Description

{COSMETIC COMPOSITION HAVING THERMAL EFFECTS}

In this specification, a thermal cosmetic composition is disclosed.

When the cosmetic composition is applied to the skin, an increase in the temperature of the skin accelerates the movement of the active particles in the composition to increase the penetration rate of the skin, as well as increase the solubility in the composition, thereby further increasing the concentration difference of the active ingredient between the composition and the skin Thereby further accelerating the skin absorption rate of the active ingredient. In addition, as the temperature rises after application of the skin, the blood flow velocity in the body becomes faster and the blood vessel expands, thereby increasing the rate of blood flow through the blood vessel, thereby activating the circulation of the body. And the discharge is further increased.

Conventionally, a massage formulation containing glycerin is a formulation widely used because it imparts a thermal sensation. Hydration heat is generated by the reaction of these components with a high content of glycerin and water. However, the prior art is very limited to glycerin among many polyol raw materials, and there is a disadvantage that a sufficient thermal sensation can not be obtained in the case of water- . Conventionally, the method of raising the temperature when the cosmetic composition is applied to the skin by increasing the content of glycerin conventionally has a limitation in terms of proper blending with other active ingredients by increasing the content of glycerin. Even if the content of glycerin is increased, Persistence and marginality problems. Further, when a polyol is used, there is a problem that it is necessary to apply friction to the skin after applying it to the skin with a steady massage or the like, resulting in a slight heat effect.

As described above, the conventional warm and warm cosmetic composition has insufficient heat and long-lasting effect and is insufficient to provide a sufficient and continuous feeling of warmth to the skin, and thus it is insufficient to remove waste materials such as fine dust, sebum and keratin. Further, in the case of a formulation containing a polyol, there is a disadvantage that the feeling of use is sticky.
