Composite powder for simultaneously blocking infrared and ultraviolet rays and cosmetics composition using the same

Abstract

Disclosed is composite powder comprising infrared-ray blocking particles; and ultraviolet-ray blocking particles coated onto one surface of each of the infrared-ray blocking particles, and cosmetics composition using the same, wherein the composite powder using both the infrared-ray blocking particle and the ultraviolet-ray blocking particle enables to simultaneously block the infrared and ultraviolet rays. Thus, if the composite powder of the present invention is applied to the cosmetics, it is possible to minimize the rough wrinkles, irregular pigmentary deposits, loss of skin elasticity, disturbance of skin barrier function, skin damages such as cancer of the skin, and skin aging, and also to boost SPF (Sun Protection Factor) and PA (Protection Factor of UVA) of the related art sunscreen. Especially, the present invention uses the composite powder prepared by coating one surface of the infrared-ray blocking particle with the ultraviolet-ray blocking particles, instead of mixing powder prepared by simply mixing the infrared-ray blocking particle and the ultraviolet-ray blocking particle. That is, since the small-sized ultraviolet-ray blocking particles are coated onto and stably fixed into the surface of the infrared-ray blocking particle, it is possible to prevent aggregation of the ultraviolet-ray blocking particles, thereby preventing deterioration in uniformity of adhesion to the skin, and deterioration of the ultraviolet-ray blocking efficiency.
