Description

PCT/U82012/025910 COMPOSITION COMPRISING BANYAN TREE, LOTUS, AND CLOVER SERUM FRACTIONS (AGING) FIELD OF THE INVENTION The t ion relates to compositions comprising banyan tree, lotus, and clover serum fractions. The present invention also relates to methods for ing the appearance of aging mammalian skin using a composition comprising banyan tree, lotus, and clover serum fractions.
BACKGROUND OF THE INVENTION The epidermis, the outermost layer of the skin, comprises a ar continuum of four layers: the stratum corneum, the granular layer, the s layer, and the basal layer. Each cellular layer in the epidermis represents various stages along a process in which basal epidermal keratinocytes undergo a continuous cycle of proliferation, differentiation, and apoptosis, moving upward from the basal layer to finally yield corneocytes. These corneocytes form the cornified layer known as the stratum comeum.
Basal keratinocytes reside at the lower portion of the epidermis. These mitotically active cells undergo a proliferative cycle to generate er cells that are physically dislocated upward into the spinous and granular layers and undergo the process of differentiation into corneocytes. On passing through the spinous and granular layers, the cells undergo morphological changes that render them flatter in structure as they lose their cellular viability, undergo alternate keratin expression profiles, and transform into cellular ts. On average, a younger-aged epidermis turns over in about one month, shedding the older cells and ing them with newer ones, but this process can increase to over forty days in older skin.
The stratum corneum’s comeocytes remain connected to one other via proteins and lipids, creating a protective barrier between the organism and its outside environment. This y ted epidermal permeability barrier ons as a physical and selective barrier against chemical and biological insults. Important ons of this barrier include attenuation of the penetration of free radicals and prevention of penetration of harmful radiation, including UV ion, into deeper layers. The stratum corneum also acts as a permeability barrier and functions to prevent loss of body moisture to the outside environment. Dysfunction of this r can lead to chronic skin conditions, es, and in extreme cases can even en the viability of the organism.
Skin aging is a multifactorial process driven by both intrinsic (chronological aging) and extrinsic (environmental) factors, ing ultraviolet (UV) exposure, environmental toxins, pollutants, and smoking. It is well known in the art that the ability of the stratum corneum to cyclically generate new layers of skin diminishes with age so that the m corneum turnover rate is substantially reduced in aged skin, with the cornified layer ng lly thinner. This results in a reduction in the functioning capacity of the barrier so that harmful stimuli penetrate the stratum corneum more easily, leading to UV-damage, for example, of the underlying dermal layers, degradation of collagen and elastin, and eventually manifests in appearance as wrinkling and skin atrophy. ng of the stratum corneum by the sum of intrinsic and extrinsic aging factors increases the e appearance of fine lines and wrinkles. Further, the barrier suffers from an age-related increase in permeability to free radicals and a reduction in the amount of lipid in the intercellular matrix, decreasing barrier capacity to diffiise toxins from deeper layers. Recovery capacity of the barrier to environmental insult is also substantially d with age.
Thus, the skin’s barrier function is key to the skin’s ability to regenerate and protect itself from the appearance of aging skin. Accordingly, it would be desirable to provide compositions and methods of treatment that can improve the skin’s barrier function and also improve the appearance of aging skin.
SUMMARY OF THE INVENTION The present invention relates to compositions comprising banyan tree, lotus, and clover serum fractions and mixtures and/or combinations thereof. In one ment, the t invention provides use of a serum fraction blend in formulating topically applied skin compositions, said blend comprising banyan tree serum fraction, lotus serum fraction and clover serum fraction to increase the moisture and barrier function of human epidermis, as evidenced by the statistically significant up— regulation of claudin-l and aquaporin-3 in said human epidermis.
Also provided in another aspect is a process to increase the moisture and barrier on of human epidermis, as evidenced by the statistically significant up-regulation of claudin-l and aquaporin-3 in said human epidermis, by topically applying a skin care composition comprising a blend of banyan tree serum fraction, lotus serum fraction and clover serum fraction.
A method of improving the appearance of aging skin comprising the step of applying a first composition comprising an effective amount of banyan tree serum fraction, lotus serum fraction, and clover serum fraction blend to an area of aging skin, wherein the ition is applied for a period of time ent to improve the ance of the aging skin. In certain embodiments the composition also comprises a dermatologically acceptable carrier.
PCT/U82012/025910 In some embodiments the area of aging skin is aging facial skin. In particular embodiments, ing the appearance of aging skin comprises improving the appearance of wrinkles, fine lines, coarse deep lines, crevices, bumps, large pores; thickening of keratinous tissue (e.g., building the mis and/or dermis and/or sub-dermal layers of the skin); increasing the convolution of the dermal-epidermal border (also known as the rete ridges); skin ning; preventing loss of skin elasticity, for example, due to loss, damage and/or inactivation of functional skin elastin, resulting in such conditions as elastosis, sagging, loss of skin recoil from deformation; change in coloration to the skin, for example, under-eye circles, blotchiness (e.g., uneven red coloration due to, for example, rosacea), sallowness, discoloration caused by hyperpigmentation, etc.; and combinations thereof.
In response to the problems identified in the background, the present invention may take other forms. Further forms of the t invention will be appreciated in the detailed description that follows.
BRIEF DESCRIPTION OF THE DRAWINGS It is believed that the present invention will be better understood from the following description taken in conjunction with the accompanying gs. The nced drawings are not to be construed as limiting the scope of the present invention.

Skin tone is typically characterized over a larger area of the skin. The area ideally may be than 100 m2, but larger areas are envisioned such as the entirety of the facial skin or any of the facial skin surfaces.
Skin tone can be measured by image analysis. For example, overall lightness can be measured by L"< coordinate in L*a*b* color space (International Commission on Illumination). Chromophore mapping such as melanin mapping and melanin concentration may be used as an indicator of overall skin tone. Mean melanin may be calculated from the phore map data. Additionally, skin tone evenness can be determined by n evenness which also may be calculated from the Chromophore map data. Suitable Chromophore mapping techniques are discussed in the example below.
The term “facial skin surface” as used herein refers to one or more of ad, periorbital, cheek, perioral, chin, and nose skin surfaces.

PCT/U82012/025910 A. Serum Fractions Compositions of the present invention comprise effective amounts of banyan tree serum fraction, lotus serum fraction, and clover serum fraction.
Banyan tree, lotus, and clover serum fractions consist essentially of the flower, leaf, and stem serum ons obtained from Ficus Benghalensis, Nelumbo Nucz’fera, and Trz'folz'um Pratense, respectively. Preferred serum fractions herein are produced by Akzo Nobel Surface Chemistry LLC of Ossining, New York, USA, under the trade names Ficus Bengalensis Enriched Serum FractionTM (TNCI Name: Ficus Indica Flower/Leaf/Stem Juice), Lotus Enriched Serum FractionTM (INCI Name: Nelumbo Nucz’fem /Leaf/Stem Juice), and Red Clover Enriched Serum FractionTM (INCI Name: Trz'folz'um Pratense (Clover) Flower/Leaf/Stem Juice).
In some embodiments, the ition may comprise banyan tree serum fraction in an amount of from 0.001% to 15%, alternatively from 0.002% to 10%, alternately from 0.025% to 10%, in other embodiments from 0.05% to 10%, in others from 0.05% to 5%, and in others from 0.1% to 5%, by weight of the total ition. The composition may comprise lotus serum on in an amount of from 0.001% to 15%, alternatively from 0.002% to 10%, alternatively from 0.01% to 15%, alternately from 0.025% to 10%, in other embodiments from 0.05% to 10%, in others from 0.05% to 5%, and in others from 0.1% to %, by weight of the total composition. The ition may comprise clover serum fraction in an amount of from 0.001% to 15%, alternatively from 0.002% to 10%, alternatively from 0.01% to 15%, alternately from 0.025% to 10%, in other embodiments from 0.05% to 10%, in others from 0.05% to 5%, and in others from 0.1% to 5%, by weight of the total composition.
The method for making a serum fraction comprises the steps of: (a) separating cell juice from clean, fresh, un—wilted plant matter to obtain fresh cell juice, wherein no ous liquid is added prior or during said separating; (b) filtering said fresh cell juice to obtain fiber-free cell juice; and (c) fractionating said fiber-free cell juice to obtain the serum fraction for use herein. Suitable serum fraction preparation methods are set forth in US.
Patent No. 7,442,391, “Bioactive Botanical Cosmetic Compositions and Processes for their tion,” to Koganov, and in co-pending US. Provisional Application Serial No. 61/381,748, filed 10 September 2010 by Swanson et al., the disclosures of which are hereby incorporated by reference herein.
The resulting serum fractions have superior bioactivity versus traditionally prepared plant extracts. Unlike traditional extracts, the serum fraction is prepared from fresh plant cell juice that has been ically separated from the rest of the fresh plant material.
Importantly, no exogenous solvent (e.g., water, hexane, acetone, ethanol) is added during the juice separation process. The ing cell juice contains the full spectrum of compounds found in fresh plant , thus the resulting serum fractions contain a much broader range of active compounds than do traditional plant extracts, which contain only the narrow range of compounds that can be separated with a particular solvent.
Furthermore, using fresh plants maintains the integrity of the ive components inherently present in the fresh plant matter. Traditional plant ts are not prepared from fresh plant matter, but rather from dried plant material, which has undergone degradation due to dehydration. During dehydration, the cell walls are compromised, causing the ation of nds through mechanisms such as hydrolysis, oxidation, polymerization, Maillard reactions, and isomerization. When the dried leaves are extracted, the resulting extract thus contains these ation products that were not originally present in the fresh plant matter.
Accordingly, the composition of the resulting dry leaf extract greatly differs from that of fresh juice and the resulting serum on.
B. Skin Tone Agent In some embodiments, it may be desirable to include a skin tone agent in the composition. The skin tone agents can be included to further improve overall skin tone.
When present, the compositions of the present invention n up to about 50%, 40%, 30%, %, 10%, 5%, or 3%, by weight of the composition, of the skin tone agent. When present, the itions of the present invention contain at least about 0.001%, 0.01%, 0.1%, 0.2%, 0.5%, or 1%, by weight of the composition, of the skin tone agent. Suitable ranges include any combination of the lower and upper limits including suitable ranges from about 0.1% to about 50%; from about 0.2% to about 20%; or from about 1% to about 10%, by weight of the composition, of the skin tone agent. The amounts listed herein are only to be used as a guide, as the optimum amount of the skin tone agent will depend on the specific active selected since their potency does vary erably.
Suitable skin tone agents include, but are not limited to, sugar amines, vitamin B3 compounds, arbutin, rbutin, l,3-dihydroxy—4-alkylbenzene such as hexylresorcinol, sucrose dilaurante, bakuchoil (4-[(1E, SS)—3~ethenyl-3,7-dimethyl ~ 1,6 octadienyl] phenol or 2012/025910 monterpene phenol), pyrenoine (available from h , France), panicum miliaceum seed extract, arlatone dioic acid, cinnamic acid, ferulic acid, achromaxyl, methyl nicotinamide, oil soluble licorice extract, folic acid, undecylenic acid (i.e., undecenoic acid), zinc undecylenate, thiamine (Vitamin B1) and its hloride, tophan, helianthus annuus ower) and vitis Vinifera ) leaf extract, carnosine (i.e., dragosine), methyl gentisate, 1,2-hexandiol and l,2-0ctandiol (i.e., combination sold as Symdiol 68 by Symrise AG, Germany), inositol, decylenoylphenylalanine (e.g., sold under the tradename Sepiwhite by , France), kojic acid, hexamidine compounds, salicylic acid, and retinoids including retinol and retinyl propionate.
In certain ments, the additional skin tone agent is selected from vitamin B3 compounds, sugar amines, hexamidine compounds, salicylic acid, hydroxy—4~ alkylbenzene such as hexylresorcinol, and retinoids. As used herein, "vitamin B3 compound" means a compound having the formula: wherein R is - CONH2 (i.e., niacinamide), — COOH (i.e., nicotinic acid) or - CHzOH (i.e., nicotinyl alcohol); derivatives thereof; and salts of any of the foregoing.

II. Methods of Treatment Various methods of ent, application, regulation, or improvement may utilize the aforementioned compositions. Identification of a region of aging skin may occur on any skin surface of the body. Skin surfaces of the most concern tend to be those not typically covered by clothing such as facial skin surfaces, hand and arm skin surfaces, foot and leg skin surfaces, and neck and chest skin surfaces (e.g., décolletage). In particular, identification of the region of aging skin may be on a facial skin surface including the forehead, perioral, chin, periorbital, nose, and/or cheek skin surfaces.
The method may comprise the step of applying the ition to the usly fied area of aging skin, or an area where one seeks to prevent the appearance of aging skin. Many regimens exist for the application of the composition. The composition may be applied at least once a day, twice a day, or on a more nt daily basis, during a treatment period. When applied twice daily, the first and second applications are separated by at least 1 to about 12 hours. lly, the composition may be applied in the morning and/or in the evening before bed.
PCT/U82012/025910 The treatment period is ideally of sufficient time to provide an improvement in the appearance of aging skin. The treatment period may be at least about 1 week, and in some embodiments the treatment period may last about 4 weeks or about 8 weeks. In certain embodiments, the treatment period will extend over multiple months (i.e., 3-12 months) or multiple years. In one embodiment the composition is applied at least once a day during a treatment period of at least about 4 weeks or at least about 8 weeks. In one embodiment the composition is applied twice a day during a treatment period of at least about 4 weeks or 8 weeks.
The step of applying the composition may be accomplished by localized application.
In reference to ation of the ition, the terms ized”, “local”, or “locally” mean that the ition is delivered to the targeted area (such as age spots) while minimizing delivery to skin surface not requiring treatment. The composition may be applied and lightly massaged into area of aging skin. The form of the composition or the dermatologically acceptable carrier should be ed to facilitate localized application.
While certain ments of the present invention contemplate applying a composition locally to an area, it will be appreciated that compositions of the t invention can be applied more generally or broadly to one or more skin surfaces.
In some embodiments, the composition may be red by a variety of applicators appropriate for localized and general application. Such applicators can include droppers, applicator wands, cotton swabs, or any other suitable device. Other suitable applicators include SH-0127 pen applicator ble from Shya Hsin Plastic Works, Inc., Taiwan and either the Xpress Tip or liquid filled swab available from SwabPlus, Inc., China. The applicator may be configured to easily apply the composition to age spots having an approximate er between about 2 mm and about 10 mm and allowing for a dosed amount of the composition of between about 1 to about 50 uL/cm2 or between about I to about SuL/cmz. In another embodiment, the ition is applied to the one or more aging spots and more generally to one or more facial skin surfaces contemporaneously (z'.e., over a period of less than 30 s or, more typically, less than 5 minutes).
While some methods described herein contemplate applying the compositions of the t invention with an applicator, it will be appreciated that applicators are not required and the compositions of the present invention can also be applied directly by using one’s finger or in other conventional manners.
PCT/U82012/025910 In one embodiment, the method comprises the steps of applying a first composition comprising an effective amount of banyan tree serum fraction, lotus serum fraction, and clover serum fraction to a skin surface and of applying a second composition to the skin surface, before or after the first composition. The first and second compositions may be any compositions described ; however, the second composition may optionally se an effective amount of the serum ons present in the first ition. The second composition may comprise one or more tone agents, sunscreen actives, nflammatory agents, or optional components. The first composition may be generally or locally applied, While the second composition may be lly or locally applied to the skin surface ing the aging skin to which the first composition is applied. In certain embodiments, the skin surface is facial skin surface which include one or more of the forehead, perioral, chin, periorbital, nose, and cheek skin surfaces. In another embodiment, the first and second itions are applied contemporaneously to at least the cheek, forehead, and chin/perioral skin surfaces. For general application to a skin surface and, particularly a facial skin surface, the closed amount of the first or second composition may be between about 1 to about 50 uL/cm2 per application (i.e., per single application to the skin surfaces).
Suitable methods may comprise any one or more of the entioned steps. All of the aforementioned steps are applicable to application, treatment, regulation, and/or improvement of aging skin appearance. One suitable method of improving the appearance of aging skin includes the step of topically applying a composition comprising an effective amount of banyan tree serum fraction, lotus serum fraction, and clover serum fraction blend to the aging skin surface, wherein the composition is applied for a period of time sufficient for the serum fraction blend to improve the ance of the aging skin.
III. Mechanisms ofAction The stratum corneum is a tightly regulated epidermal permeability barrier and functions as a physical and selective barrier t chemical and biological s, as well as acts as a permeability barrier to prevent loss of body moisture to the outside environment.
The m corneum’s cells control these barriers by regulating the movement of water, ions, and proteins across them. Flow of ions and molecules between cells, often referred to as the paracellular permeability pathway, is regulated by tight junctions. (Koval, Michael.
Claudins — Key Pieces in the Tight Junction Puzzle. Cell ication and Adhesion. 13:127—138, 2006.) Tight ons are sites of cell-cell contact composed of a number of transmembrane and peripheral proteins, assembled into a complex tethered to the cytoskeleton. Of these transmembrane proteins, those identified as “Claudins” are the major determinant of cellular permeability. Claudins serve several roles in maintaining barrier on. Claudins are a major component of the strands that constitute the permeability barrier to limit diffusion of ns and other macromolecules between cells, and they also form specific paracellular channels that regulate ion diffusion between cells. n-l mutations have been associated with several types of ichthyosis (a family of skin disorders causing dry, ned, scaly, or flaky skin), and a study has shown that the epidermal barrier function of claudin-l deficient mice is so compromised that their cells are unable to hold water, causing the skin to dry up and leading to death within a day. (M. Furuse, et al. The Journal of Cell Biology, 156 (No. 6): 1099-1111, 2002) Aquaporin-3 (AQP3) is a membrane transporter of water and glycerol expressed in the basal layer of epidermal keratinocytes. Aged human skin has been shown to experience decreased AQP3 expression, which also correlates to a reduced stratum corneum water content and elasticity compared with young, undamaged skin. In studies involving AQP3- knockout mice, reduced AQP3-dependent glycerol transport in AQP3-deficiient epidermis has been show to be sible for dehydrated, inelastic skin. (“Aquaporin—3 functions as a glycerol transporter in mammalian skin,” hikuma M, Biol Cell. 2005 Jul;97(7):479- 86.); (”Roles of Aquaporin-3 in the mis”, Hara—Chikuma, M., J Invest Dermatol. 2008 Sep;128(9):2145-51. Epub 2008 Jun 12); (“Glycerol replacement corrects ive skin hydration, elasticity, and barrier function in aqaporin-3—deficient mice,” Hara M., Proc Natl Acad Sci U S A. 2003 Jun (12):7360-5. Epub 2003 May 27).
The blend of banyan tree, clover, and lotus serum fractions resulted in positive increases in moisture and barrier function, as evidenced by the statistically significant up- regulation of claudin—l and rin-3 (“AQP3”) in Example 3 below.
In Example 2, the blend’s effect on nine different genes associated with aging skin was ted. These nine genes, and their associated functions, are described in Table l of Example 2. The fold-increase / decrease in expression, versus control, was determined for the aging-related genes at two ent concentration levels. In both cases, as shown in Tables 2a and 2b, the blend effected a positive fold increase in all nine genes, indicating the desirable up—regulation of that gene, and thus a positive anti—aging benefit.

The compositions of the present invention are generally prepared by conventional methods such as are known in the art of making topical itions. Such methods typically involve mixing of the ingredients in one or more steps to a relatively uniform state, with or without heating, cooling, ation of vacuum, and the like. Typically, emulsions are prepared by first mixing the aqueous phase materials separately from the fatty phase materials and then combining the two phases as appropriate to yield the desired continuous phase. The compositions are preferably prepared such as to optimize stability (physical stability, chemical stability, tability) and/or delivery of the active als. This optimization may include appropriate pH (e.g., less than 7), exclusion of materials that can complex with the active agent and thus negatively impact stability or delivery (e.g., exclusion of contaminating iron), use of approaches to prevent complex formation (e.g., appropriate dispersing agents or dual tment ing), use of appropriate photostability approaches (e.g., incorporation of sunscreen/sunblock, use of opaque packaging), etc.
Example 2 — Ex Vivo Tissue Analysis Individual banyan tree, lotus, and clover serum fractions, as well as their blend, were evaluated at two different concentrations according to the method described herein. The fold- increase / decrease in expression, versus control, was determined for the aging-related genes set forth in Table 2, below. A positive fold se tes the desirable up-regulation of that gene, and thus a positive anti-aging benefit.
