preparation example Construction

[0051] In one embodiment, the preparation method of the Kudingcha extract is an ultrasonic immersion extraction method, comprising: sequentially drying Kudingcha, pulverizing, sieving, alcohol extraction, ultrasonic extraction, suction filtration and concentration, and vacuum drying step to obtain the Kudingcha extract.

[0052] In the present invention, each step of the Kudingcha extract is well known to those skilled in the art and is not particularly limited.

[0053] Kudingcha extract has the functions of lowering blood fat, lowering blood sugar, antibacterial, anti-oxidation, anti-aging, reducing heat and relieving summer heat. Tea polyphenols in polyphenols have certain sunscreen effects, and they also have antioxidant effects, so they are used in sunscreen products.

[0054] (green tea extract)

[0055] In the present invention, the green tea is a known strong natural antioxidant, which can effectively remove free radicals in the body, and it also contains rich tea po...

Abstract

The invention relates to the field of cosmetics, in particular to a sunscreen composition and application thereof. The sunscreen composition at least comprises an organic sunscreen agent, an inorganicsunscreen agent and a natural sunscreen agent, and the organic sunscreen agent comprises an aromatic ester ultraviolet light absorber with the refractive index of 1.4-1.6. The sunscreen composition provided by the invention is compounded with the organic sunscreen agent, the inorganic sunscreen agent and the natural sunscreen agent, full-wavelength protection and skin protection are achieved by absorbing and blocking the wavelength within the range of UVA and UVB, the natural sunscreen agent contains rich effective sunscreen components such as tea polyphenol, the sunscreen effect is providedwhile no irritation is caused to the human body, crystallization and precipitation are not likely to happen, the stability is good, and the film forming speed is high.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to a sunscreen composition and its application. Background technique [0002] Sunlight is a recognized cause of photodamage, photoaging, and skin cancer. Sunlight consists of ultraviolet (UV) (290-400nm), visible light (400-700nm) and infrared light (>700nm), of which 5% reach the Earth's surface For ultraviolet radiation, a smaller proportion penetrates the atmosphere and reaches the human skin. The effects of UV rays on the skin include erythema, sunburn, drug-induced phototoxicity, photoaging, and non-melanoma skin cancer, among others. In recent years, air pollution, especially the thinning of the ozone layer and the hole in the atmosphere will cause more damage to the skin caused by ultraviolet rays. Therefore, we need to use sunscreen products to protect our skin. Because the wavelength of ultraviolet light is very short, the energy is quite high, and the destructive power is ve...
