Description

Cosmetic composition comprising natural extracts as an effective component

The present invention relates to a cosmetic composition comprising a natural extract as an active ingredient.

The skin protects the body from various external stimuli and has a barrier function that blocks moisture from the inside. The epidermal layer of the skin develops into a thin stratum corneum while containing moisture through the process of differentiation. Structurally, the cells of the stratum corneum act like bricks, and the intercellular lipids of the keratinocytes act as mortar and constitute the skin barrier.

However, as the human body ages, dry skin tends to increase, and the need for a skin moisturizer is increasing due to air pollution and indoor heating. For this purpose, sugars and polyhydric alcohols have been used in cosmetics as general moisturizers as skin moisturizers. However, these moisturizers have a disadvantage in that stickiness occurs on the skin, and there is also a problem in that it does not provide sufficient moisturizing effect and continuous moisturizing effect to the skin. In addition, in summer when humidity is very high, the skin is sticky by drawing moisture from the outside, and in winter when the humidity of the external air is low, moisture is drawn from the skin and the skin becomes dry.

Moisture plays a role in transporting physiologically active substances necessary for the human body and helps the skin to remain soft and moist. However, its function can be easily lost due to excessive washing, lifestyle factors such as bathing, dry air, and environmental factors such as pollutants. There is an increasing trend in the number of people suffering from various disabilities.

Various cosmetic compositions have tried to improve the dryness of the skin by using various moisturizing agents such as sugars and polyols. For example, a natural moisturizing factor in the stratum corneum that inhibits moisture evaporating from the skin by strengthening the skin barrier function using ceramide, cholesterol, fatty acids, etc. (Natural moisturizing factor: NMF) amino acids, sodium pyrrolidone carboxylate, lactate, and hyaluronic acid with strong water-binding ability, sugar, polyol, etc. was intended to increase

Furthermore, in recent years, many cosmetics using natural products have been developed in order to reduce skin irritation caused by external chemical substances. Natural materials have fewer side effects on the skin, and as consumers' demand for cosmetics using natural materials increases, the value of development as a cosmetic raw material is further increasing.

In general, various raw materials are used in the process of making cosmetics, and 10 to 50 kinds of raw materials are usually used. These raw materials have been proven to be safe through skin irritation tests, but they can cause irritation, such as inflammation, itchiness, and allergies to the skin by being applied to the product. Skin irritations that may be caused by the use of cosmetics include irritation such as itching, stinging, and burning, and erythema and edema. Contact dermatitis may be roughly divided into irritant contact dermatitis, allergic contact dermatitis, sensory irritation and phototoxic dermatitis, but it is difficult to clearly distinguish them.

In order to solve these problems, a lot of cosmetics using natural products have recently been developed in order to reduce skin irritation caused by various chemical substances. Natural ingredients have relatively few side effects on the skin, and as consumers' response to cosmetics using natural ingredients increases, the value of development as a cosmetic raw material is increasing.
