TITLE

COSMETIC COMPOSITIONS AND METHODS FOR PROVIDING BROAD AND FULL SPECTRUM PHOTO PROTECTION FIELD OF THE DISCLOSURE

The instant disclosure relates to compositions and methods for providing broad and full spectrum photo protection to skin. The methods typically entail applying to skin a unique cosmetic composition comprising one or more antioxidants. The compositions may also optionally include UV filters to provide additional protection from UV light.

BACKGROUND

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, micro-organisms, and ultraviolet damage. The health and appearance of skin, however, can deteriorate due to environmental factors, genetic makeup, nutrition, and sun exposure.

The negative effects of exposure to ultraviolet ("UV") light are well-known. Prolonged exposure to sunlight causes damage such as sunburn to the skin and dries out hair making it brittle. When skin is exposed to UV light having a

wavelength of from about 290 nm to about 400 nm, long term damage can lead to serious conditions such as skin cancer.

UV light also contributes to aging by causing free radicals to form in the skin. Free radicals include, for example, singlet oxygen, hydroxyl radicals, the superoxide anion, nitric oxide and hydrogen radicals. Free radicals attack DNA, membrane lipids and proteins, generating carbon radicals. These in turn react with oxygen to produce a peroxyl radical that can attack adjacent fatty acids to generate new carbon radicals. This cascade leads to a chain reaction producing lipid peroxidation products. Damage to cell membranes results in loss of cell permeability, increased intercellular ionic concentration, and decreased ability to excrete or detoxify waste products. The end result is a loss of skin elasticity and the appearance of wrinkles. This process is commonly referred to as photo-aging. Although UV radiation can be problematic, over 90% of solar energy is from visible light and infrared (IR) radiation. Visible light and IR radiation, especially IRA (770-1400 nm), penetrates deep into human skin than UV radiation, and can easily reach the dermis. Visible light, especially high energy visible light, can induce pigmentation in a similar manner as UVA, and IR radiation can impair proper functioning of mitochondria. Visible light and IR radiation both contribute to photoaging by degrading collagen through induction of MMP1 enzyme (without induction of the natural endogenous protection MMP1 inhibitor), generating free radicals and decreasing antioxidant content in human skin. With aging, the outer skin layer (epidermis) thins, even though the number of cell layers remains unchanged. The number of pigment-containing cells

(melanocytes), however, decreases. Therefore, the skin appears pale and translucent. Large pigmented spots (age spots, liver spots, or lentigos) may appear in sun-exposed areas. Changes in the connective tissue reduce the skin's strength and elasticity. It is more noticeable in sun-exposed areas (solar elastosis). Elastosis produces the leathery, weather-beaten appearance common to farmers, sailors, and others who spend a large amount of time outdoors. Dehydration increases the risk of skin injury. Poor nutrition can also negatively impact the skin, causing dryness, rash, and puffiness. SUMMARY OF THE DISCLOSURE

The instant disclosure relates to compositions and methods for providing full and broad spectrum photo protection to skin. The compositions and methods use one or more antioxidants; optionally, one or more solubilizers; and a cosmetically acceptable carrier. UV filters may also be included to provide additional protection from UV light. Additional components, such as, additional active ingredients, emulsifiers, and silicone oils may also be used.

In one aspect, the instant disclosure relates to methods and compositions for providing at least broad spectrum photo protection to skin, which includes protection from infrared (IR) radiation and/or visible light. The methods typically entail applying to skin a unique cosmetic composition comprising one or more antioxidants. The inventors discovered that certain antioxidants and combinations of antioxidants provide unexpected protection from both infrared radiation and visible light and are therefore useful in cosmetic compositions for protecting skin against IR radiation and visible light, in addition to imparting other benefits to the skin, such as improving the health and appearance of skin.

These methods entail topically applying to the skin of a subject a cosmetic composition comprising: (a) one or more antioxidants selected from the group consisting of baicalin, polydatin, venuceane™, ferulic acid, silymarin, punica granatum extract, mango leaf extract, hesperetin, soliprin™, catechin, astilbin, and Dihydroxymethoxy dihydrochalcone (DHC V); (b) optionally, one or more solubilizers; and (c) a cosmetically acceptable carrier; wherein the combination of (a), optional (b), and (c) alone, provide at least broad spectrum protection from both infrared (IR) radiation and/or visible light. In some cases, the one or more antioxidants of (a) includes at least baicalin.

Also, although not required, in many instances, one or more solubilizers of (b) are included in the cosmetic composition. The solubilizers may be, for example, hydrotropes. A non-limiting list of possible hydrotropes includes nicotinamide, caffeine, sodium PCA, sodium salicylate, urea, and hydroxyethyl urea. Further, the compositions of the instant disclosure, in some cases, include (d) one or more emulsifiers, which may be amphoteric, anionic, cationic, nonionic, or a mixture thereof. Moreover, the compositions may be in the form of an emulsion. Other non-limiting components that can optionally be included in the

compositions of the instant disclosure include, for example: (e) one or more UV filters; (f) one or more skin active ingredients; and (g) one or more silicon oils. The one or more UV filters of (e) may be included to provide additional protection from UV light, thereby resulting in a cosmetic compositions providing full spectrum photo protection (protection from IR radiation, visible light, and UV radiation).

These cosmetic compositions for providing at least broad spectrum photo protection to skin are also useful in other methods, such as methods for: providing anti-aging benefits to the skin; whitening or preventing darkening of skin; improving the appearance of skin; strengthening skin's natural antioxidant defenses;

diminishing the visible signs of skin aging; and improving skin's radiance and firmness. In another aspect, the instant disclosure relates to compositions and methods for providing full spectrum photo protection to skin, which includes protection from infrared (IR) radiation and/or visible light in addition to protection from UV radiation. The inventors discovered that certain antioxidants such as baicalin and combinations of other antioxidants with baicalin provide unexpected protection from infrared radiation, visible light, and UV radiation. Thus, the compositions are particularly useful for protecting skin from the harmful effects of these types of exposure. The compositions and methods are also useful for imparting other benefits to the skin, such as improving the health and appearance of skin. The compositions typically include: (a) baicalin; (b) one or more antioxidants selected from the group consisting of venuceane™, polydatin, hesperetin, mango leaf extract, vitamin C; (c) optionally, one or more solubilizers; and (d) a cosmetically acceptable carrier.

Also, although not required, in many instances, one or more solubilizers of (c) are included in the cosmetic compositions. The solubilizers may be, for example, hydrotropes. A non-limiting list of possible hydrotropes include nicotinamide, caffeine, sodium PCA, sodium salicylate, urea, and hydroxyethyl urea. Further, the compositions of the instant disclosure, in some cases, include (e) one or more emulsifiers, which may be amphoteric, anionic, cationic, nonionic, or a mixture thereof. Moreover, the compositions may be in the form of an emulsion. Other non-limiting components that can optionally be included in the

compositions of the instant disclosure include, for example: (f) one or more UV filters; (g) one or more skin active ingredients; and (h) one or more silicon oils. The one or more UV filters of (f) may be included to provide additional protection from UV light.

These cosmetic compositions are useful in methods for providing full spectrum photo protection to the skin. Nonetheless, the compositions are

additionally useful in methods for: providing anti-aging benefits to the skin; whitening or preventing darkening of skin; improving the appearance of skin; strengthening skin's natural antioxidant defenses; diminishing the visible signs of skin aging; and improving skin's radiance and firmness. In another aspect, the instant disclosure relates to compositions and methods for providing full spectrum photo protection to skin, which includes protection from infrared (IR) radiation and/or visible light in addition to protection from UV radiation. The inventors discovered that certain antioxidants such as silymarin and combinations of other antioxidants with silymarin provide unexpected protection from infrared radiation, visible light, and UV radiation. Thus, the compositions are particularly useful for protecting skin from the harmful effects of these types of exposure. The compositions and methods are also useful for imparting other benefits to the skin, such as improving the health and appearance of skin. The compositions typically include: (a) silymarin; (b) one or more antioxidants selected from the group consisting of ferulic acid, Vitamin C, polydatin, and hespertin C; (c) optionally, one or more solubilizers; and (d) a cosmetically acceptable carrier. Also, although not required, in many instances, one or more solubilizers of (c) are included in the cosmetic compositions. The solubilizers may be, for example, hydrotropes. A non-limiting list of possible hydrotropes include nicotinamide, caffeine, sodium PCA, sodium salicylate, urea, and hydroxyethyl urea. Further, the compositions of the instant disclosure, in some cases, include (e) one or more emulsifiers, which may be amphoteric, anionic, cationic, nonionic, or a mixture thereof. Moreover, the compositions may be in the form of an emulsion.

Other non-limiting components that can optionally be included in the

additionally useful in methods for: providing anti-aging benefits to the skin; whitening or preventing darkening of skin; improving the appearance of skin; strengthening skin's natural antioxidant defenses; diminishing the visible signs of skin aging; and improving skin's radiance and firmness.

More exhaustive but non-limiting lists of components useful in the instant compositions disclosed herein are presented below. Solubilizers

The solubilizers are typically compounds or groups of compounds that help solubilize the resveratrol, the polydatin, and/or the baicalin in the compositions of the instant disclosure. One or more solubilizers may be a hydrotrope, but the

solubilizers are not required to be hydrotropes. Hydrotropes (or hydrotropic agents) are a diverse class of water-soluble compounds that are characterized by an amphiphilic molecular structure and an ability to dramatically increase the solubility of poorly soluble organic molecules in water.

Many hydrotropes have an aromatic structure with an ionic moiety, while some of them are linear alkyl chains. Although hydrotropes noticeably resemble surfactants and have the ability to reduce surface tension, their small hydrophobic units and relatively shorter alkyl chain distinguish them as a separate class of amphiphiles. Consequently their hydrophobicity is not sufficient enough to create well organized self-associated structures, such as micelles, even with a high concentration.

Common hydrotropic molecules include: sodium 1 ,3-benzenedisulfonate, sodium benzoate, sodium 4-pyridinecarboxylate, sodium salicylate, sodium benzene sulfonate, caffeine, sodium p-toluene sulfonate, sodium butyl monoglycolsulfate, 4- aminobenzoic acid HCI, sodium cumene sulfonate, Ν,Ν-diethylnicotinamide, N- picolylnicotinamide, N-allylnicotinamide, 2-methacryloyloxyethyl phosphorylcholine, resorcinol, butylurea, pyrogallol, N-picolylacetamide 3.5, procaine HCI, proline HCI, nicotinamide, pyridine, 3-picolylamine, sodium ibuprofen, sodium xylenesulfonate, ethyl carbamate, pyridoxal hydrochloride, sodium benzoate, 2-pyrrolidone, ethylurea, Ν,Ν-dimethylacetamide, N-methylacetamide, and isoniazid. Hydrotropes can be found in Lee J. et al., "Hydrotropic Solubilization of Paclitaxel: Analysis of Chemical Structures for Hydrotropic Property", Pharmaceutical Research, Vol. 20, No. 7, 2003; and Lee S. et al., "Hydrotropic Polymers: Synthesis and Characterization of

Polymers Containing Picolylnicotinamide Moieties", Macromolecules, 36, 2248-2255, 2003. Additional hydrotropes include nicotinamide (Vit B3), caffeine, sodium PCA, sodium salicylate, urea, an dhydroxyethyl urea.

Implementation of the present disclosure is provided by way of the following examples. The examples serve to illustrate the technology without being limiting in nature.

Examples Example 1

A sensitive in vitro ROS (Reactive Oxygen Species) probe was used to evaluate the protective effects of antioxidants on live skin cells against visible light and infrared radiation (IR). Based on a blind screening of 26 compounds, 12 compounds were discovered that efficiently (>40%) decrease the ROS induced by visible light and/or IR radiation on human skin keratinocytes and/or fibroblasts.

These compounds (or mixtures of these compounds) provide biological protection for skin cells against visible light and infrared radiation. Human cells were pre-treated with and without antioxidants for 24 hours at a very low concentration (10 pg/ml (0.001 %)). After incubation for 24 hours, the cells were rinsed and the medium changed in order to remove all the antioxidants before light exposure. The cells were exposed to visible light (100 J/cm²) and infrared radiation (200 J/cm²) using Xenon Light Source 300W Monochromatic Light with Filters Max-303 (Asashi Spectra company). After exposure to the visible light and the IR radiation, a new ROS probe was incubated with the cells for one hour to track the in vitro ROS produced. A comfocal microscope and associated software was used to image the fluorescent signals from individual cells and quantify the

fluorescence intensity. By comparing with control samples without a pretreatment of antioxidants, it was possible to quantify the protection effect. A summary of the results is provided in the table below and the results are graphically presented in Figure 1 and Figure 2.

Astilbin Medium Medium

DHC V Medium Medium

In the table above, "strong" refers to a percent protection greater than 70%, "Medium" refers to a percent protection less than or equal to 70% but greater than equal to 40%. "Low" refers to a percent protection less than 40%. The term "negative" is used when there is no protection. The results presented in the table above are also graphically shown in Figure 1 and Figure 2. The protection percentage was defined according to the equation below (wherein the term "AOX" refers to "antioxidant"). ROS light exposure - ROS AOX + light expsore

Protection % = X 100%

ROS light exposure - ROS no light expsore

Since the in vitro tests were done on live human skin cells, kerotinocytes and fibroblasts, and the antioxidants in the cell culture media were removed before light exposure, the results directly predict the biological protection effects of the antioxidants on skin against visible light and infrared radiation. This was further confirmed by the absorption spectrum of these antioxidants, which showed no absorption in the visible light and infrared radiation area.

A sensitive in vitro ROS (Reactive Oxygen Species) probe was used to evaluate the protective effects of antioxidants on live skin cells (kerotinocytes and fibroblasts) against visible light and infrared radiation (IR). Human skin cells were pre-treated with and without antioxidants for 24 hours at a very low concentration (10 pg/ml (0.001 %)) (antioxidant ratio 1 : 1 ). After incubation for 24 hours, the cells were rinsed and the medium changed in order to remove all the antioxidants before light exposure. The cells were exposed to a full spectrum generated by Oriel® Sol3A® Class AAA Solar (1000W). After exposure to ~4 suns for 250 seconds, the ROS probe was incubated with the cells and used to track the in vitro ROS produced. Control samples without light exposure or antioxidant treatment were always tested to evaluate the normal ROS level in healthy skin cells, which later was used to normalize other experimental ROS levels in each experiment.

A comfocal microscope and associated software was used to image the fluorescent signals from individual cells and quantify the fluorescence intensity. Because the in vitro tests were done on live human skin cells, kerotinocytes and fibroblasts, and the antioxidants in the cell culture media were removed before light exposure, the results directly predict the biological protection effects of the antioxidants on skin cells against visible light and infrared radiation. This was further confirmed by the absorption spectrum of these antioxidants, which showed no absorption in the visible light and infrared radiation area.

In the context of the instant disclosure, the phrase "broad spectrum photo protection" refers to protection against at least visible light and/or IR radiation. In the context of the instant disclosure, the term "full spectrum photo protection" refers to protection against at least UV radiation and to protection against visible light and/or IR ration.

The difference between "broad spectrum photo protection" and "full spectrum photo protection" is that "full spectrum photo protection" necessarily includes protection against UV radiation in addition to protection against visible light and/or IR radiation. "Broad spectrum photo protection," however, includes protection of visible light and/or IR radiation but not necessarily protection against UV radiation. The addition of UV filters to a composition providing "broad spectrum photo protection" would transform the composition into one that provides "full spectrum photo protection" (because the addition of the UV filters allows the composition to provide protection against UV radiation and visible light and/or IR radiation.

The terms "a," "an," and "the" are understood to encompass the plural as well as the singular. The expression "at least one" means "one or more" and vice versa, and thus includes individual components as well as mixtures/combinations.

The term "about" when referring to a value, is meant specifically that a measurement can be rounded to the value using a standard convention for rounding numbers. For example, "about 1 .5" is 1 .45 to 1 .54. All values set forth herein can be modified with the term "about," if desired to impart the meaning above, or recited without the term, regardless of whether the term "about" is specifically set forth (or is absent) in conjunction with any particular value in the specification.

All ranges and values disclosed herein are inclusive and combinable. For examples, any value or point described herein that falls within a range described herein can serve as a minimum or maximum value to derive a sub-range, etc.

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.
