Description

(Cosmetic Composition Containing Cholesteric Liquid Crystal With Dual Capsule Process)

The present invention relates to a cosmetic composition containing a cholesteric liquid crystal by a double capsule process, and more particularly to a cosmetic composition for moisturizing containing a cholesteric liquid crystal by a double capsule process.

About 65-75% of the human body consists of water. Moisture acts as a carrier of various physiologically active substances required for the human body and allows the skin to maintain a smooth and moist condition. The stratum corneum of the epidermis contains 10 ~ 20% of water and it prevents the water from evaporating, and prevents the penetration of excess moisture from the outside.

The basic goal of using cosmetics is to keep the skin clean and moisturize the skin through moisturizing, thereby inhibiting skin drying, which is the most important factor of skin aging and wrinkle formation. Moisturizing function, which is the most important factor of skin aging, is caused by the drying of the horny layer of the skin, which accelerates the keratinization phenomenon, which roughens the surface of the skin, irregularity of the skin texture, wrinkles and the elasticity of the skin are remarkably decreased.

Therefore, how to keep skin moist and smooth is the most important factor in preventing skin aging.

There are two states of existence associated with moisture retention in the stratum corneum: NMF in keratinocytes, keratin and water contained in lamellar liquid crystal structure of keratinocytes. Although the relationship between the two is not yet clearly distinguished, it is presumed that they are responsible for the water retention capacity of the stratum corneum.

First, the relation between NMF and keratins in keratinocytes is known that NMF interacts with keratin to interact with water molecules to reduce intermolecular forces between molecules of keratin fibers to give flexibility to each layer. The keratinocyte intercellular quality is known to form a lamellar liquid crystal structure with water and to function as a barrier by preventing water evaporation from the body.

More specifically, the stratum corneum, which plays an important barrier function, is structured by Keratinocyte as a dead cell in the process of keratinization, accumulating in the water layer, and intercellular quality being buried therebetween.

The subject of intercellular quality is ceramide, which accounts for about 50% of the intercellular quality, and cholesterol and free fatty acids. Ceramide is divided into several types depending on the difference in the number of carbon atoms and unsaturation of fatty acids bound to sphingoid bases and binding to fatty acids depending on the amide bond with sphingosine or phytosphingosine as a basic structure. In addition, ceramide is derived from lamella granule formed in the cell membrane in the keratinization process of keratinocytes, and is secreted out of the cell just before it is transformed from granule cell to keratinocyte, and rearranged between keratinocytes to form a unique liquid crystal structure. And performs a barrier function according to the liquid crystal structure and at the same time holds a certain amount of moisture in accordance with hydrogen bonding in the structure, thereby retaining moisture of the stratum corneum.

In addition, there is a natural moisturizing factor (NMF) in the keratinocyte which has both hygroscopicity for supplying water and moisturizing property for maintaining it. NMF is a protein composed mainly of keratohyalin which is present in the granular layer and is composed of amino acid, pyrrolidonecarboxylic acid (PCA), lactic acid and so on. .

In addition, various glycosaminoglycans such as hyaluronic acid, chondroitin sulfate, and collagen, various amino acids, and saccharides such as hyaluronic acid and chondroitin sulfate present in the epidermis layer and the dermal layer are combined to maintain skin homeostasis and to maintain moisturization of the skin, Complementary action.

Moisture content of the epidermis is relatively constant, ranging from 65% to 70% from the basal layer to the granular layer, but decreases to 40% at the granular layer and the stratum corneum boundary layer and decreases to 15% at the top of the stratum corneum.

 This is a phenomenon caused by passive diffusion from the inside to the outside of the body, and the transdermal water loss is 0.1 to 0.4 mg / cm 2 per hour in normal healthy skin. This loss of moisture from healthy skin is a normal mechanism of action for healthy skin and it is natural for skin protection to function as skin protection, due to seasonal changes, body parts and characteristics, and natural changes in skin moisture control.

However, contemporary people's skin is not able to perform the original skin function due to various harmful environments encountered by modern people and sudden changes in the skin environment, which is difficult for the skin to adapt naturally, and also exhibits an adverse reaction, .

In particular, the most prominent skin problem among these symptoms is skin dryness, which is the first cause of various diseases such as skin aging, pruritus and atopy.

Various studies have been conducted on components having a skin moisturizing effect. Recently, researches on cosmetic compositions containing cholesteric liquid crystals have been actively conducted.

Korean Patent Laid-Open Publication No. 2014-0147505 discloses a cholesteric liquid crystal composition comprising three compositions of cholesteryl isostearate, cholesteryl nonanoate, and cholesteryl chloride. Korean Patent Laid-Open Publication No. 2017-0138930 discloses a cosmetic composition comprising cholesteric liquid crystal particles having an average particle diameter of 0.1 탆 to 500 탆.

In the present invention, the intercellular quality of the stratum corneum is affected by the drying of the external environment or the degradation of its content as the age increases, resulting in a change in the lamellar liquid crystal structure, To overcome this problem, we developed a cholesteric liquid crystal by using a double capsule process and applied it to cosmetics, so that strong moisturizing effect was maintained for a long time to enhance barrier function of skin and enhance skin moisturization.

The present invention relates to a moisturizing cosmetic composition containing a double encapsulated cholesteric liquid crystal.

Preferably, the dual encapsulation is to encapsulate the cholesteric liquid crystal with a solution comprising sodium hyaluronate.

Preferably, the double encapsulation is to encapsulate the cholesteric liquid crystal with a solution comprising sodium hyaluronate, 1,2-hexanediol, 1,3-propanediol, ethylhexyl glycerin and agar.

Unless defined otherwise, all technical terms used in the present invention have the following definitions and are consistent with the meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. In addition, preferred methods or samples are described in this specification, but similar or equivalent ones are also included in the scope of the present invention.

Liquid crystal means a state of a material that simultaneously exhibits the peculiar fluidity of a liquid and the optical anisotropy peculiar to crystals. When the liquid crystal is broadly classified, it can be classified into a smectic liquid crystal, a nematic liquid crystal and a cholesteric liquid crystal.

A cholesteric liquid crystal (CLC) is a layered spiral structure of molecules, so that the interval between layers changes with temperature. Since the pitch interval in which the direction of the molecular axis rotates 360 degrees as a whole is close to the wavelength of visible light, when white light is projected there, scattering light is generated in the pitch interval according to Newton's circular pattern principle, and color is changed. Therefore, when a cholesteric liquid crystal is used, a visually differentiated cosmetic material can be obtained. In the present invention, the cholesteric liquid crystal may be at least one selected from the group consisting of cholesterol, cholesterol derivatives and polymer derived from animal or plant origin.

 The cholesterol derivative includes all cholesterol derivatives that can be used in the art, and specifically refers to a compound obtained by halogenating or esterifying the hydroxyl group at the terminal portion of the cholesterol molecule. For example, there may be mentioned cholesteryl isostearate, cholesteryl nonanoate, cholesteryl propionate, cholesterol lanolate, cholesterol oleyl carbonate, cholesteryl nanoate, cholesteryl chloride, cholesterol, But are not limited to, lactose, rostanol, campesterol, stigmasterol, sitosterol, ergosterol, cerevistrol, chimosterol, dihydrocholesterol, cervolosterol, lanosterol, dihydrolanosterol, aginosterol, gihydroagannosterol and phytosterol And may be at least one selected from the group consisting of

The present invention relates to a moisturizing cosmetic composition containing a double encapsulated cholesteric liquid crystal. Specifically, the present invention provides a cholesteric liquid crystal by a double capsule process as if the intercellular stratum of the stratum corneum form a lamellar liquid crystal structure together with water to prevent moisture evaporation from the body to function as a barrier to maximize the skin moisturizing effect The cholesteric liquid crystal of the present invention complements the function of the intercellular lobe functioning as the content of the cells decreases with age, thereby improving skin dryness due to the external dry environment and aging, so that a strong moisturizing effect is maintained for a long time. The present invention relates to a cosmetic composition containing a steric liquid crystal.

As used herein, the term "dual encapsulation" means performing a further coating of a cholesteric liquid crystal with a liquid comprising a hyaluronic acid component. Specifically, the additional coating means that the cholesterol liquid crystal is encapsulated in a solution containing hyaluronic acid or a hyaluronic acid derivative, for example, a coating solution containing sodium hyaluronate, more preferably sodium hyaluronate, ≪ / RTI > hexanediol, 1,3-propanediol, ethylhexyl glycerin and agar.

The double encapsulated cholesteric liquid crystal can include the coating solution and the cholesteric liquid crystal in a mixing weight ratio of 8: 2 to 4: 6, preferably 6: 4. When the mixing weight ratio is out of the above range, double encapsulation may not occur efficiently or the feeling of use may become poor.

The double encapsulated cholesteric liquid crystals preferably have a diameter of 4.0 to 5.0 mm.

The cosmetic composition of the present invention is obtained by blending a cholesteric liquid crystal using a double capsule process. The amount of the cosmetic composition is 0.1 to 50.0% by weight, preferably 1.0 to 10.0% by weight, based on the total weight of the cosmetic composition.
