WEAR RESISTANT TOPICAL COMPOSITIONS HAVING IMPROVED FEEL

Abstract: The present invention relates to substantially uniform, discontinuous films of a topical product having a defined abrasion resistance, coverage value and particle spacing. The films are wear or transfer resistant and provide good skin coverage, while simultaneously providing improved skin appearance, e.g. good apparent coverage and a natural look. The films can be formed by methods which provide the defined particle coverage and spacing, including silk screening and the like and electrostatic spray techniques. The films are preferably formed by electrostatically spraying the composition onto the skin.

Description: WEAR RESISTANT TOPICAL COMPOSITIONS HAVING IMPROVED FEEL Field of the Invention The present invention relates to topical compositions which upon application to the skin form a durable, discontinuous film which is resistant to wear and transfer and which also exhibits improved skin feel and appearance. The films are characterized by an abrasion resistance value, a coverage value and an average particle spacing which reflect this desired combination of wear resistance, good feel and appearance. In a further embodiment, the films are characterized by a defined flexibility value. Background of the Invention A variety of topically-applied skin treatment products, including skin lotions, creams, cosmetic foundations and the like, are known. Such products are generally applied by massaging or rubbing into the skin with the fingers or sponge type applicator to provide essentially complete coverage of the skin with the product. Typically, about 80% or more of the skin surface is covered by the product, forming an essentially continuous film of product on the skin. While such continuous coverage can be beneficial, in certain applications it can result in undesirable effects. For example, while it is desirable to provide cosmetic foundations having good coverage properties, it has been difficult to achieve good coverage while maintaining a natural look and skin feel. This is a particular problem with wear or transfer resistant products. While such products may provide desirable properties such as resistance to transfer to objects such as linens, dishes and the like, this transfer resistance tends to come at the expense of skin feel. That is, long wear cosmetics tend to suffer from esthetic disadvantages such as perceived skin tightness, stiffness, tackiness and/or dryness. Other methods of applying topical products are also known, including air brush, aerosol spraying, non-aerosol pump spraying, and electrostatic spraying. For example, electrostatic spraying of skin treatment agents is disclosed in US Patent 5,494,674, issued to Barnett et al. on Feb. 27, 1996. Electrostatic spraying of topical materials has been proposed as a means for more efficient consumption and product activity, control over application, ease and cleanliness/hygiene of application, and even coverage. While a variety of topical compositions have been provided, there is an ongoing need to provide topical compositions which impart both good skin coverage and wear or transfer resistance, while at the same time providing a natural look and good skin feel. In view of these limitations, after much experimentation it has now been found that transfer or wear resistant topical compositions, particularly pigmented cosmetic foundations, which are applied so as to form a substantially uniform and discontinuous film having defined properties provide improved skin appearance and skin feel. More particularly, the films provide a natural look and reduced sensations of tightness, dryness, tackiness and/or stiffness. These properties of wear or transfer resistance, appearance and feel are defined by an abrasion value, coverage value and particle spacing according to the methods herein. The coverage value of the present films is significantly lower than products which are not applied in a discontinuous film, but rather for example applied using conventional methods of massaging or rubbing into the skin. Surprisingly, the preferred films nonetheless provide good coverage in terms of appearance, e.g., evening skin tone and masking local skin imperfections such as spots, blemishes, circles and the like. However, since the actual percent skin coverage is relatively low, the films look more natural. Summary of the Invention The present invention relates to substantially uniform, discontinuous films of a topical composition having both wear or transfer resistant properties and good skin coverage, along with natural appearance and good skin feel. The wear or transfer resistance is measured by an abrasion test resulting in an average resistance of less than about 6 mg, preferably less than about 3 mg, more preferably less than about 1 mg. Skin appearance and skin feel are measured by a coverage value which is less than about 80%, preferably less than about 70%, more preferably less than about 60%, and an average particle spacing of at least about 3 microns, more preferably at least about 7 microns, most preferably at least about 10 microns. Skin feel can be further characterized by a flexibility test resulting in an average percent weight loss of about 35 % or less, preferably about 30% or less, more preferably about 20% or less, even more preferably about 10% or less, most preferably about 5% or less. The films can be formed by any method which provides the defined coverage value and particle spacing, including silk screening and the like and electrostatic spray techniques. The films are preferably formed by electrostatically spraying the composition onto the skin. The topical compositions from which the films are formed comprise a (i) carrier which comprises one or more liquid diluents, (ii) one or more materials which provide wear or transfer resistance, and (iii) one or more paniculate materials dispersed in the composition. The liquid diluents may be volatile or nonvolatile, and polar or non-polar. The composition is preferably electrostatically sprayable, comprising at least one conductive material which is preferably a liquid, more preferably a volatile liquid. The electrostatically sprayable compositions may also comprise one or more insulating materials, at least one of which is preferably liquid and more preferably a volatile liquid. More preferably, the electrostatically sprayable composition comprises an emulsion wherein the insulating material and conductive material are in different phases, even more preferably wherein the insulating material is in the continuous, external phase and the conductive material is in the discontinuous, internal phase. In a preferred embodiment, the topical composition further comprises one or more materials selected from structuring or thickening agents, emulsifiers and co-solubilizers. The present invention can be used in a variety of topical applications where deposition of a wear or transfer resistant, discontinuous product film would be advantageous, and is particularly well suited to cosmetic foundation applications. For example, long wear or transfer resistant compositions of the invention may be designed and utilized to reduce potential for local irritation, to provide more uniform and/or natural-looking application of skin treatment agents or compositions, including pigmented products such as color cosmetics, and/or to improve the feel. Pigmented products provide sufficient coverage of imperfections, while providing a natural look. Better shade matching of skin and pigmented foundation compositions is also enabled, e.g., because the foundation integrates with the natural skin color, creating a composite shade. The present invention therefore enables broader useful shade palettes.

(I) Film Characteristics In additional to their compositional structure, films of the present invention are characterized by their physical characteristics of abrasion resistance, coverage value and average particle spacing. Films of the present invention exhibit a degree of transfer resistance or wear resistance which is directly proportional to the abrasion resistance of a film of the composition as measured by the test described below. This abrasion test predicts the ability of a topical product film to resist transfer or wear upon contact with objects. Such objects include clothing, handkerchiefs or tissues, napkins and implements such as cups, glasses and table wear. The average abrasion resistance of the present films by the abrasion test is less than about 6 mg, preferably less than about 3 mg, more preferably less than about 1 mg. The films are discontinuous, that is, they provide less than about 80% coverage of the substrate to which the topical composition is applied. The coverage is reflected by a coverage value. The films hereof have a coverage value of less than about 80%, more preferably less than about 70%, most preferably less than about 60%. The films hereof also have an average spacing between particles of at least about 3 microns, more preferably at least about 7 microns, most preferably at least about 10 microns. These properties are determined in accordance with the following methods: (A) Abrasion Test According to this method, a thin, uniform film of the topical product is tested in its ability to withstand force applied by the roller test method. Technical wear is measured by weight difference before and after testing. The equipment utilized is: BYK-Gardner Abrasion Tester (model AG 1800) Foam roller replacements, 4 inch (Ace Trimline #1018928) 1.0 mil (.001 in.) thin film applicator, e.g. a Bird Film Applicator #AR-5256 available from B YK Gardner, Inc., Silver Spring, MD Black/White hiding power chart (Leneta Card), e.g. Form 2A available from Leneta Corp., Mahwah, NJ The test procedure is as follows: 1 ) Mark a Leneta Card with a 5 cm X 5cm square area using a black marker to define a test area. Secure the Leneta Card to a drawdown plate or other smooth and flat apparatus to ensure the card is flat and will not shift. Wipe the card surface with a clean, lint free cloth to remove air from beneath the card and to help ensure even, uniform drawdowns. 2) Place the thin film applicator near the top of the Leneta Card and pour or spatula a l-2ml sample onto the card just in front of the applicator. 3) Using two hands, draw the sample down by pulling the applicator forward while applying slight downward pressure. The applicator should be pulled in single, smooth motion to the bottom of card. Wipe off any sample that falls outside of the marked test area to ensure that all samples have the approximately the same amount of starting product. This process should leave approximately 40 mg (+/- 2 mg) of the wet product in the test area. 4) Remove the card from the drawdown plate and dry overnight at room temperature (25°C). After a minimum of 12 hours, place the card in a 40°C oven for 1 hour to allow the sample to fully dry and stabilize. Remove the card from the oven, and allow it to sit for 30 minutes. 5) There should be an equal number of foam rollers to number of samples to be run. The rollers must be used only once, and may not be shared sample to sample. Weigh each roller on an analytical balance with a sensitivity of 0.1 mg (W 6) Place the Leneta card on the tray of the abrasion tester with the top of the card on the right side of the machine. The right side of the card should be placed evenly with the right side of the tray and taped in place. 7) Place a fresh Foam Roller Replacement on the roller arm of the BYK-Gardner Abrasion Tester (Roller Machine). 8) Set the number of cycles to 30 passes using the thumbwheel switches on the counter. Close the cover completely. 9) Press the POWER switch on (the red POWER switch will be illuminated). 10) To begin the abrasion testing sequence, depress the RUN switch. After 30 cycles are completed, the instrument will automatically shut off. The power light will remain illuminated. 11) Turn the power off and remove the sample from the tray. Remove the roller from the arm, and reweigh (W b ). Calculate the Abrasion Removal (AR) of each sample in terms of mg product removed . (AR=W b -W a ) Steps (1) through (12) are repeated three times for each composition formula tested. The average of the three AR values is determined; herein referred to as the Average Abrasion Removal; or AAR. Low numbers in the AAR values correspond to products having desirably high wear and transfer resistance. The AAR for preferred films of the present invention is about 6 mg or less, more preferably about 3mg or less, most preferably about lmg or less. (B) Particle Spacing and Coverage Value The properties of particle spacing and coverage value are determined in accordance with the following methods. The methods utilize computerized image analysis which measures the distribution of particle sizes, relative spacing and areas in a test film based on the areas of light colored particles on dark backgrounds (using a 0 : 255 gray scale). The test film is prepared by applying a composition onto a substrate in the manner desired for topical application and allowing it to dry. A microscope and camera are used to capture an image of the resulting film which is displayed on a computer monitor (framegrabber), and information from the image is inputted to a computer and analyzed utilizing imaging software. The methods involve the steps of: 1. Calibrating the camera brightness/contrast (black/white) to obtain the highest contrast between light and dark. 2. Calibrating the monitor pixels spatially to determine the length of each pixel to be measured. 3. Setting the threshold for the image being analyzed on a gray scale of 0-255. 4. Classifying a given pixel in the image as being substrate or test product film based on the threshold value. Points which have light intensity at or above the threshold are designated foreground (corresponding to test product film); points having a light intensity below the threshold are designated background (corresponding to substrate). 5. Constructing connected components for the foreground areas (computer-drawn lines around the common area designated as test product in step (4), hereinafter alternatively referred to as "particles"). 6. Determining the size of the connected components based on the number of pixels. In order to be included in the analyses, the perimeter of a particle must be at least 16 pixels. This method displays and determines the size for all particles found which meet this perimeter requirement. 7. At least 10 random representative sample images are acquired and analyzed for each test product. The measured distribution data can be displayed as a graph or can be written out to a spreadsheet, including histograms. Many computer programs for imaging analyses and calculations of the type described herein are commercially available, and can be tailored to perform the functions described herein by those having ordinary skill in the art without undue experimentation. Equipment/Settings The following equipment and corresponding settings are utilized. 1. Zeiss SV-11 stereomicroscope with a lx lens (S 1 ,0x) or the equivalent thereof - Magnification is 5.0 and the iris is completely open ("big dot"). This is a magnification of 5X. 2. Fostec 8375 (EJA) Ring Light (reflected light) or the equivalent thereof, mounted on the microscope lens. Set the ring light to maximum. 3. Computer with frame grabber board (e.g., an Occulus TCX board or the like) to digitize the analog signal of the camera, suitable imaging software (e.g., Optimas 5.21 or higher, commercially available from Media Cybernetics, L.P. of Silver Spring, MD) and suitable spreadsheet software (e.g., Excel 4.0), 2 monitors (one for operator-computer interface and one for showing a live video image of the microscope view, i.e., a framegrabber, having a resolution of 640 pixels wide and 480 pixels high). 4. Sony 3-C-CD Camera (or the equivalent thereof). The back of the control box has the following settings: Gamma - off; Linear Matrix - off ; computer cables are connected to RGB1 and Composite Sync, not RGB2. The front of the control box has the following settings: Color Temp. - 3200K; Shutter off; Gain 0; White/Black balance - auto; iris auto; Mode - camera; Detail - 12 o'clock position; Phase - 0 degrees not 180 degrees; SC-3 o'clock position; H-12 o'clock position. Balance the white light using the light source by pressing the button that says white. Balance the black, after pulling rod with black ball on microscope that deflects the light from raveling to the camera, by pressing the button that says black. Allow the light to warm up and stabilize for 15 minutes before setting the white balance or using the program. The settings for this camera are suitable for equivalent cameras which are also commercially available. Sample preparation Films of the product to be tested are prepared by uniformly applying the test product onto clear acetate sheets 19x17 cm in size in the desired manner of application, e.g., electrostatic spraying or passing through a mesh as described herein or other desired method of application. The product is allowed to dry under ambient conditions (21 C, 1 atm) for at least 15 minutes prior to image analysis. Electrostatically sprayable compositions such as described herein may be applied by spraying such that the spray is emitted from the spray device at a distance of 7 +/- 0.5 inches from the sheet and perpendicular to the sheet. The product is applied by making 10 complete passes over the length of the sheet at a rate of 1 foot/second and at a product flow rate of 9 ml/hour. Calibration The camera brightness/contrast is calibrated upon starting the application, and is recalibrated whenever the microscope lens or lighting is changed. Spatial calibration is also calibrated, however there is a default calibration that is valid when the microscope lens is l.Ox (Sl,0x) and the magnification is 5.0 (default calibration is 1 pixel = 2.681 microns). If any other lens or magnification is used, spatial calibration must be conducted. To perform brightness/contrast calibration, a black and white opacity card (e.g., from Leneta) is used as a standard and is placed under the microscope and positioned so that half the image in the camera monitor is white and the other half is black. The view is focused and the imaging software is run to automatically adjust the camera brightness and contrast. The standard should not be moved during adjustment. If necessary this step is repeated until successful calibration is indicated. To perform spatial calibration, a spatial calibration standard (a cm ruler or a millimeter graticule slide) is placed under the microscope and brought into focus. Calibration then involves constructing a line in the image, using the cursor, connecting the ends of the standard (about 1 mm long). The length of this line is automatically computed in microns and saved (this calibration may be saved as a default each time the application is used). Analysis The analysis is performed after calibration is completed. To perform the analysis, place the acetate sheet coated with the film to be tested on a dark background (e.g., a piece of black glass) under the microscope and focus. A live image acquisition mode is used such that the monitor displays live images. 10 random images are captured and analyzed in accordance with (A) above and the following. (i) Particle Spacing Analysis Spacing is calculated based on the distance of each foreground pixel of the input binary image with the distance to its nearest background pixel. The analysis involves the following steps: 1. Threshold the image to (127.5 : 255). 2. Invert the image. 3. Change the inverted image into a binary image. 4. For each foreground pixel in the binary image, calculate the digital distance to the nearest background pixel. 5. Create a 16 bit distance image for the values collected. 6. From the data create a histogram of the distance versus how many pixels are at that distance. 7. Calculate the mean of the histogram (the standard deviation may also be calculated). In this method, the mean is a half distance of the actual spacing between particles and is the relative spacing number reported as the average spacing between particles. (ii) Coverage Analysis The coverage analysis involves determining the pixel area of product film having a minimum gray value relative to the total pixel area in a given image. The analysis involves the following steps: 1. Convert the image into 8 bit gray. 2. Threshold the image to (140 : 255) in the gray scale. 3. Isolate all areas that have a threshold of 140 or above and outline these areas to form connected components (the outlined areas correspond to the product film and are also called foreground). 4. Calculate the numbers of pixels in the area labeled as product (designated as foreground area). 5. Calculate the total number of pixels in the image's total field of view (i.e., all of the pixels in the background and the foreground combined). This is designated the Total Area. 6. Use the following equation to calculate the percent area covered: (Foreground area/ Total area) x 100 = Percent area covered. The percent area covered is the coverage value. (iii) Optional Particle Size Analysis Preferred films may additionally be characterized by their particle size according to this method. Preferred films have an average particle size (diameter) of from about 0.5 to about 150 microns, more preferably from about 1 to about 100 microns, most preferably from about 5 to about 80 microns. Preferred standard deviations for the average particle size are or are less than 1.5 times, more preferably 1.0 times, most preferably 0.7 times, the average particle size. The threshold value is set to (140 : 255). The computer will determine the diameter of all of the pixels that it has designated as a particle in accordance with (A)(6) above. The computer calculates the average equivalent diameter of all the relevant particles: A relative diameter is created by taking the number of pixels that are in a given particle and extrapolating a circle and calculating the diameter of the circle. The average diameter is the average of all the diameters, which is the average particle size according to this method. The computer also calculates the standard deviation equivalent diameter of all the relevant particles (the standard deviation of all the equivalent diameters calculated above), which is the standard deviation for the average particle size according to this method. Films of the present invention that provide the abrasion resistance, coverage value and particle spacing comprise: a) from about 0% to about 90% of a liquid insulating material; b) from about 2% to about 90% of a conductive material; c) from about 0.1% to about 35% of a paniculate material which is insoluble and immiscible in the composition; and d) from about 0.1% to about 20% of a material for imparting wear or transfer resistance. In one embodiment, the films are further characterized by their flexibility according to the following test. (C) Flexibility Test Flexibility or the ability of the film to stretch and move with the skin is important towards providing improved long wear benefits of the film, particularly improved skin feel. Flexibility is measured by the following latex stretch test. This test predicts the ability of the film to resist flaking or peeling types of failure after application by movement during normal activities. The equipment utilized for the test is: 1. Ansell Edmont Industrial technicians unlined gloves (12" length, 17 mil) USDA Accepted #390, Size 9; 2. Disposable lip brush such as those available from La Femme Cosmetics, Inc. of Los Angeles, CA; 3. Analytical balance (0.1 mg measurement sensitivity limit); 4. Ruler; and 5. An apparatus as illustrated in Figure 1. This apparatus can be constructed from Lucite sheet and rod stock wherein posts 2a are approximately 6 inches apart. The test procedure is: (1) Cut a 1 inch wide band from the wrist area of the glove, avoiding the ribbing and thumb. (2) Mark off a 1 x 1 inch block in the center of the band, avoiding the embossed number. (3) Weigh and record the weight of the latex band; hereinafter referred to as W d . (4) Using a disposable lip brush, evenly apply 5.2 +/- 0.2 mg over the 1 x 1 inch area of the band as marked in step (2). (6) Immediately weigh and record the combined weight of the latex band and applied cosmetic (W e ) The wet film weight is calculated by subtracting the original weight of the latex band, W d from We (W d -W e = wet film weight) (7) Allow the sample on the latex band from step (6) to sit at ambient room conditions for 24 hours. (8) Weigh and record the combined weight of the latex band W d and the dried applied cosmetic film; hereinafter referred to as Wf. (9) Stretch the band just enough to slip over the posts (2a) of apparatus (1) of Figure 1. Gently manipulate the latex band on the posts so that the stretched film length is about 1.75 (+/- 0.125") inches. (10) Upon observing loosened film pieces on the latex band, remove the film pieces from the latex band by vigorously wiping a new disposable lip brush across the surface of the film for 50 passes. (11) Carefully remove the latex band from the posts (2a), allowing it to return to its approximate original shape. (12) Record the weight of the latex band (with the remaining cosmetic); herein referred to as W g . (13) Calculate the percent weight loss of the cosmetic film using the following equation: Percent Weight Loss (PWL) =(l-( [(G-D) ÷ (F-D)])) x 100 Steps (1) through (13) are repeated three times for each cosmetic formula tested. The average of the three PWL values is determined; herein referred to as the Average Percent Weight Loss; or APWL. Low APWL values correspond to flexible films having desirable adhesive and cohesive balance of the film. The APWL for preferred films of the present invention is about 35 % or less, more preferably about 30% or less, even more preferably about 20% or less, still more preferably about 10% or less, most preferably about 5% or less. (II) Compositions (A) Carrier Component The topical compositions from which the films are formed comprise (i) a carrier which comprises one or more liquid diluents, (ii) one or more materials for imparting wear or transfer resistance, and (iii) one or more particulate materials dispersed in the composition. Suitable liquid diluents may be volatile or nonvolatile, and polar or non- polar, and include the insulating and conductive materials described below. A variety of suitable carriers are known in the art of topical compositions, and are generally known to comprise one or more compatible diluents, extenders and the like. The type of carrier utilized in the present invention depends on the type of product desired. The topical compositions useful in the subject invention may be in a wide variety of product types including liquid or semi-liquid forms. These include, but are not limited to, lotions, creams, gels, sprays, ointments, pastes, and mousses. Compositions useful in the invention may for example comprise a solution of materials having the particulate material dispersed therein, or may comprise an emulsion having the particulate material dispersed therein. The selection of carrier components and amounts depends on the desired product type and is within the level of ordinary skill. The compositions will typically comprise from about 0.1% to about 35 % particulate, from about 0.1 % to about 20% of material for imparting wear or transfer resistance, and from about 5% to about 90% fluid carrier. The compositions generally comprise from about 5% to about 90% liquid diluent. The compositions will preferably have a viscosity of from about 10 to about 50,000 mPas at lOsec "1 (at 25 degree C, using 60mm parallel plate with 0.5 mm gap at rate of 10 sec "1 ). The composition is preferably electrostatically sprayable, comprising at least one conductive material which is preferably a liquid, more preferably a volatile liquid. The electrostatically sprayable compositions may also comprise one or more insulating materials, at least one of which is preferably liquid and more preferably a volatile liquid. More preferably, the electrostatically sprayable composition comprises an emulsion wherein the insulating material and conductive material are in different phases, even more preferably wherein the insulating material is in the continuous, external phase and the conductive material is in the discontinuous, internal phase. Preferred electrostatically sprayable, topical compositions comprise: a) from about 2% to about 90% of a conductive material; b) from about 0% to about 90% of a insulating material; c) from about 0.1% to about 35% of a particulate material which is insoluble and immiscible in the composition; and d) from about 0.1% to about 20% of a material for imparting wear or transfer resistance. In general, electrostatic spray techniques involve raising the composition to be sprayed to a high electric potential in a spray nozzle to cause the composition to atomize as a spray of electrically charged droplets. The electrically charged droplets seek the closest earthed object to discharge their electric charge, which can be arranged to be the desired spray target. In order to be electrostatically sprayable, a composition must have a resistivity which enables atomization as a spray of the charged droplets. In preferred compositions, the components of the composition are selected or adjusted such that the composition has a resistivity of from about 0.01 to about 5000 Mega-ohm-cm, more preferably from about 0.01 to about 2000 Mega-ohm-cm, most preferably from about 0.1 to about 500 Mega- ohm-cm. Resistivity is measured using standard, conventional apparatus and methods, generally at 25 degree C. Resistivity can be adjusted as necessary by varying the relative levels of insulating materials and conductive materials. In general, resistivity decreases with increasing percentage of conductive materials and decreasing percentage of insulating materials. The compositions intended for electrostatic spraying must also have a viscosity which permits electrostatically spraying. Materials of a wide range of viscosities may be suitable for use in the present invention, however the viscosity is preferably sufficiently high to minimize wicking of the composition droplets as they are applied. The tendency to wick depends on the surface tension of the composition and tends to increase with decreasing surface tension of the liquid diluent system. In compositions based on liquid diluents having a relatively low surface tension (i.e., which have a tendency to wet the substrate), it is generally desirable to utilize a viscosity increasing agent to minimize wicking such as the structuring agents or thickeners described herein. Preferably the viscosity is in the range of from about 0.1 to about 50,000 mPas, more preferably from about 0.5 to about 20,000 mPas, most preferably from about 5 to about 10,000 mPas (at 25 degree C, using 60mm parallel plate with 0.5 mm gap at rate of 10 sec "1 ). Conductive component Electrostatically sprayable compositions suitable for use herein contain one or more conductive components, more preferably volatile (i.e., having a measurable vapor pressure at 1 atm) and liquid. The conductive material ensures that the composition as a whole can, when in the presence of a non-uniform electric field, generate dielectrophoretic forces great enough to pull the composition toward the region of highest field intensity (hence creating an electrostatic spray). The conductive material preferably has a resistivity of less than 5000 Mega-ohm-cm, more preferably less than about 2000 Mega-ohm-cm, most preferably less than about 500 Mega-ohm-cm. This material preferably also has a relaxation time which is sufficiently long to enable a spray wherein all of the particles have a size of less than 300 microns according to standard light microscopy techniques. The conductive material preferably has a relaxation time of from about 1E-7 to 1 seconds, more preferably from about 1E-6 to 1E-2 seconds, most preferably from about 1E-5 to 1E-3 seconds. Suitable liquid conductive materials include polar solvents, polar aprotic solvents, glycols, polyols, and mixtures thereof. Preferred liquid conductive materials are selected from the group consisting of water, alcohols, glycols, polyols, ketones and mixtures thereof, more preferably alcohols, glycols, polyols (typically comprising about 16 or less carbon atoms) and mixtures thereof. More preferred conductive materials are propylene glycol, butylene glycol, dipropylene glycol, phenyl ethyl alcohol, ethanol, isopropyl alcohol, glycerin, 1,3-butanediol, 1,2-propane diol, isoprene glycol, water, acetone, or a mixture thereof. Particularly preferred conductive materials are propylene glycol, butylene glycol, ethanol, glycerin, water, or a mixture thereof. The conductive material is more preferably selected from propylene glycol, ethanol, and mixtures thereof, and is most preferably propylene glycol. The electrostatically sprayable compositions hereof are more preferably non- aqueous or contain only a small amount of water, e.g. less than about 10% by weight, preferably less than about 5% by weight, even more preferably less than about 1% by weight water. This is because, due to its short relaxation time (about 7E-6 seconds) and low resistivity, compositions containing large amounts of water generally create sprays which are difficult to control in terms of particle size and spacing when electrostatic means are used. The present compositions may further include non-liquid or non-volatile conductive materials. The total level of conductive materials in electrostatically sprayable compositions is typically from about 2% about 90%.

Insulating component Electrostatically sprayable compositions suitable for use herein may also contain one or more insulating components, more preferably volatile and liquid. By "insulating" it is meant that a material would not itself be suitable for electrostatic spraying (that is, it would not be able to cause sufficient alignment of the dipole molecules in the field to result in the subsequent, necessary net force), typically having a resistivity of greater than about 2000 Mega-ohm-cm, more typically greater than about 5000 Mega-ohm-cm. For electrostatically sprayable compositions, the total level of insulating materials is typically from about 0% to about 90%. Preferred insulating materials have a viscosity of about 10,000 mPas or less. Suitable insulating materials are selected from non-polar substances, e.g., oils and other hydrophobic materials. Preferred insulating materials are selected from the group consisting of volatile silicones, volatile hydrocarbons, and mixtures thereof. Suitable volatile silicones include cyclic polyalkylsiloxanes represented by the chemical formula [SiR2-O] n wherein R is an alkyl group (preferably R is methyl or ethyl, more preferably methyl) and n is an integer from about 3 to about 8, more preferably n is an integer from about 3 to about 7, and most preferably n is an integer from about 4 to about 6. When R is methyl, these materials are typically referred to as cyclomethicones. Commercially available cyclomethicones include Dow Corning® 244 fluid having a viscosity of 2.5 centistokes, and a boiling point of 172°C, which primarily contains the cyclomethicone tetramer (i.e. n=4), Dow Corning® 344 fluid having a viscosity of 2.5 centistokes and a boiling point of 178°C, which primarily contains the cyclomethicone pentamer (i.e. n=5), Dow Corning® 245 fluid having a viscosity of 4.2 centistokes and a boiling point of 205°C, which primarily contains a mixture of the cyclomethicone tetramer and pentamer (i.e. n=4 and 5), and Dow Coming® 345 fluid having a viscosity of 4.5 centistokes and a boiling point of 217°, which primarily contains a mixture of the cyclomethicone tetramer, pentamer, and hexamer (i.e. n=4, 5, and 6). Dow Corning® 244 fluid and Dow Corning® 344 fluid are preferred cyclomethicones. Other suitable volatile silicones are linear polydimethyl siloxanes having from about 3 to about 9 silicon atoms and the general formula (CH 3 ) 3 Si - O - [ - Si (CH 3 ) 2 - O - ] - n - Si (CH 3 ) 3 where n = 0-7.

For electrostatically sprayable compositions, the relative total levels of the insulating and conductive materials may vary, provided that sufficient conductive material is present such that the composition realizes the electrical potential during spraying. The compositions preferably comprise a total of from about 0% to about 90% more preferably from about 10% to about 70%, most preferably from about 20% to about 60%, of insulating material and from about 2% to about 90%, more preferably from about 5% to about 70%, most preferably from about 10% to about 60% of conductive material. In general, sprayability improves with the level of conductive material such that it will normally be advantageous to maximize the level of conductive materials. Preferred compositions comprise a weight ratio of insulating material to conductive material (disregarding any non-conductive particulate materials) of from about 10: 1 to about 1:12. For the preferred emulsion having an insulating external phase and conductive internal phase, the preferred weight ratio of insulating material to conductive material (disregarding any non-conductive particulate materials) is from about 0.2: 1 to about 8:1, more preferably about 1:1.

Exemplary emulsifiers include those disclosed in the C.T.F.A. Cosmetic Ingredient Handbook, 3rd Ed., Cosmetic and Fragrance Assn., Inc., Washington D.C. (1982) pp. 587-592; and Remington's Pharmaceutical Sciences, 15th Ed. 1975, pp. 335- 337; and McCutcheon's Volume 1, Emulsifiers & Detergents, 1994, North American Edition, pp. 236-239; all herein incorporated by reference. Particularly useful emulsifiers for the present compositions include polydiorganosiloxane-polyoxyalkylene copolymers.

Co-solubilizers. The compositions hereof may contain one or more co- solubilizers, e.g., to enhance the formation and stability of the composition. The co- solubilizer is especially useful to bridge compatibility of two materials which are normally incompatible, resulting in the creation of a single, stable phase. Co-solubilizers may therefore be particularly preferred in the single phase electrostatically sprayable compositions described herein. When used, compositions of the invention typically comprise from about 0.5% to about 10%, preferably from about 1% to about 5%, more preferably from about 1.5% to about 3% co-solubilizer. Suitable co-solubilizers are best chosen using a solubility parameter scale as is described in "Solubility: Effects in Product, Package, Penetration, and Preservation," by CD. Vaughan, Cosmetics and Toiletries, Vol. 103, Ocober 1988. Based on the solubility parameter of two incompatible materials, a third material with a solubility parameter in between that of the two incompatible materials may sometimes be found which is independently compatible with the two incompatible materials. When all three materials are then combined, they may exhibit the properties of a single stable phase, as could be measured, visually for example, via a light microscope. Co-solubilizers can be polar fluids, non-polar fluids, polar aprotic solvents, or amphiphilic materials and are chosen from these broad categories to fit the needs of the two incompatible materials to create a single phase. Particularly useful co-solubilizers include the polydiorganosiloxane-polyoxyalkylene copolymers described, including the polymers described in US patent 4,268,499, as well as the surfactants disclosed in U. S. Patent 5,143,722. Dimethicone copolyol is preferred.

In use, the control means is actuated to electrostatically spray the topical composition from the at least one delivery means directly onto the skin at an intended site. As will be appreciated by persons skilled in the art, particular constructional features and design and electrical and other operating parameters of such apparatuses may be selected or adjusted as necessary, in the context of the present invention, in accordance with the desired functioning characteristics, as for example dictated by the composition to be sprayed and/or the needs or wishes of a user. Features of the apparatus of the present invention which may be so selected and/or adjusted include for example: voltage generated by the high voltage generator and power source, electric field strength in or in the region of the product delivery means, flow rate of the product to be sprayed from the reservoir to and out of the delivery means, size and configuration of the delivery means itself and construction and properties of any product feed mechanism utilized between the reservoir and the output of the delivery means. The size and configuration of the one or more delivery means in the apparatus of the invention may be of any suitable form and again may be selected in association with other parameters to give an optimized functioning electrostatic spray delivery system. Commonly the or each delivery means will be in the form of a nozzle, preferably of insulating or semi-insulating material such as plastics or various polymers, as is well known in the art. In one preferred form of nozzle, a conduit for carrying the product to be sprayed terminates in an orifice at the tip of the nozzle, from which orifice the product is ejected for example initially as a ligament but in any event eventually dispersing as a spray of charged droplets. The orifice preferably has a diameter of not greater than about 800 microns (e.g., from 508 - 762 microns or 0.020"-0.030"). Even more preferably the orifice has a diameter of from about 500 to about 750 microns. The delivery means may advantageously include metering means to provide a dosing mechanism for delivering a predetermined fixed amount of material from the or each nozzle. Such an expedient may for example be useful in conjunction with a system having a controlled flow rate. In preferred embodiments of the apparatus of the invention, the or each delivery means is in communication, i.e. preferably fluid communication, with the reservoir or reservoirs (if for example more than one material or composition is to be desired to be sprayed from the same apparatus or even the same delivery means) by virtue of product feed means. In one preferred form, such feed means may comprise an insulator having a channel between the nozzle and the product reservoir, through which the product to be sprayed flows before reaching the point of high electric field strength where it is dispersed as a charged spray of droplets or particles. In another preferred form the feed means may comprise a hollow conduit through which the composition passes under the effect of capillary action. As is well known in the art, the apparatus according to the invention preferably includes a trigger (i.e. a manual control means) or alternatively an automatic control means to selectively apply the high voltage from the generator to the or each delivery means to electrostatically spray the composition onto the skin. Any other suitable control means however, e.g. which automatically control actuation of the system, may be used, as will be appreciated by persons skilled in the art. In preferred embodiments of the invention, voltages generated by the high voltage generator from the power source are in the range of from about 1 to about 26 kilovolts, more preferably from about 6 to about 20 kilovolts. The most suitable voltage for a given system may depend upon the product to be sprayed, as well as other parameters, all of which will generally be selected to give an overall optimized system. Voltage may be applied at constant positive or alternating polarity, however positive polarity is preferred. Electric field strengths which are responsible for the spraying action of the electrostatic apparatus will be largely dependent upon the voltage applied. However, field strengths may be controlled or adjusted if necessary, for example by changes in nozzle configuration or geometry and/or the use of field intensifying electrodes, which are well known in the art cited above. The particle size, particle spacing and coverage values of the present films are influenced by the product spray flow rate, the rate of product application to the skin, and the amount of product applied to the skin. In general, particle size increases with increasing resistivity, decreasing voltage, and increasing flow rate, particle spacing increases with increasing voltage and decreasing deposition amount, and coverage value increases with increasing flow rate and increasing deposition amount. Optimum flow rates of material to be sprayed will generally depend upon the composition of the product itself, and may be selected appropriately on that basis preferably so as to avoid sensory negatives. Also, as already mentioned with respect to viscosity of the sprayable material, a suitable flow rate may be selected depending upon the particular delivery regime and/or habit or needs of a user. Generally it will be desired to utilize lower flow rates with concentrated materials in order to better control the deposition of the composition. By way of example, preferred flow rates of compositions for delivery in accordance with embodiments of the invention are in the range of from about 0.036 to about 1800 ml/hr (0.00001 to about 0.5 ml/sec), more preferably from about 0.1 to about 360 ml/hr (0.0001 to about 0.1 ml/sec), even more preferably from about 0.1 to 100 ml/hr, most preferably from about 1 to about 30 ml/hr per the delivery means. Particularly preferred applications utilize a higher speed flow rate of from about 4 to about 18 ml/hr (preferably about 9 ml/hr), and a lower speed flow rate of from about 2.4 to about 10.8 ml/hr (preferably about 7.2 ml/hr), where the low speed is about 0.2 to 0.8 times the high speed. In general, as the flow rate increases it will be desired to utilize a higher voltage in order to provide optimal sprayability and small sprayed particle sizes. In a preferred embodiment, the composition is sprayed at a flow rate of from about 0.1 to about 100 ml/hr, a voltage of from about lkV to about 26 kV (preferably about lkV to about 20kV), and an application rate of from about 0.01 mg composition cm 2 of skin to about 12 mg composition /cm 2 of skin. Relatively high solids compositions such as foundations are typically applied at a rate of about 1 mg/ cm skin; relatively low solids compositions such as skin lotions are typically applied at a rate of about 5 to 6 mg/ cm 2 skin. Relatively low solids compositions such as skin lotions are typically delivered at a flow rate of from about 50 to about 60 ml/hr. Relatively high solids compositions such as foundations are preferably electrostatically sprayed at said application rate, at a flow rate of from about 1 to about 30 ml/hr and a voltage of from about 6kV to about 20kV. A voltage range of from about 3kV to about 20 kV is preferred. Total product application amounts, in terms of amount of product sprayed per cm 2 skin, should be less than about 6 mg/cm 2 skin. An exemplary application amount is about 0.8 mg/cm , which tends to provide about a 30-40% coverage value. The product is typically applied at a rate of 0.005 sec/cm skin area to 6 sec/cm 9 9 skin area, more preferably rate of 0.01 sec/cm skin area to 3 sec/cm skin area, most 9 preferably rate of 0.05 sec/cm skin area to 2 sec/cm skin area. (B) Preferred usage instructions for electrostatic application Electrostatically sprayable compositions may be applied by a second party (including robotic means) or the end-user of the composition. The present invention also relates to instructions for using an electrostatic spray device to apply topical compositions to the face, especially foundation compositions, and especially second-party and self- application techniques, context, and methods of training self-application. a) application techniques It has been found that improved results are achieved by observing certain directions relating to distance of the device (particularly the nozzle) from the target application area (the face), the rate of application of product to the skin (including flow rate and device speed settings), and motion of the device during application (including the direction and character of the motion). In use, the device is held or otherwise positioned so as to efficiently deliver the spray to the target facial area and to avoid obstruction of the spray. In general, the device is held or positioned sufficiently distant from the target such that the spray pattern spreads sufficiently and does not tend to form lines or other undesirable concentrated effects on the target substrate, and close enough such that the spray adequately grounds to the target so as to deliver optimum coverage and even-ness of laydown. Typically, the device is held or positioned such that the nozzle is from about 3- 4 inches (9-13 cm) from the target facial area. During self-application, it is best to keep one or both eyes open when applying to areas of the face below the nose, and closed when applying to areas of the face above the nose. When self-applying while the eyes are closed, it can be helpful to appropriately judge the distance with which to hold the device from the face, by first stretching the arm all the way out straight (until the feel of the spray mist on the face can no longer be felt clearly) and then bending the elbow to bring the device closer, slowly, until the spray mist is first clearly felt. This typically leads to ensuring that the device stays about 3-4 inches from the applier's face. For improved even-ness of coverage, the device should be kept moving during application, preferably at a steady pace with a sweeping motion, without stopping in place while the device is operating. In general, the preferred pace is such that in one second one can usually transverse the forehead, or make two passes over a single cheek, depending on the facial size. The swath areas may be partially overlapped, such as occurs with a Zamboni smoothing ice. In a typical 60-90 second application, each facial area is typically passed over 2-8 times. In a preferred technique, the composition is applied following the contours of the face and in four sections. First, smooth horizontal strokes are made across the forehead. Product is then applied to each side of the face utilizing back and forth sweeping, semicircular motions following the natural contours of the cheekbone working down to the chin from the side of the face to the center of the face. While applying to the cheeks, it is important to avoid the fourth region, the nose, which is preferably sprayed last since its relative height tends to preferably attract spray. The nose is then sprayed, if needed, along with the area above the upper lip. Where the wearer has visible facial hair, it may be preferred to tilt the nozzle slightly downward to minimize accentuating the visibility of the hair. Also, when first self-applying it is preferred to begin with the jaw line and work "up" the face until one becomes more comfortable with the application process. This allows the wearer to keep her eyes open initially and see where the spray is going on the face, and helps for judging how far away from the face she may be with the device. Improved results have also been found where the applicant utilizes two or more speeds for applying the product. The preferred use is typically to use a faster speed (higher flow rate) for all-over-face coverage and a slower speed for spot coverage. Preferred is a higher speed flow rate of from about 4 to about 18 ml/hr (preferably about 9 ml/hr), and a lower speed flow rate of from about 2.4 to about 10.8 ml/hr (preferably about 7.2 ml/hr), where the low speed is about 0.2 to 0.8 times the high speed The slow speed allows a more controlled build up of coverage in a specified area without unintentional overapplication. In general, the application process is designed so as to avoid overapplication, resulting in an unnatural look and/or uneven application, but to provide sufficient coverage. It can be helpful for a second party to first view the user with their typical facial makeup in order to identify likely coverage objectives. It is also helpful to utilize a stepwise application, involving at least one sequence of overall application and optionally spot coverage, so that the applicant or user can titrate to the desired appearance. A typical application process involves the following steps: 1) Apply all over the face using a relatively fast speed/flow rate designed to apply product at a rate of about 9 milliliters/hour; 2) judge whether or not more coverage is needed, and if so where and how much more; 3a) If more product is desired in "spot" areas, e.g., age spots, acne, red areas, dark areas, apply additional spray to the specific areas defined using a slow speed designed to apply about 5-7 milliliters/hour; 3b) If more product is desired "all-over", repeat step (1); 4) Iterate Steps 2 and 3 until the desired coverage is obtained. The overall time for application tends to be from about 0.5 to 3 minutes, b) context When instructing someone to apply product either to themselves or others, it has been found that the context with which the first application or demonstration is made is very important to help the end-user feel comfortable and positive about the application experience. The context is preferably designed to provide the user with visible and tactile expectations. It preferably includes the steps of reviewing safety, explaining how the spray works, and demonstrating how the spray works. More particularly, the safety of the composition, device and method is reviewed, typically including a recommendation to keep eyes closed when spraying above the nostrils as an added safety level. Any eye, inhalation, grounding/electrical safety or other concerns which the user may have are addressed. How the spray works is generally explained, for example, by explaining that the product is a fine mist of product droplets that are charged so that they stay separated during application and are uniquely attracted to the face versus non-target areas such as the hair, clothing, etc., yet needs no blending. Demonstrating how the spray works preferably includes showing how to hold the device (e.g., by resting it between the thumb and fore finger), and how to activate the device (e.g., by pressing the on/off button with your fore-finger, preferably instructing to keep fingers away from the nozzle). A useful demonstration before actual use involves providing a visible expectation (i.e., how the product comes out of the device), e.g., by spraying on a piece of paper, paper towel, non-target skin (e.g, hand or arm) or the like, and providing a tactile expectation, e.g., by spraying on non-target skin to show how the spray feels on the skin. The user should understand that the product is emitted as a fine, uniform spray or mist that needs no blending into the skin, which is very light in feel. The user should also preferably understand that the mist generally forms a circular, versus linear (jets) pattern and that the swath diameter is proportional to the distance of the device from the face. Other means may be provided to enhance the user's experience, e.g., music or other audio effects, flowers, aromatherapy, massage, or other known means of promoting relaxation. c) self-application training Where the user intends to self-apply the product, the learning curve for self- applying the composition is also important to user satisfaction. Preferred training involves at least a step of joint application by the user and a second party. More preferred training methods allow the user to gradually become familiar with the techniques, and involve a sequence of steps comprising application by a second party, joint application by the user and a second party, and full application by the user with optional assistance of a second party or instructional materials. The steps are preferably performed on different days, more preferably on consecutive days. However, the steps may be performed on the same day and optionally immediately following each other if it is practical and provided that cleansing of the user's skin between steps does not cause negative effects. One preferred method of training is a 3-5 day training period during which the user gradually becomes comfortable with self-application: (1) On the first day, a second party applies the product to the end-user. (2) On the second day, the second party applies product to half the end-user's face and then the end-user completes the application with personalized guidance from the second party and/or instmctional aids such as a usage pamphlet and/or a video of others self-applying the product. The second party or instmctional aid preferably reminds the end user of the proper device distance, speed, the desirability of keeping the eyes closed as described above, and other helpful suggestions such as described above, e.g., such as beginning with the jaw line and working "up" the face until becoming more comfortable with the application process. (3) On the third day, the end-user applies full face product with optional guidance from the second party and/or instructional materials. (4) On optional fourth and fifth days, the third day procedure is repeated. When it is desirable to demonstrate self-application with a single demonstration, the preferred method is to follow the above instructions for the second day. The self- application learning curve preferably involves three elements of expectation or context, technique or application, and confidence. Expectation/context involves addressing any safety concerns and describing the product which comes out of the device. Technique/application involves application techniques, including how to hold/handle the device and instructions regarding proper distance from the face, amount of product to apply, how long to apply, hand motion, and application speeds. Confidence involves allowing the user to practice applying the product, optionally with assistance from a second party or other instmctional aids. Preferred aspects of these elements is as described herein above. (C) Other topical application methods The topical compositions can alternatively be applied to the skin to form the discontinuous films by silk screen techniques or the like, and additionally by using application techniques which provide product deposition via the use of normal forces (i.e., forces perpendicular to skin surface). In the first method, a piece of plastic, metal, cloth or other mesh (preferably conformable to facial contours), with evenly spaced holes/pores of about 150 microns or less in diameter is placed against the skin. Then topical composition, e.g., a pigmented foundation, is pressed through the holes in the mesh to deposit the same pattern of droplets on the skin which exists in the pores of the mesh. One convenient way to press the fluid through the mesh is to first absorb it into a sponge, cloth or other absorbent material and then to press the soaked sponge or other material against the mesh. Another means of accomplishing this is to spread or draw the fluid across the mesh with a stiff- edged product such as a rubber squeegee, much like spackling a wall. After the product is pressed through the mesh, the mesh is removed, and cleaned if desired for re-use. The mesh is then moved to any bordering, uncovered areas and the process is repeated as many times as necessary to complete application of the target area. Once the fluid on the skin has dried, if applicable, the process may be repeated by placing the mesh back over the areas where product is already deposited, and orienting the mesh at a different angle to minimize the potential for overlapping droplets. This re-application process will allow for tighter particle spacing than inherently exists in the mesh, if desired. Any type mesh which allows for a deposition with the desirable size and spacing pattern described herein may be used. Examples of such materials include microaperatured formed films as are described in US Patent 4,342,314, issued to Radel et al. on August 3, 1982 and US Patent 4,629,643 issued to Curro et al. on December 16, 1986, both of which are herein incorporated by reference in their entirety. As is described in these references, suitable materials for these formed films are preferably polyolefins, e.g., polyester. Preferable mesh hole size and spacing is equivalent to the desired end discontinuous film particle size and spacing. Alternatively, the discontinuous deposition pattern is achieved without the use of a mesh or screen, but rather is accomplished through the use of a porous material with pores which are less than about 150 microns in diameter. The porous structure may comprise open cells, closed cells, or some combination thereof. The term "cells", as used herein, refers to the 3-dimensional voids present in the material which may, or may not have interstitial openings which would connect the voids to one another. In one embodiment, the fluid topical skin product is absorbed into the porous material and then "blotted" onto the skin using forces perpendicular to the skin (as opposed to tangential, or shearing forces). This application technique uses the pore size and pore spacing of the material to create the discontinuous deposition pattern. Such porous materials can be created by techniques which include, but are not limited to: 1) seeding mechanisms in which the pores are created by incorporating a physical material which is later extracted, destroyed, removed, or decays after the structure is formed, examples of such materials include elastomeric rubber structures manufactured by the Porelon and MicroFoam Companies such as Porlon and Microfoam brand materials which are described in US patents 3,971,315 and 4,824,621, both of which are herein incorporated by reference in their entirety; 2) aerating (i.e., incorporating air or inert gases into) polymeric materials via mechanical shearing, high pressure (e.g., forced air), or the like, examples include foams of synthetic latex nitriles produced Latex Foam Products, Inc. (LFP) such as "NBR", "SBR", or "SK" type materials; 3) using emulsion chemistry and processing techniques to control the pore size and density - examples of such materials include polyurethane foams produced by the Lendell corporation, or flexible microcellular foams such as those cited in US patent numbers 5,260,345 and 4,522,953, both of which are herein incorporated by reference in their entirety. 4) sintering powder particulates of various sizes to create the desired pore size and density - examples of such materials which utilize particulates of high density polyethylene, polypropylene, or nylon and are produced by the Porex Technologies Corporation (e.g. Porex X4900 and X4800 series in coarse sheets or custom-molded parts) . In another variation on the use of porous materials to create a discontinuous pattern, a continuous or discontinuous film of fluid is applied to the skin and the porous material (as described above) is subsequently blotted onto the continuous film to remove fluid from the skin surface by absorbing the fluid into the pores of the material. The discontinuous pattern, in this case, is formed by and corresponds to the stmctural pattern of the polymeric material which separates the pores. In this example, the spacing of polymeric material which separates the pores should be less than 150 microns in effective diameter. The phrase "effective diameter", as used herein, refers to the diameter of a circle with an area equal to the area of the irregularly shaped region of interest. In yet another execution, the discontinuous pattern is created by blotting non- porous materials with a relief texture in which the raised areas of the texture do not exceed 150 microns in effective diameter. In this execution the nonporous, textured material is blotted into a fluid reservoir (much like an ink pad), imparting the fluid product onto the raised textured areas of the non-porous substrate. The substrate is then blotted onto the skin (using forces normal to the skin) and the raised textured pattern of the nonporous material is transferred to the skin surface. In still another execution, the discontinuous pattern is created by blotting nonporous materials with a relief texture where the reliefed areas of the texture do not exceed 150 microns in effective diameter. The phrase relief texture or reliefed areas, as used herein, refers to the depressed areas of the textured surface or textures formed by such depressed areas or regions. In this execution the nonporous, textured material is blotted into a fluid reservoir, imparting the fluid product onto all surfaces of the substrate (both raised and depressed). The fluid product on the raised areas is then removed through a secondary process such wiping, absorbing, evaporating, or the like. The substrate is then blotted onto the skin (using forces normal to the skin) and the depressed textured pattern of the nonporous material is transferred to the skin surface.
