Description

[Technical Field]

[0001] The present invention relates to a cosmetic product containing a cosmetic composition contained in an applicator, wherein the cosmetic composition contains about 2% to about 20% of an endothermic material selected from the group consisting of sugar alcohols, disaccharides, and mixtures thereof, and the endothermic material has an endothermic value of 5 cal / g or more when dissolved in water, and the applicator comprises an application surface for applying the cosmetic composition, the application surface comprising ceramic and / or metal, and a reservoir having an opening fluidically connecting the application surface to the reservoir. The cosmetic product of the present invention provides a moisturizing feeling while maintaining a moderate cooling sensation during and after application. [Background technology]

[0002] Mammalian keratinous tissue, particularly human skin, is subject to various damages caused by both exogenous and endogenous factors. Such exogenous factors include ultraviolet light, environmental pollution, wind, heat, infrared rays, low humidity, harsh surfactants, abrasives, etc. Meanwhile, endogenous factors include chronological aging and other biochemical changes within the skin. Whether exogenous or endogenous, these factors result in visible signs of skin damage. Typical skin damage in aged or damaged skin includes fine lines, wrinkles, hyperpigmentation, pale skin, sagging, dark circles under the eyes, puffy eyes, enlarged pores, a slow turnover rate, and abnormal desquamation or peeling. Additional damage caused by both exogenous and endogenous factors includes visible necrotic skin, i.e., peeling, flaking, dryness, and roughness.

[0003] Currently, there are several personal care products available to consumers that are aimed at improving the health and physical appearance of keratinous tissues such as skin, hair, and nails.Most of these products are aimed at delaying, minimizing, or even eliminating skin wrinkles, age spots, and other histological changes that are typically associated with skin aging or environmental damage to human skin.Consumers prefer topically applied products because they are not only effective, but also safe and comfortable to use.

[0004] Some cosmetic compositions are provided with applicators for delivering the above benefits to target areas of the skin, for example, eye care products.

[0005] Some cosmetic products are known that provide a cooling sensation during application of the product. The cooling sensation can be provided by the cosmetic composition. Alternatively, the cooling sensation can be provided by the applicator, for example, from heat transfer from the skin to its metallic application surface.

[0006] Menthol and its derivatives are known to provide a cooling sensation when included in a cosmetic composition. However, this cooling sensation may be too strong for some users and / or users who apply such compositions to sensitive areas of the skin, such as the facial skin around the eyes. Ethanol is also known to provide a cooling and / or refreshing sensation when included in a cosmetic composition. However, it may be difficult to provide a long-lasting cooling and / or refreshing sensation from ethanol. Ethanol may also cause a dry sensation and / or reduce moisturizing sensation. Summary of the Invention [Problem to be solved by the invention]

[0007] Based on the above, there is a need for a cosmetic product that provides a moisturizing feel while also providing a moderate cooling sensation during and after application for an extended period of time. [Means for solving the problem]

[0008] The present invention relates to a cosmetic product comprising a cosmetic composition contained in an applicator, The cosmetic composition comprises about 2% to about 20% of an endothermic material selected from the group consisting of sugar alcohols, disaccharides, and mixtures thereof, the endothermic material having an endothermic value of 5 cal / g or more when dissolved in water; The applicator comprises an application surface for applying the cosmetic composition, the application surface comprising ceramic and / or metal, and a reservoir having an opening fluidly connecting the application surface to the reservoir.

[0009] Surprisingly, it has been found that by using a specific heat-absorbing material in conjunction with a specific application surface, the cosmetic product of the present invention provides a moisturizing sensation while maintaining a moderate cooling sensation during and after application. The cosmetic product of the present invention provides such a long-lasting, suitable cooling sensation at ambient temperature without the need for refrigeration or external cooling.

[0010] Unlike menthol, which provides a cooling sensation through sensory receptor activation (TRPM8), certain endothermic materials provide a suitable cooling sensation when combined with certain application surfaces. Also, unlike ethanol, which provides a cooling sensation through the evaporation of ethanol, certain endothermic materials provide a prolonged cooling sensation, especially when combined with certain application surfaces.

[0011] It is known that endothermic materials can provide a cooling sensation when dissolved in water.Without being bound by theory, it is believed that certain endothermic materials in the present composition are at least partially solidified during application due to the evaporation of the aqueous carrier in the composition, and then the solidified endothermic material is dissolved in the moisture of skin, sweat, and / or the remaining aqueous carrier from the composition on the skin surface.In addition, it is believed that certain application surfaces, particularly rolling balls, can accelerate the evaporation of the aqueous carrier of the composition, and therefore provide a cooling sensation at an earlier time of application.

In one embodiment, the carrier is present in a concentration of about 50% to about 99%, about 60% to about 98%, about 70% to about 98%, or alternatively about 80% to about 95% by weight.

[0050] The carrier may be in a wide variety of forms. In some cases, the form and characteristics of the carrier may be determined by the solubility or dispersibility of the components (e.g., extracts, sunscreen actives, additional ingredients). Non-limiting examples include simple solutions (e.g., aqueous or anhydrous), dispersions, emulsions, and solid forms (e.g., gels, sticks, flowable solids, or amorphous materials). In some cases, the dermatologically acceptable carrier is in the form of an emulsion. Emulsions may have a continuous aqueous phase (e.g., oil-in-water or water-in-oil-in-water emulsions) or a continuous oil phase (e.g., water-in-oil or oil-in-water-in-oil emulsions). The oil phase of the present invention may include non-silicone oils such as silicone oils, hydrocarbon oils, esters, ethers, and mixtures thereof. The aqueous phase typically includes water and water-soluble ingredients (e.g., water-soluble moisturizers, conditioning agents, antibacterial agents, humectants, and / or other skin care actives). However, in some cases, the aqueous phase may include components other than water, including, but not limited to, water-soluble moisturizers, conditioning agents, antimicrobial agents, humectants, and / or other water-soluble skin care actives. In some cases, the non-water components of the composition include humectants, such as glycerin and / or other polyol(s).

Suitable O / W emulsions herein may comprise greater than 50% by weight of the composition as a continuous aqueous phase, with the remainder being a dispersed oil phase. The aqueous phase may comprise 1% to 99% water, based on the weight of the aqueous phase, along with any water-soluble and / or water-miscible ingredients. In these cases, the dispersed oil phase is typically present at less than 30% by weight of the composition (e.g., 1% to 20%, 2% to 15%, 3% to 12%, 4% to 10%, or even 5% to 8%) to help avoid some of the undesirable sensory effects of oily compositions. The oil phase may comprise one or more volatile and / or non-volatile oils (e.g., vegetable oils, silicone oils, and / or hydrocarbon oils).

[0052] Aqueous Carrier The composition preferably comprises an aqueous carrier. Preferably, the aqueous carrier is substantially water. Preferably, deionized water is used. Depending on the desired properties of the product, water from natural sources containing mineral cations can also be used.

[0062] If used, the present composition preferably contains from about 0.1% to about 10%, more preferably from about 0.2% to about 5%, by weight of the composition, of a whitening agent.

[0063] Ascorbic acid compounds are useful whitening agents, and ascorbyl glucoside is a preferred derivative of ascorbic acid compounds.

[0064] Conditioning Agent The compositions herein may comprise 0.1% to 50% by weight of a conditioning agent (e.g., 0.5% to 30%, 1% to 20%, or even 2% to 15% by weight). The addition of a conditioning agent can help provide the composition with desirable feel characteristics (e.g., a silky, smooth feel upon application). Some non-limiting examples of conditioning agents include hydrocarbon oils and waxes, silicones, fatty acid derivatives, cholesterol, cholesterol derivatives, diglycerides, triglycerides, vegetable oils, vegetable oil derivatives, acetoglyceride esters, alkyl esters, alkenyl esters, lanolin, wax esters, beeswax derivatives, sterols and phospholipids, salts, isomers, and derivatives thereof, and combinations thereof.

[0070] Other optional ingredients. The compositions herein may contain one or more optional ingredients known for use in topical cosmetic compositions, provided that the optional components do not unacceptably alter the desired benefits of the composition. In some cases, it may be desirable to select cosmetic active substances that function through different biological pathways so that the active substances do not interfere with each other. When the composition is in the form of an emulsion, the additional ingredients should not introduce instability (e.g., syneresis) into the emulsion. For example, it may be desirable to select optional ingredients that do not complex with other ingredients in the composition, particularly pH-sensitive ingredients such as vitamin B3 compounds, salicylates, and peptides.

[0071] Additional ingredients should be suitable for use in contact with human skin tissue without undue toxicity, incompatibility, instability, allergic response, etc. If present, optional ingredients may be included in an amount of about 0.001% to 50% by weight (e.g., 0.01% to 40%, 0.1% to 30%, 0.5% to 20%, or 1% to 10%) of the composition.

[0073] Method of using the cosmetic composition The method of use herein includes identifying a target area of skin on a human in need of treatment and applying the composition to the target area of skin during the treatment period. The target area of skin may be on the surface of the face, such as the forehead, perioral area, chin, periorbital area, nose, and / or cheeks, or on another part of the body (e.g., hands, arms, legs, back, chest). The human in need of treatment is one whose skin shows signs of oxidative stress, such as fine lines, wrinkles, hyperpigmentation, uneven skin tone, and / or other visible skin features typically associated with aging. In some cases, the target area of skin may not show visible signs of skin aging, but the user may still want to target such skin areas if they typically develop such problems as people age. In this way, the method can be used as a preventative measure to delay the onset of visible signs of skin aging.

[0074] The composition may be applied daily to the target area of skin, and to surrounding skin if desired, at least once daily, twice daily, or more frequently during the treatment period. If applied twice daily, there is an interval of at least 1 to 12 hours between the first and second applications. The composition is typically applied in the morning and / or at night before bedtime. The treatment period may last for at least one week (e.g., about two, four, eight, or even twelve weeks). In some cases, the treatment period will extend for several months (i.e., three to twelve months). In some cases, the composition may be applied at least once daily, or even twice daily, for the majority of days of the week (e.g., at least four, five, or six days per week) during a treatment period of at least two, four, eight, or twelve weeks.

[0075] The step of applying the composition can be performed by topical application. With respect to the application of the composition, the terms "topical," "topical," or "topically" mean that the composition is delivered to a target area (e.g., wrinkles or fine lines) while minimizing delivery to skin surfaces where treatment is not desired. The composition can be applied to a skin area and gently massaged in. The form of the composition or dermatologically acceptable carrier should be selected to facilitate topical application. While certain embodiments herein contemplate applying the composition to a region topically, it will be understood that the composition herein can be applied broadly to one or more skin surfaces. In certain embodiments, the composition herein can be used as part of a multi-step cosmetic regimen, in which case the composition can be applied before and / or after one or more other compositions.
