Description

TECHNICAL FIELD [0001] The present invention relates to a cosmetic composition for skin temperature control,

The present invention relates to a cosmetic composition for regulating skin temperature, which contains a herb extract which is characterized by controlling skin temperature rising by an external environment such as infrared rays and suppressing skin aging and skin troubles caused by heat.

Skin is the primary protective membrane of the human body, which protects the internal organs of the body from changes in temperature and humidity and from external stimuli such as pollutants, and plays an important role in the maintenance of body homeostasis, such as body temperature control. As with other organs in the human body, such skin is gradually aged as a person ages, and skin elasticity loss, keratinization, wrinkle formation, spots and freckles increase, and cosmetics are caused by these harmful factors It improves various skin troubles caused by highly reactive reactive oxygen, free radicals and peroxides, as well as protects the skin and helps the skin to maintain its normal function.

Skin aging can be divided into endogenous aging and photo aging. The endogenous aging refers to the inevitable aging phenomenon as the years pass. The photo aging is caused by environmental factors such as sunlight, cold, wind, etc., and aging phenomena observed on the skin such as face, . The photoaging phenomenon is deeply related to intrinsic aging, such as coarse wrinkles, pigmentation, skin elasticity loss, and skin cancer, but exposure to ultraviolet light can be avoided.

When the temperature of the skin rises due to the temperature change due to carbon dioxide greenhouse gas emissions and ozone increase, so called skin warming, the collagen decreases and the dermal layer is damaged. As a result, the skin becomes dull and the elasticity of the skin decreases, . As the skin temperature rises, the natural defense substrate increases the heat receptor in the skin cells, and the generated heat makes the skin in the skin dry except the blood components. This makes nutrient delivery to the skin difficult and accelerates skin dryness and promotes aging. Therefore, it is necessary to remove these external and internal factors in order to keep the skin healthy.

Korean Patent Laid-Open No. 10-2014-0106185 relates to a pharmaceutical composition for preventing skin aging and a cosmetic composition containing an extract of Aspergillus as an active ingredient.

Conventionally, Korean Patent Registration No. 10-784238 discloses a composition for controlling skin heat by applying the composition to a skin. In Korean Patent Registration No. 10-784238, a cosmetic composition for skin cooling which cools skin by forming a gel and slowing the rate of vaporization of a cooling gas And Korean Patent Laid-Open No. 10-2010-84165 discloses a skin that causes a phase change when experiencing transient full body heat, high temperature, exposure to a very warm environment, physical exercise, etc., A cooling composition for application is proposed.

Accordingly, the inventors of the present invention found that a herb extract is suitable as a natural material that can control such phenomenon in order to improve the skin temperature due to the increase of the skin temperature by infrared rays and the like, It has been confirmed that the skin temperature is actually lowered to prevent skin aging caused by heat, and the present invention has been completed.

Accordingly, the object of the present invention as described above is attained by a cosmetic composition for controlling skin temperature comprising an extract of Aspergillus as an active ingredient

Preferably, the herb extract is contained in an amount of 0.01 to 20.0% by weight based on the total weight of the cosmetic composition.

Lithospermum erythrorhizon of the present invention belongs to Boraginaceae and is also called sukcho, 芝 草 or 紫 丹. As shown in the erythrorhizon, the erythro-red color indicates the red color, and the lysosine root means the red color and the cow's root. Pruning is conical, branched, 7 ~ 14cm in length and 1 ~ 2cm in diameter. The surface is rough and wrinkled with red color. The epidermis is easy to fall off, but the vagina is hard and easy to break. It is harvested in spring and autumn, dried in the sun, and grown or cultivated in sunny areas of our alpine region.

It is a medicinal medicine commonly used to cool the blood inside the body, to help the blood circulation and to treat the margins. It has a lot of blood in the blood, it is poisonous, and the margin does not grow well and becomes worse. The spot is purple or black, It is applied to symptoms. In the <Korean Primary Book Illustrated>, "the endowment is the root of the periwinkle of the dentistry. The taste is sweet and the quality is cold. It is effective when blood circulation, hematochezia, and antiepileptic effects are seen, and the hemorrhagic reaction appears to be tingling. It also has a rapid effect on hematemesis, nosebleed, and urine bleeding. "

It is to be understood by those skilled in the art that these embodiments are only for describing the present invention in more detail and that the scope of the present invention is not limited by these embodiments in accordance with the gist of the present invention .

Production Example 1: Preparation of a seedling extract

1 kg of dried shoots (root portion) was precipitated in an aqueous solution mixed with ethyl alcohol and water 7: 3 (v / v) for 5 days, filtered through 300 mesh, and then concentrated at 80 ° C using a vacuum decompression concentrator . The herb extract thus obtained was again dissolved in 1,3-butylene glycol so as to be easily applicable to the product.

EXPERIMENTAL EXAMPLE 1: Protective Effect of Herb Extract on Heat-induced Skin Cells

Human normal fibroblast cells were inoculated in a 24-well plate at 1 × 10 ⁵ cells / well and cultured for 24 hours. After culturing, the culture medium was discarded, and the cell viability was measured after thermally stimulating the cells using an infrared ray irradiator. Thereafter, each of the wells was treated with 0.5% and 1.0% (v / v) of extracts for 3 days, and cell viability in each well was confirmed by MTT assay. The results are shown in Table 1 below .

Experimental Example 2: Effect of controlling skin temperature

In order to examine the skin temperature control effect of the cosmetic composition containing the herb extract of the present invention, the following experiment was conducted.

Twenty-one healthy subjects in their 20s and 40s were sedated for about 20 minutes in a thermostatic chamber and then examined for facial thermal and facial temperature using an infrared thermometer (IRIS-XP / MEDICORE, korea). After 10 minutes of near infrared irradiation, the surface temperature and the surface temperature of the skin were measured. Immediately on the right side of the face, the cream prepared in Example 1 containing the herb extract and the cream of Comparative Example 1 not containing the herb extracts were applied to the other side, and the facial thermal image and the facial temperature were measured. The results are shown in Table 3. &lt; tb &gt; &lt; TABLE &gt;
