## Background
FIELD OF THE INVENTION
The present invention relates to topical skin compositions. More particularly, the present invention relates to a powdered multi-purpose skin composition which functions as a sunscreen, an anti-perspirant, an insect/pest repellant and/or an antiseptic.
BACKGROUND OF THE INVENTION
Human skin is exposed to a variety of damaging, deteriorating and/or irritating influences. These influences include ultraviolet radiation, pollutant chemicals, wind chapping, dryness, abrasives, insect bites, allergic reactions and the like. The skin is also subjected to a variety of intrinsic influences, including age-related histological and biochemical changes, for example, which damage or deteriorate skin.
A variety of skin care products are available to improve and/or preserve the health, feel and/or appearance of skin. These products include those the purpose of which is to delay, minimize or eliminate wrinkling of skin which is associated with aging. Other skin care products include sunscreens, which prevent or minimize the damaging effects of ultraviolet radiation; antiperspirants, which reduce sweating and eliminate or minimize the growth of odor-causing bacteria on the skin; insect repellants, which prevent insect bites and stings on the skin; and antiseptics, which prevent skin infections.
Various types of sunscreens are known for preventing or minimizing damage to skin which is induced by ultraviolet radiation. A typical sunscreen includes an organic chemical compound which absorbs ultraviolet light, such as oxybenzone; an opaque material which reflects light, such as titanium oxide or zinc oxide; or a combination of both. The organic chemical and/or opaque material is typically mixed with a cream base to facilitate spreading on the skin preparatory to sun exposure.
On certain portions of the skin, such as the armpits, bacterial breakdown of perspiration causes body odor. Deodorants can be applied to these skin areas to inhibit the growth of bacteria which metabolize perspiration. Antiperspirants are applied to the skin to stop or significantly reduce perspiration, and thus, eliminate or reduce the moist, warm climate in which odor-causing bacteria thrive. In some formulations, deodorants and antiperspirants are combined to both inhibit the growth of bacteria and reduce perspiration.
Insect repellants are compositions which can be applied to skin for the purpose of preventing insects from stinging or biting the skin. While some insect repellants are insecticides which kill insects upon contact, other insect repellants mask human scent or emit a scent which is repellant to insects. Insect repellants are typically formulated as a cream which can be spread over the surface of the skin or as a pressurized liquid which can be sprayed onto the skin from a container.
Antiseptics are antibacterial or antimicrobial compositions which can be applied to skin for the purpose of killing bacteria to prevent infection, such as in the case of burned or cut skin. Some antiseptics are germicidal, or capable of killing bacteria, whereas others are bacteriostatic, or capable of preventing or inhibiting the growth of bacteria.
Skin care products such as sunscreens, antiperspirants, insect repellants and antiseptics are typically applied to the skin for a single protective purpose. What is needed is a multi-purpose skin composition which functions as a sunscreen, an anti-perspirant, an insect/pest repellant and an antiseptic.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide powdered multi-purpose skin composition which functions as a sunscreen, an anti-perspirant, an insect/pest repellant and/or an antiseptic. In one aspect of the invention, a powdered repellent formulation of the multi-purpose skin composition comprises:
a substantially homogenous powdered mixture comprising corn starch powder, zinc oxide powder, peppermint powder, basil powder, rosemary powder, eucalyptus powder, copper mica powder and silica powder spheres.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention which may be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriately detailed structure.
The present invention is generally directed to a multi-purpose skin composition which functions as a sunscreen, an anti-perspirant, an insect/pest repellant and/or an antiseptic. The multi-purpose skin composition includes a powdered repellant formulation and a powdered relief formulation. The powdered repellant formulation of the composition can be applied to skin for the preventative purposes of preventing sunburn, repelling insects and/or preventing or minimizing perspiration. The powdered relief formulation of the composition can be applied to skin for the therapeutic purpose of preventing microbial infection on burned or cut skin.
In some embodiments, the powdered repellant formulation of the composition has at least the following components: corn starch powder, zinc oxide powder, peppermint powder, basil powder, rosemary powder, eucalyptus powder, antique copper mica powder and silica powder spheres. In some embodiments, the powdered repellant formulation additionally includes lavender powder. The powdered repellant formulation may additionally include vitamin B1 (thiamine).
In some embodiments, the powdered relief formulation of the composition has at least the following components: corn starch powder, lavender powder, peppermint powder, eucalyptus powder and silica powder spheres. In some embodiments, the powdered repellant formulation additionally includes at least one of the following: zinc oxide, basil powder, rosemary powder, antique copper mica powder and vitamin B1 (thiamine).
Corn starch powder is widely used as filler for powders and helps to reduce sweating and promote coolness. Lavender powder is used in aromatherapy to promote a sense of calmness and peace. Zinc oxide powder is substantially insoluble in water but soluble in acids and alkalis. It is used as a sunscreen and antibacterial in cosmetics and exhibits excellent screening effect against UV-A and UV-B rays. Zinc oxide powder is also used extensively in cosmetic blends of foundation, eye shadow and the like.
Peppermint powder is a natural herb repellant to ants and induces a cool sensation on skin. Basil powder is a natural herb repellant to mosquitos. Rosemary powder is a natural herb repellant to cabbage butterflies, carrot flies and mosquitoes. Eucalyptus powder is a natural leaf having antibacterial, antifungal and antiseptic properties. Eucalyptus has the capability to soothe burns and promote lung health. Copper mica powder is rich in color and has a medium sparkle quality. Copper mica powder is also approved for use on the eyes, face, lips and nails.
Silica powder spheres exist as a smooth, silky, translucent, fine white powder which is used in cosmetics and are derived from the mineral silica. Silica powder spheres are highly-absorbent and can be used as an oil control medium on skin. Silica powder spheres have been used to improve slip in cosmetic blends and reduce the appearance of fine lines and wrinkles in skin. Silica is water-repellant and stable and has been successfully used in hypoallergenic and allergy-tested formulations.
Some studies suggest that orally-administered vitamin B1 (thiamine), when ingested over a period of several days, is effective in reducing mosquito bites. It is postulated that thiamine produces a skin scent which is repellent to pregnant mosquitoes. However, several weeks may be required for the scent-producing effects of thiamine to saturate the skin to the degree which is required for insect-repelling efficacy. Therefore, topical application of thiamine to the skin may be a quicker and more effective mode of promulgating the insect-repelling effects of the vitamin as compared to oral administration.
