Full Description:
BACKGROUND 
       [0001]    Humans, throughout the course of time, have removed hair from their bodies for a variety of reasons. For example, removal of hair may be done for a cosmetic purpose—for example, men commonly remove facial hair, and/or women commonly remove hair on legs. Removal of hair may be done for functional purposes—for example, swimmers commonly remove hair from their body to reduce drag in water during races. 
         [0002]    Regardless of the reason for removing hair from the skin, the skin—a sometimes delicate organ—often can become irritated during and/or after the removal of hair from the skin. 
         [0003]    In light of this background, there remains a need for improved compositions used during the act of shaving, improved methods for preparing compositions used during the act of shaving, and/or improved methods for shaving. 
       SUMMARY 
       [0004]    In certain aspects, the present disclosure relates to improved compositions, improved methods for preparing compositions, and/or improved methods for shaving hair. In certain preferred aspects, the improved compositions for shaving include SD alcohol 40-B, isopropyl myristate, polysorbate 20,  camellia sinesis  leaf extract, benzophenone- 1 , steric acid, propylene glycol, mineral oil, cetyl alcohol, glycerol stearate, S.E.  Aloe barbadensis  leaf extract, and/or shea butter. 
         [0005]    In further aspects, the improved compositions may include one or more colorants, and/or one or more fragrances. In certain preferred embodiments, the colorants include, but are not limited to Green 5, Yellow 10, and/or Orange 4. 
         [0006]    In certain aspects, the improved compositions are a liquid phase of matter. In other embodiments, the composition is not a foam, gel, and/or solid phase of matter. 
         [0007]    In other aspects, the improved compositions and/or methods of preparing the improved compositions of the present disclosure may be formulated by mixing one or more pre-formulated personal care products and/or compositions. For example, in one embodiment, a pre-formulated composition suitable for use in embodiments disclosed herein may comprise SD Alcohol 40-B, isopropyl myristate, polysorbate 20,  camellia sinensis  leaf extract, and/or benzophenone-1, and/or another pre- formulated composition may comprise steric acid, propylene glycol, mineral oil, cetyl alcohol, glycerol stearate, S.E.  Aloe barbadensis  leaf extract, and/or shea butter. In another aspect, a pre-formulated composition suitable for use in embodiments disclosed herein may comprise glycerin, propylene glycol, sodium polyacrylate, triethanolamine, disodium edta, ethyl alcohol, DMDM, aloe vera, and/or vitamin E. 
         [0008]    In certain aspects, mixing is affected by the act of shaking the one or more compositions in a vessel. In still other aspects, a vessel may be vented to remove any pressure and/or vacuum that may form during mixing and/or shaking. In still other aspects, compositions disclosed herein may be used in improved methods for removing hair from a body and/or shaving. 
         [0009]    In additional embodiments, improved methods for shaving the skin of a body are disclosed. In one embodiment, an improved method for shaving the skin of a body may comprise the acts of applying water to the skin of a body, applying a composition to a body, and/or cutting hair from the skin of a body. In another embodiment, soap may be applied to the skin of a body before and/or after shaving. In other aspects, the water applied to the skin of a body may be cold water, warm water, and/or hot water. In still further embodiments, the skin of the body from which hair is to be removed is located on the face, scalp, arms, legs, and/or the pubic area of a body. 
         [0010]    In other embodiments, a small quantity of a composition is applied to the skin of a body. For example, in certain embodiments, the quantity of a composition applied to the skin of a body is about 0.01 fluid ounces, and/or between about 0.01 fluid ounces and about 0.1 fluid ounces. The composition may be applied to the body by spraying a composition to the hands, then transferring the composition to the area of the body to be shaved. In some embodiments, a composition may be applied to the hands or to the area to be shaved by spraying the composition. 
         [0011]    Additional embodiments of the invention, as well as features and advantages thereof, will be apparent from the descriptions herein.

       EXAMPLE 1 
     Preparation of Composition 
     Materials and Methods 
       [0023]    To an empty one quart vessel was added about 10 fluid ounces (about 1 part) of a composition of matter comprising SD Alcohol 40-B, isopropyl myristate, water, polysorbate 20, fragrance,  camellia sinensis  leaf extract, benzophenone-1 was obtained (Best Choice brand Electric Razor Pre-Shave with Soothing Green Tea, distributed by Valu Merchandisers, Co., 5000 Kansas Ave., Kansas City, KS 66106). About 20 fluid ounces (about 2 parts) of a composition comprising water, steric acid, propylene glycol, mineral oil, cetyl alcohol, glycerol stearate, S.E.  Aloe barbadensis  leaf extract, and  Vitellaria paradoxa  (shea butter) was added. One such composition is marketed and distributed under the name “Nature&#39;s Advantage” (Marianna Industries, Omaha, Neb., 66137). The vessel was then sealed, and the resulting composition shaken vigorously. 
         [0024]    During and/or after shaking, it was noticed that the vessel and composition were warm to the touch. Any pressure that developed during shaking was released by venting the vessel. 
         [0025]    The resulting composition was transferred to a manual spray bottle. 
         [0026]    Other pre-formulated compositions were tested for incorporation into the compositions of the present disclosure. For example, St. Ives Swiss formulation, St. Ives aloe vera advanced formulation, Jergens original scent formulation, Jergens cherry almond formulation, Olay body lotion, Vaseline Intensive Care herbal formulation, and/or Vaseline Intensive Care aloe vera formulation were tested. These pre-formulated compositions did not appear to work according methods of the present disclosure. Without being bound by theory, phase separation was commonly observed when these certain pre-formulated compositions were used. 
         [0027]    Various ratios and/or quantities of pre-formulated compositions were also tested for use in compositions and methods of the present disclosure. For example, ratios of about 1 to about 1, of about 1 to about 3, of about 1 to about 4 were tested. However, compositions made from these ratios of pre-formulated compositions had properties that made them less desirable. For example, compositions made from these ratios of pre-formulated compositions sometimes separated into two or more phases. 
       EXAMPLE 2 
     Preparation of Composition 
     Materials and Methods 
       [0028]    4 fluid ounces of the composition of EXAMPLE 1 was removed from the vessel and discarded. 4 fluid ounces of a composition comprising glycerin, propylene glycol, sodium polyacrylate, triethanolamine, disodium EDTA, ethyl alcohol, DMDM, aloe vera, vitamin E, and water was then added. Such a composition is marketed and distributed under the name “St. Eden Spa” baby oil gel (distributed by Core Brands, 1301 Wicomico St., Baltimore, Md. 21230). The vessel was sealed, and the resulting compositions was shaken vigorously. The resulting composition was transferred to a manual spray bottle. 
       EXAMPLE 3 
     Method for Shaving with Composition of Example 1 or Example 2 
     Materials and Methods 
       [0029]    The composition of matter from Example 1 or Example 2 was used for shaving by wetting the area to be shaved, washing the area to be shaved with soap, dabbing dry the area to be shaved, applying the composition from Example 1 or Example 2 by spraying two sprays into the hands and applying the composition to the area to be shaved, spraying two additional sprays in to the hands and applying the composition to the area to be shaved, and/or shaving the area to be shaved with a commercial multi-blade safety razor. 
       Results 
       [0030]    It was observed that by using the composition from Example 1 or Example 2, that the number of nicks in the area to be shaved was reduced, the razor blade used exhibited fewer clogs from the hair removed from the area to be shaved, and the lifetime of the safety razor blade used was increased. For example, a razor blade that would typically last for one month lasted for 11 months when the compositions from Example 1 or Example 2 was used. 
         [0031]    In addition to the above-mentioned benefits, it was also observed that severed hairs were less likely to clog the interstices between multi-blade safety razors during and after shaving when using the compositions of Example 1 and/or Example 2, and/or multi-blade safety razors lasted for an increased number of shaves. 
         [0032]    EXAMPLE 4 
       Alternative Method for Shaving with Composition of Example 1 or Example 2 
     Materials and Methods 
       [0033]    After shaving according to the procedures listed in Example 3, 2 additional sprays of the composition of Example 1 or Example 2 can be made to the hands, and the composition then applied to the area to be shaved. 
       Results 
       [0034]    It was observed that certain testers enjoyed additional benefits when the compositions of Example 1 or Example 2 were applied to the area to be shaved after shaving. For example, some testers observed reduced irritation of the area to be shaved when the composition from Example 1 or Example 2 was applied after shaving.
