Description

[0001] Moisturizing cosmetic composition [

The present invention relates to a cosmetic composition having a skin moisturizing effect. More specifically, the present invention relates to a cosmetic composition having a skin moisturizing effect, and more specifically to a cosmetic composition having a skin moisturizing effect, To a cosmetic composition for moisturizing the skin.

In the keratinocyte layer, a substance having a hydrophilic water retention capacity called a natural moisturizing factor (NMF) is present so that the skin functions to exhibit flexibility, and also to maintain proper moisture. However, when the water content of the stratum corneum is less than 10%, the skin becomes rough and the protective function of the body is lost and the aging phenomenon occurs. For example, in the case of dry skin, the aggregation force of keratinocyte is weakened, and a scaling phenomenon occurs in which keratinocytes are peeled off like scales from the skin surface. The reason why the skin is dried in this way is that the moisture content of keratinocyte layer is smaller than that of normal skin. In addition, changes in the environment or life patterns, various stresses and environmental pollution generated in social life, frequent cleansing due to make-up habits, and aging of the skin due to age increase are caused by the decrease of moisture in the stratum corneum, The surface becomes rough, the skin becomes lustrous and appears dull, and the problem of skin moisturization becomes more and more important.

Conventional moisturizers to properly maintain the moisture content of the stratum corneum of the skin include humectant or NMF components having moisture absorbing properties or natural water-soluble components containing these components, It serves as a place to stay. Examples of the humectant include polyols such as glycerin, sorbitol, propylene glycol, dipropylene glycol, and 1,3-butylene glycol. They exhibit excellent moisturizing power when applied to the skin, but they may give a sticky feeling or an unpleasant feeling due to inherent viscosity and physical properties of the polyol.

Another method is to increase the moisture retention in the stratum corneum by using an occlusive moisturizer to prevent water evaporation. As the closed moisturizer, there is a method of using a lipid component such as oil or wax. Moisture film is formed on the skin to suppress the evaporation of moisture, so that the moisturizing effect is maintained. However, the absorption effect is slow in the use feeling side, and the negative effect such as sticky shine is likely to occur at the same time.

 Also, NMF components such as sodium pyrrolidonecarboxylate (PCA-Na), sodium lactate, urea, or natural water-soluble components containing these components are difficult to maintain stability within the formulation due to their strong electrolytes , Raw materials extracted from natural materials have many problems such as insufficient effects, stability in formulations, side effects due to skin irritation, and the like, and studies for using natural extracts which are not harmful to the human body have been actively conducted.

On the other hand, bamboo bamboo (Bambusa Arundinacea) belongs to the bamboo family of perennial evergreen arboreous trees, which are hollowed with thick roots and branches. It is distributed in tropical India and most parts of Pakistan and is widespread in temperate and humid temperate regions, but flourishes to the maximum in frost-free conditions and grows up to 1000 meters in southern India.

Among the various types of bamboo, the fibers and pulp of prickly bamboo are mainly used to make paper products. The stem is mainly composed of cellulose, hemicellulose and lignan, and contains a small amount of resin. Bamboo is also used for cooking like bamboo shoots, but bamboo as a medicinal herb is particularly effective as a fever reducing agent. Recently, studies on the antioxidant and anticancer effects of bamboo salt have been actively conducted (Korean Patent Publication No. 10-20160035522), and the anticancer effect of bamboo powder itself has been reported (Japanese Patent No. 3497362).

Grape vine (grape vine) is a perennial deciduous broad-leaved tree with a vine and has the characteristics of a timber-like timber-like tree. In Korea, the name has been used since ancient times, and the grape name is known to originate from the original language of Central Asia, the origin of European species. Grape varieties are very diverse. Especially, about 10 genera and 500 species are distributed in the tropics. In Korea, there are 6 genera of 4 genera and most are trees with tendrils.

The vines form snow on every well-developed first-year branch, and the next year, new branches grow from the snow, and the new branches become fruit. It is a plant that grows well under adverse conditions, such as hot, dry climate and mountainous areas, in which most of the wilderness areas and sloping mountain areas bear fruit well due to the nature of the plants that endure the heat and the roots deeply into the ground. The fruit of the grapes is used to treat the stigma of the stigma caused by the paralysis of the root and vine.

Under these circumstances, the inventors of the present invention have found that when a component having a skin moisturizing effect is searched, the mixture of the water-soluble bamboo sap and the saponification of the vine saplings exhibits a superior skin moisturizing effect because of its high water holding ability and water retention ability.
