Description

Chewable Gum Compositions

Field of the Invention

Presented herein are chewable gum compositions. The chewable gum compositions described herein provide breath freshening and/or teeth cleaning effects and/or the release of medicinal agents, and may be used for ameliorating, reducing, treating, or preventing conditions in the oral cavity, such as halitosis and/or gingivitis.

Background of the Invention

Oral malodor (halitosis, Fetor ex ora) is a common and disturbing condition that is prevalent in the general population. Aylikci, B. U. & Colak, H., Halitosis: From diagnosis to management , 4 JOURNAL OF NATURAL SCIENCE, BIOLOGY, AND MEDICINE, 14-23 (2013). Halitosis is formed by volatile molecules formed as a result of pathological or nonpathological causes, primarily originating in the oral cavity. Studies have pointed to bacterial putrefactive activity as one of the primary causes of this condition. Numerous types of bacteria are responsible for the malodor production, including, for example, Porphyromonas gingivalis , Fusobacterium nucleatum , and Prevotella intermedia. These bacteria reside in various locations within the oral cavity and can break down organic materials, including peptides and proteins present in saliva, fluids, or food debris into constituent molecules that are malodorous. For example, amino acids ( e.g . methionine, cysteine, tryptophan, lysine) may be catabolized to various malodorous volatile compounds, such as methylmercaptan, hydrogen sulfide, indole, skatole, and cadaverine.

It is further recognized that with poor oral hygiene, food debris and dental bacterial plaque can accumulate on the teeth and tongue, and cause caries and periodontal diseases like gingivitis and periodontitis. The inflammation of gingival and periodontal tissues creates typical sources for oral malodors and plaque-related periodontal disease can increase the severity of halitosis. Other forms of periodontal disease, such as acute necrotizing ulcerative gingivitis, pericoronitis, Vincent's disease, or aggressive forms of periodontitis, can also increase unpleasant breath odor.

In addition, respiratory viruses are the most frequent causative agents of disease in humans. The most common viruses include influenza virus, rhinovirus, coronaviruses, respiratory syncytial virus, parainfluenza virus, metapneumovirus, adenoviruses, and bocaviruses. Many of these infectious agents may cause sporadic illness, seasonal epidemics, or pandemics. It is apparent that there continues to be a long-felt need for compositions that can be used to ameliorate, reduce, treat, or prevent any of the foregoing conditions and disease in the oral cavity. And with regard to respiratory viruses, although the primary route of infection may be in the nasal cavity, viral shedding generally also occurs in the oral cavity, and providing anti -viral medicinal agents to the oral cavity may nonetheless help adjacent nasal cavity, and foster a virus-hostile environment throughout the oronasal region. It is therefore an object of the present invention to provide compositions for treating malodor and/or other plaque-related conditions and diseases in the oral cavity, and to provide medicinal agents to promote a virus-hostile environment.

Detailed Description

The present application provides a chewable gum composition. The term “chewable gum” as used herein encompasses various embodiments of compositions that are chewed in the mouth (oral cavity). In some embodiments, the chewable gum composition is an edible composition meant to be ingested. In such embodiments the composition may disintegrate, dissolve, or otherwise reduce in size, as a result of chewing and/or presence in the mouth, and ultimately be ingested. In some embodiments, the composition is chewed while being retained in the mouth for an extended period of time, usually lasting minutes or tens of minutes or longer, and ultimately, generally, is not ingested. In any of these embodiments, the chewable gum composition contacts the teeth for a time sufficient to ameliorate, reduce, treat, or prevent any of the conditions and diseases in the oral cavity discussed herein.

In the present application and the claims appended hereto, the amounts of any component included in compositions according to the invention is generally provided as a weight percentage, e.g., as a part by weight expressed as a percentage of the entire weight of the composition. The weight percentage is sometimes expressed as a particular value and sometimes as a range between one value and another value. Any such values described herein, whether given as a single value, as one or more endpoints for a range, or the range itself, describe the numeric value and also approximations of that numeric value, even if the antecedent term “about” is not explicitly used. As those of ordinary skill in the art are aware, weight percentages of the components in gum compositions may vary from (greater than or less than) a nominal amount by 1%, by 2%, by 5%, and even by 10% without substantively changing the properties of a given composition, although commercially desirable properties may have a smaller tolerance.

When a range is described using an upper endpoint (e.g., up to certain value), a lower endpoint (e.g., at least a certain value), or an upper and lower endpoint, it should be understood to describe each value up to, more than, or within the endpoint(s) described, including the endpoint value itself and approximations thereof. Where the amount of a component is expressed as being “up to” a certain value, unless the context indicates otherwise, it should be understood that such component may be included in a finite amount or that such component might not be present in the composition, i.e., the amount may be zero. Such component may be optionally included in a particular composition.

When a component is described as serving a particular function or being one of a particular class of components, it should be understood that such component is not thereby limited. Such component might, for example, serve more than one function or represent more than one class of component in an embodiment. Moreover, such component might not serve the particular function referred to in an embodiment, in which case the function should be understood as merely a convenient label.

(2) Use of Compositions

In another aspect, the chewable gum compositions disclosed herein may be used for oral care. In some embodiments, the chewable gum composition is useful for treating malodor (or halitosis) and/or a plaque-related periodontal disease (e.g., gingivitis).

Oral malodor or halitosis, also commonly referred to as bad breath, is the result of volatile sulfur compounds, carboxylic acids and amines building up in the oral cavity. The malodorous compounds are generated primarily through putrefactive action of oral microorganisms. These microorganisms are commonly found in saliva and dental plaque and may be derived from proteinaceous food particles trapped between the teeth, in the gingival crevice, or adhering to the mucous membranes.

Additionally, oral malodor may be the result of poor oral hygiene, digestive system problems, disease, diet, or a combination of any of these factors. For instance, the build-up of putrid matter which causes malodor can also lead to the formation of plaque, the origin of dental caries, gingivitis, and dental calculus. The inflammation of gingival and periodontal tissues creates typical sources for oral malodors, and plaque-related periodontal disease can increase the severity of halitosis. Other forms of periodontal disease, especially acute and aggressive forms such as acute necrotizing ulcerative gingivitis, pericoronitis, Vincent's disease, or aggressive forms of periodontitis, can also increase unpleasant breath odor.

The chewable gum compositions may be administered to a subject for the purpose of ameliorating, reducing, treating, or preventing any of the conditions or diseases in the oral cavity of the subject, such as halitosis, gingivitis, periodontitis, or other plaque-related conditions or diseases, or the common cold and other virus-related conditions. The purpose of ameliorating, reducing, treating, or preventing applies to the symptoms exhibited by the subject, the presence of a causative agent, and/or the environment in the oral cavity that would otherwise support the presence of a causative agent.

In one aspect, methods of using the compositions for ameliorating, reducing, treating, or preventing the conditions and diseases described herein include administering to a subject a chewable gum composition, and having the subject actively chew (masticate) or work over using the teeth the composition so as to contact the composition with the various surfaces in the subject’s mouth, including the teeth, gums, tongue, and other interior surfaces of the oral cavity and oropharynx. The composition may be consumed in the subject’s oral cavity for seconds or tens of seconds, particularly for edible compositions, or minutes or tens of minutes or longer, particularly for chewing gum or bubble gum compositions. The chewable gum compositions may be administered one or more times in a day.

(3) Preparation of Compositions

The chewable gum composition as described herein can be prepared by standard techniques for preparing gum compositions suitable for chewing. If the composition comprises more than one phase, in general, the different phases will be prepared separately, with materials of similar phase partitioning being added in any order. The two phases will then be combined with vigorous stirring to form the multiphase system such as an emulsion or dispersion. Any ingredients in the formulation with high volatility, or which are susceptible to hydrolysis at high temperatures, will usually be added post mixing of the different phases with gentle stirring. Typical confectionery methods are suitable for manufacturing of compositions of the present invention. Finally, if the products are coated, the coating step is typically conducted as a final step. The coating can be applied by panning or spray dried techniques commonly known to those skilled in the art.

Materials:

Exemplary ingredients used in preparing chewable gum compositions as described herein are listed in Table 1 below. Table 1. Exemplary Ingredients.

Example 1: General process for preparing a chewable gum composition.

In one exemplary embodiment, chewable gum compositions according to the present disclosure were produced by the following procedure. The gum base was first softened by incubation at 80-85°C for five to six hours. Following incubation, other components were mixed and kneaded as follows:

1. Powder ingredients comprising greater than 5% of the target mixture were first entered into a mixer and mixed for two minutes.

2. Powder ingredients comprising less than 5% of the target mixture were then entered into the mixer and mixed for 5 minutes.

3. Liquid-phase ingredients were then added to the mixer and further mixed for three minutes.

4. The softened gum base was then poured into the mixer and kneaded for 20 to 30 minutes. After mixing and kneading, a first drying step was performed by transferring the chewable gum composition onto a tray and incubating the chewable gum composition at 20°C for 24 hours under 40% humidity. Next, the chewable gum composition was pulverized into a powder and filtered through a 20 mesh screen. Metal contaminants were then removed from the filtered powder by exposure to a strong magnet. A second drying step was performed by incubating the powder at 20°C for 7 hours under 40% humidity.

Following the second drying step, the powder was mixed with magnesium stearate in a mixer at a 49: 1 ratio (powdenmagnesium stearate). The mixture was then pressed into 2 gram tablets, processed through a dust remover, and visually inspected. Thereafter, the tablets may be packaged. Example 2: Batch 1.

Example 12: Effects of Chewable Gum Compositions on Oral Malodor.

Oral malodor or halitosis, commonly referred to as bad breath, is the result of volatile sulfur compounds, carboxylic acids and amines building up in the oral cavities. The chewable gum composition set forth in Batch 4 (Table 5) was administered to twenty-two human subjects, and concentrations (in parts-per-billion, hereinafter - ppb) of mouth odor gases were measured before and after the subjects chewed the chewable gum composition for ten minutes. Mouth odor gases were measured using a Twin Breasor II (iSenlab Inc.) apparatus.

Each subject brushed their teeth at least two hours before the test and did not use any oral hygiene product thereafter. Each subject’s mouth was first rinsed with water and then each subject’s breath was analyzed to determine the concentrations of H2S and CH3SH gases present prior to administering the chewable gum composition. The subjects were then administered two 2 gram tablets of the chewable gum composition, and allowed to chew the composition for ten minutes. Each subject’s breath was then analyzed to determine the concentrations of H2S and CH3SH gases present following use of the chewable gum composition.

Of the twenty -two subjects tested, no subjects exhibited an increase in breath EES concentrations, and one subject exhibited an increase in breath CH3SH concentration. Surprisingly, a single use of the chewable gum composition significantly decreased breath H2S concentrations all eleven subjects that exhibited a measurable amount of EES before administration, and decreased breath CH3SH concentrations in all ten subjects that exhibited a measurable amount of CH3SH before administration. These effects were observed in both severe cases (EES or CH3SH concentration > 100 ppb prior to use of the chewable gum composition) and non-severe cases (EhS or CH3SH concentration < 100 ppb prior to use of the chewable gum composition). Table 12 and Table 13 illustrate the observed reduction of mouth odor gas concentrations for EhS and CH3SH, respectively. As demonstrated by this study, ten minutes of chewing the chewable gum composition can reduce or eliminate severe and non-severe conditions of mouth odor gases associated with halitosis.

Patient ID Before Use After Use

* For ten subjects (Patient ID numbers 1, 11, 17, 18, 20, 23, 24, JJS, LSH, and UKJ), the amount of CTLSH in the breadth samples before use and after use was below the detection limit

Example 13: Effects of Chewable Gum Compositions on Bacterial Plaque With poor oral hygiene, food debris and dental bacterial plaque can accumulate on the teeth and tongue, and cause caries and periodontal diseases like gingivitis and periodontitis.

In order to determine the effects of chewable gum compositions on bacterial plaque build-up, bacterial plaque levels were analyzed in a human subject (tested on different days) before and after use of a chewable gum composition according to an embodiment of the invention in comparison with a commercially available chewing gum product in two different experiments.

In a first experiment, the chewable gum composition was prepared by heating and blending the commercially available chewing gum product with microcrystalline cellulose (“MCC”) (M101) (Ming Tai Chemical Co., Taiwan) in a weight ratio of 88:12 (12 wt% MCC). The resulting composition was cooled and shaped for use, and compared against the commercially available chewing gum product.

In a second experiment, a chewable gum composition prepared as Batch 1 (Example 2) was used, and compared against the same commercially available chewing gum product used in the first experiment.

Before administration, bacterial plaque build-up was visualized by rinsing the subject’s mouth with IC-Disclosing Solution to stain any plaque deposits with a red color. Photographs of the initial stain pattern observed for the subject “before use” is shown at the left side of Fig. 1 A and IB (first experiment) and Fig. 2A and 2B (second experiment). In the first experiment the subject chewed either 5.4 g of regular chewing gum (Fig.

1 A), or 6.0 g of the chewable gum composition described above (Fig. IB), for 20 minutes. In the second experiment the subject chewed either 5.4 g of regular chewing gum (Fig. 2A), or 6.0 g of the chewable gum composition (Fig. 2B) according to the invention, for 20 minutes. Remaining bacterial plaque levels were then assessed. In each experiment, after chewing ordinary chewing gum, the subject retained a large residual plaque build-up after 20 minutes of chewing (see Fig. 1 A, Fig. 2A, “after use”). Surprisingly, after chewing the chewable gum composition according to embodiments of the invention, the subject exhibited a significant reduction in the amount of stained bacterial plaque (see Fig. IB, Fig. 2B, “after use”). A side-by-side comparison of the stain patterns after use of each gum in the first experiment is shown in Fig. 1C, for the right side, center, and left side of the subject’s teeth. These results indicate that the present chewable gum compositions are effective to reduce or eliminate bacterial plaque after 20 minutes of chewing.
