C- Development of antioxidant black vitamin by using vitamin C-chitosan complex and its application into cosmetic ingredients for blue light protection

摘要

The present invention relates to an antioxidant carbon particle for cosmetics using a vitamin C-chitosan complex and a method for manufacturing the same, and more particularly, to an antioxidant carbon particle carbonized with vitamin C and a water-soluble amine compound, the carbon particle is 380 nm or less It has a function of absorbing more than 90% of light in the wavelength range of, and absorbing more than 50% of light in the wavelength range of more than 380 nm to 700 nm, and the carbon particles can maintain 90% or more of antioxidant activity for a long time of 2 years or more in atmospheric conditions. And, even after 30 days at moisture and 60℃, the antioxidant activity can be maintained at 50% or more, and at the same time, the antioxidant substances immobilized on the antioxidant carbon particles can continuously penetrate from the skin surface to the skin depth of 20 μm or more. It is easy to absorb blue light, which is widely emitted in everyday life such as smart device displays of computers and mobile phones, and LED lighting equipment, and can be continuously and stably absorbed by skin cells, so skin improvement effects can be expected in a short time. It relates to antioxidant carbon particles for cosmetics using vitamin C and a method for producing the same.
