Problems solved by technology

[0009] At present, there is no report on the in-depth research of sealwort and its application in eye patch products. If sealwort can be developed and applied to the eye patch industry, it will not only help improve the visual fatigue of a large number of sub-healthy people, but also help the sealwort planting industry to further develop new products. Branch industry is of great significance to the promotion of sealwort industry

Embodiment 1

[0057] Hydrogel Formulation

[0058] Preparation method: add sodium hyaluronate to about 1 / 2 water, soak for 24 hours, fully dissolve, and obtain sodium hyaluronate gel. Add the remaining about 1 / 2 water to sodium hydroxide to make about 5wt% sodium hydroxide solution, mix sodium polyacrylate and carbomer 940 evenly, then add it to the sodium hydroxide solution, and swell overnight to obtain carbomer gel glue. Mix the dissolved sodium hyaluronate solution with the carbomer gel, add glycerin, stir well, and vacuum defoam to obtain a hydrogel.

[0059] Preparation of hydrogel A1: Weigh the following ingredients, 15 grams of sodium hyaluronate, 2.5 grams of sodium polyacrylate, 3 grams of carbomer, 13 grams of glycerin, and 58 grams of water. Prepare the hydrogel according to the above hydrogel preparation method.

[0060] Preparation of hydrogel A2: Weigh the following ingredients, 15 grams of sodium hyaluronate, 2 grams of sodium polyacrylate, 3.5 grams of carbomer, 12.5 gr...

[0071] Preparation of Polygonatum by Steaming and Sunning

[0072] The specific processing method of steamed and sun-dried Polygonatum is as follows: take fresh Polygonatum, wash, remove beards, and air-dry or air-dry. Slice Polygonatum, thickness 2-4mm. Put it in a steamer and steam for 4 hours, then turn off the heat and simmer for 2 hours, then take it out and dry it at 60°C to obtain the steamed and sun-dried Polygonatum.

[0073] Polysaccharide Extraction from Polygonatum Polygonatum

[0074] Take 100 grams of steamed and sun-dried Polygonatum, add 10 times the amount of water and decoct twice for 30 minutes each time, combine the extracts, concentrate to 100 ml, add absolute ethanol for precipitation to make the alcohol content reach 60v%, filter to remove the precipitate . Continue to add absolute ethanol to the filtrate to make the alcohol content of the filtrate reach 80v%, collect the precipitate, and dry to obtain Polygonatum polysaccharide N1 (60-80v% ethano...

Abstract

The invention discloses an eye patch containing polygonatum polysaccharide. The eye patch has a backing substrate layer, a gel layer and a protective film, wherein the gel layer is hydrogel with sodium hyaluronate as a main component; the gel layer contains 3-20%wt of a natural active ingredient extract; the natural active ingredient extract comprises polygonatum polysaccharide extract and snail extract; and the polygonatum polysaccharide accounts for 60wt% or more of the natural active ingredient extract. The eye patch takes the hydrogel made of the natural active ingredients, has good moisturizing and water-retaining properties, is mild and non-irritating, can improve blood circulation of periocular tissues, and has an obvious effect on relieving fatigue of eye tissues.

Description

technical field [0001] The invention relates to an eye patch, in particular to an eye patch containing Polygonatum polysaccharide, and belongs to the technical field of downstream industries of Polygonatum. Background technique [0002] In modern life and work, human activities are more and more closely related to monitors, and the time people spend facing monitors every day has increased significantly compared with the last century. The display is excited by voltage or current to display and emit different light to achieve image display. Compared with natural ambient light, there are a large number of blue light waves in the spectrum of electronic displays that easily cause visual cell fatigue, which directly leads to more and more prominent visual fatigue problems for users. [0003] Usually, people will experience dizziness and other bad feelings after watching the display for a long time. This is due to the physiological reasons of the human body on the one hand, and the...
