CROSS REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims priority benefit, under 35 U.S.C. §119(e), of U.S. Provisional Patent Application No. 61/426,261, filed Dec. 22, 2010, the contents of which application are hereby incorporated by reference in their entirety. 
     
    
     FIELD OF THE INVENTION 
       [0002]    The present invention relates generally to compositions comprising non-allergenic latex, including latex derived from guayale. More particularly, the invention relates to an adhesive composition comprising non-allergenic latex for cosmetic application. 
       BACKGROUND 
       [0003]    A person&#39;s beauty or attractiveness can be increased by a full and voluminous set of eyelashes. False eyelashes and other cosmetic devices and materials have been used to enhance a person&#39;s appearance by providing a long, full and thick set of eyelashes on their own or by augmenting a person&#39;s natural eyelashes. However, false eyelashes need to be attached to the eyelid so that they do not dislodge or fall off during use. 
         [0004]    Cosmetic adhesive compositions containing traditional rubber Hevea latex or nitrocellulose based formulations have been utilized to attach false eyelashes during use. However, such compositions contain ingredients to which a person can experience an allergic reaction. 
         [0005]    It would be desirable to have a cosmetic adhesive that does not produce an allergic reaction. It would also be desirous to have a cosmetic adhesive that includes a non-allergenic latex. It would still further be desirous to have a cosmetic adhesive that includes a non-Hevea latex, such as guayule. 
         [0006]    It is an object of the present invention to provide a cosmetic adhesive including a non-allergenic latex. It is another object of the present invention to provide a cosmetic adhesive including a non-Hevea latex. It is yet another object of the present invention to provide a cosmetic adhesive including a guayule latex. It is still another object of the present invention to provide a method for attaching a false eyelash to a user&#39;s eyelid using a non-allergenic latex. It is yet another object of the present invention to provide a method for attaching a false eyelash to a user&#39;s eyelid using a non-Hevea latex. It is yet still another object of the present invention to provide a method for attaching a false eyelash to a user&#39;s eyelid using a guayule latex. 
       SUMMARY OF THE INVENTION 
       [0007]    Some or all of these objects are provided for by the instant invention which, in the broadest aspect, relates to compositions comprising a non-allergenic latex. The compositions may be cosmetic compositions for application to a human integument, such as makeup or the like, or may be adhesive compositions for affixing cosmetic accessory, such as false eyelashes, fake nails and extensions, and the like. In a particular implementation, methods are provided for attaching a false eyelash to a person&#39;s eyelid comprising mounting said false eyelash to said eyelid with a non-allergenic latex, preferably, a non-Hevea latex, including, without limitation, a natural latex selected from the group consisting of guayule, gopher plant, mariola, rabbitbrush, milkweeds, goldenrods, pale Indian plantain, rubber vine, Russian dandelion, mountain mint, American germander and tall bellflower. In the preferred implementations, the natural latex is guayule latex. 
         [0008]    Also provided is an adhesive composition comprising from about 15.0 wt % to about 40.0 wt % guayule latex solids; from about 0.1 wt % to about 20.0 wt % film forming agent; from about 0.1 wt. % to about 10.0 wt % gellant; from about 1.0 wt % to about 9.0 wt % plasticizer; and water. The adhesive may further include about 0.01 wt % to about 15.0 wt % of a colorant comprising a pigment selected from the group consisting of iron oxide, carbon black, and mixtures thereof.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0010]    The present invention provides a composition with a non-allergenic latex that is capable of a variety of applications including use as a cosmetic adhesive, for example in the attachment of false eyelashes, a peel-off lipstick, peel-off skincare mask with or without active ingredients, peel-off blush that contains a residual stain component for color building effects, water based nail enamel/nail wear treatment products, and temporary skin or nail tattoos, or for use in cosmetics as a long-wear flexible film former, for example for use in cosmetics such as pigmented make-up foundations, flexible coat mascara or eye liner, and the like. 
         [0011]    Non-allergenic latex includes compositions such as non-Hevea latex. Non-Hevea latex is a natural latex derived from natural sources other than Hevea, such as guayule, gopher plant, mariola, rabbitbrush, milkweeds, goldenrods, pale Indian plantain, rubber vine, Russian dandelion, mountain mint, American germander and tall bellflower as set forth in United States Patent Publication 2008/0300526 which is hereby incorporated by reference in its entirety. Since these natural latexes are not Hevea latex, they have the advantage that they do not contain the antigens that produce the type of allergic reaction that can be accompanied by the use of topically applied Hevea latex. 
         [0012]    Particularly desirable is latex derived from  Parthenium argentatum  commonly known as guayule) which is available commercially from the Yulex Corporation. This guayule latex product is an ultra-pure, high quality emulsion that is an alternative to Hevea materials. Guayule is anon-fond industrial crop that is renewable, environmentally sustainable and is currently used in several medical applications. Guayule latex is available in either a potassium hydroxide base emulsion or an ammonia base emulsion each of which contain a minimum dry rubber content of about 49% and a maximum dry rubber content of about 56%, with a total solids minimum of about 50% and a total solids maximum of about 57%. The extraction processes are set forth in U.S. Pat. Nos. 7,259,231 and 7,790,036, both of which are hereby incorporated by reference in their entirety. 
         [0013]    The present invention includes an effective amount of non-allergenic latex to affix a cosmetic material or accessory to a person. Typically, such effective amount of the non-allergenic latex is a latex solids content of from about 1.0 percent by weight (wt %) to about 90 wt % of the total composition, preferably from about 15 percent by weight (wt. %) to about 40 wt % of the total composition; and more preferably, from about 20 wt % to about 30 wt % of the total composition. 
         [0014]    The present invention also may comprise an effective amount of one or more film forming agents, including hydrophilic and hydrophobic film forming agents. The film forming agents may be any material suitable for use in a cosmetic or personal care composition including, waxes, oils, and polyols, but is preferably a film forming polymer.

         [0023]    The present invention can be formulated into the adhesive composition set forth in Example 1 below and used to attach false eyelashes. A false eyelash is typically composed of a base on which is attached a plurality of false eyelash filaments. The filaments are normally of a color similar to the natural eyelashes of the person to which they will be applied. For the purpose of the present invention, a person may also include a doll, mannequin or other human figure on which the invention is used. Before application, the eyelid of the person is usually cleaned of make-up or other debris that could interfere with the adhesive properties of the present invention. A thin application of adhesive is then applied to the base of the false eyelash. Before the adhesive dries, the false eyelash is then applied to the eye lid on or substantially adjacent to the area of the eyelid from which the person&#39;s natural eyelashes normally radiate, preferably to blend into the natural eyelashes. The false eyelashes may be applied as a single base with multiple filaments or as multiple base sections, each such section including at least one filament. 
         [0024]    As used herein, the term “consisting essentially of” is intended to limit the invention to the specified materials or steps and those that do not materially affect the basic and novel characteristics of the claimed invention, as understood from a reading of this specification. All percentages are by weight based on the total weight of the composition, unless otherwise indicated.
