Description: TREATED WIPE ARTICLES FIELD OF THE INVENTION The present invention relates to treated wipes comprising one or more layers of a water- insoluble substrate and an aqueous liquid composition comprising a water-insoluble functional ingredient wherein the water-insoluble functional ingredient is uniformly distributed on and/or into the substrate without the need for emulsifying agents. BACKGROUND OF THE INVENTION Treated wipes or paper-cloths for skin cleansing and refreshing are well known commercially and readily available to consumers. Such products typically comprise paper or non-woven fabric sheets which are wetted with a aqueous solution of water soluble or water dispersible ingredients. The difficulty presented by these ingredients is that they are typically hydrophobic and water insoluble. It is well-known to incorporate hydrophobic or water- insoluble cosmetic ingredients in the form of an oil-in-water emulsion. See U.S. Patent 4,559,157, granted Dec. 17, 1985 to Smith et al, "Cosmetic Applicator Useful for Skin Moisturizing". There are a number of drawbacks, however, associated with the emulsion approach. One is that these emulsions generally tend to be unstable. Another relates to the chemicals used to emulsify the hydrophobic component. Specifically, such chemical emulsifiers tend to keep hydrophobic materials from uniformly adhering to human skin. Furthermore, chemical emulsifiers tend to produce a sticky or tacky feeling on the skin. The present inventors have developed a process for uniformly distributing hydrophobic or water-insoluble ingredients in or onto the surfaces of wipe articles wetted with an aqueous liquid without the need for emulsifying chemicals or agents. Accordingly, it is an object of the present invention to provide treated, wetted wipes for cleansing or treating mammalian skin and/or environmental surfaces. It is also an object of the present invention to provide wetted wipes comprising water- insoluble functional ingredients wherein the water-insoluble functional ingredients are uniformly distributed on or in wipes wetted with an aqueous liquid composition without the need for emulsifying agents. These and other objects, advantages and novel features will become apparent to those skilled in the art from the following description and appended claims. SUMMARY OF THE INVENTION The present invention relates to treated wipe articles comprising: a), one or more layers of a water-insoluble substrate; and b). an aqueous liquid composition comprising: i). an effective amount of a non-encapsulated, water insoluble functional ingredient; and ii). an aqueous component wherein the aqueous liquid composition is coated onto and saturates the substrate such that the water-insoluble functional ingredient is uniformly distributed onto and/or into the substrate and wherein the substrate remains saturated with the aqueous liquid composition and further wherein the aqueous liquid composition is substantially free of surfactants or surfactant mixtures having an HLB value of from about 4 to about 18. The present invention also relates to methods of manufacturing and using the disclosed wipes. DETAILED DESCRD7TION OF THE INVENTION The present invention can comprise, consist of, or consist essentially of the essential elements and limitations of the invention described herein, as well any of the additional or optional ingredients, components, or limitations described herein. All percentages, parts and ratios are based upon the total weight of the aqueous liquid composition of the present invention, unless otherwise specified. All such weights as they pertain to listed ingredients are based on the active level and, therefore, do not include carriers or by-products that may be included in commercially available materials, unless otherwise specified. The present invention relates to treated wipe articles which provide improved skin or surface feel properties. As used herein, the term "treated wipes articles" refers to products in which one or more sheets of a water-insoluble substrate have been impregnated with an aqueous liquid composition for the purpose of rubbing the wipe product over a surface (e.g. skin) to treat the surface as needed (e.g., cleanse, condition and/or refresh). The treated wipes articles of the present invention comprise a water-insoluble substrate and an aqueous liquid composition comprising water- insoluble functional ingredients, wherein the aqueous liquid composition is coated onto or impregnated into the substrate such that the substrate is saturated with the aqueous liquid composition and such that water-insoluble functional ingredient is uniformly distributed onto and/or in the substrate and wherein the aqueous liquid composition is substantially free of conventional emulsifying surfactants. The essential and optional components used to prepare the treated wipe articles of the present invention, as well as the process for preparing and using them, are described in detail as follows: ESSENTIAL COMPONENTS A. Water-Insoluble Substrate The products of the present invention comprise a water insoluble substrate. By "water insoluble" is meant that the substrate does not dissolve in or readily break apart upon immersion in water. The water insoluble substrate is the implement or vehicle for delivering the water- insoluble functional ingredient of the present invention to surfaces in need of treatment (e.g, skin). A wide variety of materials can be used as the substrate. The following nonlimiting characteristics are desirable: (i) sufficient wet strength for use, (ii) sufficient abrasivity, (iii) sufficient loft and porosity, (iv) sufficient thickness, and (v) appropriate size. Nonlimiting examples of suitable insoluble substrates which meet the above criteria include nonwoven substrates, woven substrates, hydroentangled substrates, air entangled substrates, natural sponges, synthetic sponges, polymeric netted meshes, and the like. Preferred embodiments employ nonwoven substrates since they are economical and readily available in a variety of materials. By nonwoven is meant that the layer is comprised of fibers which are not woven into a fabric but rather are formed into a sheet, mat, or pad layer. The fibers can either be random (i.e., randomly aligned) or they can be carded (i.e. combed to be oriented in primarily one direction). Furthermore, the nonwoven substrate can be composed of a combination of layers of random and carded fibers. Nonwoven substrates may be comprised of a variety of materials both natural and synthetic. By natural is meant that the materials are derived from plants, animals, insects or byproducts of plants, animals, and insects. By synthetic is meant that the materials are obtained primarily from various man-made materials or from natural materials which have been further altered. The conventional base starting material is usually a fibrous web comprising any of the common synthetic or natural textile- length fibers, or mixtures thereof. Nonlimiting examples of natural materials useful in the present invention are silk fibers, keratin fibers and cellulosic fibers. Nonlimiting examples of keratin fibers include those selected from the group consisting of wool fibers, camel hair fibers, and the like. Nonlimiting examples of cellulosic fibers include those selected from the group consisting of wood pulp fibers, cotton fibers, hemp fibers, jute fibers, flax fibers, and mixtures thereof. Nonlimiting examples of synthetic materials useful in the present invention include those selected from the group consisting of acetate fibers, acrylic fibers, cellulose ester fibers, modacrylic fibers, polyamide fibers, polyester fibers, polyolefin fibers, polyvinyl alcohol fibers, rayon fibers, polyurethane foam, and mixtures thereof. Examples of some of these synthetic materials include acrylics such as acrilan, creslan, and the acrylonitrile-based fiber, orlon; cellulose ester fibers such as cellulose acetate, arnel, and acele; polyamides such as nylons (e.g., nylon 6, nylon 66, nylon 610, and the like); polyesters such as fortrel, kodel, and the polyethylene terephthalate fiber, dacron; polyolefins such as polypropylene, polyethylene; polyvinyl acetate fibers; polyurethane foams and mixtures thereof. These and other suitable fibers and the nonwoven materials prepared therefrom are generally described in Riedel, "Nonwoven Bonding Methods and Materials," Nonwoven World (1987); The Encyclopedia Americana, vol. 1 1, pp. 147-153, and vol. 26, pp. 566-581 (1984); U.S. Patent No. 4,891,227, to Thaman et al., issued January 2, 1990; and U.S. Patent No. 4,891,228 which are all incorporated by reference herein in their entirety. Nonwoven substrates made from natural materials consist of webs or sheets most commonly formed on a fine wire screen from a liquid suspension of the fibers. See C.A. Hampel et al., The Encyclopedia of Chemistry, third edition, 1973, pp. 793-795 (1973); The Encyclopedia Americana, vol. 21 , pp. 376-383 (1984); and G.A. Smook, Handbook of Pulp and Paper Technologies. Technical Association for the Pulp and Paper Industry (1986); which are incorporated by reference herein in their entirety. Substrates made from natural materials useful in the present invention can be obtained from a wide variety of commercial sources. Nonlimiting examples of suitable commercially available paper layers useful herein include Airtex*\ an embossed airlaid cellulosic layer having a base weight of about 71 gsy, available from James River, Green Bay, WI; and Walkisoft^-, an embossed airlaid cellulosic having a base weight of about 75 gsy, available from Walkisoft U.S.A, Mount Holly, NC. Methods of making nonwoven substrates are well known in the art. Generally, these nonwoven substrates can be made by air-laying, water-laying, meltblowing, coforming, spunbonding, or carding processes in which the fibers or filaments are first cut to desired lengths from long strands, passed into a water or air stream, and then deposited onto a screen through which the fiber-laden air or water is passed. The resulting layer, regardless of its method of production or composition, is then subjected to at least one of several types of bonding operations to anchor the individual fibers together to form a self-sustaining web. In the present invention the nonwoven layer can be prepared by a variety of processes including hydroentanglement, thermally bonding or thermo-bonding, and combinations of these processes. Moreover, the substrates of the present invention can consist of a single layer or multiple layers. In addition, a multilayered substrate can include films and other nonfibrous materials. Processes for preparing hydroentangled webs are well known in the art. See, for example, Evans; U.S. Patent 3,485,786; issued December 23, 1969; Kalwarres; U.S. Patent 2,862,251 and Griswold; U.S. Patent 3,025,585, all of which describe hydroentangling procedures generally and all of which are herein incorporated by reference.
