This application claims the benefit of priority from Chinese National Application No. 202211694961.8, filed Dec. 28, 2022, the contents of which are hereby incorporated herein by reference in their entirety.
The present disclosure relates to oral care compositions and methods for the same, specifically, to oral care compositions having a unique, multicolored pattern and methods for the same.
Aesthetic effects are known to play an important role in consumer acceptance of oral care products, such as, dentifrice or toothpaste products. These aesthetic effects allow consumers to distinguish particular products in the marketplace and to identify products having desirable, pleasing, and unique properties versus competitor products. Aesthetic effects also promote the consumer's recognition and repeated use of the product. Contrasting colored stripes or speckles are often utilized in dentifrice products to achieve these aesthetic effects. For example, these colored stripes or speckles provide an aesthetic effect that the consumer finds pleasing and promote product recognition. While incorporating colored stripes or speckles into conventional oral care products have proven to be effective for providing these aesthetic effects, the widespread use thereof has made the colored stripes and speckles commonplace; and thus, decreased the overall aesthetic effects.
What is needed, then, are improved oral care products having a unique, multicolored pattern and methods for the same.

Further areas of applicability of the present disclosure will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples, while indicating some typical aspects of the disclosure, are intended for purposes of illustration only and are not intended to limit the scope of the disclosure.
The following description of various typical aspect(s) is merely exemplary in nature and is in no way intended to limit the disclosure, its application, or uses.
As used throughout this disclosure, ranges are used as shorthand for describing each and every value that is within the range. It should be appreciated and understood that the description in a range format is merely for convenience and brevity and should not be construed as an inflexible limitation on the scope of any embodiments or implementations disclosed herein. Accordingly, the disclosed range should be construed to have specifically disclosed all the possible subranges as well as individual numerical values within that range. As such, any value within the range may be selected as the terminus of the range. For example, description of a range such as from 1 to 5 should be considered to have specifically disclosed subranges such as from 1.5 to 3, from 1 to 4.5, from 2 to 5, from 3.1 to 5, etc., as well as individual numbers within that range, for example, 1, 2, 3, 3.2, 4, 5, etc. This applies regardless of the breadth of the range.
Unless otherwise specified, all percentages and amounts expressed herein and elsewhere in the specification should be understood to refer to percentages by weight. The amounts given are based on the active weight of the material.
Additionally, all numerical values are “about” or “approximately” the indicated value, and take into account experimental error and variations that would be expected by a person having ordinary skill in the art. It should be appreciated that all numerical values and ranges disclosed herein are approximate values and ranges, whether “about” is used in conjunction therewith. It should also be appreciated that the term “about,” as used herein, in conjunction with a numeral refers to a value that may be +0.01% (inclusive), +0.1% (inclusive), +0.5% (inclusive), +1% (inclusive) of that numeral, +2% (inclusive) of that numeral, +3% (inclusive) of that numeral, +5% (inclusive) of that numeral, +10% (inclusive) of that numeral, or +15% (inclusive) of that numeral. It should further be appreciated that when a numerical range is disclosed herein, any numerical value falling within the range is also specifically disclosed.
As used herein, “free” or “substantially free” of a material may refer to a composition, component, or phase where the material is present in an amount of less than 10.0 wt %, less than 5.0 wt %, less than 3.0 wt %, less than 1.0 wt %, less than 0.1 wt %, less than 0.05 wt %, less than 0.01 wt %, less than 0.005 wt %, or less than 0.0001 wt % based on a total weight of the composition, component, or phase.
All references cited herein are hereby incorporated by reference in their entireties. In the event of a conflict in a definition in the present disclosure and that of a cited reference, the present disclosure controls.
Compositions disclosed herein may be or include an oral care product or an oral care composition thereof. For example, the composition may be an oral care product including the oral care composition, or the oral care composition thereof. Illustrative oral care products or oral care compositions may be or include, but are not limited to, a toothpaste (dentifrice), a prophylactic paste, a tooth gel (e.g., a whitening gel), or the like. In an exemplary implementation, the oral care products or the oral care composition disclosed herein is a dentifrice or toothpaste. For example, the oral care composition disclosed herein may be a toothpaste having a multicolored pattern, such as a unique, multicolored pattern that maintains the pattern in a vessel (e.g., bottle). As further disclosed herein, the oral care composition may maintain the unique, multicolored pattern in the vessel even while dispensing the composition from the vessel (e.g., pump bottle).
The oral care composition may include an orally acceptable vehicle, one or more abrasives or abrasive compounds, one or more thickening agents, a plurality of colorants, or a combination thereof. The oral care composition includes at least a first portion and a second portion, wherein the first portion includes a first colorant, and the second portion includes a second colorant. It should be appreciated that the oral care composition may also include a third or additional portions, each of which may include a different respective colorant. Each of the portions and the respective colorants thereof may provide or facilitate the formation of oral care compositions having or exhibiting a unique, multicolored pattern. As used herein, the term or expression “multicolor” or “multicolored” may refer to a substance or composition having a plurality of portions, each of the plurality of portions having a different color, different shades of the same color, different hues of the same color, or the like.
In at least one implementation, the oral care composition may have or exhibit a multicolored pattern of the colorants, wherein the respective colorants are at least substantially non-bleeding, non-diffusing, non-blurring, or otherwise non-mixing. For example, the colorant of the first portion of the oral care composition exhibits minimal, substantially none, or no bleeding, blurring, or otherwise mixing with the colorant of the second or another portion of the oral care composition. In another example, the first colorant of the first portion of the oral care composition exhibits minimal, substantially none, or no diffusion into the second portion of the oral care composition including the second colorant. Without being bound by theory, it is believed that the suppression of bleeding, diffusion, or mixing of the first colorant in the first portion into the second colorant of the second portion may be provided, at least in part, by the combination of ingredients/components of the composition. In at least one implementation, the suppression of bleeding, diffusion, or mixing of the first colorant in the first portion into the second colorant of the second portion may be provided by the combination of the thickening agents, the abrasives, the orally acceptable vehicle and/or a component thereof, or a combination thereof. For example, the suppression of bleeding, diffusion, or mixing of the first colorant in the first portion into the second colorant of the second portion may be provided by a matrix formed by a combination of the thickening agents, the abrasives, the orally acceptable vehicle and/or a component thereof, or a combination thereof. The matrix may prevent or inhibit the respective colorant in one portion of the oral care composition from diffusing into or mixing with another portion of the oral care composition. In a preferred implementation, the matrix is formed from a combination of the thickening agents, the abrasives, the orally acceptable vehicle and/or a component thereof, or a combination thereof. For example, the matrix may be formed from a combination of abrasive silica, one or more thickening agents, including but not limited to, a silica thickener or thickener silica, xanthan gum, or a combination thereof, one or more humectants of the orally acceptable vehicle, including but not limited to, glycerin, polyethylene glycol, or a combination thereof, one or more surfactants of the orally acceptable vehicle, including but not limited to, sodium lauryl sulfate. In an exemplary implementation, the matrix is formed from a combination of abrasive silica, a thickener silica, xanthan gum, glycerin, polyethylene glycol, and sodium lauryl sulfate, each in an amount and/or ratio effective to form the matrix. The abrasive silica may be present in an amount of from about 6 wt % to about 10 wt %, about 7 wt % to about 9 wt %, or about 8 wt %, based on the total weight of the oral care composition. The thickener silica may be present in an amount of from about 2 wt % to about 8 wt %, about 3 wt % to about 7 wt %, about 4 wt % to about 6 wt %, or about 5 wt %. A weight ratio of the abrasive silica to the thickener silica may be from about 1:1 to about 2:1, about 1.2:1 to about 1.8:1, about 1.4:1 to about 1.7:1, about 1.5:1 to about 1.6:1, or about 1.6:1. The xanthan gum may be present in an amount of from greater than 0 wt % to about 2 wt %, about 0.1 wt % to about 1.5 wt %, about 0.2 wt % to about 1 wt %, about 0.3 wt % to about 0.7 wt %, or about 0.4 wt % to about 0.6 wt %, or about 0.4 wt % to about 0.5 wt %. The glycerin may be present in an amount of from about 45 wt % to about 65 wt %, about 50 wt % to about 60 wt %, about 55 wt % to about 57 wt %, or about 56 wt %. The polyethylene glycol may be present in an amount of from about 1 wt % to about 5 wt %, about 2 wt % to about 4 wt %, or about 3 wt %. The sodium lauryl sulfate may be present in an amount of from greater than 0 wt % to about 4 wt %, about 1 wt % to about 3 wt %, or about 2 wt %.
As disclosed herein, the multicolored oral care composition may be provided by the colorant of the first portion of the oral care composition and the colorant of the second portion of the oral care composition. The first portion and the second portion of the oral care composition are in contact with one another, but are arranged or disposed in a random, unique pattern. As such, the first portion and the second portion of the oral care compositions are not disposed in parallel layers. For example, the first and second portions of the oral care composition are not disposed in ordered horizontal or vertical layers.
The first and second portions of the oral care composition may include the same or substantially the same composition (e.g., base composition) except for the respective colorants thereof. For example, the first and second portions of the oral care composition may include the same or substantially the same orally acceptable vehicle, abrasives or abrasive compounds, thickening agents, or a combination thereof, but may further include different colorants.
The oral care products and oral care compositions disclosed herein may be disposed in any dispensing means. The dispensing means may be at least partially transparent such that the unique, multicolored pattern of the oral care composition is visible to the consumer. Illustrative dispensing means may be or include, but are not limited to, a collapsible tube, a pump bottle, or any other vessel known in the art for dispensing oral care compositions, especially dentifrice compositions. In a preferred implementation, the oral care products or the oral care compositions utilize a pump bottle capable of or configured to dispense the oral care product or the oral care composition by drawing the oral care product or the oral care composition from the bottom of the bottle. It should be appreciated that the matrix formed in the oral care composition allows the oral care composition to maintain its unique multicolored pattern as the pump bottle dispenses the oral care composition. It should be further appreciated that a rigidity of the pump bottle may allow the composition to maintain the unique multicolored pattern. For example, utilizing a collapsible tube would require the tube to be compressed to dispense the oral care composition, and the compression of the tube may disrupt or destroy the unique multicolored pattern formed during manufacture.
The oral care product or the oral care composition thereof may include one or more abrasives or abrasive compounds. As used herein, the term “abrasive” may refer to materials commonly referred to as “polishing agents.” The one or more abrasives may be mixed, combined, dispersed, suspended, or otherwise contacted with the orally acceptable vehicle. In at least one implementation, the oral care product or the whitening composition thereof includes a single abrasive. In another implementation, the oral care product or the whitening composition thereof includes a mixture or combination of at least two abrasives. Illustrative abrasives may be or include, but are not limited to, metaphosphate compounds, phosphate salts (e.g., insoluble phosphate salts), such as sodium metaphosphate, potassium metaphosphate, calcium pyrophosphate, magnesium orthophosphate, trimagnesium orthophosphate, tricalcium phosphate, dicalcium phosphate dihydrate, anhydrous dicalcium phosphate, calcium carbonate, magnesium carbonate, hydrated alumina, abrasive silicas, silica, silicates, zirconium silicate, aluminum silicate, calcined aluminum silicate, polymethyl methacrylate, or the like, or a combination thereof. In an exemplary implementation, the abrasives include at least the silica abrasives, such as those available under the trade designation ZEODENT® 115, which are commercially available from Evonic Industries, AG of Essen Germany.

All ingredients for use in the compositions described herein should be orally acceptable. As used herein, “orally acceptable” may refer any ingredient that is present in a composition as described in an amount and form which does not render the composition unsafe for use in the oral cavity.
The examples and other implementations described herein are exemplary and not intended to be limiting in describing the full scope of compositions and methods of this disclosure. Equivalent changes, modifications and variations of specific implementations, materials, compositions and methods may be made within the scope of the present disclosure, with substantially similar results.
Exemplary oral care compositions having a multicolored pattern were prepared by preparing a base composition without any colorants, according to Table 1. A first portion of the base composition was combined with a first water immiscible pigment and a second portion of the base composition was combined with a second water immiscible pigment.
Each of the first and second portions of the base composition including their respective pigment was maintained separately until they were charged or disposed into a vessel (i.e., bottle). The first portion of the base composition including the first pigment was disposed into the vessel via a first nozzle, and the second portion of the base composition including the second pigment was disposed into the vessel via a second nozzle. It was observed that the combination of the abrasive silica, the thickener silica, the xanthan gum, glycerin, polyethylene glycol, and the surfactant, facilitated the formation of a matrix to keep the respective colorant/pigment in one portion from bleeding or blending into another portion of the oral care composition. The first and second portions were charged or disposed into the vessel at the same time while gently agitating or swirling the bottle. It was surprisingly and unexpectedly discovered that oral care compositions having unique and random multicolored patterns were able to be obtained by varying the ratio of each of the filling nozzles and the speed of agitating/swirling the bottle. It was further surprisingly and unexpectedly discovered that the general appearance or aesthetic effect of the multicolored pattern may be consistently provided in each sample (e.g., bottle) by controlling or maintaining the rate of dispensing the first portion into the vessel, the rate of dispensing the second portion into the vessel, and the rate of agitating the vessel while dispensing the portions into the vessel. It was also surprisingly and unexpectedly observed that the unique and random multicolored pattern formed in the oral care compositions were maintained with no color bleeding or diffusion observed. It was further surprisingly and unexpectedly discovered that the unique and random multicolored pattern formed in the oral care compositions upon manufacture were maintained with no color bleeding or diffusion under accelerated aging conditions, including stressed, relatively high temperature conditions. It was surprisingly and unexpectedly observed that the combination of the abrasive silica, the thickener silica, the xanthan gum, glycerin, polyethylene glycol, and the surfactant, facilitated the formation of a matrix to keep the respective colorant/pigment in one portion from bleeding or blending into another portion of the oral care composition.
It was observed that utilizing a pump to dispense the oral care composition allowed the composition and the matrix thereof to maintain the unique and random multicolored pattern within the bottle while concurrently delivering a plurality of colors through the nozzle of the pump. Particularly, the unique and random multicolored pattern formed in the bottle was maintained and merely shifted down as the pump dispensed the oral care composition from the bottom of the bottle. Conversely, it was observed that utilizing a collapsible tube altered or destroyed the unique multicolored pattern formed upon manufacture and/or result in the bleeding, blending, or diffusion of the colorant from one portion of the oral care composition with the colorant from another portion of the oral care composition.
The present disclosure has been described with reference to exemplary implementations. Although a limited number of implementations have been shown and described, it will be appreciated by those skilled in the art that changes may be made in these implementations without departing from the principles and spirit of the preceding detailed description. It is intended that the present disclosure be construed as including all such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
