Definitions
- the instant disclosure relates to cosmetic compositions providing improved penetration, and particularly to cosmetic compositions providing improved penetration without the use of common penetration enhancers. Additionally, aspects of the disclosure relate to methods for treating damaged skin with cosmetic compositions.
- 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

- 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.

In addition to reducing the shine or oiliness, mattifying agents can contribute to the overall texture and thickness of a cosmetic composition. Mattifying agents are often (but not always) particulate material or powders. Cosmetic compositions containing mattifying agents may be characterized by means of the following protocol.
- the test composition is spread out at a rate of 2 mg/cm 2 on a contrast card (Pruf badge type 24/5-250 cm 2 sold by the company Erichsen) using a mechanical film spreader.
- the composition is then dried overnight at a temperature of 37°C prior to measurement of its reflection using a gonioreflectometer sold by the company Micromodule.
- the intensity reflected specularly at 30° (R) and scattered at 90° (D) are successively measured.
- the result obtained is the ratio R between the specular reflection and the diffuse reflection.
- the value of R is proportionately smaller the greater the mattifying effect afforded by the filler.

Description
TITLE
COSMETIC COMPOSITION FOR IMPROVED PENETRATION
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims benefit of U.S. Application Serial No. 16/916,569, filed June 30, 2020, and French Patent Application No. 2009056, filed September ?,
2020, which are incorporated herein by reference in their entirety.
FIELD OF THE DISCLOSURE
The instant disclosure relates to cosmetic compositions providing improved penetration, and particularly to cosmetic compositions providing improved penetration without the use of common penetration enhancers. Additionally, aspects of the disclosure relate to methods for treating damaged skin with cosmetic compositions.
BACKGROUND OF THE DISCLOSURE
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.
SUMMARY OF THE DISCLOSURE
The instant disclosure relates to cosmetic compositions providing improved penetration of desired skin active agents into adult human skin. The inventors discovered that certain amounts and combinations of ingredients enable cosmetic compositions to provide improved penetration of desired skin active agents without the use of common penetration enhancers.
Cosmetic compositions according to an aspect of the disclosure typically include:
(a) about 0.1 to about 10 wt.% of C-glycoside;
(b) about 0.1 to about 5 wt.% of polyglyceryl-3 methylglucose distearate;

DETAILED DESCRIPTION OF THE DISCLOSURE
The present disclosure relates to cosmetic compositions providing improved penetration of desired skin active agents into adult human skin. As noted above, the inventors discovered that certain amounts and combinations of ingredients enable cosmetic compositions to provide improved penetration of desired skin active agents without the use of common penetration enhancers.
Cosmetic compositions according to an aspect of the disclosure typically include:
(a) about 0.1 to about 10 wt.% of C-glycoside;
(b) about 0.1 to about 5 wt.% of polyglyceryl-3 methylglucose distearate;
(c) about 0.1 to about 5 wt.% of sodium polyacrylate; and
(d) water, wherein the cosmetic composition is an oil-in-water emulsion, and all weight percentages are based on the total weight of the cosmetic composition.
In some cases, the cosmetic composition achieves the improved penetration of skin active agents into adult human skin. For example, the cosmetic compositions may achieve penetration of the skin active agent into the epidermis and dermis of skin. In some cases, the cosmetic composition may obtain about 2 pg/cm2 or more, 2.1 pg/cm2 or more, 2.2 pg/cm2 or more, 2.3 pg/cm2 or more, 2.4 pg/cm2 or more,
2.5 pg/cm2 or more, 2.6 pg/cm2 or more, 2.7 pg/cm2 or more, 2.8 pg/cm2 or more,
2.9 pg/cm2 or more, 3 pg/cm2 or more of skin active agent in the epidermis and dermis of human skin. In certain embodiments, the cosmetic compositions obtain
the improved penetration of skin active agents without the use of penetration enhancers.
Some therapeutic or cosmetic compositions achieve epidermal penetration by using a skin penetration enhancing carrier or vehicle. Such carrier or vehicles (which are compounds or mixtures of compounds) are often described as "penetration enhancers" or "skin enhancers." Typical penetration enhancers, which may be optionally excluded from the cosmetic composition, include sulphoxides (such as dimethylsulphoxide, DMSO), azones (e.g., laurocapram), pyrrolidones, (for example 2-pyrrolidone, 2P), alcohols and alkanols (ethanol, or decanol), surfactants (also common in dosage forms) and terpenes. Some penetration enhancers are capable of inserting between the hydrophobic tails of the bilayer, thus disturbing their packing, increasing their fluidity and, subsequently, leading to easier diffusion of lipid-like penetrants. The inventors surprisingly discovered that certain cosmetic compositions according to the disclosure provided improved penetration of skin active agents into adult human skin without necessitating the use of certain penetration enhancers. Nevertheless, in some cases, it may be desirable to include penetration enhancers, such as those discussed herein.
In some cases, the cosmetic composition has 5 wt.% or less, 4 wt.% or less, 3 wt.% or less, 2 wt.% or less, or 1 wt.% or less of any one of the foregoing penetration enhancers. In at least one instance, the cosmetic composition is free of or essentially free of any one of the foregoing penetration enhances. Additionally or alternatively, the cosmetic composition may have about 5 wt.% or less, 4 wt.% or less, 3 wt.% or less, 2 wt.% or less, or 1 wt.% or less of a total amount of penetration enhancers. For instance, the cosmetic composition may be free of or essentially free of penetration enhancers.
The cosmetic composition are generally formulated as an emulsion.
Typically, the cosmetic compositions are formulated to be oil-in-water emulsions, with the fatty phase emulsified in the hydrophilic phase. However, in some instances, the cosmetic compositions may be formulated to have a hydrophilic phase (e.g., alcohols, glycols, polyols, etc.) emulsified in the fatty phase. The cosmetic composition may be formulated, in some cases, to be lotions, serums, creams, sprays or any other suitable form of product.
Additionally, 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 and/or 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.
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, a gel, a cream, a spray, etc.).

Mattifying agents (also referred to as “mattifying fillers”) refer to material that gives the complexion more transparency and a hazy effect and provides skin with a natural and desireable appearance, without conferring on it a greasy, gleaming and shiny appearance. To do this, these materials are often absorbent fillers such as talc, silica, kaolin or fillers having light scattering optical properties, which properties are known under the name "soft focus" effect. In addition to reducing the shine or oiliness, mattifying agents can contribute to the overall texture and thickness of a cosmetic composition. Mattifying agents are often (but not always) particulate material or powders.
Cosmetic compositions containing mattifying agents may be characterized by means of the following protocol. The test composition is spread out at a rate of 2 mg/cm2 on a contrast card (Prufkarte type 24/5-250 cm2 sold by the company Erichsen) using a mechanical film spreader. The composition is then dried overnight at a temperature of 37°C prior to measurement of its reflection using a gonioreflectometer sold by the company Micromodule. The intensity reflected specularly at 30° (R) and scattered at 90° (D) are successively measured. The result obtained is the ratio R between the specular reflection and the diffuse reflection. The value of R is proportionately smaller the greater the mattifying effect afforded by the filler. A value of R of less than or equal to 2 generally indicates a mattifying effect. The mattifying agents according to the instant disclosure include those which, preferably at a content of 5% in a cosmetic composition, give a value of R of less than 1.5 and preferably less than 1.

These compounds may be isolated from natural sources, prepared by synthetic means, or mixtures thereof. Tocotrienol-enriched vitamin E preparations may be obtained by fractionating vitamin E preparations to remove a portion of tocopherols and recover a preparation more highly concentrated in tocotrienol. Useful tocotrienols are natural products isolated, for example, from wheat germ oil, grain, or palm oil using high
performance liquid chromatography, or isolated by alcohol extraction and/or molecular distillation from barley, brewer's grain or oats. As used herein, the term "tocotrienols" includes tocotrienol-rich-fractions obtained from these natural products as well as the pure compounds. The increased glutathione peroxidase activity protects the skin from oxidative damage.
In addition, carotenoids, particularly the xanthophyll type, are also useful antioxidants that can be used.

The amount of nonionic emulsifier other than polyglyceryl-3 methylglucose distearate may be about 0.1 to 20 wt.%, about 0.1 to about 18 wt.%, about 0.1 to about 16 wt.%, about 0.1 to about 14 wt.%, about 0.1 to about 12 wt.%, about 0.1 to about 10 wt.%, about 0.1 to about 8 wt.%, about 0.1 to about 7 wt.%, about 0.1 to about 6 wt.%, about 0.1 to about 5 wt.%; about 1 to about 20 wt.%, about 1 to about 18 wt.%, about 1 to about 16 wt.%,
about 1 to about 14 wt.%, about 1 to about 12 wt.%, about 1 to about 10 wt.%, about 1 to about 8 wt.%, about 1 to about 7 wt.%, about 1 to about 6 wt.%, about 1 to about 5 wt.%; about 4 to about 20 wt.%, about 4 to about 18 wt.%, about 4 to about 16 wt.%, about 4 to about 14 wt.%, about 4 to about 12 wt.%, about 4 to about 10 wt.%, about 4 to about 8 wt.%, or about 4 to about 7 wt.%, including all ranges and sub-ranges therebetween, based on the total weight of the cosmetic composition.
Emulsifiers are, typically, used to incorporate the oil and/or fatty compounds into a hydrophilic medium, such as an aqueous medium, to form oil-in-water emulsions. In some instances, however, the emulsifiers may be used to incorporate a hydrophilic phase (e.g., aqueous medium) into an oil or fatty phase to form a water-in-oil emulsion. The cosmetic compositions includes one or more nonionic emulsifiers. Additional emulsifiers, however, can also be included (or excluded), such as amphoteric, anionic, and/or cationic emulsifiers.
For O/W emulsions, examples of emulsifiers that may be mentioned include nonionic emulsifiers such as oxyalkylenated (more particularly polyoxyethylenated) fatty acid esters of glycerol; oxyalkylenated fatty acid esters of sorbitan; oxyalkylenated (oxyethylenated and/or oxypropylenated) fatty acid esters; oxyalkylenated (oxyethylenated and/or oxypropylenated) fatty alcohol ethers; sugar esters such as sucrose stearate; and mixtures thereof. A more exhaustive but non limiting list of useful nonionic emulsifiers is provided later, under the heading “Nonionic Emulsifiers.”
In some cases, the cosmetic compositions containing natural oils include two or more nonionic emulsifiers. In particular, one or more nonionic emulsifier having an HLB of 10 or higher and one or more nonionic emulsifiers having an HLB of 5 or less. The total amount of these emulsifiers can be such that the final HLB of the hair-treatment composition is within +/- 0.5 of the HLB of the natural oil in the cosmetic composition. This typically results in the final HLB of the emulsified natural oil in the hair-treatment composition ranging from about 6 to about 8.
Examples of emulsifiers that may be mentioned include nonionic emulsifiers such as oxyalkylenated (more particularly polyoxyethylenated) fatty acid esters of glycerol; oxyalkylenated fatty acid esters of sorbitan; oxyalkylenated (oxyethylenated
and/or oxypropylenated) fatty acid esters; oxyalkylenated (oxyethylenated and/or oxypropylenated) fatty alcohol ethers; sugar esters such as sucrose stearate; and mixtures thereof.
Non-limiting examples of nonionic emulsifiers include polyglyeryl-based emulsifiers, polyol esters, glycerol ethers, oxyethylenated ethers, oxypropylenated ethers, ethylene glycol polymers, sorbitan esters, polysorbate, and mixtures thereof.
In some instances, the one or more nonionic emulsifier selected from polyglyceryl 10-stearate, polyglyceryl-3-caprate, polyglyceryl-3-diisostearate, polyglyceryl-3 methylglucose distearate, or mixtures thereof. pH Adiuster(s)
The cosmetic composition may include one or more pH adjusters to increase or decrease the overall pH of the cosmetic composition. For example, one or more acids may be included to decrease the pH of the cosmetic composition. Examples of suitable acids for decreasing the pH of the cosmetic composition include, but are not limited to, citric acid, acetic acid, and the like. The cosmetic composition may include one or more bases, such as sodium hydroxide, potassium hydroxide and the like, to decrease the pH of the cosmetic composition. Additional or alternative acids and bases that are suitable for adjusting the pH of the cosmetic composition are readily known to one of ordinary skill in the art.
The cosmetic composition may, desirably, have a pH of about 4 to about 7, preferably about 4.5 to about 6.5 or about 5.5 to about 6.5. In one instance, the pH of the cosmetic composition is 6 or about 6. The amount of the pH adjuster in the cosmetic composition may be based on the desired pH of the final cosmetic composition and/or product. For example, the total amount of the pH adjuster may range from about 0.05 to about 20 wt.%, based on the total weight of the composition. In some instances, the total amount of pH adjuster is from about 0.05 to about 15 wt.%, about 0.5 to about 10 wt.%, about 1 to about 5 wt.%, about 1 .5 to about 4 wt.%, or about 2.0 to about 3 wt.%, including ranges and sub-ranges therebetween, based on the total weight of the composition.
Water
The total amount of water in the cosmetic composition can vary, but is typically about 50 to about 95 wt.%, based on the total weight of the cosmetic composition. In some instances, total amount of water is about 50 to about 90 wt.%, about 50 to about 85 wt.%, about 50 to about 80 wt.%; about 55 to about 95 wt.%, about 55 to about 90 wt.%, about 55 to about 85 wt.%, about 55 to about 80 wt.%; about 60 to about 95 wt.%, about 60 to about 90 wt.%, about 60 to about 85 wt.%, about 60 to about 80 wt.%; about 65 to about 95 wt.%, about 65 to about 90 wt.%, about 65 to about 85 wt.%, or about 65 to about 80 wt.%; about 70 to about 95 wt.%, about 70 to about 90 wt.%, about 70 to about 85 wt.%, about 70 to about 80 wt.%, including ranges and subranges therebetween, based on the total weight of the cosmetic composition.
Methods of Production
The instant disclosure also relates to methods or processes for making/manufacturing the cosmetic compositions described herein. It also encompasses the products prepared by these methods or processes.
A process for making certain embodiments of the cosmetic composition includes the formation of an oil phase and the formation of a separate aqueous phase (containing water), both phases are heated and combined while warm. Each phase may be heated to the same temperature or may be heated to different temperatures.
The thickening agents may be added to the aqueous phase of the cosmetic compositions. In some instances, however, the one or more emulsifiers and/or the thicken agents are added to the oil phase. Additionally or alternatively, thickening agents may be added post-emulsification — for instance, ammonium polyacryloydldimethyl taurate may be added post-emulsification.
After combining the oil phase and the aqueous phase to form an emulsion, the composition is typically allowed to cool. Additional components may be added during the time of emulsification or after. For example, certain fragrances, colorings, exfoliants, active ingredients, etc., may be added to the aqueous phase, the fatty phase, or after emulsification.
Methods of Use
The instant disclosure also relates to methods of using the cosmetic compositions described herein. For example, the cosmetic compositions can be used in a method that comprises applying the cosmetic compositions to the skin of humans. In some cases, the composition is applied to the face. Furthermore, the cosmetic composition can be used in methods for treating and/or 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 applies 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
The following examples are provided primary for the purpose of elucidating the benefits achieved by embodiments of the disclosure. The examples serve to illustrate the technology without necessarily being limiting in nature.
Example 1
Example 2
The penetration of Example Compositions A were evaluated in vitro by applying samples of Example Composition A to Glass Franz diffusion cells. Samples of Example Composition A were applied to applied to 3 porcine skin samples from 3 different donors. The porcine skin samples were full-thickness porcine skin obtained from the flank. Approximately, 5 mg/cm2 of Example Composition A was applied to a surface area of 2 cm2 of each porcine skin sample. The diffusion cells were filled with 3 ml_ of a receptor fluid, which was a saline solution having 0.9 wt.% of NaCI. The porcine skin samples of diffusion cells were maintained at a temperature of 32°C for 16 hours.
The porcine skin samples from the diffusion cells were washed with a 0.6 ml_ solution containing 5 wt.% of lauryl ether sulfate and soft massaged for 30 seconds using a half cotton bud. Subsequently, the porcine skin samples were washed using 0.6 ml_ of a solution containing 5 wt.% of lauryl ether sulfate by aspirating and dispensing the solution several times with a pipette. The porcine skin samples were then washed three times by aspirating and dispensing with a pipette 0.6 ml_ of water. After each of the foregoing washing steps, the respective solution or water was removed using a pipette. The porcine skin samples were dried using two half cotton buds after the washing steps were completed.
Tape-stripping was then performed on the porcine skin samples using adhesive DSquame™ tape, which was commercially available from Clinical & Derm. Specifically, 30 pieces of tape stripping (10 pieces obtained from each donor of porcine skin samples). Using a LC-MSMS device, the amount of Example Composition A that penetrated into epidermis, dermis (epd), and receptor fluid was determined to be an average amount of about 2.2 pg/cm2 of hydroxypropyl tetrahydropyrantriol.
The term “I NCI” 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.
In some instances, the cosmetic compositions of the present disclosure may be substantially free of non-incidental amounts of the ingredient(s) or compound(s) described herein. A non-incidental amount of an ingredient or compound is the amount of that ingredient or compound that is added into the cosmetic composition by itself. For example, a cosmetic composition may be substantially free of a non incidental amount of an ingredient or compound, although such ingredient(s) or compound(s) may be present as part of a raw material that is included as a blend of two or more compounds.
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, tocopherol may be characterized as both a skin active agent and a preservative. If a particular composition includes both a skin active agent and a preservative, steareth- 20 will serve only as the skin active agent or only as the preservative (tocopherol does not serve as both the skin active agent and preservative).
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 hair on a user’s head and/or body.
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 silicones.
