Martindale abrasion tester is covered with a safety screen. Set the machine to run 50 cycles per minute and run it (frequency = 0.833 Hz). Once the machine has stopped, remove the foot assembly and lift the polystyrene piece from the bottom of the machine. The name tag indicating that the substrate is used is attached to polystyrene and stored in a plastic bag.

After that, the pieces are analyzed. A piece of black building paper is laid out on top of it, and five or more identical substrate samples are analyzed to obtain a reproducible average. With respect to the scratched side of the polystyrene piece, a glossmeter is placed at right angles (so that the ray is perpendicular to the scratches) and at the center. Select the 20 ° angle and measure the sample to determine the polishing value. As the degree of polishing decreases, the scratchiness or peeling property of the substrate increases.

The surfactant of the cleansing component is preferably a foaming surfactant. As used herein, the expression “lathering surfactant” means a surfactant that, when combined with water, produces a foam or foam when mechanically stirred. Such surfactants are preferred because the foam is important to the consumer as an indication of the cleansing effect. In certain embodiments, the surfactant or combination of surfactants is mild. As used herein, the expression “mild” is used to compare not only surfactants but also articles of the present invention to synthetic bars, ie synbars, based on mild alkyl glyceryl ether sulfonate (AGS) surfactants. It is meant to be gentle to the skin. The method of measuring the mildness or vice versa of a surfactant containing article is based on the skin barrier destruction test. In this test, the milder the surfactant, the less break the skin barrier. Skin barrier destruction is measured by the relative amount of radiation-labeled (tritium-labeled) water (3H-H ₂ O) that flows from the test solution through the skin epidermis into the physiological buffer contained in the dialysate chamber. The test is described in TJ Franz, J. Invest. Dermatol. , 1975, 64, pp. 190-195; And US Pat. No. 4,673,525 to Small et al., Issued June 16, 1987.

Solubility parameters are well known to formulation chemists having ordinary skill in the art and are routinely used as guidelines for determining compatibility and solubility of materials within the formulation process.

The solubility parameter δ of a chemical compound is defined as the square root of the aggregation energy density of that compound. Typically, the solubility parameter of a compound is calculated using the following formula, from the table values of the heat of vaporization of the addition functional groups and the contribution to the molar volume of the components of the compound:

Where Σ _i E _i = sum of vaporization heat contributed by additional functional groups, and

Σ _i m _i = sum of the molar volumes contributed by the addition functional groups.

The standard tabulation of the heat of vaporization and molar volume at which additional functional groups contribute to a wide variety of atoms and groups of atoms is described by Barton, AFM Handbook of Solubility Parameters , CRC Press, Chapter 6, Table 3, pp, incorporated herein by reference in its entirety. . Collected in 64-66 (1985). The solubility parameter equation is described in Fedors, RF, "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).

Solubility parameters follow a mixture law such that the solubility parameter for a mixture of substances is determined by the weighted arithmetic mean (ie, weighted average) of the solubility parameters for each component of the mixture. Handbook of Chemistry and Physics , 57th edition, CRC Press, p. See C-726 (1976-1977).

Formulation chemists typically use and record solubility parameters in units of (cal / cm 3) ^1/2 . Contribution table values of the addition functional groups to the heat of vaporization in the Handbook of Solubility Parameters are reported in kJ / mole. However, the vaporization table values can be easily converted to cal / mole using the following well known correlation:

1 J / mol = 0.239006 cal / mol and 1000 J = 1 kJ

Dynamic Surface Tension Methodology

The dynamic surface tension value measures the amount of surfactant released from the article as it is immersed in water.

A Sensadyne 9000 surface tension meter (serial number 0358, 4 mm large glass probe, 0.5 small glass probe) (or equivalent thereof) is obtained. Calibrate the tension meter using distilled water samples and room temperature ethyl alcohol samples at room temperature. A glass probe is placed in a distilled water sample and the sample is analyzed by a tension meter. Observe the surface tension value and correct the value as high surface tension as soon as it stabilizes. The calibration is repeated for the ethyl alcohol sample and its surface tension is corrected as low surface tension.

Set to 5 gpg and 37 ° C. ± 2 ° C. with water and measure surface tension. The 2000 ml beaker is then charged with 1000 g of prepared water. The edges of the cleansing article are then slightly grasped, the entire sample is submerged in the beaker and the sample is withdrawn from the water. Repeat this soaking 4 or more times and allow 5 soaking to be completed within 10 seconds. It is important to submerge the entire sample, taking care not to squeeze or ground the sample. After soaking five times, the sample is lifted over the beaker and excess water is drained from the sample to the beaker for 15 seconds, taking care not to shake the sample. 140 g of water from the 2000 ml beaker is poured into a 150 ml beaker and the dynamic surface tension value is measured using a tension meter. Continue to immerse in the 1000 g batch of fresh water to obtain the interfacial tension measurement (DSTV) value of each sample until the DSTV is equal to the initial interfacial tension measurement of the prepared water.

Surfactant Solubility Methodology

Surfactant solubility measures the rate at which the surfactant contained in the article is released upon immersion, which occurs when exposed to water, ie upon shower or bath.

Fill 10 2000 ml beakers with tap water (10 grains per gallon) and start numbering them consecutively. The beaker is held in water at 104 ° F. until the temperature of the water in the beaker is in equilibrium. The article is then picked up on beaker 1 and submerged 6 times within 5 seconds, and after the 6th submersion and removal, excess water from the article is allowed to fall into the beaker for 15 seconds. It is important to submerge the entire sample, taking care not to squeeze or ground the sample. The immersion / removal cycle / drip cycle of the article is repeated successively in each remaining beaker.

At the completion of this cycle, 25 ml solution from each beaker is poured into a correspondingly numbered 100 ml capped graduated cylinder. Each cylinder is sealed with a parafilm, and each cylinder is raised on the rotator by holding the cylinder with the forceps in a 58 ml position (or relatively close to the center of the cylinder) to assist in balancing the cylinder during rotation. Each cylinder is rotated at 40 rpm for 1 minute. Each cylinder was removed from the rotor and left alone for 2 minutes. Measure the foam volume appearing in each cylinder. Surfactant solubility is expressed in the volume of foam in each beaker.

Instantaneous foam volume, foam forming ability, foam disappearance time methodology

Instantaneous bubble volume (FLV) indicates the amount of foam produced within 1 minute by an article of the present invention. Foam forming capacity measures the amount of foam produced by the cleansing article under the shower conditions to be simulated (ie, in the presence of running water). Bubble disappearance time (LDT) indicates the time required for bubbles to disappear under constant flowing water.

The test is conducted using water having a hardness of 10 grains per gallon, a temperature of 104 ° F. and a flow rate of 1.0 gallons per minute. Within 2 inches of diameter, the water flows through a sprinkler head that ejects 16 separate streams of water. Place a plastic storage box 23 inches long by 16 inches wide by 9 inches high (eg, a Rubbermaid 14.7 gallon plastic storage box) in a deep sink adjacent to running water. Thereafter, one end of the storage box is raised, tilted in the longitudinal direction, and inclined at about 30 to 45 degrees. Cut one side of the storage box into a semicircle (along side 23) so the wall height is only 4 "from the center for easy access. Flexible bath mat with suction plate, e.g. Rubbermaid Safti-Grip Bath Mat Turn over to the bottom of the storage box, spray the entire unit continuously with hot water at 104 ° F. before actual measurement, once the unit is wet, stop the flow of water. The article of the invention is placed in the center of the bath mat If the article is of a flat design, the front edge is held up so that the bottom is moistened, soak the article in water for 1 second, and then spray the article with water. While rubbing the article circularly on the unit, spray the article for an additional 4 seconds so that water is sprayed for a total of 5 seconds. After high foaming, the flow of water is stopped, a diverting lever that maintains the flow but directs it to the shower head or drainage is useful, after wetting and foaming the article for the first 5 seconds, the article is subjected to 2 per second The experiment is started by immersing the article in water to the bottom of the mat after each stroke to vigorously foam more at multiple stroke rates and keep the article and mat completely wet. From end to end, reaching each edge of the box After 30 seconds of total elapsed time (5 seconds of water spray and 25 seconds without water spray), the foaming cycle is repeated for another 30 seconds. Remove it from the tub and place it in the beaker, remove the foam-filled box from the sink, and remove the contents of the box from the cotton cloth (100% cotton, Pour through a strainer covered with a sturdy cotton cloth (cut to 16 inches x 23 inches) to remove all foam and place it in the appropriate beaker for foam volume measurement, while pouring water from the strainer and its basin. Weigh and check the water flow rate. Carefully lift the cotton cloth out of the strainer and transfer the foam to the beaker containing the previously filled foam. Once all bubbles are transferred to the beaker, the bubble height in the beaker is measured and its volume measured. This volume is the instant bubble volume.

The foam weight is then measured and the weight and volume are used to calculate the density of the foam. The box is then returned to the sink and the steps listed above are repeated using the previously used article. The total foam volume created by foaming for 2 minutes is the foaming capacity of the article. To ensure consistency, at least two standard products are run at the beginning and end of each (daily) experimental group. Standard products are the articles of Comparative Examples A and B. Standard products typically produce an average of about 1250 ml of foam having a foam density of about 0.058 g / ml.

The article of the present invention preferably contains from about 500 mL to about 4000 mL, more preferably from about 750 mL to about 3000 mL, most preferably from about 1000 mL to about 2500 mL, within 2 minutes based on the foam forming ability test. Create bubbles.

Once the foaming capacity is determined, the foaming time can be determined. The entire volume of foam is transferred to a filter cloth covered with cotton cloth and placed in a stability filter in the sink (top opening: 11.5 "in diameter, bottom circular diameter: 4.5", depth 3.7 ", 3 mm apart by 1 inch, total number of holes: 120 uniformly distributed on the circular plane and 37 uniformly distributed on the bottom of the filter) The bubbled filter is placed under water flow (1.0 gpm at 104 ° F.) and the time is measured. When the bubble is completely gone, the time measurement stops immediately, the time required for the bubble to disappear is the bubble disappear time.

Loft-Soft Bee Methodology

The ropetness and softness of the substrate are related to each other. Softness has several independent contributing factors. One factor is the softness of the "pillowy" kind. That is, when a force is applied by hand or finger pressure, the substrate is easily compressed in the same way that the pillow is compressed under pressure and the part of the body resting on it is supported. This test measures the parameters related to Lofty using the following equipment:

1. Instron Model 1122 compression and tensile tester (or equivalent);

2. Instron serial number 445 (maximum scale 200 g) compressed load cell (or equivalent);

3. Flat top plate, attachable to load cell;

4. Flat bottom plate, located under the load cell;

5. 1.875 inch diameter perforator; And

6. Hammer.

The substrate sample is cut using a 1.875 inch diameter drill and hammer. If the drilling process inelastically compresses the edges of the disc, the edges are carefully inflated to restore the original dimensions. Place the top plate in position, calibrate the Instron load cell, and activate crimp mode at a descent rate of 0.50 inches / minute. Instron can be adjusted manually or by computer, as long as the final compression is above 30 g / in ² pressure, and collects data fast enough to measure height at various compression values during descent (using a computer is recommended). . The top plate is then moved down until it comes in contact with the bottom plate at the point where the height is set to zero. It is important that the top plate and the bottom plate are in parallel so that they are in contact at all points simultaneously.

Once the instrument is zeroed, the top plate is returned to the position above the bottom plate to allow enough space for the substrate sample disc to be inserted. The substrate disk is then placed in the center of the bottom plate. Then adjust the Instron so that each substrate sample is fully compressed once. After that, turn on the Instron and record the height and force of the top plate continuously. Once the crimping of the sample is complete, the crimping of the sample is repeated several times as necessary to obtain a reliable average. 5 gms / in ² and 30 gms / in compression value of ² in average height above the bottom plate equal to the thickness at each of 5 gms / in ² and 30 gms / in ^2. The loft-soft ratio is then calculated as the ratio of the thickness at 5 gms / in ² divided by the thickness at 30 gms / in ² .

Crepe Bee Method

The creping process produces a substrate having a pattern of peaks and valleys. The creping is bulk, soft, enhanced dirt removal capability, enhanced air and water delivery force required for foaming, compressive elasticity, and It can add value to the substrate by providing a visually good appearance. The substrates can be creped individually and combined with other substrates that are creped or uncreped; Multilayer articles can also be creped. This method can be used to define the amount of creping for individual substrates or final article. There are many different ways to measure the amount of creping. The purpose of this method is to define a bulky thick dimension that exhibits the lowest to lowest dimension of the substrate; And thin dimensions representing the "wall thickness" of the substrate.

The first layer preferably exhibits a crepe ratio of about 3 to about 45, more preferably the crepe ratio lower limit 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 crepe ratio is more preferably 20, more preferably 15 and most preferably about 12. These lower and upper limits can be combined to provide an optimum range.

First, the thickness of the substrate to be tested is measured at a crimp relaxation hysteresis value (CRHV) of 5 g / in ² according to the loft-soft method described above. Several representative pieces of the same substrate are cut to size in ² . The Flat End Knife Probe (thickness 0.02 inch × 7 mm wide) is then attached to an Instron Model 1122 compression and tensile tester (or equivalent) in a vertical position. The knife end face is defined with a rectangular dimension of 0.200 inches by 7 mm parallel to the bottom plate. Place and calibrate the Instron serial number 445 load cell with a maximum scale load setting of 100 gms. The Instron tester is run in crimp mode at a descent rate of 0.20 inches / minute. The instrument can be operated by computer or manually so that the final compressive force reaches a minimum of 25 g force, and the data is collected quickly enough (using a computer is recommended) to determine the height at various compaction values during the descent. The top plate is then moved down until the knife end is in contact with the bottom plate and the zero point height is set. The knife smooth end and the bottom plate must be in parallel, making contact at all points simultaneously. Return the knife probe to the position above the bottom plate so that there is enough space to insert the substrate. The substrate is then placed on the bottom plate so that the smooth end knife probe lower can be lowered for the longest time possible without contacting any part of the substrate. The Instron is then started to squeeze these grooves of the sample with a knife blade. The sample must be steered during the slow descent of the knife blade to ensure that the thinnest possible substrate dimensions are measured. This is the wall thickness. The Instron is then run until the force reaches about 50 g, while the height and force are continuously recorded, preferably by computer printing. Additional substrate samples are similarly tested for a reliable average. Record the average height above the bottom plate at the compression value of 10 g force. The crepe ratio is then determined by dividing the substrate thickness at 5 g / in ² measured by the loft-soft ratio method by the thickness measured at 10 g force with a smooth end knife probe.

Surface Saturation Ratio Methodology

Articles of the invention comprising a therapeutic benefit component have a therapeutic benefit component substantially on the surface of the substrate. The expression “substantially on the surface of the substrate” indicates that the surface saturation ratio is greater than about 1.25, preferably greater than about 1.5, more preferably greater than about 2.0, even more preferably greater than about 2.25, most preferably greater than 2.5. Means that. Surface saturation ratio is a measurement ratio of a benefit substance on the surface of a substrate. These measurements are obtained using an Attenuated Total Reflectance (ATR) FT-IR spectrometer well known to those skilled in the art of analytical chemistry.

Many existing methods of applying conditioning agents to substrates utilize processes and / or product rheology that are inadequate for the purposes of the present invention. As an example, the conditioning agent is applied to the entire substrate via a so-called "dip and nip" process, which is a process of soaking the substrate web into a fluid bath of conditioning agent and then pressing the substrate web through a metering roll. When applied, opportunities for effective direct delivery of the composition from the fabric to other surfaces during use are not met. In addition, many of the articles of the present invention effectively provide a full body benefit with sufficient load of conditioning agent on the substrate, which generally requires about 100% to 200% loading rate based on the dry substrate weight. Known personal care tools that utilize these high load levels essentially avoid the handling of aesthetic problems that can result from high loads by uniformly distributing the load throughout the substrate, including inside the substrate. Applicants are surprisingly improved by the compositions of the present invention, while a high load conditioning agent can be retained on the surface of the article and, therefore, the opportunity for direct delivery of the beneficial substance from the substrate to the treated surface can be advantageously met while in use. It has been found that it can convey aesthetic sense.

The procedure for obtaining the measurements is as follows.

Instrument setup

BioRad FTS-7 spectrometer manufactured by BioRad Labs of Digital Laboratory Division, Cambridge, MA, was used for the collection of infrared spectra. Typically, 100 scans were measured at a resolution of 4 cm ^-1 . Acquisition optics consisted of flat 60 degree ZnSe ATR crystals manufactured by Graseby Specac, Inc. (Fairfield, CT). Data was collected at 25 ° C., Galatic Industries Corp. Analysis was performed using Grams 386 software distributed by Sallem, NH. The crystals were cleansed with an appropriate solvent before the measurement. Samples were placed on ATR crystals and kept under a constant 4 kg weight.

Experiment method

(1) Measure the reference (background) spectrum of cleansed and air dried cells.

(2) First, the substrate to which the benefit substance is not applied is selected, and the selected substrate constitutes the outer surface of the article. The substrate is placed on top of the ATR crystal, the outer surface of the crystal. Place the substrate flat on the bench. Thereafter, 4 kg weight is applied on the substrate. The spectrum is then measured (typically 100 scans at 4 cm ^-1 resolution). Since the absorbance of the substrate alone is confirmed, the substrate acts as an internal standard. Identify the major substrate peaks and wavelength numbers.

(3) The above process is repeated for the description of the article to which the benefit ingredient is applied. Does not correspond to a substrate peak as previously observed; Or identify the peak height of the primary benefit material, which is the highest observed peaks that correspond to the previously observed substrate peaks but show a significant percentage increase in absorbance due to the presence of the conditioning agent. Record the number of wavelengths and the absorbance of the various benefit component peaks.

(4) From the spectrum determined in step 3, a substrate peak generated at the number of wavelengths determined in step 2 but not corresponding to any of the primary benefit peaks selected in step 3 is selected. The number of wavelengths selected and the absorbance from the absorption spectrum of step 3 are recorded.

(5) Calculate the ratio of the peak of each benefit substance determined in step 3 to the peak height of the substrate determined in step 4. The highest number of groups represents the surface saturation ratio of the article.

The following includes some examples:

Moisture Retention Methodology

As described above, the articles of the present invention are considered to be "substantially dry." As used herein, the phrase "substantially dry" indicates that articles of the invention are less than about 0.95 gms, preferably less than about 0.75 gms, more preferably less than about 0.5 gms, even more preferably less than about 0.25 gms, even more preferred. Preferably less than about 0.15 gms, and most preferably less than about 0.1 gms. The moisture retention is a measure of dry feeling that users perceive as opposed to feeling "wet" towels when touching the articles of the present invention.

In order to determine the moisture retention of articles based on articles of the invention and other disposable substrates, the following equipment and materials are needed.

White Bounty Paper Towel Procter & Gamble SKU37000 63037 Foundation Weight = 42.14gsm Scale Exactly 0.0g Lexan Large enough to fully cover a 0.5 "sample and weighs 1000g Weight 2000g weights or combinations equivalent to 2000g

Then, two paper towels are weighed separately and recorded. Place a piece of paper towel on a flat surface (eg bench). Place the sample article on the towel. Place another piece of paper towel on top of the sample item. The Lexan is then placed and the 2000 g weight (s) placed on the sandwiched sample article. Wait for 1 minute. After 1 minute, remove the weight (s) and Lexan. Weigh the paper towels above and below the sample and record the weight.

For both the top and bottom paper towels, the moisture retention is calculated by subtracting the initial paper towel weight from the final weight (after 1 minute). The weight difference obtained for the top and bottom paper towels is summed. Assuming that a large number of articles have been tested, the moisture retention is calculated by averaging the total weight differences.
