[0010] This disclosure relates to cosmetic or skin pharmaceutical compositions containing ingredients for the care of skin, mucous membranes and skin appendages, and in some instances for the prevention of signs of endogenous and / or extrinsic aging.

[0011] Skin, mucous membranes, and skin appendages are among the most vulnerable elements. In fact, the balance of skin, mucous membranes, and skin appendages is permanently disrupted by external aggressors, sunlight, wind, and cold. Skin aging is one of the earliest signs of external aging. Skin aging is caused by a certain amount of deterioration that occurs spontaneously over time, but it can also be caused by external factors (solar radiation, tobacco smoke, excessive alcohol consumption).

[0012] Clinically, signs of aging are caused by the appearance of wrinkles and fine lines, and the loosening of the skin and subcutaneous tissue. This results in dull skin texture, loose skin with fine lines, reduced skin firmness, loss of elasticity and overall flaking, dull skin and a lack of freshness in skin tone.

[0013] Aging also causes a decrease in the amount, thickness, and growth of hair, a decline in secretions (sebum and sweat), and a deterioration in the structure and growth of nails. Hyperpigmented or hypopigmented spots are frequently observed in parts of the skin exposed to the sun throughout life—primarily the face, under the neck, hands, and forearms.

[0014] Some of these signs are more specifically associated with inherent or physiological aging, i.e., age-related aging, while others are more specific to extrinsic aging, i.e., aging usually caused by the environment; more particularly related to photoaging caused by exposure to the sun, light, or any other radiation.

[0015] The various applications described herein relate to a cosmetic composition that can be used as a topical skin composition. For example, the cosmetic composition may be a face cream. More specifically, the cosmetic composition may be used as a cream applied to the skin near a user's eyes. The cosmetic composition may reduce the appearance of wrinkles in the area of ​​skin to which it is applied.

[0016] The cosmetic composition is in the form of an emulsion. Emulsions are typically oil-in-water emulsions. In addition to the ability of the cosmetic composition to reduce the appearance of wrinkles, the cosmetic composition has additional beneficial properties. For example, the cosmetic composition exhibits commercially acceptable stability. A cosmetic composition is considered stable if it does not separate from its constituent parts. For example, the cosmetic composition demonstrates stability for at least 8 weeks after continuous exposure to temperatures ranging from about 30°C to about 50°C, from about 37°C to about 45°C, less than, equal to, or greater than about 30°C, 31°C, 32°C, 33°C, 34°C, 35°C, 36°C, 37°C, 38°C, 39°C, 40°C, 41°C, 42°C, 43°C, 44°C, 45°C, 46°C, 47°C, 48°C, 49°C, or about 50°C. Therefore, the cosmetic composition can be stored and remains usable for a period of time. Achieving the disclosed stability may be related to the ratio of thickener to stabilizer as described herein.

[0017] Cosmetic compositions are also capable of maintaining an acceptable pH. For example, when measured at least 2 months after manufacture, the pH of the composition can be in the range of about 5 to about 6, about 5.1 to about 5.7, less than, equal to or greater than about 5, 5.1, 5.2, 5.3, 5.4, 5.5, 5.6, 5.7, 5.8, 5.9 or about 6. The pH of a cosmetic composition can significantly affect its performance and stability. Therefore, the ability of a cosmetic composition to maintain an acceptable pH for a sufficient amount of time enhances its ability to become a commercially viable product. The pH ranges described herein help allow for the disclosed ratio of thickener to stabilizer.

[0018] Furthermore, the viscosity of the cosmetic composition can be controlled and maintained within a suitable range. For example, the viscosity of the cosmetic composition measured 24 hours and 2 months after manufacturing is in the range of about 30,000 cps to about 80,000 cps, 40,000 cps to about 70,000 cps, less than, equal to, or greater than about 30,000 cps, 35,000 cps, 40,000 cps, 45,000 cps, 50,000 cps, 55,000 cps, 60,000 cps, 65,000 cps, 70,000 cps, 75,000 cps, or about 80,000 cps. Viscosity is measured at 25°C using Brookfield RVT E / 20. The viscosity of the cosmetic composition allows it to be spreadable without flowing or dispersing too quickly. Furthermore, the confirmation that the viscosity remained within the aforementioned range after two months indicates that the viscosity is stable and does not rapidly rise or fall above the stated range. Viscosity can be partially controlled by the thickener to stabilizer ratio disclosed herein.

[0019] The aforementioned properties arise from the components of the cosmetic composition. While not limited thereto, the cosmetic composition includes water, emulsifiers, thickeners, and active ingredients. Emulsifiers may include any number of components capable of forming a water-in-oil composition. A particularly suitable emulsifier is PEG-40 stearate. PEG-40 stearate is a synthetic polymer composed of PEG (polyethylene glycol) and stearic acid (a naturally occurring fatty acid). PEG-40 stearate may also be referred to as MACROOGL STEARATE 2000, POLYETHYLENE GLYCOL 2000 MONOSTEARATE, POLYOXYETHYLENE (40) MONOSTEARATE, POLYOXYLENE 40 STEARATE, and STEARETHATE 40.

[0020] Thickeners may include any amount of suitable thickeners to help achieve a desired viscosity value. For example, thickeners may include a mixture of sodium acrylate copolymers and lecithin. Sodium acrylate copolymers are sodium salts of polymers consisting of one of acrylic acid, methacrylic acid, or simple esters thereof. Acrylic esters belong to the family of polymers of the vinyl polymer type. Synthetic chemicals are used in the manufacture of plastics, coating formulations, and other products. Acrylic ester copolymers are a general term for copolymers of two or more monomers consisting of one of acrylic acid, methacrylic acid, or simple esters thereof. Sodium acrylate copolymers are also known as acrylamide / sodium acrylate copolymers; 2-acrylamide, a polymer having a sodium salt of 2-propionic acid; 2-propionic acid, a polymer having 2-acrylamide; 2-acrylamide-sodium 2-propionate copolymers; sodium acrylate acrylamide polymers; sodium acrylate-acrylamide copolymers. Lecithin typically includes a mixture of glycerophospholipids, including phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol, phosphatidylserine, and phosphatidic acid. Lecithin may be derived from soybeans. Lecithin derived from soybeans may include about 33 wt% to about 35 wt% soybean oil, about 20 wt% to about 21 wt% phosphatidylinositol, about 19 wt% to about 21 wt% phosphatidylcholine, about 8 wt% to about 20 wt% phosphatidylethanolamine, about 5 wt% to about 11 wt% other phospholipids, about 5 wt% free carbohydrates, about 2 wt% to about 5 wt% sterols and about 1 wt% water.

[0021] The emulsifier is present in the oil phase of the emulsion, and the thickener is present in the aqueous phase of the emulsion. The wt:wt ratio of the emulsifier to the thickener relative to each other is in the range of about 5:1 to about 1.5:1, about 5:4 to about 5:2, or about 5:3 to about 5:2.

[0022] Active blends comprise a mixture of components that work together on the user's skin. Specifically, active blends can be used to reduce wrinkles, hydrolyze the skin, etc. For example, an active blend may include kombucha; a mixture of thermophilic thermophilic ferment and glycerin; and α-glucan oligosaccharides. Kombucha (also known as tea mushroom, tea fungus, or Manchurian mushroom; Latin name Medusamyces gisevii) is a fermented, slightly effervescent, sweetened black tea beverage. Thermophilic thermophilic ferment is a natural byproduct of the fermentation of thermophilic bacteria, a bacterium that can live thousands of feet below the ocean surface. On the skin, this special ferment helps protect the skin's supporting structure from destructive enzymes and helps maintain a firm feel. The ferment also has antioxidant capabilities, particularly against the rogue molecules formed during fatty acid breakdown. The free radical scavenging ability of thermophilic thermophilic bacteria has been compared to strong antioxidants in the skin, such as superoxide dismutase. It is an excellent source of alpha-galactosidase, an enzyme that helps replenish glycoproteins, which skin needs to look healthier. Alpha-glucan oligosaccharides are natural prebiotics that help support a healthy microbiome. When the skin's microbiome (its invisible barrier) is disrupted, harmful bacteria can proliferate because it is not controlled by the healthy flora on the surface. This can potentially trigger signs of irritated and sensitive skin. Alpha-glucan oligosaccharides also have antioxidant benefits, helping to reduce the visible effects of oxidative stress on the skin.

[0023] Kombucha may be present in the cosmetic composition in the range of about 1 wt% to about 5 wt%, about 2 wt% to about 4 wt%, less than, equal to or greater than about 1 wt%, 1.5 wt%, 2 wt%, 2.5 wt%, 3 wt%, 3.5 wt%, 4 wt%, 4.5 wt%, or about 5 wt%. The mixture of thermophilic bacteria ferment and glycerin may be present in the cosmetic composition in the range of about 1 wt% to about 10 wt%, about 3 wt% to about 7 wt%, less than, equal to or greater than about 1 wt%, 1.5 wt%, 2 wt%, 2.5 wt%, 3 wt%, 3.5 wt%, 4 wt%, 4.5 wt%, 5 wt%, 5.5 wt%, 6 wt%, 6.5 wt%, 7 wt%, 7.5 wt%, 8 wt%, 8.5 wt%, 9 wt%, 9.5 wt%, or about 10 wt%. α-Glucan oligosaccharides may be present in cosmetic compositions in the range of about 0.1 wt% to about 5 wt%, about 0.5 wt% to about 3 wt%, less than, equal to or greater than about 0.1 wt%, 0.5 wt%, 1 wt%, 1.5 wt%, 2 wt%, 2.5 wt%, 3 wt%, 3.5 wt%, 4 wt%, 4.5 wt% or about 5 wt%. In total, the active mixture may be in the range of about 1 wt% to about 15 wt%, about 5 wt% to about 10 wt%, less than, equal to or greater than about 1 wt%, 1.5 wt%, 2 wt%, 2.5 wt%, 3 wt%, 3.5 wt%, 4 wt%, 4.5 wt%, 5 wt%, 5.5 wt%, 6 wt%, 6.5 wt%, 7 wt%, 7.5 wt%, 8 wt%, 8.5 wt%, 9 wt%, 9.5 wt%, 10 wt%, 10.5 wt%, 11 wt%, 11.5 wt%, 12 wt%, 12.5 wt%, 13 wt%, 13.5 wt%, 14 wt%, 14.5 wt%, or about 15 wt% of the cosmetic composition. The active mixture is located in the aqueous phase.

[0024] The aqueous and oil phases may include other components. For example, the oil phase may further include sheabutter, pentaerythritol tetraethylhexanoate, triglycerides, behenol, glyceryl stearate, or mixtures thereof. The aqueous phase may further include glycerin, xanthan gum, or mixtures thereof. When present, sheabutter may be present in the range of about 1 wt% to about 10 wt%, about 3 wt% to about 7 wt%, less than, equal to, or greater than about 1 wt%, 2 wt%, 3 wt%, 4 wt%, 5 wt%, 6 wt%, 7 wt%, 8 wt%, 9 wt%, or about 10 wt% of the cosmetic composition. When present, pentaerythritol tetraethylhexanoate may be present in the range of about 1 wt% to about 8 wt%, about 2 wt% to about 5 wt%, less than, equal to, or greater than about 1 wt%, 2 wt%, 3 wt%, 4 wt%, 5 wt%, 6 wt%, 7 wt%, or about 8 wt% of the cosmetic composition. When present, triglycerides may be present in the range of about 1 wt% to about 10 wt%, about 2 wt% to about 8 wt%, less than, equal to, or greater than about 1 wt%, 2 wt%, 3 wt%, 4 wt%, 5 wt%, 6 wt%, 7 wt%, 8 wt%, 9 wt%, or about 10 wt% of the cosmetic composition. When present, behenol may be present in the range of about 1 wt% to about 5 wt%, about 2 wt% to about 4 wt%, less than, equal to, or greater than about 1 wt%, 2 wt%, 3 wt%, 4 wt%, or about 5 wt% of the cosmetic composition. When present, glyceryl stearate may be present in the range of about 1 wt% to about 5 wt%, about 2 wt% to about 4 wt%, less than, equal to, or greater than about 1 wt%, 2 wt%, 3 wt%, 4 wt%, or about 5 wt% of the cosmetic composition.

[0025] Table 1 below provides specific examples of cosmetic formulations according to this disclosure. Table 1 provides the concentration (wt%), INCI name, and CAS number (if available) for each component.

[0026] Table 1:

[0027]

[0028] The cosmetic compositions described herein can be produced according to many suitable methods. For example, water, emulsifiers, thickeners, and active ingredients can be simply mixed together and left to stand for a period of time to form a cosmetic composition.

[0029] Cosmetic compositions can be applied in any suitable manner. For example, a cosmetic composition can be applied topically to a user's skin. A cosmetic composition can be applied topically by hand, with an applicator, or both. Examples of applicators include brushes, powder puffs, sponges, etc.

[0030] Example

[0031] The various embodiments of the present invention can be better understood by referring to the following examples, which are provided as illustrative purposes. The present invention is not limited to the examples given herein.

[0032] friction

[0033] The friction of the composition described herein will be determined using a texture analyzer. The texture analyzer will be an LS1 machine available from Ametek, Berwyn, PA. A 15 ml sample of the composition will be loaded onto the sample tray of the texture analyzer. A spatula will be used to form a uniform layer of the composition. A wire with a metal weight attached will be placed at the far end of the tray. The texture analyzer will pull the wire to drag the metal weight across the surface of the composition. The texture analyzer will record the force required to move the weight, and the measured force will be used to determine the friction of the composition.

[0034] It is expected that most participants evaluating the composition will find it comfortable when applied to the skin. Further, it is anticipated that friction on the composition will allow it to prevent it from flowing to an undesirable extent after application.

[0035] Penetrate and pick up

[0036] The penetration and pick-up assessments of the compositions described herein will be determined using a texture analyzer. The texture analyzer will be an LS1 machine available from Ametek Corporation in Berwin, Pennsylvania. To determine these values, a sample cup will be filled with 100 ml of the composition. A spatula will be used to spread the composition and form a uniform layer. The probe of the texture analyzer will be lowered into the composition. The force required to lower into the composition will be measured, and this force will be the penetration value. After lowering, the probe will rise, and the force required will be measured as the pick-up value. The higher the load (force) required to penetrate the sample, the stronger the structure of the sample, and therefore the thicker the sample will feel (the more resistant it is to being penetrated). The higher the load required to remove the probe from the sample, the more adhesive the user will perceive.

[0037] It is anticipated that most participants evaluating the composition will find it comfortable when applied to the skin. Further, it is expected that the composition's penetration and pickup will allow it to not flow to undesirable levels after application.

[0038] Spreadability

[0039] The spreadability of the compositions described herein will be determined using a texture analyzer. The texture analyzer will be an LS1 machine available from Ametek Corporation in Berwin, Pennsylvania. 50 ml of the composition will be placed in a sample cup. A spatula will be used to spread the composition into a uniform layer. A conical probe will be lowered into the composition, and the force required to spread the product against the walls of the conical probe will be recorded to measure the spreadability of the composition. The higher the energy required to extend the machine, the more rigid the composition structure, and therefore the less spreadable the composition.

[0040] It is expected that most participants evaluating the composition will find it comfortable when applied to the skin. Further, it is anticipated that measurements of the composition's spreadability will allow it to not flow to an undesirable extent after application.

[0041] Other sensory attributes

[0042] A group of consumers will be asked to evaluate several properties of the composition before, during, and after application. Table 1 provides the categories to be evaluated (e.g., appearance, texture, odor), their definitions, protocols, and the scales that panel members will be asked to use for the evaluation. It is expected that the tested compositions will receive acceptable scores from a majority of panel members.
