Description:
Multi-Functional, Structured, Glycidic / Non-Glycidic Matrices Field of Invention

The invention in certain embodiments is directed to topical and hair care products - including, stable, multi-functional dermatocosmetic and conditioning ingredients and externally applied products (i.e., finished formulations) that provide skin and hair health benefits including improved protection of the skin and hair from environmental stress, increased moisture retention, improved skin barrier function and/or hair conditioning.

Background of the Invention

Constantly barraged by environmental stressors - heat, cold, atmospheric and airborne pollutants, and ultraviolet radiation, among others - human skin protects the body by repairing damage and restoring and maintaining homeostasis. It does so through a series of inflammatory responses that can also have adverse skin health effects. By breaking down the skin's extracellular matrix proteins (collagen and elastin), inflammation can result in thinner, less elastic and wrinkled skin. To counter environmental stress, formulators of personal care and dermatologic products have relied on safe, effective, proven emollients and barrier-protecting ingredients - petrolatum and triglyceride butters, notably shea butter.

Use of petrolatum as an emollient for relieving dry skin conditions, including flaking skin, chapping, windburn and sunburn has long history of use in the personal care and medical arts. See, e.g., 43 Fed. Reg. 34628, 34639.

Where petrolatum is the sole moisturizing ingredient, moisturization benefits typically require that petrolatum be included in a finished formulation at a concentration of at least about 3% by weight of the formulation (3%+ petrolatum).

At certain use levels (30 percent or higher) petrolatum is approved by the US Food and Drug Administration in a monograph as an over-the-counter (OTC) skin protectant agent, useful for providing temporary protection of minor cuts, scrapes, and burns as well as drying effects of wind and cold weather. Additionally, when used at OTC concentrations, petrolatum can temporarily protect and help relieve chapped or cracked skin and lips.

A variety of grades (i.e., types) of petrolatum suitable for use in topical formulations are commercially available, including from Sonneborn LLC (Parsippany, NJ). In cosmetic applications, petrolatum can be found at any usage level up to 100% in skin care, body care and hair care for moisturization, TEWL function, emolliency, and texture effects. Petrolatum is an effective, economical, versatile, safe, and inert emollient used widely in mass market products, and has limited application for active skin care claims within the anti-aging or natural/plant based market. At high use levels required for monographed skin protectant claims (30%), petrolatum has a low sensory appeal.

Vegetal-derived "butters" are triglyceride-based emollients used in topical products and have a melting point of typically in the range of from 20 to 40.5°C. Butters are generally described in terms of the fatty acid composition of the constituent triglycerides. Longer fatty acid chain lengths increase melting points; higher degrees of unsaturation translate to lower melting points.

Vegetal Butters have long been recognized and used for emolliency and moisturization in cosmetic and personal care applications. However, use levels of vegetal butters in emulsions and anhydrous systems can often be limited by their complex mix of various fatty acids and inherent polymorphic crystallization behavior. At higher concentrations (at least 2%), inclusion of a vegetal butter that has been minimally refined, bleached and deodorized (i.e., an "RBD" butter) in a finished formulation can result in grainy emulsion structures or greyish formations - so-called "bloom". Additionally, when RBD vegetal butters are used in a finished product at a concentration that provides meaningful functionality, which concentration is at least 2%, the product can, over time, exhibit changes in one or more of viscosity, color and/or gloss. In many instances, emulsion products containing high levels of RBD vegetal butter(s), greater than 2%, are observed to separate.

A mixture of petrolatum and an RBD vegetal-derived butter is likewise subject to formulation limitations, including instability and undesirable sensory properties. Prior to the present invention, suitable petrolatum-based topical products could not be formulated with more than about two percent RBD vegetal butter; at concentrations in excess of 2% wt/wt RBD shea butter in a formulation containing 3%+ petrolatum, grains are perceptible - both on visual inspection and by touch. Moreover, adding more than 2% wt/wt RBD vegetal butter to a 3%+ petrolatum formulation is known to result in gloss and/or discoloration.

Shea butter, like petrolatum, provides emolliency and moisturization and has been used in a wide range of personal care applications. See, e.g., J. Alander "Shea butter with improved moisturisation properties" Personal Care (September 2009).

The unsaponifiable content of shea butter - as much as 7% to 10% - has been shown in both in vitro and ex vivo skin models to possess anti-inflammatory, collagen- protecting/stimulating, and fibroblast-proliferating properties. Idem; see also, A-C Anderson, "Protection against stress by natural triterpene esters" Personal Care (June 2011). Triterpene esters constitute 2% to 5% of RBD shea butter. In order for triterpene esters in shea butter to have a clinically meaningful effect in a 3%+ petrolatum formulation - such as protecting against stress-related breakdown of skin extracellular matrix proteins (collagen and elastin) by reducing expression of matrix metalloproteinases or inhibition of the release of pro-inflammatory mediators like PGE2, TNF-a and IL-Ιβ - shea butter must be included at a concentration of at least about 2% - a level that commonly results in bloom, graininess, discoloration or other organoleptic deficiencies.

Interesterified, non-fractionated vegetal butters - especially shea butter - are known to be superior to their RBD counterparts in several respects. First, interesterification raises the melting point of the shea butter almost twenty degrees - from 33°C (for RBD) to 51°C (for interesterified, non-fractionated). Second, interesterified, non-fractionated shea butter crystallizes more rapidly (in less than 24 hours) than its RBD counterpart (which takes 5 to 7 days). Third, at higher temperatures, interesterified, non-fractionated shea butter retains more of its solid content than RBD shea butter.

International Patent Application Publication WO 2006/037341 discloses low- lauric, low-trans fat, cocoa butter substitutes useful for food and other

applications. The compositions in WO 2006/037341 are a specific type of inter- esterified and fractionated fat - with a low melting fat fraction that has a final melting point around and below body temperature, and a steep SFC-melting profile. (As used in the present application the term "body temperature" is to be understood as about 37°C.) Comparative Example 7 in WO 2006/037341 lists two lip balm formulations. The two formulations in Example 7 both contain 55% white petrolatum and are identical except with respect to triglyceride component. The first formulation in Example 7, "Test Composition," is made with 6% of a low melting inter-esterified and fractionated triglyceride as described immediately above. The second formulation, "Reference Composition" is made with 6% Illexao 30-61, a palm glyceride having a melting point of 34°C.

In marked contrast to the formulations in Example 7 of WO 2006/037341, compositions of certain embodiments of the present invention are created from an inter-esterified, non-frationated triglyceride component that has a final melting point above or significantly above body temperature (e.g., 51°C), as well as a very slow (i.e., flat) SFC-melting profile. By "significantly above body temperature" is meant a temperature at least 10%, at least 20%, or at least 25% above body temperature. The physical properties of a melting point above or significantly above body temperature and a very slow (i.e., flat) SFC-melting profile are central to achieving inventive properties of certain embodiments of the present invention - such as, achieving superior skin barrier protection and moisturization as measured by TEWL (i.e., by reducing trans-epidermal water loss), and/or durable protective coating on hair. The Illexao 30-61 palm triglyceride used in Example 7 of WO 2006/037341and the interesterified, non-fractionated, shea butter used in certain embodiments of the present invention differ in another functionally important respect to the inventive claims. Ilexao 30-61 contains less than about 1% unsaponifiables, and, consequently, a very low content of functional triterpene esters. The

interesterified, non-fractionated shea butter used in certain embodiments of the present invention has an unsaponifiable content of about 7% to about 10%. At this level of unsaponifiables, triterpene esters are present in amount to provide anti-inflammatory, collagen-protecting/stimulating, and fibroblast-proliferating and other skin health benefits. In combination, the above properties make the interesterified, non-fractionated shea butter that is a component of certain embodiments of the present invention more crystalline and thermally stable than its RBD counterpart. For example, if a finished formulation containing certain interesterified, non-fractionated shea butter of the present invention were to be exposed to an elevated temperature sufficient to melt its crystals (e.g., during storage), when the product was placed in cooler conditions that would allow the crystals to recrystallize, the crystals would do so achieve a stable form (transforming into β polymorphs) within 24 hours. In contrast, RBD shea butter crystals begin to melt not only at a lower temperature than interesterified, non-fractionated shea butter crystals but also more quickly. Moreover, when RBD shea butter crystals begin to recrystallize, a considerably longer period of time (5 to 7 days) is required to stabilize as β polymorphs.

In summary, there has been a long-existing and unmet commercial need within the Personal Care Industry for stable, cosmetically elegant (i.e., not unctuous), 3%+ petrolatum-based products that can incorporate triglyceride-based butters at functional threshold concentrations, e.g., of at least 2% wt/wt without reducing crystalline stability and reducing the functional TEWL performance of externally applied skin and hair treatment formulations. This need is demonstrably present for petrolatum-based products that contain 30% or more petrolatum (meeting OTC monograph requirements for "skin protectant"); evidenced by the commercial absence of OTC "skin protectant" compliant formulations (with 30% or more petrolatum) which also contain triglyceride-based vegetal-derived butters at functional threshold concentrations of at least 2%. The multifunctional structured, glycidic / non-glycidic matrices of certain embodiments of the present invention meet these needs by overcoming physical instability and eliminating the reduction of TEWL performance expected to be present in 3%+ petrolatum-based products that incorporate triglyceride-based vegetal-derived butters at functional threshold concentrations of at least 2%.

Definitions "Dermatocosmetic" means suitable for inclusion in a cosmetic, personal care or dermatologic product for topical application on mammalian skin (epidermis, dermis, hypodermis) or other keratinous tissue [i.e., hair (including hair follicles, hair roots, and hair bulbs), and nails (i.e., ventral epithelial layer of the nail bed)], as well as the sebaceous and perspiratory glands (eccrine and apocrine), which is intended to improve the condition and/or appearance of the skin, keratinous tissue, or sebaceous/perspiratory gland, or otherwise provide a skin health benefit.

"Topical" means the surface of the skin, other keratinous tissue, or sebaceous and perspiratory glands.

"Skin health benefit" means regulating and/or improving a skin condition, non-limiting examples of which include: improving the hydration status or moisturization of the skin; improving skin barrier function; improving skin appearance by reducing the appearance of one or more of fine lines and/or wrinkles, dyschromia, redness or blotches; imparting more even skin tone; increasing skin elasticity, resiliency or firmness; improving skin feel and texture by increasing smoothness or softness; reducing levels of inflammation; reducing degradation of extracellular skin matrix proteins; increasing the quantity and quality of extracellular skin matrix proteins; increasing the thickness of one or more layers of the skin.

"Dermatocosmetic products" (also referred to herein as "finished products") include but are not limited to, creams, moisturizers, lotions, ointments, gels, serums, color cosmetics (e.g., foundation, blush, lip stick/gloss, eye shadow, concealer), masks, and cleansers and washes, that may contain one or more active ingredients, including prescription and nonprescription pharmaceutical agents.

"Interesterified, non-fractionated triglyceride" means an ester formed from glycerol and three fatty acid groups that is transformed by "interesterification," a process involving the exchange of acyl radicals between (i) the triacylglycerol ester and an acid or

(ii) the triacylglycerol ester and an alcohol, and not further fractionated. The exchanges can be within the same triacylglycerol ester or between the triacylglycerol ester and a second ester, including another triacylglycerol ester. Interesterification is accomplished by techniques known in the art, altering the physical characteristics (molecular packing and melting points) of triglycerides, and generating more stable crystalline forms. "Petrolatum" means a purified mixture of semisolid hydrocarbons obtained from petroleum. In certain embodiments, the petrolatum contains both mineral oil,

microcrystalline and paraffin wax components and is further defined with references to the following properties: specific gravity (at 60°C) according to US Pharmacopeia ("USP") Physical Test 841 from 0.815 to 0.880; drop melting point according to ASTM International Standard D127from 38.0 to 75.0°C; consistency according to ASTM

International Standard D937 between 10-300 dmm (1/lOth of 1 mm = 1 dmm).

The term "petrolatum" is also to be understood in certain embodiments to include mineral oil (an oily liquid or tar-like hydrocarbonaceous material from a solid mineral source), a petroleum waxes (microcrystalline or paraffin), or a hydrocarbon produced from a non- petroleum source that has the following characteristics: specific gravity (at 60°C) according to US Pharmacopeia ("USP") Physical Test 841 from 0.815 to 0.880; drop melting point according to ASTM International Standard D127from 38.0 to 75.0°C; consistency according to ASTM International Standard D937 between 10-300 dmm (1/lOth of 1 mm = 1 dmm).

The multi-functional chemical ingredient of the present invention - also described in the application as a "multi-functional structured, glycidic / non-glycidic matrix" (referred to by the acronym "MFSG/NGM") - is comprised of or consists essentially of, or consists of, two component parts: (i) petrolatum(s) and (ii) and interesterified, triglyceride(s) that are non-fractionated and/or have a final melting point above or significantly above body temperature. In certain embodiments, the ingredient is described as a "structured glycidic / non-glycidic matrix" because the crystalline components of the interesterified, non-fractionated triglyceride(s) is/are oriented (i.e., "packed") with respect to

petrolatum(s) in a lower-energy, more stable configuration than a system comprised of non-interesterified triglyceride(s) and petrolatum(s). The nature of the structured glycidic / non-glycidic matrix can be more particularly described based on one or more analytical methods known in the art including, but not limited to, x-ray diffraction, differential scanning calorimetry (DSC), and scanning electron microscopy.

In certain embodiments, the petrolatum(s) in the MFSG/NGM meet(s) all current USP and FDA requirements (21 CFR §172.880).

In certain embodiments of the invention, the petrolatum part comprises USP-Grade White Petrolatum, a purified mixture of semisolid hydrocarbons obtained from petroleum that is wholly or nearly decolorized and may contain a stabilizer.

In preferred embodiments, the petrolatum part has the following physical properties: specific gravity at 60°C, per USP 841 of 0.815 - 0.880; drop melting point according to ASTM D127 between 51.6-60.0°C; consistency according to ASTM D937 between 170- 200 dmm; viscosity according to ASTM D445/D2161 between 40.0- 50.0 SUS @ 210°F; and Lovibond ® color of less than 1.0 yellow when measured according to Institute of Petroleum Standard Method IP 17. In certain preferred embodiments, the multi-functional, structured glycidic / non-glycidic matrix is present in a finished product at a concentration such that total petrolatum content is at least 30% on a weight/weight basis of the finished product.

In preferred embodiments, the triglyceride that is interesterified, non-fractionated is selected from the group consisting of Butyrospermum Parkii (Shea) Butter, Theobroma Cacao (Cocoa) Seed Butter, Shorea Stenoptera (Illipe) Seed Butter, Astrocaryum

Murumuru Seed Butter, Theobroma Grandiflorum (Capuacu) Butter and Magnifera Indigo (Mango) Seed Butter. (Interesterifed shea butter, cocoa butter and Illipe butter are available from AAK Sweeden AB and AAK USA Inc., as LIPEX ® Sheasoft, LIPEX ® Cocoasoft, and LIPEX ® Illipesoft.) The melting point of Lipex Sheasoft ® is about 51°C. The slope of the solid fat content (SFC) melting profile of LIPEX ® Sheasoft from 20°C to 35°C is less than 1, where percent change in SFC is plotted on the y axis, and temperature is plotted on the x axis.

In more preferred embodiments, the triglyceride that is interesterified, non-fractionated is selected from the group consisting of Butyrospermum Parkii (Shea) Butter, Theobroma Cacao (Cocoa) Seed Butter, and Shorea Stenoptera (Illipe) Seed Butter.

In one especially preferred embodiment, the triglyceride that is interesterified, non- fractionated is shea butter having from about 7% to about 10% unsaponifiables.

The unsaponifiable fraction of interesterified, non-fractionated shea butter is comprised of triterpene esters and highly unsaturated isoprenoidal hydrocarbons. Among the triterpene esters are cinnamic and acetic acid esters of a- and β-Amyrin, Butyrospermol, Lupeol, and Parkeol.

In especially preferred embodiments, the interesterified, non-fractionated shea butter contains at least about 2% triterpene esters; and, in even more preferred embodiments, the interesterified, non-fractionated shea butter contains from about 2% to about 5% triterpene esters; and in still more preferred embodiments above about 5% triterpene esters. In a first non-limiting aspect of the invention, the petrolatum component and the interesterified, non-fractionated ester component are combined to form a multi-functional structured, glycidic / non-glycidic matrix that is thermostable in comparison to petrolatum. "Thermostable" means that the Solid Fat Content (SFC) of the MFSG/NGM of the present invention is within about 3% of the SFC of petrolatum at the same temperature. Comparing the areas under the respective melting profile curves between 20°C and 45°C of the two materials further demonstrates that the MFSG/NGM

embodiments of the present invention is equivalently thermostable to petrolatum - within about one percent (1.3%). The area under the melting profile curve of petrolatum (20°C - 45°C) is 137; the area under the melting profile curve of the MFSG/NGM of the present invention (25% interesterified, non-fractionated shea butter; 75% petrolatum) is 138.8. In contrast, the area under the melting profile curve of a blend of 25% non-interesterified (i.e., RBD) shea butter and 75% petrolatum is 101.62; this represents an over 25% difference (25.82%). Table 1 below presents the SFC and area under the curve over a temperature range from 20°C to 45°C of a topically-applied product according to the present invention that is a mixture of 25% interesterified, non-fractionated shea butter and 75% of petrolatum.

In preferred embodiments of the first aspect of the invention, the thermostable

MFSG/NGM is a binary, homogenous mixture of one or more interesterified, non- fractionated triglyceride(s) and petrolatum(s) in the following ratios: 1:39; 1:38; 1:37; 1:36; 1:35; 1:34; 1:33; 1:1:32; 1:31; 1:30; 1:29; 1: 28; 1:27; 1:26; 1:25; 1:24; 1:23; 1:22; 1:21; 1:20; 1:19; 1:18; 1:17; 1:16; 1:15; 1:14; 1:13; 1:12; 1:11; 1:10; 1:9; 1:8; 1:7; 1:6; 1:5; 1:4; 1:3; 1:2; or 7:13. In preferred embodiments of the first aspect of the invention, the interesterified, non- fractionated triglyceride(s) is/are present at a concentration of from about 2% to about 50% by weight of the thermostable MFSG/NGM; from about 2.5% to about 35% by weight of the thermostable MFSG/NGM; from about 5% to about 25% by weight of the thermostable MFSG/NGM; or from about 10% to about 20% by weight of the

thermostable MFSG/NGM .

In more preferred embodiments of the first aspect of the invention, interesterified, non- fractionated triglyceride(s) is at least 10% by weight of the thermostable MFSG/NGM, but not more than 35% by weight of the thermostable MFSG/NGM. In one highly preferred embodiment of the first aspect of the invention, the

interesterified, non-fractionated triglyceride is shea butter, which is present at a concentration of greater than 2%, more preferably greater than 2.5%, but less than 35% by weight of the thermostable MFSG/NGM.

The thermostable MFSG/NGM embodiments are "multi-functional", providing multiple skin health benefits (as defined above).

In certain embodiments of the present invention, it was surprisingly and unexpectedly found that while the MFSG/NGM of the invention had substantially the same physico- sensory properties as "neat" petrolatum (i.e., petrolatum without the addition of interesterified, non-fractionated shea butter), at four hours post-application to the skin the MFSG/NGM of the invention provided a reduction in transepidermal water loss and greater improvement in skin barrier function versus neat petrolatum.

By the phrase "substantially the same physico-sensory properties as 'neat' petrolatum" is meant, a difference of less than 5% from neat petrolatum in sensory panel test that measures seven parameters on a scale of 0 - 5, where neat petrolatum is assigned as score of 3. The seven parameters are spreadability; greasiness; cushion; tack; absorption; gloss; and graininess.

A second non-limiting aspect of the invention is directed to a multifunctional, skin barrier protecting dermatocosmetic product comprising the MFSG/NGM described in the first aspect of the invention, where the product does not separate, or exhibit bloom, graininess (sometimes also referred to as "sandiness") or discernible change in viscosity during the established shelf life of the product, as perceived by a trained observer/technician or instrumentally using analytical techniques known to the skilled artisan in the field. "Bloom" occurs when two crystalline materials are mixed, and unstable crystals form. Bloom is visible to the naked eye, and can manifest as a coating on the surface of the product.

"Graininess" is a tactile property that can be perceived when a product is applied (e.g., rubbed) onto the skin. A change in viscosity is determined instrumentally. The viscosity of a product is measured with the same type of viscometer (e.g., Brookfield RVT) configured with the same type of spindle (spindle number 4) at the same rotation speed (RPM) as specified in a certificate of analysis for the product.

In the case of a dermatocosmetic product comprising the MFSG/NGM of the present invention that is an emulsion, stability (i.e., not separating into oil and water phases) may be assessed as follows. Glass jars and, preferably, finished packaging (i.e., packaging in which the product is planned to be sold to consumers) are filled with the product. The filled containers (glass jars and finished packaging) are stored at different temperatures and under different light conditions for time periods of varying lengths. Temperatures include 50°C, 45°C, 37°C, 25°C (often described in the art as "room temperature"), and 4°C. Different lighting conditions may include fluorescent light and light emitted from a solar simulator, a device that provides illumination approximating natural

sunlight. Preferably, the solar simulator is calibrated and operated in accordance with the criteria set out int the following standards: ASTM E927-10(2015) published by ASTM International (West Conshohocken, Pennsylvania); or Standard IEC 60904-9 Edition2 published by the International Electrotechnical Commission (Geneva, Switzerland). If the product is a sunscreen, the solar simulator will comply with the then current standard promulgated by the applicable governmental or industry body: in the United States, the Food and Drug Administration; in Europe, the European Cosmetics Association (COLD 3 A); in Japan, Japan Cosmetics Industry Association (JCIA). Samples can, and preferably, are evaluated at the following time intervals: 2 weeks, 4 weeks, 8 weeks, 12 weeks. Additionally, samples stored at evaluated at 25°C, 37°C and 4°C are evaluated after one year. The highest temperature samples and the light exposed samples are preferably evaluated for the first three test intervals. Before testing, samples are preferably kept at room temperature for about 8 hours to equilibrate.

Separation of emulsion embodiments of the invention may occur over days or weeks. Appearance of bloom or change in color (discoloration) or developing a sandy or grainy texture may likewise occur over days or weeks. A third, non-limiting aspect of the invention is directed to a multifunctional, skin barrier protecting dermatocosmetic product that does not exhibit bloom, graininess or discernable change in viscosity during the established shelf life of the product, as perceived by a trained observer/technician or instrumentally using analytical techniques known to the skilled artisan in the field, where the product comprises a moisturizing amount of petrolatum - e.g., at least 3% by weight of the product;

preferably at least 5% by weight of the product; still more preferably at least 10% by weight of the product; and even more preferably at least 30% by weight of the product - and one (or a combination of) triglyceride butter(s) at a concentration of at least 2%. In preferred embodiments, the triglyceride butter(s) are interesterified, non-fractionated. In one preferred embodiment of the third aspect of the invention, the dermatocosmetic product is comprised of (i) at least 2%, preferably at least 5%, and still more preferably at least 10%) of an interesterified, non-fractionated triglyceride and (ii) at least 5%, preferably at least 10%, and still more preferably at least 30% of a petrolatum. An especially preferred interesterified, non-fractionated triglyceride is shea butter. Formulas containing the topical product or MFSG/NGM of the invention may also contain additional ingredients and function as a "topical delivery system" that deposits a wide range of cosmetic and dermatologic ingredients, include prescription active pharmaceutical agents and non-prescription drugs to the skin for purposes of providing a skin health benefit, as well as systemically through the skin.

Testing Examples Improved Skin Barrier Function (TEWL)

Ten female subjects, ages 36-58, were enrolled and completed a clinical study to evaluate the efficacy of topical product comprising the Dermatocosmetic Structured Glycidic / non-glycidic Matrix of the present invention in improving skin barrier function.

Transepidermal water loss (TEWL), a measure of skin barrier function, was measured using DermaLab Evaporimeter (Cortex Technology, Hadsund, Denmark). An absence of change in TEWL at post-treatment intervals compared to baseline is indicative that the treatment had not disturbed barrier function. A decrease in TEWL indicates an improvement in skin barrier function (i.e., less water is lost through the skin barrier).

For a "washout" period of at least three days prior to commencement of the study, subjects used a neutral soap bar for cleansing (i.e. bathing) the test sites - namely, the volar surface of forearms of their forearms. Subjects were instructed not to use of any personal care products (e.g., lotions, creams, cleansers) except for those provided by the test facility.

Subjects returned to the test site facility following the washout period. As instructed, subjects wore clothing that did not cover their forearms. The volar surface of the forearms were gently wiped with a damp disposable washcloth and patted dry with a paper towel by trained staff. Staff then marked four test sites on the volar surfaces of the forearms - two sites on one forearm; two sites on the other forearm. Each test site was 4cm X 4cm; adjacent test sites were separated by at least 3cm. Test sites were placed at least 2cm from the wrist joint and at least 2cm from elbow joint, and were identified as Test Sites 1-4. Designation of test vs. untreated (control) sites was random. Next, subjects equilibrated for first time for a minimum of thirty minutes in a room maintained at approximately 22 ±2°C and 40 ± 10% relative humidity. (Temperature and humidity was verified and recorded throughout the study - before and after equilibration, and before each TEWL measurement.)

Following equilibration, baseline TEWL readings were taken at each test site by trained staff using an Evaporimeter. Approximately 2 mg/cm 2 of the test product (the dermatocosmetic product according to Formulation Example 1) was then pipetted directly onto the sites and rubbed in gently using a fingercot. (The fingercot was examined after application to ensure that the majority of the test material does not adhere to the fingercot.) Subjects were sequestered at the testing facility for the remainder of the study visit.

During this time, subjects were instructed to keep their volar forearms uncovered/exposed and were not allowed to cover, wet or wipe the test sites.

At 3 hours and 30 minutes post-treatment (± 10 minutes), subjects equilibrated for a second time under the above conditions. Following equilibration (4 hours ± 10 minutes post treatment), TEWL readings were taken as described above. At 7 hours and 30 minutes post-treatment (± 10 minutes), subjects equilibrated for a third and final time. Following equilibration (8 hours ± 10 minutes post treatment), TWEL measurements were made. Subjects were dismissed after the 8 hour measurements had been completed.

Sites to which the test product was applied demonstrated statistically significantly better skin barrier function than the control untreated sites when compared to baseline after 4 hours.

Sensory Panel An eight person panel compared the MFSG/NGM of the present invention (25% interesterified, non-fractionated shea butter + 75% petrolatum) with (i) a blend of 25% RBD shea butter and 75% petrolatum and (ii) "neat" petrolatum. The same grade of petrolatum was used in all three products - namely White Protoline ® Petrolatum available from Sonneborn, LLC (Parsippany, NJ). The sensory evaluation was performed on the basis of spreadability, greasiness, cushion, tack, absorption, gloss, and graininess.

Ratings for each parameter were assessed based on a 5 -point system, with neat Protoline ® being assigned a score of "3".

Skin firmness is measured using the Cutometer ® . An increase in Cutometer ®

measurements is observed after using the dermatocosmetic product according to

Example 1, indicating improvement (increase) in skin firmness.

Skin flakiness is measured by using D-Squame® Skin Surface Sampling Discs (CuDerm Corporation, Dallas, TX). A clear adhesive disc is applied to clean, dry skin prior to step 2. The disc is pressed firmly to the skin for several seconds, then removed from the skin. Before and after D-Squame® scores are assigned based on the following scale: 1 = very slight flakiness; 2 = mild flakiness; 3 = moderate flakiness; 4 = marked flakiness; 5 = severe flakiness. A decrease in D-Squame ® score indicates an improvement (decrease) in flaky skin; an increase in D-Squame ® score represents worsening of flakiness. Skin firmness is measured using the Cutometer . An increase in Cutometer

Subjects exhibiting signs of skin aging - uneven skin tone/texture (brown patches, erythema) and visible facial fine lines and wrinkles - are recruited to participate in a clinical study to assess the effectiveness of dermatocosmetic products according to the invention in improving the appearance of these signs of skin aging. Digital images of the face are taken before and after practicing the method of the present invention. The images are captured, processed and analyzed using the VISIA ® CR Imaging System (Canfield Scientific, Inc. Fairfield, NJ). Each image is scanned horizontally and vertically; the intensity of red, green and blue pixels are determined using the proprietary VISIA ® CR mathematical algorithms, and a texture score is assigned. The same algorithms calculate the number and depth of fine lines and wrinkles.

Decreases in texture score and the wrinkle/line count and depth are observed, representing an improvement in these skin aging parameters. Skin Barrier Function Testing

TEWL was measured using a TEWL Probe - a DermaLab ® Evaporimeter (Cortex Technology, Hadsund, Denmark). Decreases in TEWL indicate an improvement in skin barrier function, such that less water is lost through the skin barrier.

Subjects were arrived at the test facility three days prior to the scheduled start date, and were enrolled per inclusion and exclusion criteria. Subjects received a "neutral" soap bar (Neutrogena) to use for cleansing (i.e. bathing) their volar forearms (which would serve as the test sites) for a 3 -day washout period. Subjects were given specific instructions prohibiting use of all personal care products (e.g., lotions, creams, cleansers) on the test sites (volar forearms) for the entirety of the study, except for products provided by the test facility.

Following the washout period, subjects returned to the testing facility. Subjects were instructed to wear clothing that did not cover their volar forearms on the evaluation day. The surface of the volar forearms was gently wiped with a damp disposable washcloth and patted dry with a paper towel by trained staff. Staff then marked six (6) test sites on the volar surfaces of the forearms (three sites on each forearm). Each test site was 4 cm x 4 cm. Test sites were placed centrally on the volar forearms (at least 2c m from the wrist and at least 2 cm from elbow) and identified at Test Sites A-F. The treatment sites and control sites (untreated) were randomly assigned using a computer generated

randomization code. Measurements were made with the TEWL Probe within these test sites throughout the study period.

Prior to measurement, subjects underwent an equilibration prcess in which they remained quietly seated for a minimum of twenty (20) minutes in a room maintained at 20-24°C and 30-50% relative humidity. During this time, subjects were instructed to keep their volar forearms uncovered/exposed by resting their hands, palms up, on their thighs.

Packaging tape was applied to the tape-stripped treated sites and control (untreated) sites. TEWL readings (by Evaporimeter) were performed and repeat tape stripping were made on the test sites until a TEWL measurement greater than 20 g/m 2 /h was reached. Following baseline measurements (post-tape stripping), test products - MFSG/NGM of the present invention (identified in the table below as "SF£EA XP") and "neat petrolatum" - were each applied (pipetted) onto the designated test sites at a concentration of

2mg/cm 2 , and rubbed into the skin by stagg using a fingercot until fully absorbed. (The fingercot was examined after application to ensure that the test material did not adhere to the fingercot. One site served as a control (untreated).

For the duration of a 12-hour study period, subjects were sequestered in a temperature and humidity controlled room at the testing. Subjects were instructed to keep their volar forearms uncovered/exposed. Subjects were not allowed to cover, wet or wipe their volar forearms until dismissed from the testing. No eating or drinking was allowed 30 minutes prior to a measurement being performed.

At 3 hours and 30 minutes post-treatment (± 10 minutes), subjects equilibrated by remaining quietly seated for a minimum of 20 minutes in a room maintained at approximately 20-24°C and 30-50% relative humidity. TEWL measurement were taken at 4 hours (± 10 min) post-treatment. At 7 hours and 30 minutes post-treatment (± 10 minutes), subjects again equilibrated by remaining quietly seated for a minimum of 20 minutes in a room maintained at approximately 20-24°C and 30-50% relative humidity. TEWL measurement were taken at 8 hours (± 10 min) post-treatment. At 11 hours and 30 minutes post-treatment (± 10 minutes), subjects equilibrated by remaining quietly seated for a minimum of 20 minutes in a room maintained at approximately 20-24°C and 30-50%) relative humidity. TEWL measurement were taken at 11 hours (± 10 min) post-treatment.

Following the measurements over an initial 12-hour period, subjects were dismissed from the testing facility and were instructed to return approximately 23 hours and 30 minutes (±30 minutes) post-application. Subjects were instructed not to wet (i.e., no showering, bathing or swimming) or apply products to their volar forearms until after the 24 hour measurements. At 23 hours and 30 minutes post-treatment (± 30 minutes), subjects equilibrated by remaining quietly seated for a minimum of 20 minutes in a room maintained at approximately 20-24°C and 30-50%> relative humidity. TEWL

measurement were taken at 24 hours (± 30 min) post-treatment. Subjects were dismissed after 24 hour post-treatment measurements were obtained.

There was a directional improvement in TEWL using Shea XP vs. neat petrolatum, ranging from 2.25% to 2.69%>, within an almost 3% directional improvement at 12 hours post-application.
