AI Technical Summary

Benefits of technology

This patented technology makes it possible for people who use sunscreen products like screening up against harmful UV radiation without causing damage or discomfort during their activities. It also includes various benefits such as improved protection over time by reducing redness caused by exposure to light, increased durability due to reduced oxidative degradations, less side-effects when used at home (no risk), easy production processes that reduce environmental impact, etc., which make them more effective than previous methods.

Problems solved by technology

This patent describes various technical problem addressed by this patented product called Legaquinone (LFO) which blocks harmful solar waves while also providing antimicrobial properties against both acute and chronic forms of pollution such as water borne organisms including seaweeds, fishes, fungi, etc., without making everything bad at once.

Abstract

The invention discloses a polymeric natural polyphenol type sunscreen gel. The sunscreen gel comprises caffeic acid phenethyl ester nano particles and a gel substrate, wherein the gel substrate is a mixture of polyvinyl alcohol and water; and the mass percentage of the caffeic acid phenethyl ester nano particles in the gel substrate is 1-12%. The invention further discloses a preparation method ofthe polymeric natural polyphenol type sunscreen gel. The caffeic acid phenethyl ester nano particles in the sunscreen gel are high in stability and low in hematotoxicity and have good oxidation resistance; the preparation method is green, simple and convenient, the synthesis preparation process is not complicated, and the extracted and purified raw materials are all natural.
