This invention discloses a mild and stable temperature-responsive microemulsion composition, its preparation method, and its applications, belonging to the fields of cosmetics and pharmaceutical technology. This invention uses a nonionic decyl glucoside and anionic sodium lauroyl glutamate, introducing tocopherol polyethylene glycol succinate and disodium EDTA, forming a dual stabilizing mechanism of "antioxidant + metal ion chelation," effectively protecting unstable active ingredients such as glycyrrhizin. Experiments show that in an accelerated test at 60℃, the retention rate of glycyrrhizin increased by more than 20%. The microemulsion composition prepared by this invention exhibits high stability, low irritation, and skin-targeted sustained-release properties.

This invention provides a polyfluorosiloxane alkyl polyurethane, its preparation method and application, and marine protective coatings, relating to the field of marine engineering protection technology. The polyfluorosiloxane alkyl polyurethane provided by this invention has a molecular chain comprising a soft segment component and a hard segment component. The soft segment component is a polylactic acid-polycarbonate copolymer with dihydroxyl-terminated ends; the hard segment component has polyfluorosiloxane side chains. Using the polyfluorosiloxane alkyl polyurethane provided by this invention, a biomimetic super-lubricating surface marine engineering protective coating with self-healing function and highly stable surface lubricant can be prepared. The chemically bonded polyfluorosiloxane side chain structure endows the coating with longer-lasting corrosion protection performance; the addition of mercapto-modified nano-silica further enhances the mechanical properties and UV aging resistance of the coating; simultaneously, the preparation method of this polyurethane is simple, and the reaction conditions are mild and efficient.
