Description

Cosmetic composition containing a high content of pure vitamin C {COSMETIC COMPOSITION COMPRISING HIGH CONCENTRATION OF PURE VITAMIN C}

The present invention relates to a cosmetic composition capable of maintaining a stable state while containing a high content of pure vitamin C.

Cosmetics are products that clean and beautify the human body, and as the economy develops and consumption levels increase, interest in cosmetics is increasing, and various raw materials are used as cosmetic compositions. In recent years, there has been an increasing demand for cosmetic compositions having various functions such as antioxidant, immune function enhancement, collagen production, and the like, beyond basic functions such as conventional moisturizing and whitening effects.

Among the raw materials constituting the cosmetic composition, pure vitamin C is known to perform various functions, such as an immune strengthening function and a function of promoting collagen production, in addition to performing a function of protecting the skin damage caused by ultraviolet rays by an antioxidant function. . However, in the case of pure vitamin C, it is unstable and reacts sensitively depending on external factors such as water, oxygen, heat, etc., and when the content of pure vitamin C in the cosmetic composition is increased, the solubility is sharply decreased and there is a problem of precipitation.

Vitamin C derivative products are being released as substitutes to compensate for the shortcomings of pure vitamin C and to improve stability, but they have a problem of inefficiency compared to pure vitamin C due to high cost and the like. Accordingly, there is a need for research on a cosmetic composition that can maintain stability while containing a high content of pure vitamin C and prevent precipitation even when stored for a long time.
