TITLE

COSMETIC COMPOSITION HAVING RETINOL

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims benefit of U.S. Application Serial No. 16/916,742, filed June 30, 2020, and French Patent Application No. 2009088, filed September 8,

2020, which are incorporated herein by reference in their entirety.

FIELD OF THE DISCLOSURE

The instant disclosure relates to cosmetic compositions providing improved retinol penetration. Additionally, the 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 present disclosure relates to cosmetic compositions having stabilized retinol, and particularly to cosmetic compositions providing improved penetration of retinol. The inventors discovered that certain components in specific amounts enables cosmetic compositions with improved penetration of retinol into adult human skin.

The cosmetic composition typically includes:

(a) about 0.01 to about 3 wt.% of retinol;

(b) about 0.1 to about 14 wt.% of sodium polyacrylate;

(c) about 0.2 to about 10 wt.% of one or more nonionic emulsifier; and

(d) about 0.5 to about 12 wt.% of a fatty phase, wherein the fatty phase comprises one or more fatty compounds; and

(e) 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.

The cosmetic composition may include about 0.3 to about 5 wt.% of sodium polyacrylate. The nonionic emulsifier may be chosen from 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 is chosen from polyglyceryl 10-stearate, polyglyceryl-3-caprate, polyglyceryl-3-diisostearate, polyglyceryl-3 methylglucose distearate, polysorbate 20, and mixtures thereof.

Suitable examples of fatty compounds that may incorporated into the cosmetic compostion include fatty alcohols, fatty acids, fatty esters, oils, waxes, derivatives thereof, and mixtures thereof. In certain instances, the 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 further instances, the fatty ester 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 fatty compounds may comprise isononyl isononanoate, caprylic/capric triglyceride, glycine soja (soybean) oil or mixtures thereof. In some instances, the cosmetic composition includes about 0.5 to about 5 wt.% of a fatty phase.

In some embodiments, the cosmetic composition further includes about 1 to about 35 wt.% of one or more water soluble solvent. The one or more water soluble solvent may be chosen from alkanediols, alcohols, organic solvents, polyols, and mixtures thereof. Non-limiting examples of polyols that may be incorporated into the cosmetic composition include butylene glycol, caprylyl glycol, or mixtures thereof.

Additionally or alternatively, the cosmetic composition may further include about 0.01 to about 10 wt.% of one or more thickening agent other than sodium polyacrylate. The one or more thickening agent other than sodium polyacrylate may be chosen from chosen from acrylates, acrylates copolymers, polyacrylamide, carbomer, gums, polysaccharides, and mixtures thereof. In at least one instance, the one or more thickener other than sodium polyacrylate comprises acrylates/beheneth-25 methacrylate copolymer, methyl methacrylate crosspolymer, or a mixture thereof.

The cosmetic composition may include encapsulated retinol in some cases. The capsules encapsulating the retinol may further include at least one of ferulic acid, hyaluronic acid, tocopherol, panthenol, or a combination thereof.

BRIEF DESCRIPTION OF THE DRAWINGS

Implementation of the present technology will now be described, by way of example only, with reference to the attached figures, wherein: FIGS. 1 and 2 are a bar graph showing the amount of retinol recovered during in vivo testing of the cosmetic composition in accordance with aspects of the disclosure.

It should be understood that the various aspects are not limited to the results, arrangements, and/or instrumentality shown in the drawings.

DETAILED DESCRIPTION OF THE DISCLOSURE

The cosmetic composition typically includes:

(a) about 0.01 to about 3 wt.% of retinol;

(b) about 0.1 to about 14 wt.% of sodium polyacrylate;

(c) about 0.2 to about 10 wt.% of one or more nonionic emulsifier; and

In some cases, the cosmetic composition achieves the improved penetration of retinol 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, include sulphoxides (such as dimethylsulphoxide, DMSO), azones (e.g., laurocapram), pyrrolidones, (for example 2-pyrrolidone, 2P), certain 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 provide improved penetration of retinol into adult human skin without using certain penetration enhancers.

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 combination of penetration enhancers or of a total amount of all penetration enhancers. For instance, the cosmetic composition is free of or essentially free of a combination of penetration enhancers or of a total amount of all penetration enhancers.

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 (e.g., retinol) 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 (e.g., retinol) 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.

The cosmetic composition may be formulated to be lotions, serums, creams, sprays or any other suitable form of product. 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. 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.).

In some instances, the amount of nonionic emulsifier in the cosmetic composition is about 0.2 to about 10 wt.%, about 0.2 to about 8 wt.%, about 0.2 to about 6 wt.%, about 0.2 to about 5 wt.%, about 0.2 to about 4 wt.%, about 0.2 to about 3 wt.%, about 0.2 to about 2 wt.%, about 0.2 to about 1 wt.%; about 0.5 to about 10 wt.%, about 0.5 to about 8 wt.%, about 0.5 to about 6 wt.%, about 0.5 to about 5 wt.%, about 0.5 to about 4 wt.%, about 0.5 to about 3 wt.%, about 0.5 to about 2 wt.%, about 0.5 to about 1 wt.%; about 0.75 to about 10 wt.%, about 0.75 to about 8 wt.%, about 0.75 to about 6 wt.%, about 0.75 to about 5 wt.%, about 0.75 to about 4 wt.%, about 0.75 to about 3 wt.%, about 0.75 to about 2 wt.%; about 1 to about 10 wt.%, about 1 to about 8 wt.%, about 1 to about 6 wt.%, about 1 to about 5 wt.%, about 1 to about 4 wt.%, about 1 to about 3 wt.%, or about 1 to about 2 wt.%, including ranges and subranges 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, it is preferable that 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.

Preferably, the cosmetic composition includes a nonionic emulsifier chosen from 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, and mixtures thereof.

The cosmetic compositions include a fatty phase comprising one or more fatty compounds. The amount of fatty phase (e.g., the total amount of fatty compounds) is typically in the range of about 0.5 to about 20 wt.%, based on the total weight of the cosmetic compositions. In some instances, the amount of fatty phase or total amount of fatty compounds is about 0.5 to 20 wt.%, about 0.5 to about 18 wt.%, about 0.5 to about 16 wt.%, about 0.5 to about 14 wt.%, about 0.5 to about 12 wt.%, about 0.5 to about 10 wt.%, about 0.5 to about 8 wt.%, about 0.5 to about 7 wt.%, about 0.5 to about 6 wt.%, about 0.5 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

2 to about 7 wt.%, about 2 to about 6 wt.%, about 2 to about 5 wt.%; about 3 to about 20 wt.%, about 3 to about 18 wt.%, about 3 to about 16 wt.%, about 3 to about 14 wt.%, about 3 to about 12 wt.%, about 3 to about 10 wt.%, about 3 to about 8 wt.%, about 3 to about 7 wt.%, about 3 to about 6 wt.%, about 3 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.% about 4 to about 7 wt.%, about 4 to about 6 wt.%, about 4 to about 5 wt.%; about 5 to about 20 wt.%, about 5 to about 18 wt.%, about 5 to about 16 wt.%, about 5 to about 14 wt.%, about 5 to about 12 wt.%, about 5 to about 10 wt.%, or about 5 to about 8 wt.%, about 5 to about 7 wt.%, or about 5 to about 6 wt.%, including all ranges and sub-ranges therebetween, based on the total weight of the cosmetic composition.

In some instance, the cosmetic compositions may include about 12 wt.% or less of a fatty phase (e.g., the total amount of fatty compounds). For example, the cosmetic composition may include about 12 wt.% or less, about 10 wt.% or less, about 9 wt.% or less, about 8 wt.% or less, about 7 wt.% or less, about 6 wt.% or less, or about 5 wt.% or less of a fatty phase, based on the total weight of the cosmetic composition.

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.

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.

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.
