## Background
BACKGROUND OF THE INVENTION
Topical formulations for application to the skin take a variety of forms, ranging from dry powders, such as talc and corn starch, to liquids, such as lotions or creams, to solids or semi-solids, such as antiperspirants. Each of these forms provides certain advantages to the users which may determine the selection of the products incorporating the formulations.
Powder formulation based products typically provide a dry light feel when applied to the skin. In addition, the powder formulation may absorb skin surface moisture and/or oils and other bodily fluids, as well as deliver actives or agents to provide moisturization, odor control, lubrication, antimicrobial, and anti-irritant properties, to name a few. Typically, powder formulations comprise talc and/or corn starch alone or in combination with additional ingredients, such as fragrance, dimethicone, esters, zinc oxide, titanium dioxide, iron oxides, anti-caking agent, antioxidants, ultraviolet absorbents, etc., to provide actual or perceived benefits to the skin.
The powder formulation based products are typically applied to the skin in the form of a dusting powder or inside of an absorbent article as a dry powder form. Because these powder formulations are light, loose particles, relatively speaking, and have a relatively small particle size, application of the powder formulation may be difficult to control. Even with careful application, the powder formulations tend to form a dust cloud, causing deposits of the powder formulations over a larger area than the intended application target. Additionally, this dust cloud may cause an inhalation or aspiration health hazard, especially to young children and respiratory compromised individuals, such as those with asthma or chronic pulmonary diseases, leading to serious health situations or even death. Use of powder formulation based products by such individuals is strongly discouraged.
Cream and lotion formulation based products typically provide a smooth comfortable application as well as leaving the skin feeling moisturized or otherwise improved. While easier to use and control application of than powder formulations, the cream and lotion formulation based products may leave a wet feeling and/or greasy residue feeling on the skin or may not work well with a variety of skin types, such as oily skin.
In order to overcome the problems associated with the use of powder formulations and cream or lotion formulations, many formulators have developed liquid powder formulations that may be applied to the skin in the form a liquid, spray, and/or roll-on. However, some of the liquid powder formulations tend to dry slowly, leave a sticky or gummy feeling on the skin, during and/or after application of the formulations, or may not contain adequate amounts of powder to provide a powdery dry feeling on the skin. To reduce the transformation time of the liquid powder formulation from a liquid phase to a powder phase, the liquid powder formulations incorporate a volatile carrier into which the powder is suspended, such as an alcohol or volatile silicones or hydrocarbons. However, such volatile carriers may have a negative impact on skin health, such as dissolving or removing the natural lipid barrier of the skin, especially on compromised skin, such as chapped and chaffed skin or skin exhibiting diaper rash or dermatitis, rashes, hydration dermatitis, and other skin conditions.
Fast drying stable liquid powder formulations are needed to provide skin protection, reduced skin surface wetness and/or oiliness, lubrication and a dry powdery feel and/or appearance on the skin after application as well as providing a visual cue of skin dryness.
Accordingly, one aspect of the present invention is to provide a stable fast drying aqueous, non-alcoholic liquid powder formulation.
Another aspect of the present invention is to provide an aqueous, non-alcoholic skin protectant liquid powder formulation.
Another aspect of the present invention is to provide an aqueous, non-alcoholic liquid powder formulation that provides reduced skin surface wetness and/or oiliness after application after application of the formulation.
Still another aspect of the present invention is to provide an aqueous, non-alcoholic liquid powder formulation that provides a dry powdery feel and/or appearance on the skin after application of the formulation.
Still another aspect of the present invention is to provide an aqueous, non-alcoholic liquid powder formulation that provides a visual cue of skin dryness.
Still another aspect of the present invention is the application of a powder, delivered as an aqueous, non-alcoholic liquid, in a controlled manner, to provide skin protection, lubrication, a dry look, and a powdery skin feel.
These and other aspects of the present invention will become more readily apparent from consideration of the following summary and detailed description below.

The co-emulsifier may have a hydrophilic/lipophilic balance value ranging from about 4 to about 14, more specifically ranging from about 6 to about 12, and most specifically ranging from about 8 to about 11. The HLB is a numeric rating system for the combined hydrophilic and lipophilic characteristics of an amphiphilic molecule that contains both hydrophilic and lipophilic moieties, and thus is a measure of the emulsifying efficiency of an emulsifier. The HLB is related to the polarity of the molecule, the least hydrophilic emulsifiers having low HLB values, and increasing number correspond to increasing hydrophilic characteristics of emulsifiers. The specific HLB value that may be applied in the present invention is dependent on the hydrophobic material or skin health active being emulsified into the liquid powder formulation of the present invention.
The assignment of numerical values for HLB based upon chemical groupings in a molecule is given in “Physical Chemistry of Surfactants,” 2nd Ed. by A. W. Adamson (Interscience Publishers, New York 1967), pp. 520-522. A definition of HLB is also provided in Volume 1 of the Surfactants Science Series, Nonionic Surfactants, Chapter 18 by M. J. Schnick (M. Dekker Inc., New York 1967).

The powders may be presented in the form of microcapsules, and the like.
The powders that may be used in the present invention are not restricted by shape. They may be spherical, acicular, plate-like, tabular, or amorphous in structure. Typically, powders comprising particles having plate-like structures are used. The powders may be porous or non-porous. The particle size of the particles of the powders that may be used in the present invention may be about 70 microns or less, more specifically about 50 microns or less, and more specifically about 20 microns or less in diameter. The particles of the powder may range in mean particle size from about 0.9 microns to about 70 microns, more specifically from about 1 microns to about 50 microns, and most specifically from about 10 microns to about 30 microns.
Selection of the powder may determine the optical properties of the surface of the skin treated by the liquid powder formulation. The visual perception of the skin surface after the application of the liquid powder formulation may be altered by the selection of a powder having the appropriate size and shape of the particles to provide the desired optical properties to be realized on the surface of the skin treated with the liquid powder formulation. The particles of powder having irregular shapes may provide an optical perception of dryness of the surface of skin after an application of a liquid powder formulation comprising such particles. Mixing powders comprising particles of different refractive indices may further alter the optical perception of the treated skin surface.
Table 1 provides refractive indexes of powders that may be used in the present invention. The refractive index for a given powder is the ratio of the velocity of light in a vacuum to its velocity within the powder. It is also the ratio of the sine of the angle of incidence to the sine of the angle of refraction. The light that is not refracted into the given powder will either be absorbed by the powder or reflected off the surface of the powder. Using particles having a higher refractive index than the refractive index of the skin to be treated may result in more refracted light, less reflected light, and a better perception of skin dryness.
Altering the reflection of light from the surface of the skin may be accomplished by the selection of the powder incorporated into the liquid powder formulation. Particles of powder having irregular shapes typically scatter larger amounts and reflect smaller amount of the incident light than regular shaped particles of powder, such as spherical shaped particles. The reaction of the irregularly shaped particles of powder to incident light translates into a less shiny, more matte appearing surface of the skin treated with the powder.
Particles with irregular shapes would be preferred over spherical particles for delivering visual dryness perception. Irregular particles would scatter larger amounts and reflect smaller amounts of the incident light which translates into perception of less shiny and more matte surface for the human eye. In some embodiments of the present invention, the size of the particles would be small enough to avoid the gritty feel of individual particles. Particles below 50 microns, and more typically below 20 microns, are usually too small to be perceived as gritty.

The refractive index of the surface of skin is about n=1.47 and about n=1.40 in the stratum corneum and about n=1.39 at the dermis. (See W. Knaak, S. Bonev, and A. Knuttl, New Method for Evaluation of In Vivo Scattering and Refractive Index Properties Obtained with Optical Coherence Tomography, Journal of Biomedical Optics, Vol. 9(20, pp. 265-273 (2004). The higher the moisture content of the skin or its components, the refractive index values decrease.
By altering the size and shape of the particles of the powder, the skin feel provided by the liquid powder formulation may be devised to provide the desired sensory queue for dryness, skin tone, skin smoothness, and the like.
The surface of skin may appear wet when it is oily. The use of oil absorbing powders may be used in the present invention to remove excess oil and/or moisture from the skin surface and, thereby rendering a healthier and drier appearance of the skin surface. Microspheres and/or ellipsoids have been found to provide good skin appearance as well as skin feel due to efficient moisture and/or oil absorption.
Microspheres and/or ellipsoids are capable reducing the shiny look of moisture and/or oil due to their light scattering properties as well as absorption properties. For tactile perception, microspheres and/or ellipsoids may act as a barrier between the fingers and the oily and/or moist surface of the skin. Microspheres and/or ellipsoids may be capable of absorbing up to seven times their weight in moisture and/or oil due to their porous surface and accessible inner void.
The microspheres and/or ellipsoids may be preloaded with a volatile material, such as water, cyclomethicone, volatile hydrocarbons, and the like, so that the volatile material evaporates when applied on the surface of the skin, leaving the microspheres and/or ellipsoids empty and ready to absorb skin surface moisture and/or oils.
The microspheres and ellipsoids that may be used in the present invention include, but are not limited to: ZELEC Sil (commercially available from Du Pont, located at 1007 Market Street, Wilmington, Del., 19898); MSS-500, MSS-500/3, MSS-500H, MSS-500/3H and MSS-500/3H4, MSS-500N, and MSS-500/3N (commercially available from Kobo Products Inc., located at 690 Montrose Avenue, South Plainfield, N.J., 07080); Spheron L1500 and Spheron P1500 (commercially available from Presperse Inc., located at 635 Pierce Street, Somerset, N.J., 08873); Microsponges and Polytrap (commercially available from Cardinal Health, located at 7000 Cardinal Place, Dublin, Ohio, 43017); Aerosil (commercially available from Degussa, located at 379 Interpace Parkway, Parsippany, N.J., 07054); Cab-O-Sil (commercially available from Cabot Corporation, located at 700 E. U.S. Highway 36, Tuscola, Ill., 61953). Starches and modified starches may also be used to absorb moisture and/or oils from the surface of the skin and/or mitigate greasiness of the aqueous, non-alcoholic liquid powder formulations. Examples include tapioca starch, aluminum starch octenylsuccinate, and modified corn starch (commercially available from National Starch and Chemical Company, located at 10 Finderne Avenue, Bridgewater, N.J., 08807). The same techniques may be used when the source of the oily perception is not skin oils but rather an oily formulation that is applied directly on the skin or indirectly through transfer from articles that contact the surface of the skin (e.g. absorbent articles).
Powdered microcapsules may be used in aqueous, non-alcoholic liquid powder formulation of the present invention to deliver a variety of additional ingredients and/or benefits, such as skin health benefits. The additional ingredients, such as skin health agents, for example, may be encapsulated in a number of shell materials including but not limited to liposomes, nanosomes, nanoparticles, collagen, gelatin, dextrin, melamine resin, silicone resin, and starch. The advantages of having the additional ingredients encapsulated are many and well know in the art but the major advantages are protecting the active ingredient from exposure to harsh environmental conditions (oxidation), separating incompatible ingredients, and most advantageously controlling the release of the additional ingredients during or after the application of the aqueous, non-alcoholic liquid powder formulation. Controlled release may be triggered release, sustained release, or a combination, where the additional ingredient is released form the shell material or the entrapment material by a number of mechanisms including, but not limited to pressure, pH, UV light, capillary forces, and wetting with water. The particle size of microencapsulated materials and the polymeric entrapment materials typically have a size from about 0.1 micrometers to about 40 micrometers, preferably from about 0.3 micrometers to about 20 micrometers, more preferably from about 0.5 micrometers to about 15 micrometers.
The amount of the powder that may be incorporated into the aqueous, non-alcoholic liquid powder formulation may range from about 25% to about 60% by weight of the formulation, more specifically from about 30% to about 50% by weight of the formulation, and most specifically from about 35% to about 40% by weight of the formulation.
Neutralizing Base
The pH of the aqueous, non-alcoholic liquid powder formulation may be adjusted by the introduction of a neutralizing base. As stated above, the pH of the aqueous, non-alcoholic liquid powder formulation may range between about 4 to about 8.
Neutralizing bases that may be used in the present invention include, but are not limited to: triethanolamine; sodium hydroxide; ammonium hydroxide; sodium borate; sodium citrate; aminomethylpropanol (AMP); mixtures thereof; and, the like.
Water
The amount of water that may be incorporated into the aqueous, non-alcoholic liquid powder formulation may range from about 14% to about 75% by weight of the formulation, more specifically from about 20% to about 75%, more specifically from about 40% to about 65% by weight of the formulation, and most specifically from about 45% to about 55% by weight of the formulation.
Additional Ingredients
The aqueous, non-alcoholic liquid powder formulation of the present invention may include one or more additional ingredients. Such ingredients may improve a quality of the liquid powder formulation itself, a benefit delivered by the liquid powder formulation, processability of the liquid powder formulation, or a combination thereof. Additional ingredients that may be used in the present invention include, but are not limited to: antifoaming agents; antimicrobial actives; anti-inflammatory agents; antifungal actives; antiviral actives; antiseptic actives; antioxidants; astringents; biological actives; colorants, deodorants; emollients; humectants; exfoliants; fatty alcohols; film formers; fragrances; fragrance solubilizers; lubricants; anti-caking agents; medicants; buffers; natural moisturizing agents; skin health agents; skin conditioning agents; skin protectants; solvents; solubilizing agents; suspending agents; surfactants; antiperspirants; abrasives; wetting agents; ultraviolet absorbing agents; sunscreens, organic and inorganic; thickening agents; solidifying agents; preservatives; combinations thereof; mixtures thereof; and, the like.
The amount of the additional ingredient or ingredients that may be incorporated into the aqueous, non-alcoholic liquid powder formulation may range from about 0.01% to about 15% by weight of the formulation, more specifically from about 0.1% to about 10% by weight of the formulation, and most specifically from about 1% to about 5% by weight of the formulation. However, it is understood that the actual amount of any given additional ingredient incorporated into the aqueous, non-alcoholic liquid powder formulation will depend upon the additional ingredient itself and the desired effect of that additional ingredient on the liquid powder formulation or to be delivered by the liquid powder formulation.

        1. Cut an 8 cm×27.5 cm strip of PP2500 transparency film (hereinafter referred to as the “first strip”). The PP2500 transparency film is commercially available from 3M, located in St. Paul, Minn.
        2. Draw two parallel lines using a Sharpie® fine point permanent marker (commercially available from Sanford, located in Chicago, Ill.) on the first strip at 1.5 cm and 7.5 cm, respectively, from the back-end of the first strip such that the lines are perpendicular to the direction of travel of the first strip as discussed in Steps 6 and 7.
        3. Coat a 40 mm×40 mm×0.85 mm layer of the test formulation, centering the coating between the two parallel lines marked on the first strip in Step 2.
        4. Attach first strip coated with the test formulation to the base of a Monitor & Slip and Friction apparatus (commercially available from TMI, located in Amityville, N.Y.), placing the first strip such that the side coated with the test formulation is facing upward.
        5. Cut a 6 cm×6 cm strip of PP2500 transparency film (hereinafter referred to as the “second strip”). Attach the second strip to the bottom of a 97.72 gram TMI sled using a double sided tape.
        6. Set the Monitor & Slip and Friction apparatus for a total pull distance of 19.0 cm at a speed of 15 mm/min.
        7. Place the TMI sled on the top of the first strip such that the second strip attached to the bottom of the TMI sled is in contact with the coating of the test formulation on the first strip. Center the TMI sled between the parallel lines drawn on the first strip. Allow the TMI sled to pull along the first strip for 19.0 cm at 15 mm/min.
        8. Remove the first strip and place in a 5VY811 heavy duty clear vinyl sheet protector with a black backing (commercially available from Avery, located in Brea, Calif.).
        9. Collect images with a HP Scan Jet 5470C (commercially available from Hewlett-Packard Company, located in Palo Alto, Calif.) with automatic options turned off. All images of the test formulation on the first strip are taken beside a Kodak Gray Scale standard (commercially available from Kodak CYM, located in New York, N.Y.) as the reference.
        10. Analyze the images of the test formulation on the first strip using the Metamorph image analysis software (commercially available from Universal Image, located in Downingtown, Pa.). The images are analyzed using a threshold value set at the 11-12 interface of the Kodak Grey Scale standard. All objects within the images with a pixel area below 2500 were rejected.

Image Measurement Definitions as Used Herein:

    Pixel Area: The number of pixels in the object.
    Texture Difference Moment (TDM): TDM is a measure of the uniformity of the gray levels in an object. Objects with uniform gray level will have a texture difference moment (TDM) close to 0. Objects with greater variation of gray level will have a larger TDM value.


The Markov texture parameters (Pressman, J. Histochem. Cytochem. 24:138, 1976) are calculated as the sum of the elements of a weighted conditional gray level transition probability matrix. Larger weights are assigned to elements far from the matrix diagonal. PL(i/j) is the conditional probability of gray level I occurring L pixels away after gray level j occurs, where L is defined as the step size. N is the number of gray levels in the object. N=8 because the object gray levels are reassigned by histogram equalization into 8 bins.

The impact of overall mixture uniformity on formulation function is critical for optimum product performance and consumer satisfaction. The more uniform the formulation the easier the use and control of mixture with regard to application to the skin. Furthermore, formulation uniformity drives the ability of a mixture to provide a smooth and comfortable feel to the skin.
For the described liquid powder formulations there are two indexes of uniformity that help define the overall quality or state of being unvarying when applied to the skin. The Optical Uniformity Index (OUI) is a measure of the freedom from variation with regard to texture and optical quality. The Extensive Uniformity Index (EUI) is a measure of the combined optical and texture characteristics as related to the ability of the formulation to spread on the skin. The lower the OUI value the more uniform the formulation. The higher the EUI value the more uniform the formulation. The most consumer preferred formulation may have both a low OUI and a high EUI.
An aqueous, non-alcoholic liquid powder formulation of the present invention may have an OUI value of about 0.1 or less, or more specifically about 0.08 or less. In other embodiments of the present invention, the aqueous, non-alcoholic liquid powder formulation of the present invention may have an OUI value of about 0.1 to about 0, more specifically about 0.1 to about 0.001, and more specifically about 0.08 to about 0.01.
An aqueous, non-alcoholic liquid powder formulation of the present invention may have an EUI value of about 300 or greater, more specifically about 370 EUI or greater. In other embodiments of the present invention, the aqueous, non-alcoholic liquid powder formulation of the present invention may have an EIO value of about 300 to about 100,000, more specifically about 350 to about 10,000, and more specifically about 370 to about 1,000.
In one embodiment of the present invention, the aqueous, non-alcoholic liquid powder formulation may have an OUI value of about 0.1 or less and an EUI value of about 300 EUI or greater. In another embodiment of the present invention, the aqueous, non-alcoholic liquid powder formulation may have an OUI value of about 0.1 or less and an EUI value of about 370 or greater. In another embodiment of the present invention, the aqueous, non-alcoholic liquid powder formulation may have an OUI value of about 0.08 or less and an EUI value of about 300 or greater. In another embodiment of the present invention, the aqueous, non-alcoholic liquid powder formulation may have an OUI value of about 0.08 or less and an EUI value of about 370 or greater.
