Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic composition for protecting skin against infrared rays containing Hibiscus extract as an active ingredient,

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

The skin has the primary function and the beauty function to protect our body from the external environment. The purpose of cosmetics is to protect the skin from the harmful environment and the aesthetic function which cleanse or beautifully express human skin. The role of skin declines due to various harmful environments (ultraviolet rays, increase of irradiation dose, air pollution, stress, etc.). Cosmetics are used for various kinds of skin caused by reactive oxygen, free radicals and peroxides, It improves the problem, protects the skin and helps the skin maintain normal function.

Skin aging can be divided into endogenous aging and photoaging. Endogenous aging refers to the inevitable aging phenomenon as the years pass, and photoaging is the aging phenomenon observed in long-exposed faces, hands, and behind the neck due to environmental factors such as sunlight, cold, wind, It says. The photoaging phenomenon is deeply related to intrinsic aging, such as rough wrinkles, pigmentation, loss of skin elasticity, and skin cancer, but exposure to ultraviolet light can be avoided. Recently, when the temperature of the skin increases due to the external rays such as ultraviolet rays and infrared rays, various enzymes in the skin are affected, and thus, symptoms such as skin redness, skin dryness, In order to maintain health, it is necessary to eliminate these external and internal factors.

The Korean Patent Registration No. 10-784238 discloses a cosmetic composition for skin-cooling, wherein the sprayed contents form a gel to cool the skin by slowing the vaporization rate of the cooling gas. In the skin application of Korean Patent Application No. 10-2010-84165 Cooling compositions cause phase change when experiencing transient systemic fever, high fever, exposure to a very warm environment, physical exercise, or the like, resulting in a cooling or cold feeling of the skin.

However, there is no known technique for controlling skin temperature using Hibiscus extract.

Accordingly, the inventors of the present invention have found that a hibiscus extract is suitable as a natural material capable of controlling such phenomenon in order to improve the skin temperature due to the rise of the skin temperature by ultraviolet rays, infrared rays, etc., It was found that the effect of preventing skin aging due to heat by decreasing the temperature of the skin when applied actually completed the present invention.

Accordingly, the object of the present invention as described above is achieved by a cosmetic composition for skin temperature control comprising a hibiscus extract as an active ingredient

Preferably, the Hibiscus extract is contained in an amount of 0.00001 to 20.0% by weight based on the total weight of the cosmetic composition.

Preferably, the cosmetic composition is a solution, suspension, emulsion, paste, gel, cream, lotion, powder, soap, cleansing oil, powder foundation, emulsion foundation, wax foundation, pack, massage cream and spray Lt; RTI ID = 0.0 > of: < / RTI >

The present invention relates to a cosmetic composition for controlling skin temperature, comprising a hibiscus extract as an active ingredient. The hibiscus extract has a characteristic of controlling skin temperature which can be generated by ultraviolet rays, infrared rays, and the like, and has an effect of preventing heat aging.

In addition, by applying the cosmetic composition containing the hibiscus extract to the skin, the skin temperature is lowered to prevent skin aging caused by heat.

The Hibiscus Sabdariffa extract used as an active ingredient in the cosmetic composition of the present invention is used for imparting a function of restricting the temperature rise of the skin, which may be caused by ultraviolet rays and infrared rays, to suppress the skin aging phenomenon caused by heat.

The Hibiscus of the present invention is a generic term for plants belonging to the genus Euphorbiaceae and the Acanthopanax senticosus, and is also called Hawaiian Hibiscus, Chinese Rose, Chinese-Hibiscus, Shoe-flower and Blacking Plant. In horticulture, it refers to Hus rosa-sinensis and various hybrids made here. Leaves are alternate phyllotaxis, 9cm long, with petiole, broad ovate, pointed end, irregular sawtooth. The leaf surface is glossy and dark green. Flowers are wide funnel type, one on each side of upper part of new branch and there are small flower branches. Calyxes are like tubules and the ends are divided into 5 pieces. The petals are red and 5, and the surgery is combined like a barrel, with many anthers at the end. The pistil is longer than the surgery and the tip is divided into 5 pieces. Flowers bloom from summer to autumn, but blooms throughout the year when the proper temperature is maintained. In winter, flowering stops due to low temperature. It grows well at 16 ~ 30 ℃, it is wintering above 5 ℃ and likes rays. More than 3,000 species have been developed in the state of Hawaii and have been made into state flowers. The color of the flower is white, red, magenta, red, orange, yellow etc. There are also double flower, flower diameter is 10 ~ 25cm.

Since the hibiscus contains a human body effective physiologically active substance, the excretion of waste products is rapidly excreted in the case of drinking, and the effect is excellent for atherosclerosis, anti-cancer component, enteritis, bronchitis and the like. In addition, pyruvic acid in Hibiscus saab legworm extract is known to have a weight loss effect as well as a protein dissolving effect when digested with DHA (dihydroxyacetone).

Manufacturing example  One : hibiscus  Preparation of extract

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

Experimental Example  One : hibiscus  Protecting skin cells from heat by extract

Human normal fibroblast cells were inoculated into a 24-well plate at a concentration of 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. Then, hibiscus extracts were treated with 0.5% and 1.0% (v / v), respectively, 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: skin temperature control effect

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

Twenty healthy subjects in their 20s and 40s were sedated for about 20 minutes in a thermostat and a thermostat, and their thermal and facial temperatures were measured 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, the nutritional cream prepared in Example 1 containing the hibiscus extract and the nutrient cream of Comparative Example 1 not containing the hibiscus extract on the other side were applied, and the facial thermal and facial temperature was measured. The skin temperature The degree of change was evaluated and the results are shown in Table 8

Skin temperature change (℃) sample Comparative Example 1 Example 1 Before use 30.43 + - 1.12 30.67 ± 1.10 After infrared irradiation 34.68 ± 0.56 34.63 + - 0.50 after use 33.86 ± 0.59 32.74 + - 0.56

As shown in Table 8, in Example 1, which is a cosmetic containing hibiscus extract, the skin temperature reduction effect was superior to Comparative Example 1 which did not contain hibiscus extract.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the same is by way of illustration and example only and is not to be construed as limiting the scope of the present invention. It is therefore intended that the scope of the invention be defined by the claims appended hereto and their equivalents.
