Abstract

The invention relates to a tea-polyphenol-containing hydrogel used in after-sun reparation, and a preparation method thereof. The hydrogel is composed of the components of, by weight: 0.2-1.5% of beta-glucan, 0.1-1.0% of tea polyphenol, 2.0-8.0% of puccoon root extract, 2.0-8.0% of witch hazel extract, 4.0-8.0% of trehalose, 0.3-1.3% of a thickener, 5.2-12.0% of a humectant, 0.1-0.4% of a preservative, 0.1-0.5% of a chelating agent, 0.2-2.0% of a nutritional agent, 0.1-0.7% of a neutralizing agent, 0.05-0.3% of an essence, and balance of water. The hydrogel provided by the invention is non-toxic and non-irritating. With the synergetic effect among the active substances, skin reparation functions of the active components are enlarged, and an after-sun reparation effect is better.

Description

technical field [0001] The invention belongs to the field of skin care, and in particular relates to a water-based gel containing tea polyphenols for after-sun repair and a preparation method thereof. Background technique [0002] The skin is the largest organ of the human body, the first line of defense of the human body, covering the whole body, not only has defense protection, regulates body temperature, absorbs, secretes, excretes, participates in metabolism and immunity and other very important physiological functions, but also is the largest sensory expression of the human body Organs and the most striking aesthetic organs. [0003] Sunlight contains ultraviolet rays with different wavelengths. The short-wavelength ultraviolet rays are absorbed by the atmosphere, while UVA (long-wave dark spot effect ultraviolet rays) and UVB (medium-wave erythema effect ultraviolet rays) have strong penetrating power and can reach the earth's surface. [0004] UVA, with a wavelength ...
