Definitions
- the present disclosure relates to cosmetic compositions comprising high amounts of ascorbic acid (vitamin C), products containing the cosmetic compositions, and methods for treating skin using the cosmetic compositions.
- vitamin C ascorbic acid
- Skin acts as a natural barrier between internal and external environments and therefore plays an important role in vital biological functions such as protection against mechanical and chemical injury, microorganisms, and ultraviolet damage.
- the health and appearance of skin can deteriorate due to environmental factors, genetic makeup, nutrition, and sun exposure.
- UV radiation ultraviolet
- environmental pollution wind, heat, infrared radiation
- low humidity low humidity
- harsh surfactants abrasives
- Typical skin damage includes fine lines, wrinkling, hyperpigmentation, sallowness, sagging, dark under-eye circles, puffy eyes, enlarged pores, visible dead skin, i.e. , flaking, scaling, dryness, and roughness. Consumers desire to slow the gaining of skin damage and reduce the effects of aging, especially in the face and around the eyes. Radiant and clear skin appears youthful and is a sign of good health and vitality. Accordingly, there is an ongoing need for new and improved formulations that improve the health and visual appearance of skin.
- Vitamin C is a potent antioxidant that can be used topically in dermatology to treat and prevent changes associated with photoageing, hyperpigmentation, etc.
- Vitimin C is very unstable and difficult to formulate and deliver into the dermis.
- the instant disclosure relates to cosmetic compositions that are unique in comparison to conventional cosmetic compositions because they contain and deliver a high concentration of ascorbic acid. Ascorbic acid is very difficult to stabilize, and therefore pose unique formulations challenges.
- the inventors discovered that certain ingredients in specific amounts enables cosmetic compositions containing high level of ascorbic acid to be stable.

- the hydroxyacetophenone is present from about 0.1 to about 3 wt.% based on the total weight of the cosmetic composition.
- the chelating agent is chosen from Trisodium Ethylenediamine Disuccinate, Sodium Phytate, Tetrasodium Glutamate Diacetate, and mixture thereof. In one or more embodiments, the chelating agent is Trisodium Ethylenediamine Disuccinate. In one embodiment, the chelating agent is present from about 0.01 to about 1 wt.% based on the total weight of the cosmetic composition.
- the cosmetic composition may include one or more fatty compounds.
- suitable fatty compounds may include fatty alcohols, fatty acids, fatty esters, oils, waxes, derivatives thereof, and mixtures thereof.
- the one or more fatty ester may be chosen from ethoxylated fatty esters, sorbitan fatty esters, esters of stearates, esters of behenates, esters of arachidates, esters of palmitates, fatty acid esters of a sugar, and mixtures thereof.
- one or more fatty ester may be chosen from purcellin oil (cetearyl octanoate), isopropyl myristate, isopropyl palmitate, C12-C15 alkyl benzoate, 2- ethylphenyl benzoate, isopropyl lanolate, hexyl laurate, diisopropyl adipate, isononyl isononanoate, oleyl erucate, 2-ethylhexyl palmitate, isostearyl isostearate, diisopropyl sebacate, octanoates, decanoates or ricinoleates of alcohols or polyalcohols, hydroxylated esters, and pentaerythritol esters, and mixtures thereof.
- the one or more fatty compounds comprises isononyl isononanoate, caprylic/capric triglyceride, glycine so
- the oil phase may comprise from about 0.5 to about 20 wt.%, based on the total weight of the cosmetic composition.

COSMETIC COMPOSITION COMPRISING VITAMIN C
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims priority to U.S. Patent Application No. 17/329,742 filed May 25, 2021. This application also claims priority to French Patent Application No. 2108705, filed August 16, 2021.
FIELD OF THE INVENTION
The present disclosure relates to cosmetic compositions comprising high amounts of ascorbic acid (vitamin C), products containing the cosmetic compositions, and methods for treating skin using the cosmetic compositions.
BACKGROUND OF THE INVENTION
Skin acts as a natural barrier between internal and external environments and therefore plays an important role in vital biological functions such as protection against mechanical and chemical injury, microorganisms, and ultraviolet damage. The health and appearance of skin, however, can deteriorate due to environmental factors, genetic makeup, nutrition, and sun exposure.
Environmental pollution conditions are fast worsening and becoming more apparent in the daily life of consumers worldwide. The damage of pollution against human skin is also becoming more and more evident. Human skin is also subjected to a variety of insults by extrinsic factors such as ultraviolet (UV) radiation, environmental pollution, wind, heat, infrared radiation, low humidity, harsh surfactants, abrasives, etc. Recent studies suggest that in addition to UV radiation, other environmental factors contribute to the development of solar lentigines, particularly air pollution. Ultimately, these factors result in visible signs of skin damage including small brown patches on the skin, especially in the elderly.
Typical skin damage includes fine lines, wrinkling, hyperpigmentation, sallowness, sagging, dark under-eye circles, puffy eyes, enlarged pores, visible dead
skin, i.e. , flaking, scaling, dryness, and roughness. Consumers desire to slow the gaining of skin damage and reduce the effects of aging, especially in the face and around the eyes. Radiant and clear skin appears youthful and is a sign of good health and vitality. Accordingly, there is an ongoing need for new and improved formulations that improve the health and visual appearance of skin.
Vitamin C is a potent antioxidant that can be used topically in dermatology to treat and prevent changes associated with photoageing, hyperpigmentation, etc.
Vitimin C is very unstable and difficult to formulate and deliver into the dermis.
Research has been ongoing to develop stable compositions that deliver high amounts of ascorbic acid to the skin.
SUMMARY OF THE DISCLOSURE
The instant disclosure relates to cosmetic compositions that are unique in comparison to conventional cosmetic compositions because they contain and deliver a high concentration of ascorbic acid. Ascorbic acid is very difficult to stabilize, and therefore pose unique formulations challenges.
The inventors discovered that certain ingredients in specific amounts enables cosmetic compositions containing high level of ascorbic acid to be stable.
While not wishing to be bound by any particular theory, the inventors believe that di-t-butyl pentaerythrityl tetrahydroxycinnamate, hydroxyacetophenone, and a chelating agent, in combination with other components of the compositions, contribute to the stability and effectiveness of the compositions. The cosmetic compositions typically include:
(a) from about 2 to about 20 wt.% of ascorbic acid;
(b) di-t-butyl pentaerythrityl tetrahydroxycinnamate;
(c) hydroxyacetophenone; and
(d) a chelating agent; and wherein the cosmetic composition is an oil-in-water emulsion, and all weight percentages are based on the total weight of the cosmetic composition.
The cosmetic compositions may be in the form of an emulsion, for example, an oil-in-water emulsion. In some embodiments, the cosmetic composition is in the form of an oil-in- water emulsion.
In some embodiments, the di-t-butyl pentaerythrityl tetrahydroxycinnamate is present from about 0.05 to about 0.5 wt.% based on the total weight of the cosmetic composition.
In one or more embodiments, the hydroxyacetophenone is present from about 0.1 to about 3 wt.% based on the total weight of the cosmetic composition.
In some embodiments, the chelating agent is chosen from Trisodium Ethylenediamine Disuccinate, Sodium Phytate, Tetrasodium Glutamate Diacetate, and mixture thereof. In one or more embodiments, the chelating agent is Trisodium Ethylenediamine Disuccinate. In one embodiment, the chelating agent is present from about 0.01 to about 1 wt.% based on the total weight of the cosmetic composition.
In some embodiments, the cosmetic composition may include one or more fatty compounds. Non-limiting examples of suitable fatty compounds may include fatty alcohols, fatty acids, fatty esters, oils, waxes, derivatives thereof, and mixtures thereof. In various embodiments, the one or more fatty ester may be chosen from ethoxylated fatty esters, sorbitan fatty esters, esters of stearates, esters of behenates, esters of arachidates, esters of palmitates, fatty acid esters of a sugar, and mixtures thereof. In one embodiment, one or more fatty ester may be chosen from purcellin oil (cetearyl octanoate), isopropyl myristate, isopropyl palmitate, C12-C15 alkyl benzoate, 2- ethylphenyl benzoate, isopropyl lanolate, hexyl laurate, diisopropyl adipate, isononyl isononanoate, oleyl erucate, 2-ethylhexyl palmitate, isostearyl isostearate, diisopropyl sebacate, octanoates, decanoates or ricinoleates of alcohols or polyalcohols, hydroxylated esters, and pentaerythritol esters, and mixtures thereof. In some embodiments, the one or more fatty compounds comprises isononyl isononanoate, caprylic/capric triglyceride, glycine soja (soybean) oil or mixtures thereof.
In some embodiment, the oil phase may comprise from about 0.5 to about 20 wt.%, based on the total weight of the cosmetic composition.
Additionally or alternatively, the cosmetic composition may include one or more polyols. In various embodiments, the one or more polyols are chosen from caprylyl glycol, pentylene glycol, butylene glycol, hexalyne glycol, glycerin, dipropylene glycol, propylene glycol, and mixtures thereof. In some cases, the cosmetic composition is free of tocopherol.
In accordance with another aspect of the disclosure, the cosmetic composition may include:
(a) from about 2 to about 20 wt.% of ascorbic acid;
(b) from about 0.05 to about 0.5 wt.% of di-t-butyl pentaerythrityl tetrahydroxycinnamate;
(c) from about 0.01 to about 3 wt. % of hydroxyacetophenone; and
(d) from about 0.01 to about 2 wt.% of a chelating agent chosen from Trisodium Ethylenediamine Disuccinate, Sodium Phytate, Tetrasodium Glutamate Diacetate; and wherein the cosmetic composition is an oil-in-water emulsion, and all weight percentages are based on the total weight of the cosmetic composition.
The cosmetic compositions are useful for treating skin, for example, the skin of the face and neck of a human. Thus, the instant disclosure relates to methods of treating the skin comprising application of the cosmetic composition of the instant disclosure to the skin. The cosmetic compositions are additionally useful in methods for treating skin dryness, repairing skin damage due to photoaging, and diminishing the appearance of wrinkles, dark spots, and uneven skin texture. The aforementioned methods may be non-therapeutic.
DETAILED DESCRIPTION OF THE DISCLOSURE
The present disclosure relates to stable cosmetic compositions that contain high amounts of ascorbic acid (vitamin C), and methods for treating skin using the cosmetic compositions. Ascorbic acid is a naturally occurring antioxidant. It is an enhancer of the biosynthesis of collagen, which is the protein that provides shape and firmness to the skin. Because ascorbic acid leads to higher production of collagen, wrinkling in skin is minimized. In addition, ascorbic acid can decrease age spots by reversing hyperpigmentation in skin cells to a certain extent by inhibiting tyrosinase activity.
The cosmetic compositions of the instant disclosure typically include:
(a) from about 2 to about 20 wt.% of ascorbic acid;
(b) di-t-butyl pentaerythrityl tetrahydroxycinnamate;
(c) hydroxyacetophenone; and
(d) a chelating agent; and wherein the cosmetic composition is an oil-in-water emulsion, and all weight percentages are based on the total weight of the cosmetic composition.
The cosmetic compositions are generally formulated as an emulsion. Typically, the cosmetic compositions are formulated to be oil-in-water emulsions.
In one embodiment, the composition is an oil-in-water emulsion. For example, the amount of oil phase may be from about 0.5, about 1 , about 1.5, about 2, about 2.5, about 3, about 3.5, about 4, about 5, about 6, about 7, about 8, about 9, about 10 to about 10, about 11, about 12, about 13, about 14, about 14.5, about 15, about 15.5, about 16, about 16.5, about 17, about 17.5, about 18, about 18.5, about 19, about 19.5, or about 20 wt.%, including ranges and sub-ranges there between, based on the total weight of the composition. Additionally or alternatively, the amount of oil phase may be 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 7, 8, 9, 10 to about 10, 11, 12, 13, 14, 14.5, 15, 15.5,
16, 16.5, 17, 17.5, 18, 18.5, 19, 19.5, or 20 wt.%, including ranges and sub-ranges there between, based on the total weight of the composition. In one embodiment, the
amount of oil phase may be 10% or about 10% of the total weight of the cosmetic composition.
As discussed above, it is believed that the di-t-butyl pentaerythrityl tetrahydroxycinnamate, hydroxyacetophenone and a chelating agent advantageously facilitate the stabilization of the ascorbic acid in the emulsion. The aqueous phase of the cosmetic composition may include an amount of ascorbic acid. For instance, a majority or essentially the entirety of ascorbic acid of the cosmetic composition may reside in the aqueous phase.
Suitable components, such as those listed below, may be included or excluded from the formulations for the cosmetic compositions depending on the specific combination of other components, the form of the cosmetic compositions, and/or the use of the formulation (e.g., a lotion, a serum, gel, cream, etc.).

Additionally or alternatively, the amount of ascorbic acid may be 2.0 wt.% to 20 wt.%, 2.5 wt.% to 20 wt.%, 3.5 wt.% to 20 wt.%, 4.5 wt.% to 20 wt.%, 5 wt.% to 15 wt.%, 6 wt.% to 14 wt.%, 7 wt.% to 13 wt.%, or 8 wt.% to 12 wt.% including ranges and sub-ranges there between, based on the total weight of the composition. Likewise, in some embodiments, the cosmetic composition may include an amount of ascorbic acid that is about 20 wt.%, about 19 wt.%, about 18 wt.%, about 17 wt.%, about 16 wt.%, about 15 wt.%, about 14 wt.%, about 13 wt.%, about 12 wt.%, about 11 wt.%, about 10 wt.%, about 9 wt.%,
about 8 wt.%, about 7 wt.%, about 6 wt.%, about 5 wt.%, about 4 wt.%, about 3 wt.%, about 2 wt.% or about 1 wt.%, based on the total weight of the composition. In one embodiment, the amount of ascorbic acid may be 10% or about 10% of the total weight of the cosmetic composition.
The ascorbic acid may be L-ascorbic acid, a mixture of L-ascorbic acid and R- ascorbic acid, and/or a racemic mixture. In one embodiment, the ascorbic acid comprises only L-ascorbic acid, essentially only L-ascorbic acid, and/or at least 75 wt.%, at least 85 wt.%, at least 90 wt.%, at least 95 wt.%, or at least 99 wt.% of L- ascorbic acid based on the total weight of ascorbic acid.

Furthermore, the cosmetic composition can be used in methods for treating dryness of the skin, repairing damage to skin (for example, damage from photoaging), and for diminishing the appearance of wrinkles, dark spots, and uneven skin texture of skin. The aforementioned methods are non-therapeutic.
The cosmetic composition may be applied once per day, twice per day, or more than once or twice per day. In some cases, the composition is applied in the evenings before bed. In other cases, the compositions are applied in the morning. In still other cases, the composition may be applied immediately after washing the skin. The compositions may be used once, or for a series of days, weeks, or months. For example, the compositions may be used daily for a period of 1 , 2, 3, 4, 5, 6, 7, 8 or more weeks, or months.
EXAMPLES
Implementation of the present disclosure is provided by way of the following examples. The following examples serve to elucidate aspects of the technology without being limiting in nature. Example 1
(Inventive Compositions)
Table 1
*% of Active ingredients
The Inventive Examples were prepared according to the procedure as follows:
Polymers in phase A1 were dispersed in water with agitation until a clear gel with no powder or lumps were formed. Then, components of phase A2 were added to the resultant gel with agitation with yield aqueous phase A. Phase A was then heated to about 75C. Separately, phases B and C were combined and heated to 75C until all materials melted, dispersed, and/or solubilized. Phases B and C were then added slowly to phase A with sitting and homogenization that continued until a fine emulsion
formed. The resultant formula was then cooled down. Upon reaching <30C, the components of phase D were added, followed by the components of phase E, with homogenization to combine. Finally, phase F was added and formula was homogenized. Process was complete when a fine emulsion with well-dispersed powder resulted, and batch reached about 25C.
Example 2
(Evaluation of Vitamin C chemical stability)
Inventive Examples 1 and 2 were formulated for purposed of containing high levels of actives, mainly high levels of pure Vitamin C. In order to evaluate the stability of the pure Vitamin C in the formulation, various antioxidants and chelators were tested in these emulsions (i.e. Comparative Examples). The inventive et comparative examples are presented in Table 2.
Table 2: Inventive and Comparative Examples
* % of Active ingredients
After formulation, each example formula was filled into an aluminum tube and chemical stability was observed. The analytical team metered the amount of vitamin C and it was measured over time by an analytical method. The results are presented in the table below.
Table 3: Vitamin C Chemical Stability
Table 3 above showed the evaluation of chemical stability of various antioxidants (AOX) and chelators in the representative formulation. Finished formulations in sealed aluminum tubes were placed in controlled chambers at 25C and 45C. A freshly made tube was also submitted to analysis to obtain the starting baseline active concentration (i.e. , TO). At 1 month (T1M) and 2 months (T2M) in each temperature controlled chamber, a tube of formula was submitted for quantitative active analysis. Initial (TOM) was then compared with aged sample at elevated temperature (T2M45C).
In the case of the Control Example that only contained a chelator (i.e., EDDS = Trisodium Ethylenediamine Disuccinate), it was observed that the Vitamin C was not very stable and that after T2M at 45°C, the percentage of Vitamin C remaining was about 77.43%. Then, different Antioxidants as well as different chelators were evaluated and demonstrated that all the Antioxidants and chelators were not equal. Inventive Ex. 1 and Inventive Ex. 2 exhibited the best stability for the Vitamin C, proving that the presence of Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate (i.e., Tinogard TT) associated with a chelator exhibited an improvement of Vit C stability. Additionally, when Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate (i.e., Tinogard TT) was kept in the formula, but hydroxyacetophenone and a chelator were removed, stability was poor (See Comp. Ex.1 and Comp. Ex. 2). Thus, the combination of Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate, hydroxyacetophenone, and a chelator were required to obtain high chemical stability.
In the Inventive Examples, pure Vitamin C was able to be stabilized with high chemical stability (>85%) even after 2 months at 45C. This was in contrast to other formulas that didn’t contain the combination of Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate, Hydroxyacetophenone and a chelating agent.
Table 4: Vitamin C Chemical Stability of Comparative Examples
In Table 4, Comparative Ex. 1 demonstrated that the combination of Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate, hydroxyacetophenone, and a chelator were required to obtain high chemical stability. It was also demonstrated with Comparative Ex. 2 that the presence of Vitamin E is not necessary in order to stabilize the high level of Vitamin C.
The term “INCI” is an abbreviation of International Nomenclature of Cosmetic Ingredients, which is a system of names provided by the International Nomenclature Committee of the Personal Care Products Council to describe personal care ingredients.
As used herein, all ranges provided are meant to include every specific range within, and combination of sub ranges between, the given ranges. Thus, a range from 1-5, includes specifically 1, 2, 3, 4 and 5, as well as sub ranges such as 2-5, 3-5, 2-3, 2- 4, 1-4, etc.
All components and elements positively set forth in this disclosure can be negatively excluded from the claims. In other words, the cosmetic compositions of the instant disclosure can be free or essentially free of all components and elements positively recited throughout the instant disclosure. Some of the various categories of components identified may overlap. In such cases where overlap may exist and the composition includes both components (or the
composition includes more than two components that overlap), an overlapping compound does not represent more than one component. For example, a fatty acid may be characterized as both a nonionic surfactant and a fatty compound. If a particular composition includes both a nonionic surfactant and a fatty compound, a single fatty acid will serve as only the nonionic surfactant or as only the fatty compound (the single fatty acid does not serve as both the nonionic surfactant and the fatty compound).
All publications and patent applications cited in this specification are herein incorporated by reference, and for any and all purposes, as if each individual publication or patent application were specifically and individually indicated to be incorporated by reference. In the event of an inconsistency between the present disclosure and any publications or patent application incorporated herein by reference, the present disclosure controls.
As used herein, the terms “comprising,” “having,” and “including” are used in their open, non-limiting sense.
The terms “a,” “an,” and “the” are understood to encompass the plural as well as the singular. Thus, the term “a mixture thereof” also relates to “mixtures thereof.” Throughout the disclosure, the term “a mixture thereof” is used, following a list of elements as shown in the following example where letters A-F represent the elements: “one or more elements selected from the group consisting of A, B, C, D, E, F, and a mixture thereof.” The term, “a mixture thereof” does not require that the mixture include all of A, B, C, D, E, and F (although all of A, B, C, D, E, and F may be included).
Rather, it indicates that a mixture of any two or more of A, B, C, D, E, and F can be included. In other words, it is equivalent to the phrase “one or more elements selected from the group consisting of A, B, C, D, E, F, and a mixture of any two or more of A, B,
C, D, E, and F.”
The expression “one or more” means “at least one” and thus includes individual components as well as mixtures/combinations.
Other than in the operating examples, or where otherwise indicated, all numbers expressing quantities of ingredients and/or reaction conditions may be modified in all instances by the term “about,” meaning within +/- 5% of the indicated number.
The term “treat” (and its grammatical variations) as used herein refers to the application of the compositions of the present disclosure onto the surface of keratinous substrates such as skin, in particular, the skin of the head, face, and neck.
The term “substantially free” or “essentially free” as used herein means that there is less than about 2% by weight of a specific material added to a composition, based on the total weight of the compositions. Nonetheless, the compositions may include less than about 1 wt.%, less than about 0.5 wt.%, less than about 0.1 wt.%, or none of the specified material. All of the components set forth herein may be optionally included or excluded from the compositions/method/kits. When excluded, the compositions/methods/kits may be free or essentially free of the component. For example, a particular composition may be free or essentially free of alkoxylated compounds, for example, ethoxylated thickeners and/or ethoxylated surfactants. Likewise, a particular composition may be free or essentially free of sulfates, such as sulfate surfactants.
While the instant disclosure has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes may be made, and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the instant disclosure without departing from the essential scope thereof. Therefore, it is intended that the instant disclosure is not limited to the particular embodiment disclosed as the best mode contemplated for carrying out this instant disclosure, but that the instant disclosure will include all embodiments falling within the scope of the appended claims.
