Description

COMPOSITIONS TO REDUCE BODY ODORS AND EXCESS OF MOISTURE BACKGROUND OF THE INVENTION Body odor is most commonly caused by fatty acids in the skin and bad odors from microbial sources. Human skin is naturally populated by numerous microorganisms that are nourished by various secreted substances in the skin (eccrine and apocrine sweat, and bait), skin cell debris, skin breakage products and the organisms themselves. Said unpleasant body odors are mainly organic molecules having different structures and functional groups, such as amines, acids, alcohols, aldehydes, ketones, phenolics, polycyclics, indoles, aromatics, polyaromatics, etc. They can also be made from functional groups containing sulfur, such as diol, mecaptan, sulfur and / or disulfide groups. Numerous attempts have been made to control or absorb body odors. Attempts have been made to inhibit the microbes responsible for the body odor of the wet / humid environment by which they need to proliferate and grow. Such efforts include the use of powders and / or antiperspirants. The body powders and powder-based compositions of the prior art have limited absorption capacities. Antiperspirants are not always preferred in a control product. body odor since, although it is used throughout the body, it can interfere with the thermal regulatory process in the body by inhibiting perspiration in the action of astringent salts. Additionally, such salts can be irritating to a large number of users, particularly when applied to sensitive areas such as the pelvic region. Other deodorant compositions intended to combat / control odor associated with skin secretions, which have been described in the chemical and cosmetic literature, include emulsion sticks or suspensoid sticks, aerosols, movable ball deodorants, pads, pump sprays , and even bars of soap. Said known deodorants try to control the odor by a variety of means. For example, the patent of E.U.A. 5,525,331, to Betts, issued June 11, 1996, discloses compositions that inhibit the growth of microorganisms in bodily secretions. Deodorants can also include antibacterial compounds that help destroy / control the amount of bacteria present in the skin, thus minimizing the odor produced by the bacterial metabolism of skin secretions. Zeolites are known odor absorbers. However, said solid odor absorbers, in addition to the known activated charcoal odor absorbers, lose functionality when wet. Therefore, when they are moistened by body fluids or when they are carried in an aqueous solution, said odor absorbers are not they prefer, since they lose their desired odor-absorbing characteristics.

In addition, zeolites can cause a "rough" feeling if they are deposited heavily on the skin. In addition to the aforementioned attempts to control and / or absorb body odor, numerous attempts have been made to cover body odors with other scents or perfumes. However, perfumes are often inadequate to completely cover body odors and can be irritating to the user when used only to control odor. Thus, there still exists a need for an improved odor and moisture absorbing composition, which is essentially free of irritating ingredients such as astringent perfumes or antiperspirants and which is safe and effective for use throughout the body. Most particularly, there is a need for a suitable composition that is left on the skin and is capable of absorbing a broad spectrum of body odors and excess moisture that are not completely suppressed by the aforementioned means. It has been found that such controlled control of body odor and moisture can be safely delivered to the entire body by the application of a composition, which is left on the skin, which incorporates odor absorption, cyclodextrin that does not form complexes.; highly effective moisture absorbing ingredients; and a powder vehicle. It has been found that a particular advantage of the present invention is the ability to provide convenient, non-irritating odor and moisture protection when applied to concealed areas of skin such as the pelvic region, the outer vagina, the underwear area, the bra line, the skin folds, which can be very sensitive. In addition, it has been discovered that the aforementioned benefits can be supplied in a powder vehicle that also optionally provides skin assistance benefits to the user such as protection and / or wetting. These and other objects of the present invention will become apparent from the following detailed description. All percentages, ratios, and parts of the present, in the specification, examples and claims are by weight unless otherwise specified. The term "g", as used herein, refers to gram. The term "my", as used herein, refers to millimeter.

BRIEF DESCRIPTION OF THE INVENTION The present invention relates to a perfume free powdery odor absorbent composition, which is safe for use on the skin, comprising from about 0.1% to about 25% by weight of the composition, of cyclodextrin which does not form complexes; and a powder vehicle. The present invention also relates to a powdered odor and moisture absorbent composition which additionally is from about 5% to about 60% by weight of the composition, of a highly effective moisture. The compositions of the present invention may also contain additional odor control agents selected from the group consisting of zeolites, activated charcoal, sodium bicarbonate, anti-microbial agents and antiperspirants. The present invention also relates to the use of the aforementioned compositions in the reduction of body odor and excess moisture in hidden sites of the skin.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an odor absorbing composition, and optionally perfume free moisture, dry powder. The present invention also relates to the use of the aforementioned powder composition in the reduction of body odor and excess moisture of the hidden sites of the skin wherein the powder composition is applied to the concealed skin. The composition can be applied directly to the hidden skin by spraying, shaking in a bottle or can and applied by hand, or applied by a cloth that is dry. The composition of the present invention comprises dry ingredients which preferably have a particle size of from about 1 to about 100 microns; most preferably from about 1 miera to about 600; and most preferably from about 1 miera to about 20 micras. As used in the present, the particle size refers to the largest particle dimension and the last (or primary) particles. The term "hidden skin", as used herein, refers to regions of the human body covered by undergarments, such as the pelvic area, the panty area, and the bra line; and folds of the skin or intertriginous regions, where there is a continuous contact between the skin. The term "body fluids", as used herein, includes eccrine sweat, apocrine sweat, bait, reasonable moisture accumulation of transpidermal water loss, vaginal discharge, urine, and mixtures thereof. The term "excess moisture", as used herein, refers to an unwanted and / or unhealthy level of bodily fluids deposited on human skin. The term "body odor", as used herein, refers to odors that are generated as a result of the natural functioning of a human body. Such odors include, but are not limited to, odors produced by microorganisms of human skin (i.e., bacterial composition of skin secretions), upna, or vaginal discharge, and mixtures thereof. The term "total body" refers to the total external surface of human or mammalian skin.

The term "vaginal odor" refers specifically to those body odors that emanate from the pelvic region of a woman, particularly the vagina and the area of the panties. A detailed description of the essential and optional components of the present invention are given below. CICLQDEXTRINA. As used herein, the term "cyclodextrin" includes any known cyclodextrin such as unsubstituted cyclodextrins containing from 6 to 12 glucose units, especially alpha-cyclodextrin, beta-cyclodextrin, gamma-cyclodextripa and / or their derivatives and / or mixtures thereof. The term "cyclodextrin which does not form complexes" as used herein means that the cavities within the cyclodextrin of the composition of the present invention must remain essentially unfilled before application to the skin to allow the cyclodextrin to absorb Several odor molecules when the composition is applied to the skin. Preferred cyclodextrins for use in the present invention are alpha-cyclodextrin, beta-cyclodextrin, gamma-cyclodextrin and / or their derivatives. Most preferred are beta-cyclodextrin, hydroxypropyl alpha-cyclodextrin, hydroxypropyl beta-cyclodextrin, methylated alpha-cyclodextrin or methylated beta-cyclodextrin. The most preferred is beta-cyclodextrin. It is also preferable to use a mixture of cyclodextrins. These mixtures absorb body odors more widely if subjected to complexes with a wide range of odoriferous molecules that have a wider scale of molecular sizes. The cyclodextrin levels are from about 0.1% to about 25%, preferably from about 1% to about 20%, most preferably from about 2% to about 15%, most preferably from about 3% to about 10% by weight of the composition. Complex formation between cyclodextrin and odoriferous molecules occurs rapidly when they are moistened with body fluids. The above is convenient for the user because cyclodextrins, when found in dry skin, will not fill their cavities with other environmental scents that would otherwise make them less efficient to absorb body odors. Most particularly, in the solubilization of the cyclodextrins by body fluids, the isolated cavities become available to form inclusion complexes with the body odor molecules. In this way, finally, the availability of cyclodextrin that does not form solubilized complexes is essential for the development of effective and efficient odor control. Cyclodextrins having lower particle sizes aid in the provision of higher cyclodextrin surface availability for odor absorption and are therefore preferred. As used herein, the particle size refers to the largest dimension of the particle and the last (or primary) particles. The small particle cyclodextrins of the present invention are those having a particle size of less than about 12 microns, preferably less than about 10 microns, and most preferably less than about 5 microns. A more complete description of the cyclodextrins, cyclodextrin derivatives and ciciodextrin particle sizes useful in the present invention can be found in the U.S. Patent. No. 5,429,628, Trihn et al., Issued July 4, 1995, which is incorporated herein by reference in its entirety. POWDER VEHICLE.
