Description

Skin moisturizing multi-balm cosmetic composition [0001]

The present invention relates to a multi-night cosmetic composition which can improve moisturizing and dryness of the skin, and more particularly, to a multi-night cosmetic composition which can improve skin moisturization and dryness, Acetate. &Lt; / RTI >

In general, the skin plays a very important role as a barrier function to protect an object from the outside. Barrier function means protection against external stimuli (chemicals, air pollutants, dry environment, ultraviolet ray, etc.) and protection against excessive divergence of body water through the skin. This protective function is called keratinocyte The function can be maintained only when the configured stratum corneum is normally formed.

The skin is largely divided into three layers of epidermis, dermis and subcutaneous adipose tissue in order from the outside, and functions to protect the human body from physical or chemical stimulation from the external environment. In particular, the skin carries about 65 ~ 70% of the moisture of the human body, that is, the physiologically active substance necessary for the human body, and helps the skin to maintain the smooth and moist condition. . In addition, the epidermis is divided into stratum corneum, granular layer, pore layer, and basal layer. The cells of the stratum corneum act like bricks, and interstitial lipids between keratinocytes function as mortar to form skin barrier J. Invest. Dermatol 80 (Suppl.), 44-49, 1983). The stratum corneum of the epidermis contains about 10 to 20% of water and is present at the outermost part of the human body, thereby suppressing evaporation of water from the outside of the body, while blocking excessive material penetration from the outside. These stratum corneum surfaces are wrapped in a thin natural protective film made of sebum from the sebaceous glands and perspiration from the sweat glands to prevent water evaporation. This can be thought of as a sponge (horny layer) faded with water wrapped in a plastic wrap (a natural protective film) that does not allow water to pass through. The cells that make up this stratum corneum have a high concentration of Natural Moisturizing Factor (NMF), which is a water-soluble ingredient, to help skin maintain flexibility and maintain proper moisture. For example, The material is not only water-soluble, but also effectively binds to moisture and inhibits the drying of water from the skin (J. Invest. Dermatol. 54, 24-31, 1970). However, due to changes in the environment or changes in lifestyle, there is an artificial temperature regulation of cold / heating, skin stress caused by various stresses and environmental pollution in social life, frequent washing according to make-up habit, The moisture of the stratum corneum is reduced due to various causes of the skin, and the skin becomes dry, the surface becomes rough, and the skin appears to be dull and dull. Therefore, the need for a skin moisturizer is increasing.

Conventionally, a method of increasing moisture retention in the stratum corneum by using humectant or occlusive moisturizer to prevent water evaporation as a humectant is most widely used to be. Most of the hummocktites are polyols such as glycerin, propylene glycol, 1,3-butylene glycol, and polyethylene glycol. However, they are disadvantageous in that they have a high stickiness due to the inherent viscosity and physical properties of the polyol when applied to the skin. In addition, lipid components such as ceramides and essential fatty acids and lipid complexes have been used as closed moisturizers (J. Invest. Dermatol. (5), 731-740, 1994), but the structure of emulsified interfacial membranes is disturbed in emulsified formulations, And there is a disadvantage in producing a transparent gel-like product. Formulations containing the lamellar liquid crystals, which have been under much research until recently, are known to have good moisture retention due to their similarity to the skin horny structure, but they are only available in a specific composition of the raw materials and thus have a problem in universal use.

Accordingly, recently, cosmetics having 100% raw materials derived from plant-derived natural materials are being developed while eliminating chemical substances. Typical examples include aloe butter, cocoa butter (Cocoa butter) Butter, Shea Butter, Pistachio Butter, Avocado Butter, Mango Butter, Soy Butter, Almond Butter, Olive Butter, ), Wheat Germ Butter, Cupuacu Butter, Jojoba Butter, Macadamia Seed Butter, Apricot Butter, Grape Seed Butter, Hemp Butter, Illipi Butter, Kokum Butter, Sal Butter, and the like are known.

In particular, the above-mentioned shea butter is a vegetable oil collected from the fruit of a Karite tree and has recently been attracting attention as a skin moisturizing agent and a softening agent since it has no mutual rejection reaction with human skin.

Jeju citrus essential oil is essential oil of Jeju citrus peel. Citrus essential oil is a fragrant substance contained in citrus peel. It can obtain only a very small amount when extracting, and studies are being conducted to obtain such citrus essential oil component more efficiently.

In addition, d-limonene, one of the main components of citrus essential oil, is a substance having various physiological activities without harmful effects on the human body and the environment. It is an essential oil extracted from citrus fruits including citrus fruits In the developed countries, it is used as a cleaning agent. In addition, it is known that the essential oil component of the citrus family has insecticidal and antimicrobial properties, and it is reported that it exhibits antibacterial activity against various fungal pathogens such as Aspergillus fungi have.

Various studies using orange extract and d-limonene contained therein have been carried out. For example, a deodorant composition [Korean Laid-open Patent No. 1990-1384], a detergent composition [Korean Published Patent Application No. 1995-29341 / 1999 -14389], a repellent composition [Korean Patent Laid-Open Publication No. 2002-92774], a preservative preparation method using a citrus extract, and a method for producing a processed food [Korean Patent Publication No. 1996-0000092].

Tocopheryl acetate, also known as vitamin E acetate, is derived from natural tocopherol and is a lipid-soluble substance obtained by acetylating tocopherol and acetic acid. It serves to prevent oxidation of these constituents in the phospholipid adjacent to unsaturated fatty acids .

Tocopheryl acetate inhibits the oxidation of the outer surface of the skin when used with vitamin C and antioxidant functions that can delay or prevent skin damage and inhibits oxidation of the inside of the skin. Therefore, synergy is great, and the outer surface of the skin is damaged When the water is not maintained normally, tocopheryl acetate restores the function of the cell and heals the stimulation. Therefore, it balances the skin layer and blocks the evaporation of moisture. It has a moisturizing effect. Oxidation occurs when it is combined, and tocopheryl acetate acts as an antioxidant to increase the shelf life of cosmetics.
