Furthermore, the present invention also relates to methods for treating or preventing topically-treatable microbial infections, especially diseases of the oral cavity, oral malodor, and to whiten teeth, in humans or other animals, by utilizing the above compositions. These compositions are effective in killing, and for a period of time suppressing the growth of, the microorganisms which cause topically-treatable infections, especially diseases of the oral cavity, such as plaque, gingivitis, periodontal disease, and breath malodor. These compositions are also effective to whiten teeth.

Description: ANTIMICROBIAL PEROXY ACID ORAL CARE COMPOSITIONS AND METHODS TECHNICAL FIELD This invention relates to topical compositions, especially oral care compositions, including mouth rinses, toothpastes, gels, tooth powders, chewing gums, mouth sprays, lozenges (including breath mints), and sachets, comprising a peroxy acid compound and salts/esters thereof with an ion source such as chloride ion, bromide ion, thiocyanate ion, and/or iodide ion, source. In addition this invention relates to topical compositions, especially oral care compositions resulting from the mixture of a peroxy acid compound and salts/esters thereof with an ion source such as chloride ion, bromide ion, thiocyanate ion, and/or iodide ion, source. This invention further relates to methods for treating or preventing topically- treatable microbial infections, especially diseases of the oral cavity, such as gingivitis, plaque, periodontal disease, and/or breath malodor, and/or for the whitening of teeth, in humans or other animals, by applying the above compositions to the oral cavity and/or teeth. These compositions may further be used for treating or preventing topically-treatable microbial infections of the skin and mucous membranes. BACKGROUND OF THE INVENTION Bacteria are a part of the normal flora of the body. They also are prevalent on all mucous membrane surfaces as indigenous flora. Given the proper circumstances and opportunity to penetrate tissues, microbes from the indigenous flora set up infections. Furthermore, periodontal disease is also an undesirable condition which has widespread occurrence. Periodontal disease is a major cause of tooth loss in adults, beginning as early as age 35. Even by age 15, it is possible that 4 out of 5 persons already have gingivitis and possibly as many as 4 out of 10 have periodontitis. Periodontal disease affects the periodontum, which is the investing and supporting tissues surrounding a tooth (i.e., the periodontal ligament, the gingiva, and the alveolar bone.) Gingivitis and periodontitis are inflammatory disorders of the gingiva and the deeper periodontal tissues, respectively. It is well accepted that periodontal disease is associated with the accumulation of plaque on the teeth. The teeth are coated with a salivary proteanaceous material (pellicle) and thereafter streptococci adhere to this coating. Gingivitis occurs from the dental plaque, and periodontitis is caused by the infection- spreading to the periodontal pocket or space between the gingiva and the tooth root. Furthermore, consumers are very interested in making their teeth whiter. Consumers consider people with whiter teeth as having more personal confidence and even better social acceptance. Teeth comprise both an inner dentin layer and an outer hard enamel layer. The enamel layer protects the inner dentin layer and its live tissue and serves as the contact surface for mastication of solid food. The enamel layer is generally translucent and slightly off-white in color. It is also considered porous since the hydroxy apatite crystals that comprise the enamel form microscopic hexagonal rods or prisms having microscopic pores or channels between them. As a result of this porous structure, staining agents and discoloring substances, such as antibiotics, foods containing coloring materials, coffee, cola, tea, tobacco, etc., can permeate the enamel and change its surface to appear yellow or brownish in color. While good oral hygiene, as achieved by brushing the teeth with a cleansing dentifrice, may help reduce the incidence of stain, gingivitis, plaque, periodontal disease, and/or breath malodor, it does not necessarily prevent or eliminate their occurrence. Microorganisms contribute to both the initiation and progression of gingivitis, plaque, periodontal disease, and/or breath malodor. Thus, in order to prevent or treat these conditions, these microorganisms must be suppressed by some means other than simple mechanical scrubbing. In addition, simple mechanical scrubbing will not be entirely effective to remove all stain types and/or to whiten the teeth. BACKGROUND REFERENCES Peroxy acids, including monoperphthalate, used alone, are known in the art as bleaching agents in laundry applications and for tooth staining as well as for disinfecting/sterilizing hard surfaces, cloth diapers, removable orthodontic appliances, etc. For example, European Patent Application No. 27,693, published April 29, 1981, Interox Chemicals Limited, discloses the magnesium salts of peroxycarboxylic acids, including the magnesium salt of monoperphthalic acid, and processes for preparing these compounds. The compounds are used as bleaching agents in washing compositions. European Patent Application No. 96,525, published Dec. 21, 1983, Interox Chemicals Limited, discloses compositions containing magnesium salts of organic peroxy acid/carboxylate compounds, including magnesium monoperphthalate. These compositions are used for the cleansing and sanitization of reusable diapers. Great Britain No. 2,137,882, published Oct. 17, 1984, filed by Interox - Chemicals Limited, discloses disinfectants containing magnesium peroxycarboxylates, including magnesium monoperphthalate. These compositions are used for disinfecting/sterilizing hard surfaces such as toilets or drains, or equipment used in medical/veterinary or food processing environments. U.S. Pat. No. 4,490,269, issued Dec. 25, 1984, Gallopo, discloses cleansing compositions comprising an effervescent agent and a monoperphthalate, or an effervescent agent and potassium monopersulfate and a monoperphthalate, as bleaching agents. These compositions are used to clean removable orthodontic appliances such as false teeth, dental plates and bridges. European Patent Application No. 133,354, published Feb. 20, 1985, Interox Chemicals Limited, discloses compositions, generally in tablet form, containing a peroxygen compound (including monoperphthalate) and an effervescence generator. These compositions are dissolved in water to produce a bath in which to soak, and thereby cleanse, removable dentures. U.S. Pat. No. 3,988,433, issued Oct. 26, 1976, Benedict, and Great Britain Pat. No. 1,477,691, issued Oct. 19, 1977 to Jones et al., disclose peroxy acid compositions to remove stains from teeth. Moreover, references have disclosed monoperphthalic acid combined with H2O2, fluoride or bis-biquanide compounds. For example, U.S. Pat. No. 4,990,329, Sampathkumar (P&G), issued February 5, 1991, U.S. Pat. No. 5,110,583, Sampathkumar (P&G), issued May 5, 1992, and U.S. Pat. No. 4,670,252, Sampathkumar (P&G), issued June 2, 1987, describe compositions and methods of treating or preventing topical anaerobic infections, especially gingivitis, periodontal disease and acne, by applying a safe and effective amount of a "singlet oxygen generating organic peroxy acid compound", e.g. an organic molecule which has at least one -CO3H. The "singlet oxygen generating organic peroxy acid compound" includes monoperphthalic acid. For enhanced stability a preferred embodiment is the magnesium salt of the monopeφhthalic acid in a pharmaceutically acceptable carrier including toothpaste, mouth rinse, chewing gum, mouth spray, lozenge and sachets. U.S. Pat. No. 4,716,035, Sampathkumar (P&G), issued December 29, 1987, describes oral compositions comprising 1, 12 dodecanedioic peroxy acid or monopeφhthalic acid and a fluoride ion source, for use in treating or preventing diseases of the oral cavity, e.g. gingivitis, with reduced staining of teeth or dentures. U.S. Pat. No. 4,886,658, Charbonneau et al. (P&G), issued December 12, 1989, describes compositions and methods for treating plaque, gingivitis, and periodontal disease, the compositions comprising a substituted or unsubstituted_ monopeφhthalate compound and a bis-biguanide compound (preferably chlorhexidine or alexidine). The combination of both compounds together or administered sequentially results in a synergistic benefit in anti-plaque activity and reduces staining of teeth caused by the bis-biguanide compound. U.S. No. 5,085,852, Banks (P&G), issued February 4, 1992, describes compositions and methods for treating microbial infections in the oral cavity, the compositions comprising a monopeφhthalic acid compound formulated into a rapidly dissolving powder matrix. Prior art compositions have not been entirely satisfactory for the treatment and/or prevention of these skin and mucous membrane diseases, oral cavity diseases, oral malodor or for the whitening of teeth. Therefore, additional efficacious compositions and methods of treatment for these puφoses are desirable. The present invention relates to the suφrising discovery that when a peroxy acid compound or salts/esters thereof is used in combination with a chloride, bromide, thiocyanate, and/or iodide ion source, the compositions will be effective for the treatment or the prevention of topically-treatable microbial infections, especially diseases of the oral cavity, such as gingivitis, plaque, periodontal disease, and/or breath malodor, and/or for the whitening of teeth, in humans or other animals. It is the puφose of the present invention to provide topical compositions, especially oral care compositions (i.e. mouth rinses, toothpastes, gels, tooth powders, chewing gums, mouth sprays, lozenges, and sachets) comprising (or to provide topical compositions resulting from the mixture of): a.) a safe and effective amount of a peroxy acid compound, or pharmaceutically- acceptable salts or esters thereof; b.) a safe and effective amount of a chloride, bromide, thiocyanate, and/or iodide ion source; and c.) a pharmaceutically-acceptable, topical excipient. Furthermore, it is the puφose of the present invention to provide methods for treating or preventing topically-treatable microbial infections, especially diseases of the oral cavity, oral malodor, and to whiten teeth, in humans or other animals, by utilizing the above compositions. These compositions are effective in killing, and for a period of time suppressing the growth of, the microorganisms which cause topically-treatable infections, especially diseases of the oral cavity, such as plaque, gingivitis, periodontal disease, and breath malodor. These compositions are also effective to whiten teeth. SUMMARY OF THE INVENTION The present invention relates to compositions, especially shampoos, roll sticks, gels, creams, ointments, rinses, and oral care compositions such as mouth rinses, toothpastes, tooth powders, mouth sprays, chewing gums, lozenges (including breath mints), sachets, and bleaching kits, etc., for the treatment of topically-treatable microbial infections, comprising the reaction mixture of: (1) a safe and effective amount of a peroxy acid compound, or pharmaceutically-acceptable salts or esters thereof; (2) a safe and effective amount of an ion source selected from the group consisting of a chloride ion, bromide ion, thiocyanate ion, iodide ion and mixtures thereof; and (3) a pharmaceutically-acceptable, topical excipient or carrier.

These compositions are also effective to whiten teeth. DETAILED DESCRIPTION OF THE INVENTION The present invention relates to compositions and methods of treating or preventing topically-treatable microbial infections, especially diseases of the oral cavity (e.g. plaque, gingivitis, periodontal disease), breath malodor, and for whitening teeth, in humans or other animals by topically applying to the tissue and/or teeth, a safe and effective amount of a peroxy acid compound or salts or esters thereof, combined with a safe and effective amount of a chloride, bromide, thiocyanate, and/or iodide ion source. By "topically-treatable anaerobe infections" or "topically-treatable microbial infections", as used herein, is meant tissue infections which are caused by or involve microorganisims, especially anaerobic bacteria, or otherwise, and may be treated by topical application. Generally, the tissues that may be treated by topical application are external mucous membranes and mucocutaneous orifices. Non-limiting examples of anaerobe infections that my be treated by topical application include anaerobe infections of the skin or soft tissue (e.g., acne, psoriasis, dandruff, gas gangrene (anaerobic myonecrosis), gas-forming cellulitis, perirectal abscess, breast abscess, dermatological lesions, wound infections, bovine mastitis), the vagina (e.g., - vulvovaginal abscess), the uterus (e.g. uterine infections), urinary tract infections, the eyes (e.g. conjunctivitis, lid infections), the ears (e.g., otitis medial, mastoiditis), the sinuses (e.g., sinusitis), and diseases of the oral cavity (e.g., Vincent's disease, periodontal disease, etc.). Not included are internal anaerobe infections that require enteral or systemic treatment methods to deliver the active to the infected tissue, such as abdominal infections, cardiovascular infections, central nervous system infections, lung infections, stomach and intestinal infections, and bone and joint infections. Specific anaerobe infections are more fully disclosed in Finegold, Anaerobic Bacteria in Human Diseases. (Academic Press, Inc., New York, 1977), and in Anaerobic Bacteria, Role in Disease (published by Charles C. Thomas, Springfield, 111.; Albert Balows, et al., editors; 1974), the disclosures of both of which are incoφorated herein by reference. Other topical skin diseases or infections include infections of bacterial, fungal, yeast, or viral origin as well as eczema, molds, warts, itching, bug bites, chicken pox, shingles, heφes simplex lesions, etc. By "diseases of the oral cavity", as used herein, is meant diseases which are initiated and/or peφetuated by bacteria in the oral cavity, especially anaerobic bacteria, and includes such diseases as, for example, periodontal disease, gingivitis, periodontitis, gingivosis, periodontosis, periodontitis complex, and other inflammatory and/or degenerative conditions of the tissues within the oral cavity, plus caries, Vincent's disease, trench mouth, oral malodor, heφes simplex lesions, and apthous ulcers. Also specifically included are dentoalveolar infections, dental abscesses (e.g., cellulitis of the jaw; osteomyelitis of the jaw), acute necrotizing ulcerative gingivitis (i.e., Vincent's infection), infectious stomatitis (i.e., acute inflammation of the buccal mucosa), and Noma (i.e., gangrenous stomatitis or cancrum oris). Oral and dental infections are more fully disclosed in Finegold, Anaerobic Bacteria in Human Diseases, chapter 4, pp. 78-104, and chapter 6, pp. 115-154 (Academic Press, Inc., NY, 1977), the disclosures of which are incoφorated herein by reference in their entirety. The compositions and methods of treatment of the present invention are particularly effective for treating or preventing periodontal disease (gingivitis and/or periodontitis) and breath malodor. By "safe and effective amount" as used herein is meant an amount of a peroxy acid compound, or a pharmaceutically-acceptable salt or ester thereof, and/or an amount of ion source, high enough to significantly (positively) modify the condition to be treated or to effect the desired whitening result, but low enough to avoid serious side effects (at a reasonable benefit/risk ratio), within the scope of sound medical judgment. The safe and effective amount will vary with the particular condition (e.g., disease of the oral cavity or malodor, etc.) being treated the age and physical condition of the patient being treated, the severity of the condition, malodor or staining of the teeth, etc. the duration of treatment, the nature of concurrent therapy, the specific form (i.e., acid, salt, and/or ester) of the compound or ion employed, and the particular vehicle from which the compound or ion is applied. By "toothpaste" as used herein is meant paste, powder, and gel formulations unless otherwise specified. By "oral care composition" or "oral composition" as used herein is meant a product which is not intentionally swallowed for puφoses of systemic administration of therapeutic agents, but is retained in the oral cavity for a sufficient time to contact substantially all or some of the dental surfaces and/or oral mucosal tissues for puφoses of oral activity. Although certain peroxy acids are described in the art for use in oral care products, they suffer from poor utilization problems due to short exposure in the oral cavity and/or stability problems. Therefore, the present invention relates to compositions or methods utilizing peroxy acids whose efficacy and stability are enhanced by the addition of a source of bromide ion, iodide ion, chloride ion and/or thiocyanate ion. The Peroxy Acid Compound It is preferred that the compositions of the present invention comprise a safe and effective amount of peroxy acid compound. Preferably the compositions of the present invention comprise from about 0.1% to about 25 %, by weight of the composition, more preferably from about 0.5% to about 15 %, even more preferably from about 1% to about 10%, by weight of the composition, of a peroxy acid compound. In the broadest sense the peroxy acid compound of the present invention is any compound with a peroxy acid functionality which may be an organic or inorganic compound and contains a mono, di, tri, or poly peroxy acid functionality, or salts or esters thereof. The peroxy acid compounds of the present invention are known in the art. These compounds are disclosed in e.g. U.S. Pat. Nos. 3,075,921, Brockelhurst et al., issued Jan. 29, 1963, U.S. 3,749,674, issued July 31, 1973, U.S. 3,988,433, issued Oct. 26, 1976, Benedict; and U.S. 4,990,329, issued Feb. 5, 1991, Sampathkumar, all of which are herein incoφorated by reference in their entirety. Preferred peroxy acid compounds of the present invention include alkyl - diperoxyacid with alkylene groups containing from 5 to 11 alkyl groups including substituted alkyl groups, i.e. those with up to 2 substituents selected from the group consisting of chloro, fluoro, nitro, trifluoromethyl, trimethylammonium, carboxy, and acetyl groups, per methylene group. Unsubstituted alkyl diperoxyacids are preferred alkyl diperoxyacids. The peroxy acid compound of the present invention are preferably the 1,12- dodecanedioic peroxy acid-based agents which may be unsubstituted or substituted. The substituted 1,12-dodecanedioic peroxy acid agents may be substituted with one or more substitutes selected from the group consisting of straight or branched chain alkyl groups having from 1 to about 6 carbon atoms (preferably methyl or ethyl), phenyl, benzyl, chloro, fluoro, nitro, trifluoromethyl, trialkylammonium (e.g., trimethylammonium, triethylammonium), — CO 2 H, — CO 3 H, or mixtures thereof. Preferably, no more than about two of the carbon atoms in the 1,12-dodecanedioic acid chain is substituted. Most preferably, the 1,12-dodecanedioic acid chain is unsubstituted (i.e., — (CH 2 ) 10 — ). It is further preferred that the 1,12-dodecanedioic acid agent be the diperoxy acid (i.e., HO 3 C(CH 2 )ιoCO 3 H.) But a peroxy acid of unsubstituted or substituted 1,12-dodecanedioic acid may also be a compound having only one peroxy acid group per molecule at either the 1 or 12 position, provided there is a carboxy lie acid or carboxylate group at the other end of the carbon chain, e.g., HO 2 C(CH 2 )ιoCO 3 H. The compositions herein may also comprise mixtures of diperoxy and monoperoxy 1,12-dodecanedioic acid, and/or the pharmaceutically- acceptable salts or esters of such acids. The 1,12-dodecanedioic peroxy acid agents of the present invention are known compounds, and they may be synthesized by known methods. Such known methods and peroxy acids are disclosed in, e.g., U.S. Pat. No. 4,483, 781, to Hartman, issued Nov. 20, 1984; and in U.S. Pat. No. 3,988,433, to Benedict, issued Oct. 26, 1976.

The preferred peroxy acid compounds of the present invention also include compounds having the general structure: or its pharmaceutically-acceptable salts or esters, wherein the compound preferably has up to 3 R groups, preferably 2 R groups, more preferably 1 R group; wherein R is any substituent compatible with the peroxy acid functionality of the aromatic ring. By "substituents compatible with the peroxy acid functionality of the aromatic ring", as used herein, is meant substituents on the ring which do not react with peroxy acid groups, thereby reducing the stability and effectiveness of the compounds, for the treatment of diseases of the skin, mucous membranes, oral cavity, breath malodor, and for teeth whitening. Preferably R is hydrogen, substituted and unsubstituted saturated alkyl having from 1 to 20 carbon atoms (e.g., methyl, ethyl), substituted and unsubstituted aryl (e.g., phenyl, naphthyl), substituted and unsubstituted benzyl, chloro, fluoro, nitro, sulphonate, trifluoromethyl, trialkylammonium (e.g., trimethylammonium; triethylammonium), cyano, carboxy, carboxylate (e.g., -O-COCH3), percarboxylate (e.g., -CO3H), alkoxy (e.g., methoxy, ethoxy), iodo, bromo, substituted or unsubstituted amino, or amido group. More preferred R groups are hydrogen, saturated alkyl having from 1 to 20 carbon atoms, aryl, benzyl, chloro, fluoro, and alkoxy. Particularly preferred is where R is hydrogen, or pharmaceutically-acceptable salts or esters thereof. Particularly preferred for use in the above method for treating or preventing diseases of the skin, oral cavity, oral malodor and for teeth whitening, etc. is monopeφhthalic acid (i.e., R=H), or its pharmaceutically-acceptable salts or esters thereof. R may also be iodo, bromo, substituted or unsubstituted amino, or amido groups, but these groups are generally not preferred. Selection of substituents compatible with the peroxy acid functionality of the aromatic ring can be easily made by one skilled in the art. By "pharmaceutically-acceptable salts or esters," as used herein, is meant esters and salts of the substituted or unsubstituted peroxy acid compounds which have the same general antimicrobial properties, and which are acceptable from a toxicity viewpoint. Nonlimiting examples of pharmaceutically-acceptable salts include alkali metal (e.g., sodium, potassium), alkaline earth metal (e.g., calcium, magnesium), non-toxic heavy metal, and trialkyl ammonium (e.g., trimethylammonium). Preferred salts include divalent cations (e.g., magnesium, calcium). Peroxy acid compounds, especially magnesium monopeφhthalate, are also_ disclosed in U.S. Pat. Nos. 4,990,329, issued Feb. 5, 1991, 5,110,583, issued May 5, 1992, and 4,670,252, issued June 2, 1987, 4,716,035, issued Dec. 29, 1987, all to Sampathkumar, (P&G), all of which are incoφorated herein by reference in their entirety. Most preferred is the magnesium salt of monopeφhthalic acid, the structure which is disclosed in U.S. Pat. No. 4,670,252, which is herein incoφorated by reference in its entirety. Synthesis of substituted and unsubstituted monopeφhthalic acid compounds can be achieved by those skilled in the art using methods disclosed in, for example, European Patent Application No. 27,693, published April 29, 1981, filed by Interox Chemicals Limited; European Patent Application No. 66,992, to Interox Chemicals Limited; U.S. Pat. No. 3,075,921, to Brockelhurst et al.; "Organic Peroxides," Daniel Swern, Editor, published 1970 by John Wiley & Sons, Inc.; and in British Patent Specification No. 1,378,671; the disclosures of all of which are incoφorated herein by reference in their entirety. Synthesis of the magnesium salt of monopeφhthalic acid is disclosed in the European Patent Application No. 27,693, cited above. This compound is also commercially available from Interox Chemicals Limited. Ion Source In addition to the peroxy acid compound, the compositions and methods of the present invention also comprise a safe and effective amount of an ion source. Thus the present invention also comprises a source of bromide ion, chloride ion, iodide ion, and/or thiocyanate ion, and mixtures thereof. The ion source can be any salt of the above ions including alkali metal (e.g., sodium, potassium), alkaline earth metal (e.g., calcium, magnesium), non-toxic heavy metal, ammonium, e.g. trialkyl ammonium (e.g., trimethylammonium) and amines. An especially preferred ion source is NaCl.

By "compatible," as used herein, is meant that the components of the composition are capable of being commingled without interaction in a manner which would substantially reduce the composition's stability and/or efficacy for treating or preventing topically-treatable microbial infections, especially diseases of the oral cavity including plaque, gingivitis, periodontal disease, as well as breath malodor and to whiten the teeth, according to the method/composition of the present invention. For oral care compositions it is preferred that the carrier be buffered, or contain a buffer, capable of maintaining the pH of the oral cavity during use from about pH 4 to about pH 8, more preferred being pH from about 5.0 to about 7.5. Non-limiting examples of buffers include citrate, citrate/bicarbonate and phosphate buffers. The excipients or carriers of the present invention can include the usual and conventional components of skin care compositions such as shampoos, creams, ointments, rinses, roll-sticks, gels and oral care compositions such as toothpastes (including gels and tooth powders), mouth rinses, mouth sprays, chewing gums, lozenges (including breath mints), and sachets. These conventional components include flavors, perfumes, thickeners, humectants, abrasive, surfactants, water, alcohol, fluoride, etc. The choice of an oral carrier to be used is basically determined by the way the composition is to be introduced into the oral cavity. If a toothpaste (including gels, etc.) is to be used, then a "toothpaste carrier" is chosen as disclosed in, e.g., U.S. Pat. No. 3,988,433, to Benedict, the disclosure of which is incoφorated herein by reference (e.g., abrasive materials, sudsing agents, binders, humectants, flavoring and sweetening agents, etc.).

No. 3,988,433 to Benedict (e.g., water, flavoring and sweetening agents, etc.) Similarly, if a mouth spray is to be used, then a "mouth spray carrier" is chosen or if a lozenge is to be used, then a "lozenge carrier" is chosen (e.g., a candy base), candy bases being disclosed in, e.g., U.S. Pat. No. 4,083,955, to Grabenstetter et al., which is incoφorated herein by reference; if a chewing gum is to be used, then a "chewing gum carrier" is chosen, as disclosed in, e.g., U.S. Pat. No. 4,083,955, to Grabenstetter et al., which is incoφorated herein by reference (e.g., gum base, flavoring and sweetening agents). If a sachet is to be used, then a "sachet carrier" is chosen as disclosed in, e.g., U.S. Pat. No. 5,085,852, to Banks, which is incoφorated herein by reference (e.g., sachet bag, flavoring and sweetening agents). If a subgingival gel is to be used (for delivery of actives into the periodontal pockets or around the periodontal pockets), then a "subgingival gel carrier" is chosen as disclosed in, e.g. U.S. Pat. Nos. 5,198,220, Damani, issued March 30, 1993, P&G, 5,242,910, Damani, issued Sept. 7, 1993, P&G, all of which are incoφorated herein by reference.

Composition Use The safe and effective amount of the compositions (or reaction mixture thereof) of the present invention may be topically applied to the skin, mucous membranes, mucosal or gingival tissue of the oral cavity, or to the surface of the teeth, in several conventional ways. For example, the skin, gingival tissue or teeth may be rinsed with a solution (e.g., rinse, spray). The gingival tissue or teeth may be brushed with a dentifrice (e.g., toothpaste, gel or tooth powder), where the gingival tissue or teeth are bathed in the liquid and/or lather generated by brushing the teeth. The skin, mucous membrane, gingival tissue or teeth may be directly covered with a gel or paste. The gingival tissue or teeth may be bathed in liquid generated by chewing gum, chewing tablets, or sucking on a lozenge or sachet. - Other methods of topically applying the present composition (or reaction mix) to the skin, mucous membranes, gingival tissue and/or the surfaces of the teeth are apparent to those skilled in the art. It is preferred for the method of treatment of the present invention that the treatment be done in such a way that the pH, particularly the pH of the oral cavity, during treatment is maintained at a pH of from about 4 to about 8, more preferably from about 5.0 to 7.5, even more preferably about 6.0 to about 7.5. One way to do this is by buffering (e.g., the oral cavity) during treatment. Non-limiting examples of pharmaceutically-acceptable buffers include citrate, citrate/bicarbonate and phosphate buffers. It is also preferred that, in the method of treating diseases of the oral cavity of the present invention, the composition (or reaction mix) not be intentionally ingested. Preferably the compositions of the present invention are obtained by the combination of two phases, the first phase comprising a compound with a peroxy acid functionality and the second phase comprising an ion source such as salts of chloride, thiocyanate, bromide or iodide. These two phases can be mixed just prior to use, for example from about 5 to about 60 minutes prior to use by the consumer. Alternatively, the two phases can be combined during use of the composition by the consumer. It is preferred that the two phase are combined prior to use, so that the pH of the final composition can be adjusted (from about pH 5 to 8) for maximum effectiveness. For the method of treating skin disease or infections (e.g. bacterial, fungal, yeast, viral origin, acne, eczema, molds, warts, itching, bug bites, chicken pox, shingles, heφes simplex lesions, etc.) a safe and effective amount of the present composition (or reaction mix) is preferably applied (as a cream, gel, spray, or shampoo, etc.) to the affected tissue for at least about 10 seconds, preferably from about 20 seconds to about 10 minutes, about once per day to about 4 times per day, preferably about two times per day, for a duration of about one week to about 2 weeks or until the condition is cleared. For the method of treating diseases of the oral cavity or breath malodor of the present invention, a safe and effective amount of the present composition (or reaction mix) is preferably applied (by rinsing with a solution, directly applying a gel, applying a gel with a toothbrush, plastic strip as described below, etc.) to the gingival tissue preferably for at least about 10 seconds, preferably from about 20 seconds to about 10 minutes, more preferably from about 30 seconds to about 60 seconds. The method often involves expectoration of most of the compositions following such contact, preferably followed with rinsing, e.g. with water. The frequency of such contact is preferably from about once per week to about four times per day, more preferably from about thrice per week to about three times per day, even more preferably from about once per day to about twice per day. The period of such treatment typically ranges from about one day to a lifetime. The duration of treatment is preferably from about 7 days to about 6 months, preferably from about 3 to about 6 months, but may be shorter or longer depending on the severity of the oral disease being treated, the particular delivery form utilized and the patient's response to treatment. As mentioned above, diseases of the oral cavity can include oral soft tissue infection such as heφes simplex virus, apthous ulcers, etc. For these indications the composition ( or reaction mix) is applied on an as needed basis, possibly up to 5-6 times per day. For the method of whitening teeth of the oral cavity, a safe and effective amount of the present composition (or reaction mix) is preferably applied (without or with an oral appliance, e.g. toothbrush, tray containing the composition, plastic strips, etc.) to the teeth preferably for at least about 10 seconds, preferably from about 20 seconds to about 10 minutes, more preferably from about 30 seconds to about 60 seconds. The exact procedure to be used depends on whether the bleaching is performed by a dentist in the office, under the supervision of a dentist, or is performed directly by the consumer. For the dentist supervised procedure, the dentist makes a tooth tray using deformable plastic to fit the patient's teeth. Then an appropriate amount of the present composition (or reaction mix) is added to the tray. The patient wears the tray for a period of about 10 minutes to about 8 hours, each day for a period of 7 to 28 days or for as long as needed to get the desired whitening effect. The patient may repeat this procedure as needed to whiten their teeth. Alternatively, the consumer can purchase a generic plastic mouth tray, to be soaked in hot water for 15 minutes until soft. Then consumer bites into the tray to make an impression of their teeth. The self formed trays are then used to carry the present composition. In yet another application, the consumer applies to their teeth, a thin plastic film pre-coated with the present bleaching composition, and wears it for a period of about 10 minutes to about 8 hours as described above. The consumer uses a new strip for each application of the bleaching composition. This type of strip appliance is further described in P&G Copending Applications Serial Nos. 08/870,664, 08/870,330, 08/870,331 and 08/870,665 all filed on June 6, 1997, the disclosure of which are herein incoφorated by reference in their entirety. Other consumer in-home-use methods include brushing the present composition (or reaction mix) on the teeth or rinsing with a mouthrinse in the same manner as described above for the method of treating diseases of the oral cavity. The present invention further relates to compositions for use in the methods of treatments according to the present invention. In particular, the present invention further relates to skin composition such as shampoos, roll sticks, gels, rinses, and oral care compositions especially mouth rinses, toothpastes, tooth powders, mouth sprays, chewing gums, lozenges, sachets, and bleaching kits, comprising the reaction mixture of: (1) a safe and effective amount of a peroxy acid compound, or pharmaceutically-acceptable salts or esters thereof; (2) a safe and effective amount of an ion source selected from the group consisting of chloride, bromide, thiocyanate and/or iodide ion source; and (3) a pharmaceutically-acceptable topical excipient or carrier. All percentages used herein are by weight of the composition unless otherwise indicated. EXAMPLES The following are non-limiting examples of the present invention. A composition, for application to oral care tissues, teeth, or skin, having two phases (a) and (b) have the following components: Phase (b) Magnesium monoperphthalate. First, independently formulate phases (a) and (b). Formulate phase (a) by combining the bicarbonate and monosodium phosphate and mix until homogeneous . Thereafter add citric acid and mix until homogeneous. Add the remaining ingredients except MMPP . Mix until homogeneous and add the MMPP. The MMPP may be suspended in an unreactive organic matrix at the desired concentration using ingredients such as mineral oil, petrolatum or a mixture thereof. Formulate phase (b) by combining glycerin and CMC and mix until homogeneous. Thereafter add sorbitol and mix until homogeneous. Add xanthan gum along with citrate/citric acid and mix until homogeneous. Finally add sodium chloride and magnesium sulfate. The two phases prepared as above can be used to formulate a variety of products. By mixing (a) and (b) in a 1 : 1 weight ratio, the resulting gel can be used for whitening teeth in a tray or other device. For bleaching tough stains or difficulty bleachable teeth, the proportion of formulation (a) can be suitably increased up to a ratio of 2:1. In addition, this mixed gel can be further formulated into a toothpaste by admixing 5-10% silica, SLS and titanium dioxide. Sodium fluoride can be optionally added to phase (b) for a toothpaste composition as well. The level of the MMPP in the toothpaste composition may be 10-20%. For preparing a mouthwash formulation, 2 gms of the 1:1 gel composition may be dispersed in 15 ml of water, prior to rinsing the oral cavity. Additionally, this gel matrix thus generated can be formulated into shampoos by combining from 5-50% of the gel preparation by weight with 95-50% of a typical : Carboxy methyl cellulose. shampoo composition containing the usual surfactants, fatty alcohols, salts, EDTA conditioner, and anti-dandruff agent. Similarly, the gel matrix generated above, can be formulated into skin lotions, dermatological sprays, hand soaps, mouth rinses, and other compositions by using agents that are typically found in these product forms.
