Description

TECHNICAL FIELD [0001] The present invention relates to a cosmetic composition having excellent skin cooling and moisturizing effect,

The present invention relates to a cosmetic composition excellent in skin cooling and moisturizing effect. More specifically, the present invention relates to a cosmetic composition having excellent formulation stability and lowering the temperature of the skin when applied to skin, thereby providing skin cooling and moisturizing effect.

The main function of human skin is to block external pollutants such as ultraviolet ray blocking, microorganisms, chemicals, and temperature control in the body. The skin is composed of epidermis, dermis and subcutaneous fat layer in turn from the surface, and it is composed of pores and sweat glands.

The epidermis consists of the stratum corneum, the granular layer, the superficial layer and the basal layer, and the stratum corneum constitutes a skin barrier to block external substances and to maintain moisture of the dermis layer. The skin layer is about 10 ~ 20 ㎛ thick, and the pods filled with protein are embedded in the nonpolar layered lipid between cells. Cholesterol (30%), free fatty acids (15%) and ceramides (50%) are the main components of the lipid layer which is the core of skin barrier. The main components of the lipid layer are derived from lamellar bodies of the granular layer.

Men's and women's skin is different from skin structure and function by hormones secreted during puberty. Generally, the thickness of the dermis is larger than that of the females, but the thickness of the epidermis and fissure is small. The total amount of lipids constituting the skin barrier is not different according to the sex, but when the age is the same, the composition ratio of ceramide is higher in male skin. The amount of sebum is much higher in males than in females and in relatively sweaty men, the average pH of the skin is 4.6, which is lower than that of females.

There is an organ that secretes sebum, called sebum line, in the pore. Here, the pores are secreted into the hair follicles, and when the sebum is discharged from the body through sweat, the pores become large. When the pores become wider, the skin becomes dry and elastic.

The correlation between skin temperature and sebum and pores has been revealed through several articles, and it is generally reported that when the skin temperature becomes higher, it becomes more dry and the pores become wider. In addition, blackheads and acne are known to correlate with skin temperature.

Therefore, the use of cosmetics with a cooling effect that lowers the skin's temperature helps skin moisturize, pore shrinkage, blackheads, and acne, helping to make trouble-free skin.

Meanwhile, guaiazulene (1,4-dimethyl-7-isopropylazulene) is extracted from chamomile and guaiacum. Specific examples include chamomile essential oil (Guaiac wood oil), Callis Intratropica Blue , and Chamomile ( Matricaria chamomilla L. ). It is a skin-soothing ingredient that strengthens the skin barrier and helps prevent and repair damage to the skin. It is widely used in cosmetics and pharmaceuticals because it excellently cleanses reddened skin after dermatology. Guaiazulene is a component having a polar nature in molecular structure and a dipole moment, as compared with nonpolar naphthalene having a similar structure. Due to this unusual structure, it absorbs visible light at 600nm and has a blue color. However, although the guaiazulene has a unique color as a coloring agent, it is extremely unstable against light and heat, so that the stability of the formulation is low, and discoloration occurs.

Prior art related to the present invention is disclosed in Korean Patent Registration No. 10-0832333 (published on May 26, 2008, entitled "Composition for improving skin wrinkles containing guanamide compound as an active ingredient").

It is an object of the present invention to provide a cosmetic composition which is excellent in skin cooling, size reduction of pores and moisturizing effect.

Another object of the present invention is to provide a cosmetic composition which is excellent in esthetics such as color of a formulation in the production of a cosmetic composition.

Yet another object of the present invention is to provide a cosmetic composition which is free from skin irritation and which is excellent in a soothing effect on the skin.

Still another object of the present invention is to provide a cosmetic composition which is excellent in formulation stability of a cosmetic composition such as separation of cosmetic formulations and prevention of discoloration.

One aspect of the present invention relates to a cosmetic composition excellent in skin cooling and moisturizing effect. In one embodiment, the cosmetic composition having excellent skin cooling and moisturizing effect contains erythritol, guaiazulene and sodium benzotriazolyl butyl phenol sulfonate as active ingredients, The guaiazulene and sodium benzotriazolylbutylphenol sulfonate are included in a weight ratio of 1: 1 to 1: 3.

In one embodiment, 0.05 to 10% by weight of erythritol, 0.01 to 5% by weight of guaiazulene and 0.01 to 8% by weight of sodium benzotriazolylbutylphenol sulfonate may be included in the total weight of the cosmetic composition.

In one embodiment, the cosmetic composition may be a solution, suspension, emulsion, paste, gel, cream, lotion, powder, soap, surfactant-containing cleansing, oil, powder foundation, emulsion foundation, wax foundation, have.

Experimental Example  3: Skin temperature  Reduction evaluation

Among the above-mentioned examples and comparative cosmetic compositions, the skin temperature reduction effect was evaluated for example 4 as a representative. The skin temperature was measured with an infrared ray irradiator using a thermal imaging camera T-420 before and after the warming of the face, and the entire face after the application of the Example 4 was photographed. In the photographs taken, the temperatures of the test site and the unused site were analyzed and the results are shown in Tables 4, 4 and 5. On the other hand, the measured skin temperature unit is ° C.
