Description

COSMETIC COMPOSITION INCLUDING OPUNTIA FICUS-INDICA STEM EXTRACTS AND AGAVE TEQUILANA LEAVES EXTRACTS}

The present application relates to a cosmetic composition, and more particularly, to a cosmetic composition for moisturizing the skin.

The skin is an organ that functions as a protective film that protects the living body from the external environment, and prevents loss of biological components in the human body, such as water and electrolytes, and at the same time prevents harmful substances from entering the human body.

The structure of the skin is largely divided into three layers: epidermis, dermis, and subcutaneous fat tissue in order from the outside. It is an institution.

In general, the moisture content of the skin is about 70% in the dermal layer, but decreases toward the epidermal layer, and becomes about 10 to 30% in the keratinocyte layer. The water supplied from the dermal layer moves to the top of the stratum corneum mainly by passive diffusion and is finally discharged to the outside. This is called Trans Epidermal Water Loss (TEWL), and it is known that the sebum component, which is a lipid film component of the keratinocyte layer, and epidermal lipids maintain this transepidermal water loss at an appropriate level.

On the other hand, various causes such as artificial temperature control of air conditioning/heating due to changes in the environment or lifestyle, frequent face washing due to makeup habits, skin stress due to various stresses and environmental pollution, and natural skin aging due to age increase As a result, the skin becomes dry, the surface becomes rough, and the skin loses its luster and looks dull, so the need for a skin moisturizer is increasing.

Natural materials not only have few side effects on the skin, but also the value of development as a raw material for cosmetics is increasing as consumers' response to cosmetics using natural materials has recently increased. Therefore, the demand for cosmetics using natural ingredients with fewer side effects and high consumer acceptance is gradually increasing.

In this application, the term "Bogum cactus ( Opuntia ficus-indica )" is a succulent plant of the cactus family and is a plant that grows naturally in Jeju Island and the southern coast. It is widely known as 'palm cactus' or 'baeknyeoncho'. Bogum cactus, which grows in a warm climate, contains abundant polysaccharides in its stem, which helps skin wound healing and supply of moisture.

In this application, the term "tequila agave ( Agave tequilana )" is a succulent plant of the genus Agave , and tequila is made by fermenting and distilling sap. It grows to about 10 m in height including the peduncle stem. The leaves that come out in the form of a rosette are more or less uniform in length, and there are dark brown spines of 1-2 cm at the tip of the leaves.

In this application, the term "extract" refers to an extract obtained by extracting the stem of the Bogum cactus, tequila agave leaf, or a mixture thereof, a diluted solution or concentrate of the extract, a dried product obtained by drying the extract, and the extract. It includes extracts of all formulations that can be formed using the extract itself and the extract, such as a refined product, a purified product, or a mixture thereof.
