Description

Alpinia officinarum and amomum tsao-ko sun-proof emulsion and preparation method thereof

Technical Field

The invention relates to the technical field of cosmetics, in particular to galangal tsaoko sunscreen emulsion and a preparation method thereof.

Background

The transmission capacity of ultraviolet rays (UVC section) with the wavelength of 200-280 nm in the sunlight only reaches the horny layer of the skin, the skin of a human body cannot be damaged, the irradiated human body can sterilize and disinfect, vitamin D is generated in the skin, and the skin is beneficial to body health. The transmission capacity of ultraviolet rays (UVB section, also called as a tanning section) with the wavelength of 290-320 nm can reach the epidermal layer of skin, so that the skin can be tanned with tanning, which is a main wave band for preventing people from sunburn; ultraviolet rays (UVA section, also called tanning section) with wavelength of 320-400 nm can reach the capability of transmitting dermis, and can tan the skin. In conclusion, harmful ultraviolet rays in the sunlight can gradually harden the dermis, dry the skin, lose elasticity, accelerate aging and wrinkle, and can also cause bright red spots on the surface of the skin, burning pain or swelling, even blistering and desquamation to become one of the pathogenic factors of skin cancer. In addition, facial freckles, chloasma, etc. are also aggravated by excessive sun exposure. People suffering from acne can accelerate the oxidation of acne tip under the irradiation of sunlight, and become blackhead to leave scars. Therefore, the key to protect skin, prevent skin aging and prevent skin cancer is to prevent the damage of ultraviolet rays in sunlight to skin. Sunscreen cosmetics are a class of cosmetics that protect the skin from sunlight, and that protect the skin from the harmful effects of ultraviolet radiation. With the improvement of living standard of people, the development and growth speed of sunscreen cosmetics in the international market is high, and various sunscreen cosmetics appear.

The sunscreen agents used in sunscreen cosmetics are of a wide variety and can be divided into two main categories: physical sunscreens and chemical sunscreens. Physical sunscreens are mainly used to reduce the contact of ultraviolet rays with the skin through scattering, thereby preventing the skin from being damaged by ultraviolet rays, such as titanium dioxide, zinc oxide, kaolin, talcum powder and the like; chemical sunscreens absorb energy from ultraviolet light and then release it as heat or harmless visible light, thereby protecting the skin from ultraviolet light, such as menthyl salicylate, menthyl benzoate, benzyl salicylate, etc. However, physical sunscreens tend to clog pores, while chemical sunscreens tend to irritate the skin.

Therefore, the problem to be solved by those skilled in the art is how to develop a natural sunscreen agent having sunscreen effect without irritating the skin.
